A new-construction home inspection checklist should cover the site, structure, finishes, plumbing, HVAC, electrical systems, appliances, documents and contract compliance before you sign closing papers. Yes, you should still arrange a buyer-side inspection and a final walk-through even when the municipality has approved the work or the builder says the home passed inspection. A code inspection asks whether the building meets local minimum requirements; your inspection asks whether the home matches your contract, selections, plans and workmanship expectations.
Turn on every required utility before the appointment, record each defect in a written punch list, and get the builder’s response, responsible trade and completion date in writing. Maryland’s consumer guidance recommends a final walk-through before settlement to confirm that work was completed properly under the contract, while New Jersey’s guidance explains that building-department plans do not determine everything the builder must provide.

Why does a new-construction home need a buyer inspection?
New construction still benefits from an independent inspection because several different inspections answer different questions. A municipal inspector checks compliance with adopted building, electrical, plumbing, mechanical and life-safety codes. A buyer’s inspector or other qualified building professional examines visible workmanship, operation and the promises in the purchase contract.
The distinction matters because a house can receive a code approval and still have a scratched cabinet, an uninstalled option, a leaking drain, a misaligned door or a finish that does not match the written specifications. The New Jersey Department of Community Affairs states that plans filed with the building department do not determine everything the builder must provide; the contract does. Keep both the municipal record and your contract-based inspection in the closing file.

| Inspection or record | Who performs it | Main question answered | Useful output |
|---|---|---|---|
| Municipal code inspections | Local building department or its inspector | Does the work meet applicable minimum code requirements? | Inspection approvals, correction records and, where required, a certificate of occupancy |
| Builder walk-through | Builder or builder’s representative with the buyer | What remains incomplete or needs correction before handover? | Builder’s punch list and orientation information |
| Independent buyer inspection | Inspector, licensed engineer, architect or another qualified professional, subject to local rules | Does the visible home operate properly and match the contract, plans and specifications? | Condition report, photographs and a buyer-controlled punch list |
A practical approach is to use municipal records as evidence of required approvals, attend the builder’s walk-through, and arrange an independent inspection early enough to negotiate or document unresolved items.
What should you do before the inspection appointment?
Preparation determines how much of the home can actually be checked. Complete these steps before anyone arrives:
- Read the controlling documents. Bring the executed purchase contract, specifications, options and selections, change orders, allowances, plot or site plan and any written promises. Make a room-by-room list of the materials, fixtures, appliances and upgrades that were supposed to be installed.
- Ask the builder for the procedure. Confirm the appointment window, who may attend, whether an independent inspector is permitted, which areas are accessible, and whether roof, attic or crawl-space access has conditions. Ask for the status of the final municipal inspections, certificate of occupancy or equivalent approval, and the builder’s warranty booklet and claim instructions.
- Schedule a qualified professional. Miami-Dade County recommends bringing someone knowledgeable in the building trade, such as a licensed engineer or architect. Use a professional whose scope and qualifications fit the property and your jurisdiction; an optional outlet tester can document receptacle checks but cannot replace an inspector or code official.
- Activate utilities. Electricity, water, gas and other required services must be on for meaningful tests of faucets, drains, heating, air conditioning, appliances and installed systems. If a utility is unavailable, mark that item as not tested rather than treating it as satisfactory.
- Allow time for a second look. Ask how defects will be corrected and how reinspection will be arranged. A rushed appointment makes it easier to miss a nonworking fixture or to lose the opportunity to verify a repair before settlement.
How do you inspect the exterior, site and structure?
Start outside because drainage, access and visible deviations can affect the home before you enter it. Compare what is built with the approved plans and written specifications, and photograph anything that differs.
- Site and grading: Look for standing water, soil that slopes toward the foundation, blocked swales, damaged paving and incomplete or missing landscaping required by the contract. Note downspouts that discharge beside the foundation or toward walkways.
- Foundation and visible structure: Look for accessible cracks, openings, damaged masonry, unfinished sealants and signs of water entry. Do not climb or enter an unsafe area to reach a higher or concealed component; record the limitation for follow-up by a qualified professional.
- Roof and drainage: From safe ground-level or approved access, look for chipped, cracked or loose roof coverings, displaced flashing, incomplete penetrations and signs of leakage in accessible areas. The Miami-Dade walk-through list specifically calls for checking roof coverings and leakage where accessible.
- Doors and windows: Open, close, latch and lock each accessible unit. Check alignment, damaged glass, screens, weather seals, caulking and gaps. A window that sticks or will not latch belongs on the punch list even if it is otherwise installed.
- Plans and promised features: Verify exterior outlets, hose bibs, steps, railings, garage features, fencing and other options against the contract and selections. A missing feature is a contract discrepancy, not merely a cosmetic observation.
How do you test plumbing, drainage and HVAC?
Run the systems with utilities active and observe both operation and evidence of leakage. Test fixtures one at a time and then under normal simultaneous use where practical.

