- Permit work runs in phases: scope, professional, hazmat testing, board approval, filing, construction and closeout.
- A registered architect or licensed engineer must file most alteration applications as applicant of record.
- Buildings of certain ages commonly require asbestos surveys before demolition; certified abatement follows if asbestos is present.
- Landmarked buildings add Landmarks Preservation Commission review and often 15 to 20 percent more time and budget.
- Close out the permit; open permits and missing sign-offs surface later in sales and refinancing.
A permit is not one form. It is a chain of decisions, tests and approvals that begins before the first drawing and ends after the last tile is grouted. Most guides cover the middle of that chain, the filing. This one follows the whole thing, so you know what comes before, what comes after and what can go wrong between.
If you want the short version that covers the core steps, our companion article on getting a building permit for an NYC renovation is the quicker read. This page is the complete guide. It is current as of October 2026.
1. Phase Zero: Define What You Are Actually Doing
Permit questions are scope questions. Before anyone files anything, write down what changes:
- Which rooms and floors are affected?
- Do walls, doors, windows or stairs move?
- Do plumbing, gas or electrical lines move, grow or get replaced?
- Is the work structural, mechanical or purely cosmetic?
- Does the use of the space change?
- Will the exterior change, such as facade, windows or stoop?
Cosmetic work such as painting generally does not need a DOB permit. Layout changes, kitchen and bath renovations with plumbing changes, structural openings and mechanical systems usually do. In landmarked buildings, even some cosmetic exterior work needs a Landmarks permit. If you are unsure, our guides on when you need a building permit in New York and whether you need an NYC renovation permit go through common cases.
2. Phase One: Hire the Professional Who Will File
Alteration applications are filed through DOB NOW: Build by a New York State registered architect or licensed professional engineer, who serves as applicant of record. They certify that the drawings comply with the code.
DOB application types include New Building (NB), Alteration-CO for changes that affect use, egress or occupancy, and Alteration for other work. You may still hear the older Alt1 and Alt2 labels. Permit renewals and some filings remain in legacy systems.
Residential remodeling contractors in NYC must hold a Home Improvement Contractor license from the Department of Consumer and Worker Protection. The DOB's guide to obtaining a permit outlines how licensed professionals fit into the process. Electrical work has its own track; see our NYC electrical permit guide.
3. Phase Two: Existing Conditions and Hazmat Testing
Good drawings start with accurate existing conditions. A measured survey records walls, openings, ceiling heights, risers and structure. In older buildings, you also need to know what the walls and floors contain.
Asbestos
Asbestos was widely used in building materials until late in the twentieth century. It can appear in floor tile and mastic, pipe and boiler insulation, plaster, joint compound and roofing. It is harmless when undisturbed and dangerous when airborne. Disturbance of suspect asbestos-containing materials in older buildings requires an asbestos survey or assessment and, when asbestos is present, certified abatement. NYC DEP and DOB oversee this, and buildings built before 1987 commonly trigger surveys.
The EPA's asbestos page explains the hazard in general, and the NYC Department of Environmental Protection covers local requirements. No honest contractor promises a building has no asbestos before it is tested.
Lead
If painted surfaces will be disturbed in pre-1978 homes, the EPA Renovation, Repair and Painting rule requires certified firms and lead-safe work practices. New York City has its own lead rules for older buildings, especially those built before 1960.
Silica
Cutting and demolishing concrete, masonry and tile creates respirable crystalline silica dust. OSHA's standard requires dust control and respirators where needed. Good contractors build that into their plan from the start.
4. Phase Three: Board and Landlord Approvals
Co-ops and condos require approval before work begins.
- Review the alteration agreement. It defines forms, fees, deposits, insurance and work hours.
- Assemble the package. Drawings, scope narrative, contractor license and insurance, schedule and sometimes engineering letters.
- Respond to board comments. Engineers hired by the board often request revisions.
- Obtain written approval. Some boards also require a pre-construction meeting.
- Reserve elevators and loading access. Many buildings require reservations well in advance.
Industry reports indicate DOB reinstated a board attestation inside DOB NOW: Build effective January 26, 2026, confirming alterations are board-approved. Confirm with DOB and your managing agent. Either way, expect to show board approval.
Rental tenants should coordinate with their landlord. Owners of multiple dwellings also face repainting requirements; the Housing Maintenance Code requires apartments to be repainted every three years and between tenancies, and NYC's housing agency enforces it.
5. Phase Four: Landmarks Review, If It Applies
Landmarked buildings and buildings in historic districts need Landmarks Preservation Commission approval for exterior changes and, in some cases, interior ones. The LPC issues three kinds of permits: a Certificate of No Effect, a Permit for Minor Work and a Certificate of Appropriateness. The right one depends on how visible and significant the proposed change is. See the LPC's permit application page.
Landmark review often adds roughly 15 to 20 percent to time and budget. It also needs accurate drawings and photographs of existing conditions. Start it early, because DOB may not issue a permit for exterior work without it.
6. Phase Five: Filing, Review and Objections
Your design professional files in DOB NOW: Build. DOB checks the application against zoning, the construction codes and fire and safety rules. Responses may include approval, objections that require revised drawings, or requests for documents.
Tips that reduce friction:
- Make drawings consistent across sheets.
