Home Remodel Checklist: Complete Planning Guide (2026)

Why You Need a Home Remodel Checklist

Every successful renovation starts the same way: with a plan. The projects that go sideways — blown budgets, missed deadlines, disputes with contractors — almost always trace back to skipped steps in the planning phase.

This is the home remodel checklist we give to every homeowner who contacts The5thwall for a project in Lawrence, Princeton, Hamilton, Ewing, or anywhere else in Mercer County. It covers every phase of a renovation from the first conversation you have with your spouse about "maybe updating the kitchen" all the way through your final walkthrough and beyond.

Whether you are planning a kitchen remodel, bathroom renovation, basement finishing project, or a whole-home renovation, this checklist applies. Print it out. Check the boxes. Follow the phases in order. You will save yourself time, money, and stress.

---

Phase 1: Pre-Planning (Before You Contact Anyone)

This is the phase most homeowners skip — and it is the single biggest reason renovations go wrong. Before you call a contractor, before you browse Pinterest, before you visit a showroom, you need clarity on what you want and what you can afford.

Define Your Goals and Priorities

Start by answering these questions honestly:

• Why are you renovating? Preparing to sell? Making the house work better for your family? Fixing something that is broken or outdated?
• What rooms need work? Is this a single-room project or a multi-room renovation?
• What is the end goal? A modern kitchen? A functional basement? An accessible bathroom for aging parents?

Your answers to these questions determine the scope of work, which determines the budget. A homeowner in West Windsor who wants to modernize a builder-grade kitchen before selling has very different needs than a family in Hopewell who is doing a whole-home renovation to stay in their forever home.

• [ ] Write down the primary reason for renovating
• [ ] List every room or area that needs work
• [ ] Rank rooms by priority (what matters most if budget gets tight?)
• [ ] Identify the end goal for each space

Set a Realistic Budget

The most common mistake we see across Central NJ is homeowners who set a budget based on what they *want* to spend rather than what the project *actually costs*. Here are real 2026 cost ranges for common projects in New Jersey:

These numbers reflect NJ pricing, which runs 15-25% above national averages due to higher labor costs, material delivery costs, and permitting requirements. For detailed breakdowns by project type, see our guides on kitchen remodel costs in NJ, bathroom remodel costs, and basement finishing costs.

The 20% rule: Whatever number you arrive at, add 20% as a contingency buffer. Renovations in older NJ homes — and most homes in Lawrence, Princeton, and Hamilton are 30-60 years old — regularly uncover surprises behind walls: outdated wiring, water damage, insufficient framing, asbestos, or lead paint. That contingency is not optional.

• [ ] Research costs for your specific project type
• [ ] Set a total budget including contingency (add 20%)
• [ ] Determine your maximum "do not exceed" number
• [ ] Separate "must-have" budget items from "nice-to-have" upgrades

Research Financing Options

Most homeowners in Mercer County do not pay for major renovations out of pocket. Here are the most common financing approaches:

Home Equity Loan — A fixed-rate loan against your home's equity. Best for homeowners who know their exact budget and want predictable payments. Rates in 2026 typically range from 7-9% for well-qualified borrowers.

HELOC (Home Equity Line of Credit) — A revolving credit line against your equity. Best for phased renovations where costs will come in over time. You only pay interest on what you draw. Rates are variable, typically prime + 1-2%.

Cash-Out Refinance — Replaces your existing mortgage with a larger one and gives you the difference as cash. Only makes sense if current rates are close to or below your existing rate.

Renovation Loan (FHA 203k or Fannie Mae HomeStyle) — Rolls renovation costs into your mortgage. Best for homeowners who recently purchased and want to renovate immediately. More paperwork and oversight than other options.

Personal Loan — Unsecured loan with higher rates (10-15%+). Best for smaller projects under $30,000 where you do not want to use your home as collateral.

Contractor Financing — Some contractors offer financing through lending partners. Read the terms carefully. The5thwall can connect you with trusted lending partners who specialize in NJ home renovation financing.

• [ ] Determine how you will pay for the project
• [ ] Get pre-approved or pre-qualified before contacting contractors
• [ ] Understand your monthly payment at the projected budget
• [ ] Factor financing costs into your total project budget

Create a Wish List vs. Must-Have List

This is the exercise that saves the most arguments during construction. Sit down with everyone in the household who has a say and create two lists:

Must-Haves: These are non-negotiable. The project does not happen without these items. Examples: new cabinets, updated electrical, a second bathroom, waterproofing.