- Run every faucet, including utility sinks and exterior hose bibs where accessible. Check hot and cold operation, water pressure changes, loose handles, supply-line leaks and noisy or vibrating pipes.
- Operate toilets, tubs and showers. Confirm that toilets fill and stop, fixtures drain without backing up, tub and shower controls divert correctly, and there is no leakage at valves, traps or supply connections.
- Test floor drains and other drains by adding enough water to confirm discharge. A slow drain, gurgling, overflow or foul odor should be documented by location.
- Operate heating and air-conditioning equipment in the available modes. Check that conditioned air reaches each accessible register, thermostats respond, equipment starts and stops normally, and condensate drains do not leak or discharge into an inappropriate area.
- Inspect visible water heaters, shutoff valves, exposed piping and drain pans for leaks, missing insulation or incomplete connections. Do not remove covers or operate gas components unless the qualified professional is authorized and equipped to do so.
Miami-Dade’s new-home walk-through list emphasizes testing plumbing, drains and HVAC after utilities are on. Record a system as “not tested—water/gas/electricity unavailable” when that condition prevents a meaningful check.
What electrical, appliance and life-safety items should you check?
Test every accessible control and device, then compare the installation with the contract and local requirements. Do not open energized equipment or bypass a protective device.

- Operate each accessible light fixture, switch, ceiling fan and exterior light. Note flickering, loose fixtures, switches that control the wrong light and lights that do not work.
- Test accessible receptacles with an appropriate tester and check required GFCI or AFCI protection as applicable to local code. A tripped protective device, dead outlet or outlet that cannot be reset belongs in the report.
- Run builder-supplied appliances through a normal cycle where possible: range, oven, cooktop, microwave, dishwasher, refrigerator water or ice features, garbage disposal, washer, dryer and ventilation hood. Confirm that manuals, accessories and manufacturer labels are present.
- Operate doorbells, intercoms, garage-door openers, security devices, smoke alarms, carbon-monoxide alarms and other installed systems. Ask who will program or transfer monitoring services.
- Check the electrical panel directory, accessible disconnects and service labels for completeness. Leave panel covers and wiring work to qualified personnel.
How do you check interior finishes and workmanship?
Inspect every room in good light and compare the installed work with your selections. Defects are easier to resolve when each entry identifies an exact location and includes a photograph.
- Open and close cabinet doors and drawers; check hinges, slides, alignment, hardware, shelves, countertops, backsplashes and vanities for damage or unfinished edges.
- Examine walls, ceilings, trim and paint for cracks, dents, overspray, visible joints, inconsistent coverage and missing caulk. Check window and door caulking, especially at corners and transitions.
- Walk the flooring and inspect tile, grout, transitions, thresholds, stairs and railings for damage, lippage, loose pieces or incomplete installation.
- Look at countertops, shower surrounds and counter tiles for chips, scratches, open joints and poor seals. Run water at sinks while checking the cabinet below.
- Where safely accessible, inspect attic insulation, ventilation, visible ductwork and signs of moisture. Do not walk on unsupported ceiling surfaces or enter a confined or hazardous space.
- Photograph each defect with a wide image showing the room and a close image showing the condition. Assign a number and location, such as “Photo 12—second-floor hall bath, east wall, missing caulk at tub corner.”
How should you create and use the punch list?
A punch list converts observations into obligations that can be tracked. Maryland’s Attorney General describes it as the list of work that must be completed or fixed before settlement.

| Field | What to enter |
|---|---|
| Location | Room, elevation, floor, fixture or exterior area |
| Defect or incomplete work | Plain description of what is wrong or missing |
| Photo number | Matching image or video reference |
| Contract reference | Specification, selection, change order, plan detail or code-related item, if applicable |
| Builder response | Accepted, disputed, to be evaluated or other written response |
| Responsible trade | Builder, electrician, plumber, HVAC contractor, flooring installer or other assigned party |
| Promised completion date | A specific date or milestone, not “soon” |
| Reinspection status | Open, repaired, buyer verified, or still unresolved |
Ask the builder or representative to acknowledge the list in writing and keep the dated copy with the closing documents. Reinspect repaired items before settlement when possible: operate the fixture again, look at the repaired finish in good light and update the status rather than deleting the original entry.
Can unresolved inspection items delay closing or require an escrow?
Possibly, but the purchase contract and local closing rules control the remedy. Do not assume that a verbal promise, a municipal approval or a builder’s standard practice gives you the right to delay settlement.
Before signing, ask the closing agent or attorney to identify what the contract permits: completion before closing, a written post-closing agreement, an escrow or holdback, a credit, or a warranty claim. Put the exact scope, responsible party, deadline, access arrangement and consequence of nonperformance in a signed document. If the builder will not acknowledge a significant defect or a missing contractual feature, obtain jurisdiction-specific legal advice before waiving a condition or signing a settlement statement.
Use the code record and the contract for their separate purposes. New Jersey’s consumer guidance makes clear that code officials determine compliance with code, while the contract determines what the builder must provide. A passing final inspection therefore does not erase a punch-list item involving workmanship, finish quality or an option promised in writing.

