- Simple NYC filings take weeks and complex filings take months; the DOB queue is only one part of the clock.
- Board approval, drawings and objection responses often take more calendar time than the city's review itself.
- Landmarked buildings often add about 15 to 20 percent to time and budget.
- A full apartment gut renovation typically takes four to nine months including approvals.
- Start the paperwork before you order materials, and confirm current DOB processing at the source.
Everyone wants the same thing from a permit: a date. When can we start? When will the kitchen be done? Will the new bathroom be ready before the in-laws arrive? The honest answer in New York is that the permit is rarely a single date. It is a chain of steps owned by different people, and the time it takes is the sum of the slowest links.
This guide breaks the chain down. It explains what happens between "we want to renovate" and "work can begin," how long each stage commonly takes in broad terms, what stretches the schedule, how timelines differ for a repaint, a bathroom, a kitchen and a full gut, and what Long Island and New Jersey look like by comparison. Everything here is planning guidance as of October 2026, not a promise, because the Department of Buildings and your own board control much of the calendar.
1. The Honest Answer: Weeks for Simple, Months for Complex
There is no single number, and anyone who quotes one without asking about your building is guessing. As a framework:
- Simple filings with straightforward scope and clean documents can move in weeks.
- Complex filings, such as structural changes, changes of use, multiple trades or repeated objections, can take months.
- Landmarked buildings often add about 15 to 20 percent to time and budget.
- Co-op and condo approvals often precede the filing and may take weeks, since many boards meet monthly.
- Full apartment gut renovations typically run four to nine months including approvals.
The Department of Buildings explains the permit process on its how to obtain a permit page and posts procedure changes on its service updates page. Because processing times change, check those pages and ask your design professional for current experience.
One more distinction matters. "How long does the permit take" can mean the city's review, or it can mean the whole period from deciding to renovate until the first hammer swing. Homeowners usually care about the second. We use that definition below.
2. Stage by Stage: Where the Time Goes
A typical alteration moves through these stages. Durations are broad planning ranges, not guarantees.
| Stage | What happens | Who controls the clock | Typical time |
|---|---|---|---|
| 1. Scope and budget | Decide what you are building and what it may cost | You and your contractor | Days to a few weeks |
| 2. Hire design professional | Select the architect or engineer who will be Applicant of Record | You | Days to weeks |
| 3. Measure and draw | Survey existing conditions and prepare plans | Design professional | Often several weeks |
| 4. Board package and approval | Alteration agreement, insurance, plans, board meeting | Board and managing agent | Weeks; depends on meeting schedule |
| 5. Landmarks review, if applicable | LPC approval for regulated work | LPC | Weeks to months, depending on permit type |
| 6. DOB filing and plan review | Submission, reviewer comments | DOB | Weeks for simple, months for complex |
| 7. Objections and revisions | Responding to plan examiner comments | Design professional | Days per round, often more than one round |
| 8. Permit issuance | Fees, contractor details, insurance, trade permits | Applicant, contractor, DOB | Days to a couple of weeks |
| 9. Construction | The actual work | Contractor | Weeks to months |
| 10. Inspections and sign-offs | Rough-in and final inspections | DOB, trades | Staged through construction |
Stages 3 through 5 are where homeowners lose the most time without noticing, because they happen before anyone files anything. Calendars are often slowed less by the DOB than by unsettled scope: changing the kitchen layout after the drawings are done restarts the clock.
3. Example Timelines by Project Type
These examples show how the pieces combine. They are illustrative planning ranges as of October 2026, not quotes or promises, and a written schedule from your contractor governs.
Interior painting
Generally no DOB permit. Co-op or condo notice and insurance may take days to a couple of weeks. Painting takes about 2 to 7 working days for a one- to three-bedroom apartment. See our guide to how long it takes to paint an NYC apartment.
Flooring replacement
Usually no DOB permit for like-for-like finish flooring, but board rules apply. Installation of hardwood takes about 3 to 7 days plus finish cure. Add time for approvals and acoustic specifications.
