When Is a DOB Permit Required?
The New York City Department of Buildings (DOB) requires a work permit for most roof-related construction activities. Unlike many suburban and rural jurisdictions in New York State where permitting requirements can be ambiguous, NYC's permitting framework is comprehensive and strictly enforced.
Permit Required
- Full roof tear-off and replacement
- Roof overlay (new material over existing)
- Structural repairs to rafters, joists, or trusses
- New skylight or rooftop hatch installation
- Parapet wall repair or modification
- Change of roofing material type (e.g., built-up to TPO)
- Rooftop mechanical equipment installation
- Green roof or solar panel installation
May Not Require a Permit (Ordinary Maintenance)
- Patching a small damaged area (under ~50 sq ft)
- Replacing a few individual shingles or tiles
- Re-sealing flashing or caulking joints
- Gutter cleaning and minor gutter repair
- Applying roof coating on an existing flat roof
Note: The DOB interprets "ordinary maintenance" narrowly. When in doubt, consult the DOB or your contractor.

Filing Pathways: Professional Certification vs Plan Exam
NYC offers two primary pathways for obtaining a roof replacement work permit. The pathway you use significantly affects the timeline, cost, and liability structure of the project. Your contractor and their design professional will recommend the appropriate pathway based on the project scope.
Professional Certification (PC)
Best for: Standard residential roof replacements, like-for-like material changes, no structural modifications
Requirements:
- NY State licensed architect or professional engineer files the application
- Design professional certifies code compliance
- All plans sealed and signed by the filing professional
- DOB NOW online filing with electronic plan upload
- No DOB plan examination required before permit issuance
Advantages
- • Fastest approval timeline
- • Most common pathway (~70% of residential roof permits)
- • Lower filing fees (no plan exam fee)
- • Straightforward process for experienced contractors
Disadvantages
- • Design professional assumes full legal liability for code compliance
- • Subject to DOB random audit after permit issuance
- • Non-compliance discovered during audit can result in permit revocation and professional discipline
- • Requires hiring a licensed architect or PE if the contractor does not have one on staff
DOB Plan Examination
Best for: Structural modifications, changes to roof slope or height, complex projects, buildings with open violations
Requirements:
- Full plan set submitted through DOB NOW
- DOB plan examiner reviews for code compliance
- Objection letters must be resolved before permit issuance
- May require multiple review cycles
- In-person appointments may be needed for complex objections
Advantages
- • DOB verifies code compliance before work begins
- • Lower liability risk for the design professional
- • Required for projects that include structural changes
- • Less audit risk since DOB reviewed plans upfront
Disadvantages
- • Significantly longer timeline
- • Higher fees (includes plan examination charges)
- • Potential for multiple objection rounds
- • Can delay project start by months in busy periods
DOB NOW Filing Process: Step by Step
All NYC DOB work permit applications for roof replacement are filed through the DOB NOW online portal. The following steps outline the complete process from pre-filing requirements through final sign-off. While your contractor or their expediter typically handles this process, understanding each step helps you monitor progress and hold your contractor accountable.
Pre-Filing: ACP-5 Asbestos Investigation
1 - 2 weeksBefore filing for a DOB work permit, the property owner must have an asbestos investigation conducted by a NYC DEP-certified asbestos investigator. The investigator collects samples of existing roofing materials and tests them for asbestos content. The results are documented on the ACP-5 form and filed with the NYC Department of Environmental Protection (DEP) through the DEP Asbestos Reporting System. This must be completed before the DOB application is submitted.
Engage Design Professional (if using PC pathway)
1 - 5 daysFor Professional Certification filings, engage a New York State licensed architect or professional engineer to review the project scope, prepare or review plans, and serve as the applicant of record. The design professional must hold current NYC DOB filing privileges. Many roofing contractors have relationships with filing architects who handle this step as part of the project.
Landmark Commission Review (if applicable)
2 - 6 weeks (if applicable)If the building is individually landmarked or located within a designated landmark district, submit an application to the NYC Landmarks Preservation Commission (LPC) for review before filing with the DOB. The LPC will review the proposed materials, color, and appearance of the new roof. Submit photos of the existing condition and material specifications for the proposed replacement. The LPC application can be submitted through the LPC Connect portal.
DOB NOW Application Filing
1 day (filing submission)File the work permit application through the DOB NOW portal (a]dobonline.nyc.gov). Upload all required documents including the scope of work, plans (sealed by the design professional for PC filings), ACP-5 filing confirmation, LPC approval (if applicable), contractor insurance certificates, and owner authorization. Pay the applicable filing fees online.
Permit Issuance & Pre-Work Requirements
1 - 3 days (PC) or 4 - 8 weeks (plan exam)Once approved (1-3 days for PC, 4-8 weeks for plan exam), download the permit from DOB NOW. The physical permit must be posted at the job site before work begins. Ensure all required insurance certificates are current. If the project involves scaffolding or sidewalk protection, a separate DOB filing may be required. Verify that the contractor pulling the permit is the contractor performing the work.
