Home projects · Local approvals
A home project starts at the address, before the contractor calendar.
New York supplies the code frame, but the city, town, village, or county office usually runs permits and inspections. Define the work, find that office, check the property layers, and put the whole job in writing.
More property and permit paths
Reviewed July 12, 2026. Building codes, local permit lists, license rules, and filing systems change. The office serving the property controls the current answer.
The practical rule
A contractor's confidence is not a permit decision.
Confirm the scope, permit, and inspection list with the issuing office before demolition, deposits, or nonreturnable materials.
The useful order
Start with the exact address and scope.
Write down what will be removed, built, moved, wired, plumbed, heated, or used differently. Photos, dimensions, property lines, and a plain list of work make the first call useful. The local building or code office serving the address is normally the front door.
Check permit, zoning, and overlay rules before pricing the job.
A building permit is only one possible approval. Zoning, historic districts, flood areas, wetlands, shoreline rules, septic, wells, roads, utilities, co-op or condo boards, and New York City building records can affect the plan. Ask which approvals must come first.
Find out who may draw, file, and perform the work.
The scope may require a registered architect, professional engineer, licensed electrician, plumber, or locally licensed contractor. Home-improvement contractor licenses are required in New York City and in Nassau, Suffolk, Westchester, Putnam, and Rockland counties; other local licenses can also apply.
Compare contractors against the same written scope.
Get references, proof of insurance, license information where required, and more than one written estimate. New York law requires a written contract for covered home-improvement work. The contract should identify the work, materials, price, payment schedule, and timeline.
Tie payments to real progress.
Do not pay the full price at the start. Keep change orders in writing and make sure the payment schedule follows completed work and delivered materials. The Attorney General explains the escrow or bond rules that protect advance payments on covered jobs.
Make sure permits are issued before work starts.
Do not rely on 'we do this all the time.' Confirm the permit number, approved plans, contractor, and required inspections with the issuing office. Keep the permit and approved scope where both the owner and contractor can use them.
Close the job, not just the invoice.
Schedule every required inspection, resolve corrections, collect warranties and lien releases where appropriate, and obtain the final certificate, letter of completion, or other closeout record the office uses. Hold the final payment until the contracted work and required closeout are complete.
New York City uses DOB records and DOB NOW
Most City construction requires Department of Buildings approval and permits, although the City lists some minor work that may not need a work permit. The contractor can still need a Home Improvement Contractor license. Search the building record, check the permit question, and use DOB NOW for the current filing, permit, inspection, and closeout trail.
Old work can become part of the new job
An open permit, violation, missing certificate, unapproved apartment, or earlier alteration can change the route. Ask the office or design professional to read the existing record before the new scope is priced as if the property were clean.
Keep the closeout record with the house
Approved plans, inspection results, warranties, manuals, paid invoices, and the final municipal record belong in the property file. They can matter later for insurance, refinancing, a sale, or the next project.