Bathroom tile only
If plumbing does not move, there is typically no DOB permit. Tile in one bathroom takes about 1 to 2 weeks including waterproofing cure. Our bathroom tile timeline and our explanation of how long grout takes to dry cover the cure and wait times that no schedule can skip.
Bathroom renovation with plumbing changes
Expect drawings, board approval and a DOB filing before construction. Construction typically takes 3 to 6 weeks after permits are issued. Overall, many owners should plan for a few months from first call to finished bath.
Kitchen renovation
Construction commonly runs 6 to 12 weeks. With drawings, board approval, filing and long-lead cabinetry, a total of several months is common.
Full apartment gut
Typically 4 to 9 months including approvals. Landmarked buildings and complex structural scope can push it longer.
4. What Slows Permits Down
Delays follow patterns. The common ones:
- Scope that keeps changing. Each revision means new drawings and sometimes a new review round.
- Incomplete documents. Missing certificates, signatures or ownership details return applications.
- Board meeting calendars. A missed deadline can add a month.
- Slow responses to objections. Plan examiner comments that sit unanswered add time one for one.
- Hidden conditions. Opening walls reveals asbestos, rot or non-conforming work, which changes scope and sometimes the filing.
- Landmarks complexity. Visible changes require careful drawings and sometimes multiple meetings.
- Contractor paperwork. Missing licenses, registrations or insurance certificates delay permit issuance. Residential remodeling in NYC requires a Home Improvement Contractor license from the Department of Consumer and Worker Protection.
- Hazmat. Pre-1987 buildings commonly need asbestos surveys before disturbing suspect materials, and pre-1978 buildings require lead-safe practices.
- Seasonal bunching. Spring and fall are busy for design professionals, trades and boards.
You cannot control the DOB's queue, but you control the rest. Decide scope early, give your design team what they need quickly and respond to objections fast.
5. How to Shorten the Timeline (Legitimately)
Honest strategies that work:
- Freeze the scope before drawings. Make layout decisions first, finishes later.
- Begin the board process at the same time as design. Many boards want preliminary drawings, and early conversations with the managing agent reveal timing and requirements.
- Hire an experienced team. A design professional and contractor who file regularly in your building type avoid avoidable objections.
- Prepare a complete package. Ownership documents, certificates of occupancy, insurance certificates and board forms ready at filing.
- Answer objections within days. Keep one person responsible for tracking them.
- Plan construction around lead times. Order cabinetry, windows and specialty tile when the scope is final.
- Bundle work. Doing kitchen and bath together under one filing can be more efficient than two separate projects.
- Avoid shortcuts. Skipping permits can lead to stop-work orders, fines, insurance denial and resale problems. They are rarely faster in the end.

6. Landmarks, Co-ops and Other Add-Ons
Several overlays add time beyond the DOB.
Landmarks. Work on landmarked buildings and in historic districts may require Landmarks Preservation Commission approval before DOB issues certain permits. The LPC's permit types are Certificate of No Effect, Permit for Minor Work and Certificate of Appropriateness. Simpler permit types move faster than those requiring public hearings. See the LPC permit applications page for process details, and plan on about 15 to 20 percent added time and budget for landmarked buildings.
Co-ops and condos. Boards set their own approval timelines, often monthly. Industry reports state DOB reinstated, effective January 26, 2026, a board-approval attestation inside DOB NOW: Build; confirm with the DOB and your managing agent. Either way, the practical advice is to secure board approval before you file.
Hazmat. Asbestos surveys and abatement, when required, add time before demolition.
New code coming. Local Law 33 of 2026 enacts a new NYC Existing Building Code that DOB says takes effect July 17, 2027 and will govern all alteration applications. Until then current rules apply. If your project may span that date, ask your architect how filing timing could matter.
Sidewalk sheds and scaffolding. For exterior work, sidewalk shed rules changed on August 13, 2026, so check requirements early if your project needs access equipment.
7. Cost of Time: What Delays Do to Your Budget
Time is money in a renovation. Delays can mean extra rent or carrying costs, price changes on materials, storage fees, and contractor rescheduling. As typical 2026 planning guidance, design, engineering, expediting and permit fees often add roughly 15 to 25 percent over construction cost, and complex filings with repeated objections lean to the higher end. A written itemized quote governs, and our guide to what a renovation costs in NYC in 2026 puts those numbers in context.