DOB Inspections & Sign-Off
1 - 4 weeks (after work completion)Schedule and pass required DOB inspections during and after the work. For PC filings, the design professional conducts progress inspections and provides a final sign-off letter (TR-1 form) certifying the work was completed in accordance with the approved plans. For plan exam filings, DOB inspectors conduct the inspections. The permit must be formally closed out with the DOB after work completion. Failure to close out permits creates open violations on the property record.
Hiring a Filing Expediter
Many NYC homeowners and contractors hire a professional filing expediter to handle the DOB NOW application process. Expediters specialize in navigating the DOB system, managing objections, and coordinating between the design professional, LPC, and DEP. Typical expediter fees range from $500 to $1,500 for a residential roof replacement permit. This is particularly worthwhile for landmark district properties and projects requiring plan examination, where the expediter's expertise can save weeks of delay. Your roofing contractor may include expediter services in their bid, or they may recommend a specific expediter they work with regularly.
Permit Costs & Fee Schedule
NYC DOB permit fees are based on the estimated cost of the construction work. The following breakdown covers all fees a typical residential roof replacement project may encounter. Your contractor should include permit costs in their proposal, and you should verify what is and is not included.
| Fee Type | Amount | Notes |
|---|---|---|
| DOB Filing Fee (under $25K) | ~$280 | Based on estimated construction cost |
| DOB Filing Fee ($25K - $50K) | ~$420 | Most common range for residential roofs |
| DOB Filing Fee ($50K+) | ~$560+ | Larger or complex projects |
| Plan Exam Fee (if not PC) | $280 - $500 | Waived for Professional Certification filings |
| ACP-5 Asbestos Investigation | $300 - $800 | Required for all renovation/demolition |
| LPC Review (landmark districts) | $200 - $1,000+ | Only if building is landmarked or in district |
| Filing Expediter (optional) | $500 - $1,500 | Professional permit filing service |
| Design Professional (PC filing) | $800 - $2,500 | Often included in contractor's bid |

ACP-5 Asbestos Investigation Requirements
New York City has some of the strictest asbestos regulations in the country. Before any demolition or renovation work that will disturb building materials, including roof replacement, the property owner must have an asbestos investigation conducted and the results filed with the NYC Department of Environmental Protection (DEP).
ACP-5 Process for Roof Replacement
Hire a certified investigator. The investigator must be certified by the NYC DEP as an asbestos investigator. They will collect bulk samples of all roofing materials that will be disturbed, including shingles, mastics, flashing compounds, insulation, and any underlying materials.
Laboratory analysis. Samples are sent to a certified laboratory for analysis. Results typically take 3-5 business days. Some labs offer 24-hour rush service for an additional fee.
File ACP-5 with DEP. The investigator completes the ACP-5 form documenting the findings and files it with the DEP through the Asbestos Reporting System. The filing generates a confirmation number needed for the DOB permit application.
If asbestos is found: A licensed asbestos abatement contractor must remove the asbestos-containing materials following DEP and EPA protocols before the roofing contractor can begin work. Abatement costs for a residential roof typically range from $3,000 to $15,000 depending on the extent of contamination.
Asbestos in roofing materials is most commonly found in homes built or re-roofed between the 1920s and 1980s. Common asbestos-containing roofing materials include certain shingle types, roof mastics and cements, flashing compounds, and pipe insulation in the attic space. Even if you believe your roof does not contain asbestos, the ACP-5 investigation is a legal requirement in NYC and cannot be skipped.
Failure to Comply
Commencing demolition or renovation without a filed ACP-5 is a violation of NYC Administrative Code Title 28 and DEP regulations. Penalties range from $2,500 to $10,000. If asbestos-containing materials are disturbed without proper abatement, additional DEP and federal EPA penalties apply, and the property owner faces potential criminal charges. The DOB will not issue a work permit without a filed ACP-5 confirmation number.
Landmark District Roof Requirements
New York City has over 150 designated landmark districts and more than 37,000 individually landmarked buildings. If your building falls under Landmarks Preservation Commission (LPC) jurisdiction, you must obtain LPC approval before filing for a DOB work permit. The LPC review adds time, cost, and material restrictions to your roof replacement project.
In-Kind Replacement
Replacing the roof with the same material and appearance (e.g., slate for slate, same color and profile). This is the simplest LPC approval pathway.
- • Certificate of No Effect (CNE) or Permit for Minor Work (PMW)
- • Staff-level review (no public hearing required)
- • Approval timeline: 2-4 weeks
- • Submit photos of existing condition + material specifications
Material or Appearance Change
Changing the roofing material (e.g., slate to architectural shingles) or altering the appearance of the roof (new dormers, skylights on visible elevations).
