Inspecting New Construction in Claremont: Yes, You Still Should

The most common objection to inspecting a brand-new house is that it has already been inspected - repeatedly, by the city, at every stage. That is true and it is not the same thing. A MUNICIPAL INSPECTION CONFIRMS CODE COMPLIANCE. It is a floor, performed on behalf of public safety, at defined checkpoints, on a schedule that serves the permit rather than you. It does not evaluate workmanship quality, it does not test whether the system was commissioned correctly, and it does not represent your interests in a dispute. A private inspection is the one performed for you.

This article deepens the new-construction guide and sits alongside the new-build process guide, which covers the contract side of the same purchase. What you find here is also what fills the list in the punch list and walkthrough guide.

The two inspections that matter most

THE PRE-DRYWALL INSPECTION is the one buyers skip and later wish they had not, because it is the only chance to look at the bones. Once drywall is hung, the framing, the fasteners, the plumbing runs, the electrical rough-in, the ductwork, the insulation, the fire blocking, the flashing details and the waterproofing behind the finished surfaces all disappear for the life of the house. An inspector at this stage is looking at whether things were done well, not merely whether they exist: whether penetrations were sealed, whether runs are supported, whether the assembly matches the plan, whether anything was cut or notched in a way that will matter later.

Ask early whether the builder permits it, ask what notice they need, and put it in the calendar as soon as the schedule firms up. This inspection has a short window and no second chance. If the builder does not permit a private pre-drywall inspection, that is itself information worth weighing - not automatically a red flag, since some builders have liability and site-access policies, but a question worth asking directly and hearing the answer to.

THE PRE-CLOSING INSPECTION is the one everyone does and many do too casually, because the house is clean, the finishes are new, and the eye slides over everything. This one covers what a resale inspection covers - roof, exterior, grading and drainage, attic, plumbing, electrical panel, HVAC operation, windows and doors, appliances, safety devices - plus the things unique to a first-time-occupied house, which is mostly about whether systems were finished and commissioned rather than merely installed.

Many buyers add a THIRD inspection near the end of the shortest warranty period, before the workmanship and finish coverage closes. It is a genuinely good idea: the house has been through a season, the trades have moved on, and a fresh professional eye produces a written list at exactly the moment the builder is still obliged to address it. That is the timing argument the new-build warranty guide makes at length.

What new houses actually get wrong

New construction defects have their own character, and it is not the character of an old house. They cluster in a few places.

WATER MANAGEMENT is first and most consequential: grading that slopes toward the structure, downspouts discharging against the foundation, flashing details at roof-to-wall junctions, window and door installation sequence, deck and balcony waterproofing. Water is what turns a small construction shortcut into an expensive claim years later, and it is the category where a pre-drywall look pays for itself.

SYSTEM COMMISSIONING is second. Modern homes carry more equipment than older ones - efficient HVAC, mechanical ventilation, tankless or heat-pump water heating, solar equipment, sometimes battery storage and controls. A great deal of that gear is installed correctly and then never properly commissioned: dampers left as found, ventilation not balanced, thermostats and controls left on defaults, systems never actually verified under load. Ask specifically whether commissioning was performed and whether the documentation exists.

INSULATION AND AIR SEALING is third, and it is invisible after drywall, which is precisely the point of looking earlier.

Then the ordinary trade misses: missing fire blocking, unsupported plumbing, an undersized or mislabelled electrical panel, doors and windows that bind, a bath fan venting into an attic instead of outdoors, safety devices absent or in the wrong locations. None of these is dramatic. All of them are cheaper to fix before drywall or before closing than after.

Hiring the right inspector, and using the report properly

Hire someone who inspects NEW construction regularly. The skill is different from resale work: the inspector is reading a house against plans and installation standards rather than reading the accumulated evidence of thirty years of ownership, and phase inspections require someone who can turn up on a construction schedule. Ask how many pre-drywall inspections they perform, ask to see a sample report, and confirm they carry appropriate insurance and can meet the builder's site requirements.

Hire them YOURSELF, and take the recommendation from someone whose interest aligns with yours rather than from the sales office. This is the same structural point the process guide makes about representation: the on-site sales agent works for the BUILDER, and a buyer is entitled to bring their own representation and their own inspector. That is a fact about how the transaction is arranged, not a criticism of anyone in it.

Then use the report the way it is meant to be used: as a WRITTEN LIST delivered to the builder, in the builder's own process, with dates and photographs. Distinguish for yourself between defects, incomplete work, and normal characteristics - a report that treats every observation as an emergency gets taken less seriously than one that separates them. And re-verify. Items marked complete are not complete until you or your inspector have looked.

Two Claremont notes to close. New homes here are mostly INFILL - a single home or a small project slotted into an established street - which means site work, drainage, and how the new grade relates to neighbouring properties deserve real attention, because they are the details that generate disputes with people you will live beside for years. And where the site is sloped, the soils, drainage, and retaining elements matter more than anything happening inside the house; a specialist look is money well spent.

This is general information. Your inspector, the builder's contract, and the City of Claremont's Building Division govern every specific - and permit and inspection requirements change, so the city counter is the authority.