Which documents should you collect at settlement?
Collect the complete handover file, not just keys and a warranty brochure. Keep paper and electronic copies in a location you can access after moving.
- Executed purchase contract, specifications, selections, allowances, change orders and the acknowledged punch list.
- Approved plans and any available as-built drawings, plot documents or site records. Ask the local building department what records it can release.
- Certificate of occupancy or equivalent final-approval evidence required by the jurisdiction. Requirements differ locally; Montgomery County, Maryland, for example, identifies footing, foundation, framing, final electrical, final plumbing and final building certifications in its settlement process.
- Builder, general contractor and subcontractor contact information where available, including the correct warranty and service channels.
- Appliance manuals, model and serial numbers, registration information, keys, remotes and completed warranty certificates.
- Builder warranty booklet, coverage terms, exclusions, claim procedure, notice method and all deadlines. New Jersey explains that warranty terms are set out in the booklet supplied at closing or settlement.
- Signed records of agreed repairs, credits, escrows or post-closing obligations, including completion dates and reinspection rights.
Miami-Dade’s guidance also recommends inspecting with the developer or its designee before signing closing documents. Treat that walk-through as an additional handover step, not as a substitute for reviewing your own written records.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What should you do if a defect appears after closing?
Report it promptly through the builder’s required channel and preserve proof of notice. Describe the location and condition, attach dated photographs, identify when it was discovered and request a written response or service appointment.
Follow the warranty booklet rather than relying on a general assumption about coverage or timing. Coverage, exclusions, deadlines and remedies vary by contract and jurisdiction. Miami-Dade advises notifying the developer of construction defects within the first year after closing, but that is a local example, not a nationwide deadline. Keep copies of every email, portal submission, letter, invoice and access appointment, and update the original punch list so unresolved items remain traceable.

How do the three inspection approaches fit together?
No single walk-through answers every question. Compare the approaches by buyer representation, contract coverage, physical access, testing with utilities on, documentation quality, timing and follow-up.
| Approach | Strength | Limitation | Best use |
|---|---|---|---|
| Municipal inspection records | Shows required code inspections and approvals | Usually does not evaluate every contract promise, cosmetic defect or owner preference | Confirm jurisdictional approvals and identify missing final records |
| Builder walk-through | Direct access to the builder’s representative and handover process | The builder is not the buyer’s independent advocate, and the appointment may follow builder rules | Learn systems, identify obvious incomplete work and document the builder’s response |
| Independent inspection | Buyer-focused review of visible conditions, operation and contract discrepancies | Cannot see concealed conditions or guarantee future performance; scope and access vary | Create a defensible punch list before closing and guide reinspection |
What mistakes commonly weaken a final inspection?
- Inspecting with utilities off: You cannot meaningfully evaluate drains, HVAC, appliances or many electrical features. Reschedule or mark those items untested.
- Relying on the certificate of occupancy: Approval is not proof that every selection, finish or contract obligation is complete.
- Using verbal promises: If a repair matters, record its scope, owner and deadline in a signed or acknowledged document.
- Failing to compare selections: Bring the specifications and change orders; memory is not a reliable substitute for the contract.
- Deleting original defects after a repair: Keep the original entry and add the repair date and verification result.
- Entering unsafe areas: Do not climb roofs, walk unsupported attic surfaces or open energized equipment merely to complete a checklist.
- Missing warranty deadlines: Read exclusions and notice instructions at settlement, then calendar the applicable dates.
Frequently Asked Questions
What if the utilities are not turned on for the scheduled walk-through?
Ask the builder and closing team to arrange activation or a second appointment, and mark every affected system as “not tested” in the written record. Do not treat a faucet, drain, HVAC unit or appliance as satisfactory simply because it could not be operated.
How should I photograph defects so the builder can find them?
Take one wide photograph that identifies the room and one close photograph that shows the defect, then assign a matching number in the punch list. Add a precise location such as a wall, elevation, fixture or floor so the repair can be verified without guesswork.
Can I sign closing documents when punch-list work remains?
That depends on the contract and local closing rules. If work will continue after settlement, require a signed document stating the exact scope, completion date, access process and any escrow, credit or warranty remedy instead of relying on an oral assurance.
How do I notify the builder about a defect discovered after moving in?
Use the warranty booklet’s required portal, email, form or mailing method and keep proof showing when the notice was sent. Include photographs, the location, discovery date and a clear request for inspection; local examples and warranty terms may impose deadlines that differ from one another.
