An inspection is cheap.
Skipping one rarely is

A few hundred dollars buys the only independent read on the building you will get before you are committed. In New York the window for it is short and easy to miss.

Before you read on

  • Inspection practice differs by state. New York custom is described here; in escrow states the inspection sits inside a contractual contingency period.
  • An inspector reports on condition. They do not value the property and do not advise on whether to buy.

Step 1Where the inspection sits in a New York purchase

Not after contracts, as buyers from other states expect. Before them, in the days between an accepted offer and signature.

New York contracts are typically signed “as is”, with no inspection contingency written into them. Once you have signed and wired the deposit, a defect found later is your defect. The leverage exists only in the two to three week window before signature, which is why the inspection has to be booked the day the offer is accepted rather than the week the attorney finishes reviewing.

Property typeIs an inspection usualWhy
House, townhouse, brownstoneAlwaysYou own the roof, the boiler, the façade and the plumbing outright
Small multifamilyAlways, plus a roof and boiler specialistSystems are older and shared, and the cost of replacement is six figures
CondominiumOften, and worth itThe unit is yours; the building's problems arrive as assessments
Co-opLess common, still sensibleBoard packages and minutes matter more, but the unit's own plumbing still leaks
New developmentYes, before the walk-through sign-offPunch lists are settled at the walk-through, and after that they are goodwill

Step 2What a general inspection covers

Structure and exterior
SHELL

Foundation, framing where visible, façade, roof covering and drainage, windows, grading around the building. Cracking patterns matter more than cracks.

Systems
MECHANICAL

Heating and cooling, water heater, main electrical panel and its capacity, visible wiring, supply and waste plumbing, water pressure. Ages and remaining life are estimated for each.

Interior
FABRIC

Floors, ceilings, stairs, doors, and evidence of past water. Stains, patched ceilings and fresh paint on one wall are read as history, not decoration.

Moisture and mould
WATER

The single most common finding, and the most expensive to ignore. Basements, the underside of bathrooms, and anything below a roof terrace.

Step 3What a general inspection excludes, and what to add

Add-onTypical costWhen it is worth it
General inspection$400–$1,200Always, priced by square footage
Sewer lateral camera$300–$700Any house over fifty years old, and every brownstone
Radon test$150–$300Houses with basements outside the city core
Lead paint assessment$300–$600Anything built before 1978, especially with children
Asbestos sampling$200–$800Pre-1980 buildings with original pipe insulation or floor tile
Termite and pest$100–$300Wood frame construction and anything with a crawl space
Oil tank sweep$150–$400Suburban houses converted from oil, where an abandoned tank is a liability
Engineer's structural report$1,000–$3,000Visible movement, or before buying a whole building

Step 4Using the report without losing the deal

A report of forty pages will contain forty findings, because that is what inspectors are paid to produce. The mistake buyers make is to send the whole document to the seller and ask for everything. It reads as a renegotiation of the price on a technicality, and in a market with other bidders it ends the conversation.

Separate the findings into three groups: safety and structure, systems at the end of their life, and cosmetics. Raise the first two, with a contractor’s number attached to each, and let the third go. A specific request for a $14,000 boiler is answerable. A request for “a credit for the repairs” is not.

FindingReasonable askUsual outcome
Active leak, standing water, structural movementRepair before closing, or a credit at costSeller repairs or the deal ends
Boiler or roof at end of lifePrice reduction of part of the replacement costSplit, more often than not
Outdated panel, knob-and-tube wiringCredit toward an electrician's quoteNegotiated, since insurers may require it anyway
Missing handrails, no smoke alarmsSeller corrects before closingAlmost always agreed; it is cheap
Worn finishes, tired kitchenNothingPriced in already
Can I attend?

Yes, and you should. Two hours walking the property with an inspector teaches you more about the building than any report, and questions asked in person get fuller answers than an email a week later.

Who chooses the inspector?

You do, and it should not be someone the listing agent recommends. Ask for a sample report before booking — the quality varies enormously.

Is an inspection possible in a bidding situation?

Yes, but it has to be fast. Book for within seventy-two hours of acceptance, and tell the listing agent when it will happen so the delay is visible and short.

Do I inspect a co-op?

The unit, yes, if there is any history of leaks. Beyond that, the building's financial statements, the last two years of board minutes and the reserve balance tell you more than an inspector can.

What about new construction?

Inspect it. New buildings fail on workmanship rather than age — window seals, waterproofing at terraces, and mechanical systems commissioned in a hurry.

Let’s talk first

Tell us what you are under offer on and we will arrange the inspection, read the report with you, and tell you which findings are worth raising.
