NYC Kitchen Remodeling — DOB Alt-2, Co-op Board Review, Wet-Over-Dry Rules

A kitchen remodel in New York City is not a kitchen remodel anywhere else. If you are in a co-op, you will sign an Alteration Agreement with your managing agent — Halstead, Douglas Elliman, FirstService, Rose Associates — before a single cabinet is demoed. If you are in a condo, your board bylaws will dictate insurance certificates, working hours, and whether you can touch the riser. If you are in a pre-1960 building, HPD will require XRF lead-paint testing before any dust-generating work. If you are in a pre-1987 building, DOB will require an ACP5 or ACP7 asbestos form on the filing. And if your plumbing moves more than 18 inches from its existing rough-in, you likely trigger a DOB Alt-2 filing with a licensed architect or PE — and in most co-ops, a wet-over-dry rule that blocks relocating plumbing over downstairs neighbors' living space.

AskBaily routes your NYC kitchen project to one vetted HIC- and DOB-licensed builder who has filed Alt-2s, negotiated Alteration Agreements, and survived co-op board interviews. Not twelve strangers who will blast-email your number for three weeks.

What a real NYC kitchen remodel involves

1. Board approval. Co-op boards review package, architect drawings, contractor insurance (typically $2M GL + workers' comp), and the Alteration Agreement itself. Expect 4-8 weeks.
2. DOB filing. Alt-2 if you're moving plumbing, gas, or mechanical. LAA Type 1/2/3 if mechanical-only. Needs RA/PE sign-off.
3. HPD prerequisites. ACP5/ACP7 asbestos, XRF lead-paint for pre-1960, occupant notification.
4. Actual construction. Typical 10-20 weeks depending on scope.

Frequently asked questions

Do I need a DOB permit to remodel my NYC kitchen? If you replace cabinets and appliances in place with no plumbing, gas, or electrical relocation, no. As soon as you move a sink more than a short distance, relocate a gas line, or add a dedicated circuit load beyond the panel's capacity, you are in Alt-2 territory and need a filed permit with architect or engineer sign-off.

What is a wet-over-dry rule? Most NYC co-op Alteration Agreements prohibit placing a new kitchen (wet) directly over a downstairs unit's bedroom or living room (dry). The rule protects against sound transmission and leak exposure. Exceptions exist for identical stacks.

How much does a NYC kitchen remodel cost? Mid-range finishes in a mid-size Manhattan co-op run $85K-$185K all-in. High-end brownstone and loft gut kitchens run $200K-$400K. Outer-borough 1-3 family work runs 30-50% less.