Wish List: These are things you want if the budget allows. Examples: heated bathroom floors, a pot filler over the stove, custom built-in shelving, a wet bar in the basement.

When the inevitable change order or surprise cost comes up during construction, you will already know what can be cut and what cannot. This prevents the panicked decision-making that leads to regret.

• [ ] Create a "must-have" list with input from all decision-makers
• [ ] Create a "wish list" of upgrades and extras
• [ ] Rank wish list items by priority
• [ ] Assign estimated costs to wish list items (your contractor can help refine these later)

Timeline Expectations for NJ Projects

NJ renovations take longer than national averages due to permit processing times, inspection scheduling, and contractor availability. Here is what to expect:

• Kitchen remodel: 6-16 weeks depending on scope
• Bathroom remodel: 3-8 weeks
• Basement finishing: 6-12 weeks
• Whole-home renovation: 4-8 months
• Deck or patio: 2-6 weeks

Add 2-4 weeks for permits on any project that requires them. In busy seasons (spring and summer), add another 2-4 weeks for contractor availability. For a detailed breakdown, see our NJ renovation timeline guide.

• [ ] Set a target start date
• [ ] Set a realistic completion date (not a hopeful one)
• [ ] Identify any hard deadlines (holidays, events, school schedules)
• [ ] Build buffer time into your timeline

---

Phase 2: Design Phase

Once you know your goals, budget, and timeline, it is time to define exactly what you want built. This phase turns vague ideas into a concrete scope of work that a contractor can price accurately.

Gather Inspiration

You probably already have a Pinterest board or a folder of saved Instagram posts. Good. Now organize that inspiration into something useful:

• Group images by room — do not mix kitchen ideas with bathroom ideas
• Identify patterns — if every kitchen you saved has white cabinets and quartz countertops, that tells you something
• Note specific products — if you see a faucet or tile you love, find the brand and model number
• Be realistic — a $200,000 kitchen in Architectural Digest is aspirational, not a plan for a $50,000 budget

• [ ] Organize inspiration images by room
• [ ] Identify your preferred style (modern, transitional, traditional, farmhouse)
• [ ] Note specific materials, colors, and finishes you are drawn to
• [ ] Share your inspiration with your contractor during consultations

Decide Scope of Work

This is where you draw the line between what you are doing and what you are not doing. Scope creep is the number one budget killer in home renovations.

Layout changes vs. cosmetic updates: Moving walls, relocating plumbing, and changing the footprint of a room costs significantly more than updating surfaces and fixtures within the existing layout. A kitchen remodel that keeps the same layout might cost $35,000-$50,000, while the same kitchen with walls removed and plumbing relocated jumps to $75,000-$120,000.

Structural work: Removing load-bearing walls, adding windows, or modifying the roofline requires structural engineering and additional permits. Budget accordingly.

Systems updates: If your home is more than 30 years old (common in Ewing, Lawrence, and Hamilton), your renovation might reveal outdated electrical panels, galvanized plumbing, or inadequate insulation. Decide now whether you will address these if they come up — do not wait until the walls are open.

• [ ] Define exactly what is being renovated and what is not
• [ ] Decide if layout changes are in scope
• [ ] Identify potential systems upgrades (electrical, plumbing, HVAC)
• [ ] Document the scope in writing (this becomes the basis for contractor bids)

Choose Materials and Finishes

Making material selections before construction starts prevents delays and budget surprises. Your contractor should help with this, but having preferences identified speeds up the process.

Key selections to make:

• Cabinetry — stock, semi-custom, or custom? Material and finish?
• Countertops — quartz, granite, marble, butcher block, solid surface? See our quartz vs. granite comparison
• Flooring — hardwood, LVP, tile, concrete? See our hardwood vs. LVP guide and best flooring options
• Tile — for backsplashes, shower walls, and floors
• Fixtures — faucets, sinks, toilets, showerheads
• Hardware — cabinet pulls, door handles, hinges
• Lighting — recessed, pendant, under-cabinet, sconces
• Paint colors — see our paint color guide for renovations
• Appliances — brands, models, and finishes (if kitchen)

• [ ] Select or narrow down cabinetry options
• [ ] Select or narrow down countertop material
• [ ] Select or narrow down flooring material
• [ ] Choose tile for applicable areas
• [ ] Select plumbing fixtures
• [ ] Select hardware and lighting
• [ ] Select appliances (if applicable)
• [ ] Get pricing on all selections to verify they fit your budget

Get Preliminary Plans if Needed

Not every project needs architectural drawings, but these do:

• Any project that changes the footprint of the home
• Any project that removes or modifies load-bearing walls
• Major kitchen remodels with layout changes
• Basement finishing projects with bathrooms or egress windows
• Any project requiring structural permits

An architect or designer in NJ typically charges $2,000-$8,000 for renovation plans depending on complexity. Your general contractor may also offer design-build services that include plan development.

