It’s a common assumption among new-construction buyers: if it’s brand new, it must be fine. New houses don’t need inspections. That’s one of the most expensive mistakes a Long Island buyer can make.
New construction is not the same as defect-free construction. Builders work fast. Subcontractors are rushing between jobs. Inspections happen at each phase of construction, but municipal inspectors are checking for code compliance — not the level of craftsmanship or workmanship quality that a licensed home inspector evaluates.
What a New Construction Inspection Covers
A home inspector looks at the completed home as a system — not individual trade sign-offs. The most common issues found in brand-new Long Island homes include:
- Improperly sealed or missing insulation in attic and crawlspace
- HVAC systems not balanced or tested at full load
- Grading and drainage issues around the foundation
- Missing caulk or improper flashing around windows and doors
- Electrical panel issues — breakers not labeled, improper grounds
- Plumbing rough-in errors that passed inspection but cause future problems
- Drywall cracks and nail pops — sometimes cosmetic, sometimes structural
On Long Island, we’ve found water intrusion in homes less than 6 months old. Attic insulation installed incorrectly. Sump pump discharge lines that don’t drain far enough from the foundation. These aren’t rare — they’re patterns we see consistently in new builds across Nassau and Suffolk counties.
The Pre-Drywall Inspection Option
If you’re buying a home that hasn’t been completed yet, a pre-drywall inspection is your best opportunity to see what’s inside the walls before they’re closed up. This is when framing, plumbing rough-ins, electrical wiring, and HVAC ductwork are all exposed. Problems caught at this stage are easy and cheap to fix. Problems found five years later are not.
Most builders will allow a pre-drywall inspection. Some require 48 hours notice. Your real estate agent should request access in writing during the negotiation phase of your purchase.
Certificate of Occupancy ≠ Inspected and Approved
The certificate of occupancy means the local municipality has determined the home meets minimum code requirements. It does not mean every system was tested, that workmanship is excellent, or that there are no defects. A CO is a baseline — not a guarantee.
Builders typically offer a one-year builder’s warranty. To take full advantage of it, get your home inspected within the first 10 months. Give yourself time to document every issue before the warranty expires. Many builders are responsive when problems are caught early and documented properly.
The Inspection Boys has inspected hundreds of new-construction homes across Long Island. Our inspectors know what to look for and how to document issues clearly enough to hold builders accountable. Call us at (516) 591-3262 or book online today.