If you are living elsewhere during construction, ask for a schedule that separates approval time from construction time. The first is mostly out of anyone's hands, the second is where a contractor's planning shows. The renovation ROI calculator can also help you decide whether a larger scope that requires more approvals is worth the extra months.
8. Why a Design-Build Contractor Shortens the Real Timeline
N.Y. Renovation Services approaches this work as an in-house design-build contractor, which shapes everything that follows.
Permits do not build themselves, but the way your team is organized affects how fast you get from idea to start date. A design-build contractor removes the handoffs where time leaks.
One team writes scope, schedule and price. When the people drawing, pricing and building work together, scope decisions get made once. That avoids the redraws that cost weeks.
Board packages assembled early. We prepare alteration agreements, insurance certificates, schedules and scopes your managing agent expects, and we track the approval calendar so a missing form does not cost a month.
Coordination with the Applicant of Record. We work with registered architects and licensed engineers, so drawings, filing and construction scope stay aligned, and objections get answered quickly.
Honest dates. We separate approval time from construction time in our schedules, and we tell you what we control and what we do not. If a board or agency pushes a date, you hear from us first.
Trades booked around approvals. We line up tile, flooring, painting and trade crews to start when permits and inspections allow, rather than hoping a crew can be found the week your permit issues.
Fewer surprises at the start line. Because we review your building's rules, age and likely hazmat questions at the estimate stage, we can often tell you early whether you are looking at a straightforward filing or one that will need surveys, landmarks review or extra board steps. That early read does not remove the wait, but it lets you plan housing, deliveries and budget around a range you can trust.
Transparent pricing. Written quotes list design and filing, demolition, construction, allowances and cleanup separately, with no hidden fees. N.Y. Renovation Services is fully licensed and insured, and five percent of total project cost is donated to a nonprofit of the client's choice.

9. Long Island and New Jersey
The DOB governs only New York City. Elsewhere:
Long Island. Building permits come from the town, village or city building department, such as Hempstead, Oyster Bay, Garden City or Huntington. Nassau and Suffolk counties require home improvement contractor licensing through county consumer affairs. Residential permits for simple work often move faster than complex NYC alterations, but timing depends on the office and the season.
New Jersey. Permits are issued by the local municipal construction office under the Uniform Construction Code, administered by the NJ DCA Division of Codes and Standards. Review is split into subcodes such as building, electrical and plumbing, each with its own technical review. NJ also requires Home Improvement Contractor registration with the Division of Consumer Affairs.
Flood zones. In FEMA flood zones on Long Island, Queens, Staten Island and Brooklyn, elevation and flood-resistant materials rules may affect permit review for larger improvements. Verify with the DOB or your municipality.
10. Neighborhoods and ZIP Codes We Serve
N.Y. Renovation Services works across all of the areas below, and local building stock, board culture and municipal rules change how we scope each job.
Permit timing is shaped by building type and local rules. Here is how we think about the places we work:
- Inwood, Manhattan (10034, 10040): pre-war apartment buildings and older co-ops, where board calendars and building age (and the hazmat surveys that come with it) set the pace.
- Bay Ridge, Brooklyn (11209, 11220): brick row houses, co-ops and detached homes. Co-op approvals and plumbing-stack questions drive timing; see our Bay Ridge luxury apartment renovations page.
- Jamaica, Queens (11432, 11433, 11435): multifamily buildings, co-ops and mixed-use properties, where multiple-dwelling rules and mixed occupancy can add review steps.
- Westerleigh, Staten Island (10314): detached homes on large lots, where simple residential filings are the norm and site conditions matter more than board calendars.
- Hicksville, Nassau County (11801): capes and ranches in the Town of Oyster Bay, where the town building department handles permits rather than the DOB.
- Millburn, New Jersey (07041): large colonials and downtown condos, where the municipal construction office and subcode reviews set the timeline.
Our kitchen remodeling page shows how we sequence permits and construction on one of the most common permitted projects.
