Planning a kitchen remodel in Mott Haven? Finishing a basement in Riverdale? Adding a bathroom in Fordham? Before your contractor lifts a single hammer in 2026, you need to understand Bronx home renovation permits — what they are, when you need them, how much they cost, and what happens if you skip them.
The NYC Department of Buildings (DOB) enforces the building code across all five boroughs, including the Bronx. Moreover, getting a permit is not just bureaucratic red tape — it protects your investment, keeps your property insurable, and ensures the work meets safety code. If you skip a permit, you face fines, stop-work orders, and serious complications when you try to sell or refinance.
This complete 2026 guide — brought to you by Brilliant Renovation LLC, a licensed contractor serving the Bronx and Westchester County for over 12 years — covers every permit type, current fees, step-by-step filing instructions, 2026 rule changes, and honest answers to the questions homeowners ask us most.
What Are Bronx Home Renovation Permits?
The Basic Definition
A renovation permit is official written authorization from the NYC Department of Buildings (DOB) that allows you to perform construction, alteration, demolition, or repair work on a property legally. According to the NYC DOB, the majority of construction work requires a permit. Furthermore, every permit issued ensures your proposed work complies with the NYC Building Code, the NYC Zoning Resolution, and all applicable safety standards.
The legal authority for NYC building permits comes from NYC Administrative Code Title 28 and the NYC Building Code 2022. The NYC DOB issues and enforces all permits, and it operates a borough office directly in the Bronx to serve local homeowners.
How Big Is the NYC Permit System?
The DOB processes an enormous volume of applications citywide. In 2024 alone, the DOB processed over 285,000 permit applications across New York City. Because the volume is so high, the DOB takes violations seriously. Working without a proper permit can result in Work Without Permit (WWP) violations with fines from $2,500 to $25,000 or more, plus Stop Work Orders that halt all construction immediately.
Work That Does NOT Require a Permit
The following cosmetic work is typically permit-free, according to NYC DOB guidelines:
- Painting and wallpapering
- Replacing flooring (non-structural)
- Installing new cabinet faces (no structural or plumbing changes)
- Minor cosmetic updates that don’t affect building systems
Important: When in doubt, always verify with a licensed contractor or architect before starting. What looks cosmetic may still trigger permit requirements under NYC code.
Work That ALWAYS Requires a Permit
In contrast, the following renovation work always requires a DOB permit before you begin:
- Kitchen remodels involving plumbing, gas lines, or electrical
- Bathroom remodels with new fixtures, layouts, or plumbing changes
- Structural wall changes (removing, adding, or moving load-bearing walls)
- Basement conversions or cellar egress window installations
- Electrical rewiring or new panel installation
- HVAC system installation or replacement
- Roof replacements or structural roof repairs
- Adding or enlarging windows or doors (structural openings)
- Building decks, porches, or exterior structures
- Enlarging or converting any living space
The 3 Types of Bronx Home Renovation Permits Explained
The NYC DOB issues three main categories of alteration permits. Therefore, which one you need depends entirely on the scope of your project.
Alt-1 (Alteration Type 1)
What it covers: Major changes that modify a building’s use, occupancy, layout, or egress, or projects that require a new or amended Certificate of Occupancy.
Examples: Converting a single-family home into a duplex, cellar-to-living-space conversion, vertical additions.
Typical approval timeline: 8–16 weeks
Alt-2 (Alteration Type 2)
What it covers: Multiple types of work that don’t change the building’s use or occupancy — such as interior demolition, plumbing + construction, or electrical + structural work. Consequently, most kitchen and bathroom remodels fall into this category.
Typical approval timeline: 4–8 weeks
Alt-3 (Alteration Type 3)
What it covers: Minor work involving only one trade or task — for example, replacing windows one-for-one, roofing, façade restoration, or simple repairs. Additionally, Alt-3 applications are simplified and may not require full architectural plans.
Typical approval timeline: 2–4 weeks
Specialty Permits (Required for Specific Work)
In addition to alteration permits, certain work types require separate specialty permits:
- Electrical Permit — required for most projects involving electrical work
- Plumbing Permit — a Licensed Master Plumber must file this
- Boiler Permit — ensures boilers meet NYC Building Code standards
- Scaffold/Shed Permit — required before you erect scaffolding over 40 feet
- Limited Alteration Application (LAA) — for plumbing, fire suppression, or oil burner work without construction
For Bronx Homeowners — The Most Common Scenarios:
- Kitchen remodel (moving plumbing + electrical) = Alt-2 + Plumbing Permit + Electrical Permit
- Bathroom addition with new fixtures = Alt-2 + Plumbing Permit
- Roof replacement (like-for-like) = Alt-3 or Limited Alteration Application

2026 Permit Fee Changes – What Bronx Homeowners Must Know
The NYC DOB calculates permit fees based on the total estimated construction cost of your project. Moreover, NYC Administrative Code §28-112.2 governs these fees — so they carry the full weight of city law.
New Payment Rules: Local Law 128 of 2024
Effective December 21, 2025, Local Law 128 of 2024 introduced significant payment rule changes. As a result, every Bronx homeowner and landlord filing in 2026 needs to understand this new structure:
| Permit Category | 2026 Payment Rule |
|---|---|
| Electrical work permits | Pay 50% of total fee at filing (minimum $130), remainder before DOB inspection |
| Non-electrical work — changes C of O | Pay 50% of total fee upfront (minimum $130), remainder before permit issuance |
| Non-electrical work — no C of O change | Pay 100% of total fee at filing (minimum $130) |
Furthermore, the minimum permit fee has increased from $100 to $130 under this new law.