• [ ] Determine if architectural or design plans are needed
• [ ] Get referrals for architects or designers (or use your contractor's design-build service)
• [ ] Budget for design fees
• [ ] Review and approve plans before moving to the bidding phase

---

Phase 3: Hiring Phase

This is the phase that determines whether your renovation will be a good experience or a nightmare. The contractor you choose matters more than almost any other decision you will make. For an in-depth guide, read our article on how to choose a general contractor.

Research Contractors

Start with referrals from people you trust — neighbors, coworkers, family members who have had work done recently. Then verify everything independently.

• [ ] Get referrals from at least 3 people you know
• [ ] Check online reviews (Google, Yelp, Houzz, Angi)
• [ ] Visit contractor websites and review portfolio work
• [ ] Verify NJ contractor license (search at NJ Division of Consumer Affairs)
• [ ] Confirm active general liability and workers' compensation insurance
• [ ] Check for complaints with the NJ Better Business Bureau

Get 3+ Bids

Never hire the first contractor you talk to. Get at least three written bids for the same scope of work.

What a proper bid should include:

• Detailed scope of work (not just "remodel kitchen")
• Itemized costs by trade (demolition, framing, electrical, plumbing, finishes, etc.)
• Material specifications and allowances
• Timeline with start date and estimated completion date
• Payment schedule tied to milestones
• Who handles permits and inspections
• Warranty information
• How change orders are handled

Red flags in bids:

• A bid that is dramatically lower than the others (usually means they are cutting corners or will hit you with change orders)
• Vague line items like "labor and materials" with no breakdown
• Verbal-only bids with nothing in writing
• No mention of permits or inspections
• Demands for more than 10-15% upfront before any work begins

• [ ] Contact at least 3 contractors for bids
• [ ] Provide the same scope of work document to each
• [ ] Review each bid line by line
• [ ] Ask clarifying questions about anything vague
• [ ] Compare bids on an apples-to-apples basis (same scope, same materials)

Check NJ Licenses and Insurance

In New Jersey, any contractor performing work valued at more than $500 must be registered with the NJ Division of Consumer Affairs as a Home Improvement Contractor (HIC). This is state law, not optional.

Verify:

• Active NJ Home Improvement Contractor registration
• General liability insurance (minimum $500,000, preferably $1,000,000+)
• Workers' compensation insurance (required if they have employees)
• Any specialty licenses required for your project (plumbing, electrical, HVAC)

Ask for certificates of insurance and verify them directly with the insurance company — not just the contractor's copy. Read more in our guide on licensed contractors in NJ and common renovation mistakes to avoid.

• [ ] Verify NJ HIC registration for your chosen contractor
• [ ] Request and verify certificates of insurance
• [ ] Confirm workers' comp coverage
• [ ] Verify specialty licenses for plumbing, electrical, and HVAC subcontractors

Review Contracts

Read every word of the contract before you sign. A solid NJ renovation contract should include:

• Full legal names and addresses of both parties
• NJ HIC registration number
• Complete scope of work matching the approved bid
• Total contract price with itemized breakdown
• Payment schedule tied to completion milestones (never a large lump sum upfront)
• Start date and estimated completion date
• Specification of all materials (brands, models, colors)
• Change order process (must be in writing, signed by both parties)
• Warranty terms
• Dispute resolution process
• The NJ 3-day right of rescission notice (required by law)

• [ ] Read the entire contract before signing
• [ ] Verify the scope matches what was discussed and bid
• [ ] Confirm the payment schedule is tied to milestones
• [ ] Ensure change order process is clearly defined
• [ ] Verify the NJ right of rescission notice is included
• [ ] Have questions answered before signing

Set Payment Schedule

A standard NJ renovation payment schedule looks like this:

1. 10-15% deposit at contract signing (never more — this is an NJ red flag)
2. 25-30% at material delivery / start of demolition
3. 25-30% at rough-in completion (framing, plumbing, electrical before drywall)
4. 20-25% at substantial completion
5. 5-10% final payment after punch list completion and final inspection

Never pay in full before the work is done. The final payment is your leverage to ensure the punch list gets completed.