- Include product data and equipment specifications where required.
- Respond to objections quickly and completely.
- Do not start work before the permit is issued.
- Track every filing and permit number in one file.
DOB posts service updates regularly and procedures change, so check before you file.
Looking ahead: new codes
Local Law 33 of 2026 enacts a new NYC Existing Building Code that replaces the 1968 code for alterations. DOB says it takes effect July 17, 2027 and will govern all alteration applications. Until then, current rules apply. Other recent changes include Local Law 47 of 2026, which aligns the city energy code with the state code, Local Law 102 of 2025, which requires residential gas detectors near gas-fed appliances beginning January 1, 2027, and new sidewalk shed rules that took effect August 13, 2026. DOB began accepting cellar ADU applications for one- and two-family homes in April 2026.
7. Phase Six: Construction, Inspections and Compliance
When the permit is issued, work can begin within its limits.
- Keep documents on site. The permit and approved plans should be available.
- Follow the schedule. Noise Code hours generally run weekdays from about 7 AM to 6 PM unless an after-hours variance is approved, and many co-ops and condos restrict work to roughly 9 AM to 5 PM on weekdays.
- Use licensed trades. Plumbing and electrical work require licensed professionals.
- Schedule inspections. Some stages, such as rough plumbing or electrical, require inspection before walls close.
- Control changes. If scope changes, tell your professional so the filing and the board record stay accurate.
Change orders and open permits are a common source of friction later. Document every change in writing.
8. Phase Seven: Closeout and Sign-Off
The permit is not finished when the paint dries. Closeout includes final inspections, sign-off of completed work by your professional, any required certificates and closing the permit with DOB. For some jobs, a Letter of Completion or an updated certificate of occupancy is part of the record. Your professional tells you which.
Why it matters: open permits, missing sign-offs and unresolved violations show up when you sell, refinance or file insurance claims. A buyer's attorney or lender may require closure. Ask your contractor to include closeout in the scope and price. Our guide on navigating NYC permits for renovation covers common closeout mistakes, and the 2026 update of NYC renovation permits tracks code changes.

10. Why a Design-Build Firm Is Your Best Ally
Every phase above has a handoff. Surveyor to architect. Architect to board. Board to DOB. DOB to contractor. Contractor to inspector. Each handoff is a place where scope drifts and schedules slip. A hypothetical example shows how: the board approves a plan with a certain flooring underlayment, the contractor swaps it for a cheaper one to save time, and the final inspection or the board's engineer flags the mismatch. The fix costs more than the original.
N.Y. Renovation Services designs and builds in-house, from blueprints to the final coat of paint, so those handoffs sit inside one team. We are fully licensed and insured. We handle permitting and co-op or condo board paperwork when your project requires it, work with registered design professionals, arrange asbestos and lead testing in older buildings, coordinate licensed plumbing and electrical trades, and plan around freight elevators and building hours. We price in clear line items: design, filing, testing, demolition, construction and finishes. Five percent of total project cost goes to a nonprofit you choose.
For you, the practical benefits are fewer surprises and one accountable contact. We include approvals in the schedule instead of treating them as someone else's problem, and we include closeout in the scope so open permits do not follow you later.
Consider what the alternative looks like. Many homeowners hire a contractor first and discover mid-project that a filing, a board package or a hazmat survey was missed. Work stops, crews leave for other jobs and deposits are tied up while paperwork catches up. Others hire a drafter who produces drawings no contractor has priced, and the budget collapses at bid. A design-build approach prices while it designs, so the drawings match what can be built and what the board approved.
We also protect your calendar. Our schedules show approvals, testing, demolition, rough-in, inspections, tile, flooring and paint as linked steps, with the dependencies visible. If the board needs three weeks, the schedule says so, and the crews are booked after it, not before. When a building's rules limit hours, we sequence loud work inside the allowed window and keep the quiet work for the rest. You can ask for a permit-ready scope and price before you commit to anything.
Our focus areas are full gut renovation, tile, flooring, interior painting and exterior painting, plus kitchens and baths that use them. Start with Kitchen Remodeling NYC or request an itemized quote for the whole job.
11. Neighborhoods and ZIP Codes We Serve
Permit paths vary by building and municipality.
- Lower East Side, Manhattan (ZIP 10002): Tenements, mixed new condos and walk-ups with narrow stairs. Older stock raises hazmat testing, and tight access shapes demolition and delivery plans.
- Bushwick, Brooklyn (ZIPs 11206, 11221, 11237): Brick row houses, converted lofts and two- to four-family buildings. Multifamily layouts and loft conversions often involve egress and occupancy questions.
- Richmond Hill, Queens (ZIPs 11418, 11419): Victorian wood-frame homes and two-family houses, where framing, older wiring and lead paint come up often.
- Annadale, Staten Island (ZIP 10312): Detached homes and townhouse complexes. Association rules and DOB filings apply for structural work.
- Cedarhurst, Nassau County (ZIP 11516): Five Towns large colonials. Permits come from the local building department, and county contractor licensing applies. Verify with the municipality.
- Tenafly, Bergen County NJ (ZIP 07670): Colonials on large lots. Permits are issued by the local municipal construction office under New Jersey's Uniform Construction Code, and contractors must register with NJ Consumer Affairs.
