The NYC As-Is Reality
Most NYC co-op and condo purchases include "as-is" language in the contract, and many buildings have limited seller disclosure relative to what a typical suburban home sale would require. Buyers cannot rely on disclosure — they must investigate.
The window for investigation is typically attorney review, before the buyer signs the contract. An inspection contingency giving the buyer the right to withdraw based on inspection findings is relatively rare in competitive NYC markets — most buyers conduct inspections quickly and negotiate specific issues rather than using inspection findings as a general escape clause.
This means inspections need to happen fast — typically within 5–10 days of accepting a deal, before contract signing.
The Checklist: What to Order and When
Pre-Contract (Before Signing)
1. General Building Inspection
Who needs it: Everyone. Even in an as-is sale, a licensed building inspection establishes what conditions exist before you're legally bound.
What it covers: Structural components visible in the unit, electrical panel, plumbing, HVAC, windows, doors, walls, ceilings, floors.
Limitation in co-ops: Inspectors typically cannot access mechanical rooms or common areas controlled by the co-op board. You're inspecting the unit only.
2. Mold Inspection
Who needs it: Any property with a history of water damage, visible moisture staining, musty odor, or previous flooding. Properties with poorly maintained bathrooms or kitchens. Pre-war buildings where water intrusion is common.
What it covers: Visual assessment of all accessible areas, air sampling, laboratory analysis, written report.
How it fits: Mold findings can support a price renegotiation or, in severe cases, contract cancellation if made a contingency.
3. Asbestos Inspection
Who needs it: Buyers planning immediate renovation in pre-1987 buildings. If you're buying and immediately planning a gut renovation, an asbestos survey should be done before contract signing — asbestos abatement adds significant cost and delay to renovation projects.
What it covers: Survey of all suspect ACMs in the unit; laboratory PLM analysis.
Note: Co-op boards typically control asbestos in common areas; the unit survey covers your space only.
Pre-Contract or Post-Contract (Depending on Urgency)
4. Lead Paint Inspection
Who needs it: Buyers with children under 6 in any pre-1978 building. Buyers planning renovation in pre-1978 buildings (renovation creates exposure risk). Buyers evaluating NYC Local Law 31 compliance status of the building.
What it covers: XRF testing of all painted surfaces in the unit.
Note: Ask the building management what the building's Local Law 31 compliance status is before ordering — if the building has already completed XRF testing, you may be able to review existing results.
5. Radon Testing
Who needs it: Ground-floor and first-floor units in low-rise buildings (under 3 stories); townhouses and rowhouses; any unit with a basement or below-grade space.
Not relevant: High-rise apartments above the third floor.
Protocol note: Requires closed-building conditions for 48–96 hours — coordinate with sellers or management for access.
Building-Level Due Diligence
For co-op purchases especially, environmental due diligence extends beyond the unit:
Review the building's environmental history:

Timing Advice
Order environmental inspections in this sequence:
1. Building inspection first — establishes baseline conditions and identifies visible issues to follow up on
2. Mold and asbestos concurrent — if building inspection reveals water damage or the building is pre-1987, order mold and asbestos simultaneously to save time
3. Lead paint — can follow mold/asbestos; typically lower urgency unless children are present
4. Radon — if applicable; requires access for 48–96 hours
The total elapsed time for all inspections, including laboratory turnaround, is typically 5–8 business days when coordinated well. Book inspections immediately after your deal is accepted.