• [ ] Agree on a milestone-based payment schedule
• [ ] Ensure no single payment exceeds 30% of the total
• [ ] Keep the final 5-10% until all punch list items are resolved
• [ ] Use checks or traceable payment methods (not cash)

Phase 4: Pre-Construction

You have your plan, your contractor, and your contract. Now it is time to prepare for construction to begin.

NJ Permit Requirements by Project Type

Permits are not optional in New Jersey. Working without required permits can result in fines, forced removal of work, and problems when you try to sell your home. Your contractor should handle permit applications, but you should understand what is required.

Permit timelines vary by municipality. Lawrence Township and Princeton tend to process permits faster than some surrounding towns, but always assume 2-4 weeks minimum for any permit that requires plan review. For a deep dive, see our guides on NJ renovation permits and NJ building permits in 2026.

• [ ] Confirm which permits are required for your project
• [ ] Verify your contractor is handling permit applications
• [ ] Ask for copies of all permit applications
• [ ] Build permit processing time into your timeline

HOA Approval If Applicable

If you live in a community with a homeowners association — common in West Windsor, Robbinsville, and parts of Hamilton and Lawrence — you may need HOA approval before starting exterior work or certain interior projects.

• [ ] Check if your community has an HOA
• [ ] Review HOA covenants for renovation restrictions
• [ ] Submit architectural review applications if required
• [ ] Get written approval before starting work

Order Materials with Long Lead Times

Some materials take weeks or months to arrive. Ordering these before construction starts prevents costly delays.

Common long-lead-time items:

• Custom cabinetry: 6-12 weeks
• Special-order windows and doors: 4-10 weeks
• Custom countertops (after template): 2-4 weeks
• Specialty tile: 3-8 weeks
• Professional-grade appliances: 4-12 weeks
• Custom lighting fixtures: 3-6 weeks

• [ ] Identify all materials with lead times over 2 weeks
• [ ] Place orders for long-lead items before construction starts
• [ ] Confirm delivery dates and coordinate with your contractor
• [ ] Arrange secure storage for materials delivered before installation

Plan Temporary Living Arrangements If Needed

A kitchen remodel means no kitchen for 6-12 weeks. A whole-home renovation might make the house unlivable. Plan ahead.

• [ ] Determine if you can live in the house during construction
• [ ] Set up a temporary kitchen (microwave, mini fridge, hot plate) if staying during a kitchen remodel
• [ ] Arrange alternative housing if the project requires it
• [ ] Budget for temporary living costs if applicable

Set Up Dust Barriers and Protect Belongings

Construction generates an enormous amount of dust, noise, and debris. Protect your home and belongings before work starts.

• [ ] Move furniture and belongings out of the construction zone
• [ ] Your contractor should set up plastic dust barriers between work areas and living spaces
• [ ] Cover or move anything valuable near the work zone
• [ ] Establish a path for workers that minimizes impact on your living areas
• [ ] Remove or protect wall art, curtains, and light fixtures in adjacent rooms
• [ ] Consider temporary storage for furniture and large items

---

Phase 5: During Construction

Construction is underway. Your job now is to stay informed, document everything, and communicate clearly with your contractor.

Communicate with Your Contractor Regularly

Establish a communication rhythm from day one. A good contractor will keep you updated proactively, but you should also:

• Weekly check-ins — schedule a standing meeting (even 15 minutes) to review progress, upcoming work, and any decisions needed
• Decision log — keep a running list of decisions you have made and when you made them
• Single point of contact — communicate with the project manager or lead contractor, not individual subcontractors
• Preferred method — agree on how you will communicate (text, email, phone, app) and stick to it

• [ ] Establish a weekly check-in schedule with your contractor
• [ ] Set up a shared communication channel (text thread, email chain, or project app)
• [ ] Identify the single point of contact on the contractor's side
• [ ] Keep a running decision log

Document Everything

This is not about trust — it is about protection. Thorough documentation protects both you and your contractor.