- • May require full Commission hearing
- • Public hearing with community board notice
- • Approval timeline: 4-8+ weeks
- • May be denied or require material upgrade

Jackson Heights
Ditmas Park
Prospect Lefferts Gardens
To check if your building is in a landmark district, use the LPC's online property search at the NYC LPC website or the DOB's BIS (Building Information System) which notes landmark status on the property profile. Your contractor should verify landmark status as part of their pre-project assessment. For NYC flat roof specifics, see our NYC flat roof replacement guide.
DOB Inspections & Permit Close-Out
Obtaining the permit is only the beginning. The DOB requires inspections during and after the work, and the permit must be formally closed out when the project is complete. Failure to close out a permit creates an open violation on your property record that can complicate future sales, refinancing, and permit applications.
Professional Certification (PC) Inspection Process
For PC filings, the design professional who filed the permit is responsible for conducting progress inspections. They must verify that the work conforms to the approved scope and complies with the NYC Building Code. Upon completion, the design professional files a final sign-off letter (TR-1 form) through DOB NOW certifying the work was completed as approved. The DOB may conduct random audits of PC sign-offs and will inspect the work if selected.
Plan Examination Inspection Process
For plan exam filings, DOB inspectors conduct the inspections. You or your contractor must schedule inspections through DOB NOW at required milestones. The final inspection verifies the completed work matches the approved plans. If the inspector identifies non-conforming work, corrections must be made and a re-inspection scheduled. The permit is closed out upon passing the final inspection.
Permit Close-Out Timeline
Permits should be closed out within 12 months of issuance. If work extends beyond this period, a permit renewal may be required. DOB permits that remain open beyond the allowed timeframe are flagged as "expired" and require additional filings to resolve. Your contractor is responsible for ensuring permit close-out, but as the property owner, you should verify this was completed by checking your property profile on BIS.
Penalty Schedule for Non-Compliance
NYC DOB enforces its permitting requirements aggressively. The following penalties apply to common violations related to roof replacement work. Remember that the property owner is often held liable for violations, even if the contractor is the one who failed to obtain proper permits.
Work without a permit
$10,000 - $25,000First offense for performing construction work without a required DOB permit. The property owner and/or the contractor may be cited. Additional penalties apply for each day work continues after a stop-work order is issued.
Failure to maintain permit at job site
$1,000 - $5,000The work permit must be posted in a visible location at the job site at all times during construction. Failure to have the permit available during a DOB inspection results in a violation.
Work not conforming to approved plans
$5,000 - $25,000Performing work that deviates from the approved scope, materials, or methods specified in the permit application. This includes using different roofing materials, changing structural details, or expanding the scope beyond what was permitted.
Failure to obtain LPC approval (landmark districts)
$5,000 - $15,000 (DOB) + LPC finesPerforming work on a landmarked building or in a landmark district without LPC approval. The LPC can impose separate fines and may require restoration of the building to its original condition at the owner's expense.
Failure to file ACP-5 (asbestos)
$2,500 - $10,000 (DEP)Commencing demolition or renovation without filing the required asbestos investigation report (ACP-5) with the NYC DEP. Additional penalties apply if asbestos-containing materials are disturbed without proper abatement procedures.
Failure to close out permit
Open violation on property recordNot filing the final sign-off (TR-1 or final inspection) after work is complete creates an open violation on the DOB property profile. This complicates future permit applications, property sales, and refinancing. Open violations may trigger DOB compliance inspections.
Stop-work order violation
$10,000 - $25,000 per dayContinuing work after a DOB stop-work order (SWO) has been issued. Each day of continued work constitutes a separate violation. Criminal charges may be filed for persistent violations.
Protect Yourself as a Property Owner
Always verify that your contractor has obtained the required DOB work permit before work begins. Ask for the DOB application number and check the status on DOB NOW or BIS. Include a contract clause requiring the contractor to obtain all necessary permits and close them out upon completion. Do not make the final payment until you have verified the permit has been signed off. For guidance on contractor selection, see our guide to choosing a roofer in New York.
Contractor vs Homeowner Permit Responsibility
In NYC, the division of responsibility for permits is different from many other jurisdictions. Understanding who is responsible for what protects you from liability and ensures the project runs smoothly.
Contractor Responsibilities
- Filing the work permit application through DOB NOW
- Engaging the design professional (architect or PE) for PC filings
- Posting the permit at the job site
- Scheduling and passing DOB inspections
- Closing out the permit upon completion (TR-1 filing)
- Maintaining valid insurance throughout the project
Homeowner Responsibilities
- Arranging and paying for the ACP-5 asbestos investigation
- Signing the owner authorization on the DOB application
- Verifying the permit was issued before work begins
- Checking BIS after completion to confirm permit close-out
- Applying for LPC review if in a landmark district (often delegated to contractor)
- Retaining all permit documentation for property records
Your roofing contract should clearly specify who is responsible for permit acquisition, associated costs, and close-out. For a complete contract checklist, see our roofing contract checklist.