• [ ] Take photos of the work area before construction starts (baseline documentation)
• [ ] Take weekly progress photos from the same angles
• [ ] Photograph any surprises discovered during demolition (old wiring, water damage, mold)
• [ ] Save all emails, texts, and written communications
• [ ] Keep a file of all invoices, receipts, and payment records
• [ ] Document any material substitutions and who approved them

Handle Change Orders Properly

Change orders are changes to the original scope of work. They are normal — almost every renovation has at least one. But they must be handled correctly.

The rule: nothing changes without a written, signed change order.

A proper change order should include:

• Description of the change
• Reason for the change
• Cost impact (increase or decrease)
• Timeline impact
• Signatures from both homeowner and contractor

Do not approve verbal change orders. Do not let work proceed on a change until both parties have signed off. This is the single most common source of renovation disputes.

• [ ] Understand the change order process in your contract
• [ ] Require all changes in writing before work proceeds
• [ ] Review cost and timeline impact of each change order
• [ ] Sign off on changes only after understanding the full impact
• [ ] Track cumulative change order costs against your contingency budget

Inspect Work at Milestones

You do not need to be a construction expert to inspect progress. Your contractor should invite you to review work at key milestones:

Before drywall goes up — This is your last chance to see the framing, plumbing rough-in, electrical wiring, and insulation. Verify everything is where it should be. Take photos.

After drywall and paint — Check for smooth walls, clean corners, and proper finish work.

After fixture installation — Test faucets, lights, outlets, and switches.

Before final payment — Complete a thorough walkthrough (covered in Phase 6).

Municipal inspectors will also inspect permitted work at key stages. Your contractor is responsible for scheduling these inspections.

• [ ] Schedule milestone inspections with your contractor
• [ ] Attend the pre-drywall walkthrough
• [ ] Verify rough-in work matches the approved plans
• [ ] Confirm municipal inspections are being scheduled and passed

Keep Receipts and Records

Organized records serve three purposes: tracking your spending in real time, supporting warranty claims later, and increasing your home's value documentation for future resale.

• [ ] Create a folder (physical or digital) for all project documents
• [ ] File every receipt, invoice, and payment record
• [ ] Keep copies of all permits and inspection reports
• [ ] Save product manuals and warranty cards for all installed items
• [ ] Track spending against your budget weekly

---

Phase 6: Final Walkthrough and Punch List

The project looks finished. Do not sign off yet. The final walkthrough is where you verify that everything was built correctly, works properly, and matches what you agreed to in the contract.

Create a Comprehensive Punch List

Walk through every inch of the renovated space with your contractor and note anything that is not right. Common punch list items include:

• Paint touch-ups needed
• Trim or molding gaps
• Cabinet doors that do not close properly
• Scratches or damage to new surfaces
• Grout that needs repair
• Caulking that needs to be redone or cleaned
• Outlets or switches that do not work
• Doors that stick or do not latch
• Hardware that is loose or missing

Do this walkthrough during daylight hours — you will see imperfections more clearly in natural light.

• [ ] Schedule the final walkthrough during daylight hours
• [ ] Walk through every room and area that was part of the project
• [ ] Document every item that needs attention (photos + written list)
• [ ] Agree on a timeline for punch list completion with your contractor
• [ ] Do not make final payment until punch list items are resolved

Test Everything

Do not assume it works — verify it.

• [ ] Test every electrical outlet in the renovated area
• [ ] Test every light switch and dimmer
• [ ] Test every faucet (hot and cold) and check for leaks under sinks
• [ ] Flush every toilet and check for proper function
• [ ] Run the dishwasher through a full cycle
• [ ] Test the garbage disposal
• [ ] Open and close every door and window — verify smooth operation and proper locking
• [ ] Open and close every cabinet door and drawer
• [ ] Test all appliances
• [ ] Check that HVAC reaches the renovated areas properly
• [ ] Run exhaust fans and verify they vent properly
• [ ] Check for water pressure issues

Verify Permits Are Signed Off

This is critical and often overlooked. Open permits attached to your property can cause serious problems when you try to sell your home or refinance.

• [ ] Confirm all required inspections have been completed and passed
• [ ] Obtain copies of all signed-off inspection cards or certificates
• [ ] Verify with your municipality that all permits are closed
• [ ] Keep copies of all final inspection documents

Get Warranty Documentation

Your renovation should come with multiple layers of warranty protection:

• Contractor workmanship warranty — typically 1-5 years covering labor and installation defects
• Manufacturer warranties — covering materials, appliances, fixtures, and products
• Subcontractor warranties — plumbing, electrical, and HVAC work may carry separate warranties

• [ ] Obtain the contractor's written workmanship warranty
• [ ] Collect all manufacturer warranty documents and registration cards
• [ ] Register products that require warranty registration
• [ ] Organize all warranty documents in one location
• [ ] Note warranty expiration dates in your calendar

Get Lien Waivers from All Subcontractors

A lien waiver is a document signed by a contractor or subcontractor confirming they have been paid in full for their work on your property. Without lien waivers, a subcontractor who was not paid by your general contractor could place a lien on your home — even though you paid the GC in full.

• [ ] Request lien waivers from your general contractor
• [ ] Request lien waivers from all subcontractors who worked on the project
• [ ] Request lien waivers from all material suppliers
• [ ] Keep lien waivers on file permanently

---

Phase 7: Post-Renovation

The work is done, the punch list is complete, and you are enjoying your new space. A few final steps protect your investment for years to come.

Final Payments After Satisfaction

Release the final payment only after:

• All punch list items are complete
• All permits are signed off
• You have received all warranty documentation
• You have received all lien waivers
• You are satisfied with the work

• [ ] Verify all punch list items are resolved
• [ ] Confirm all permits are closed
• [ ] Confirm all lien waivers are received
• [ ] Make the final payment
• [ ] Get a final receipt marked "paid in full"

File Warranty Information

Create a permanent file — physical or digital — for everything related to your renovation:

• [ ] Create a "home renovation" folder in a safe location
• [ ] File all warranty documents organized by trade and product
• [ ] Include a copy of the final contract and all change orders
• [ ] Include all inspection reports and permit close-out documents
• [ ] Include before and after photos
• [ ] Include contact information for your contractor and all subcontractors

Update Home Insurance

A major renovation increases your home's value and replacement cost. If you do not update your homeowner's insurance, you may be underinsured.

• [ ] Contact your insurance agent about the completed renovation
• [ ] Provide documentation of the work completed and the investment amount
• [ ] Update your coverage to reflect the increased replacement cost
• [ ] Ask about any available discounts (new roof, updated electrical, security systems)

Save Documentation for Resale

When you eventually sell your home, buyers and their inspectors will want to see documentation of major renovations. Proper records can increase your home's value and speed up the sales process. For data on which renovations deliver the best return, see our home renovation ROI guide for NJ.

• [ ] Keep a summary of all renovations completed (dates, scope, cost)
• [ ] Maintain before-and-after photos in a presentable format
• [ ] Keep permit records accessible for future buyers
• [ ] Keep warranty documents transferable where applicable

Common Mistakes That Blow Up NJ Renovations

We have completed hundreds of projects across Lawrence, Princeton, Hamilton, Ewing, Pennington, Hopewell, West Windsor, and Robbinsville. These are the mistakes we see most often — and the ones this checklist is specifically designed to prevent. For even more detail, read our full guide on home renovation mistakes to avoid in NJ.

1. Skipping the budget contingency. Every. Single. Time. The homeowner who budgets $50,000 and does not plan for surprises ends up at $55,000-$60,000 and stressed about it. The homeowner who budgets $50,000 with a $10,000 contingency ends up at $55,000 and comfortable.

2. Hiring based on lowest price. The cheapest bid is almost never the best value. That low number usually means cut corners, unlicensed subcontractors, skipped permits, or change orders that bring the final price above the mid-range bids anyway.

3. No written change orders. "While you are at it, can you also..." is a sentence that has cost NJ homeowners millions of dollars in collective unexpected renovation costs. If it is not on a signed change order, it does not exist.

4. Choosing materials during construction. When your contractor is waiting for you to pick tile and you have not started looking yet, that is a delay that costs everyone money. Make selections before the hammer swings.

5. Not verifying permits are closed. We have seen homeowners discover at closing that a previous renovation has open permits from 15 years ago. Always verify permits are closed and keep the documentation.

---

When to Start Planning

The best time to start this checklist is 3-6 months before you want construction to begin. That gives you enough time to:

• Work through the pre-planning and design phases without rushing
• Get multiple bids and compare them carefully
• Secure financing
• Allow for permit processing
• Order long-lead-time materials

If you are thinking about a renovation in Mercer County for this year or early next year, now is the time to start Phase 1.