What Else Did Local Law 128 Change?
In addition to the new payment rules, Local Law 128 aligned NYC with the 2020 National Electrical Code. This means tighter GFCI requirements, updated arc-fault protection rules, and stricter energy efficiency standards now apply to electrical work. Therefore, if you’re working from a 2024 or early 2025 estimate, plan for additional costs due to the increased electrical compliance requirements.
Typical 2026 Permit Cost Ranges for Bronx Renovations
| Project Type | Estimated Permit Fee Range |
|---|---|
| Minor alteration (Alt-3) | $130 minimum to several hundred dollars |
| Kitchen remodel (Alt-2, no C of O change) | $500 – $2,000+ depending on project value |
| Major structural alteration (Alt-1) | $2,000 – $10,000+ depending on scope |
| Professional filing/expediting fees (optional) | $3,000 – $15,000+ |
| Architect/engineer plan fees | $5,000 – $50,000+ depending on complexity |
Note: These are illustrative planning estimates. Your actual DOB permit fee depends on the specific construction cost of your project per the DOB’s fee schedule. Always get a written estimate from a licensed contractor.
New DOB Rules for 2026 – What’s Changed
The NYC DOB has issued several important updates effective February 2, 2026. Because these rules affect how you file, plan your Bronx renovation around them before you submit anything.
1. New Restrictions on Structural Permits in DOB NOW
Starting February 2, 2026, per Buildings Bulletin 2025-011, DOB NOW now restricts the issuance and renewal of a Structural permit connected to a new building, enlargement, or change in use when you file it as a separate Alteration filing. Specifically, if your alteration includes Structural (ST), Foundation (FO), or Earthwork (EA) work types tied to a larger development, you must now provide a linked New Building or Alt-CO job number.
2. Sidewalk Shed Permit Changes (Local Law 48 and Local Law 51 of 2025)
All sidewalk shed permits issued or renewed on or after February 2, 2026 will expire every 90 days and will no longer auto-renew in DOB NOW. Consequently, this change affects exterior and façade renovation projects that require temporary sheds. Plan accordingly — add permit renewals to your project timeline so you don’t face a lapse.
3. Loft Board Requests in DOB NOW
Starting February 2, 2026, you must submit Loft Board requests in DOB NOW: Build. Additionally, job filings on buildings with a Loft Law flag will not move forward until you have submitted a Loft Board Request and received a Letter of No Objection (LNO) or Loft Board Certification.
4. Worker Wallet Card – Mandatory Since July 1, 2025
As of July 1, 2025, the Worker Wallet card is the only accepted credential on NYC jobsites for specific worker qualifications. Therefore, all licensed contractors working on your Bronx renovation must comply with this rule. Brilliant Renovation LLC maintains full compliance with all current DOB worker requirements.
How to File for Bronx Home Renovation Permits — Step by Step
The NYC DOB processes all building permit applications through DOB NOW, the Department’s electronic filing system. Here is exactly how the process works from start to finish.
Step 1: Create Your DOB NOW Account
First, go to DOBNow.info and create an e-Filing account. You need this account to submit any permit application digitally. Without it, you cannot file anything online.
Step 2: Hire a Registered Architect or Professional Engineer
For Alt-1 and Alt-2 permits, a licensed Registered Architect (RA) or Professional Engineer (PE) must prepare and submit your plans. However, for simple Alt-3 work, the property owner of a 1–2 family home can sometimes file directly. Your RA or PE will also determine the correct permit type for your specific project scope.
Step 3: Gather All Required Documents
Next, you’ll need to compile: architectural drawings, technical engineering reports, an up-to-date property survey, an engineer’s sign-off where required, and any other agency approvals — for example, from LPC, DEP, or DOT — if applicable. Double-check all paperwork before submitting, because even minor documentation errors can lead to rejection.
Step 4: Submit Your Application Through DOB NOW
Once you have everything ready, submit the completed application, plans, and all documents marked “Prior to Approval” through DOB NOW. Also, pay the required permit fees according to the Local Law 128 rules outlined in Section 3 above.
Step 5: Navigate the DOB Plan Review
After you submit, a DOB plan examiner reviews the application for legal and zoning compliance. If the examiner raises objections, you must revise your plans and resubmit — so each revision cycle adds approximately 2–4 weeks to your timeline. To speed things up, a PE or RA can use Professional Certification (Pro-Cert), which often cuts review time from 15 business days down to just 1–2 days.
Step 6: Receive Your Permit and Post It On-Site
Once the DOB approves your application, you receive your permit. You must then post it visibly at the worksite before any work begins. Failure to post the permit on-site is itself a violation.
Step 7: Schedule and Pass DOB Inspections
Throughout construction, schedule all required inspections through DOB NOW at least 48 hours in advance. Key inspection milestones include foundation, framing, rough plumbing/electrical, and final inspection. Skipping required inspections leads to permit revocation, so stay on top of your schedule.
Step 8: Obtain Your Certificate of Occupancy
Finally, for Alt-1 projects or major structural changes, file for a Temporary or Permanent Certificate of Occupancy through DOB NOW after all inspections pass. This step legally closes out the permit and confirms your renovation meets NYC code.
Approval Timelines at a Glance:
- Alt-3 (simple): 2–4 weeks
- Alt-2 (mid-scope): 4–8 weeks
- Alt-1 (major/structural): 8–16 weeks
- Each objection/correction cycle adds ~2–4 weeks
- Pro-Cert filing can reduce review to 1–2 days for qualifying projects

Consequences of Unpermitted Renovation Work in the Bronx
Why Skipping a Permit Is Never Worth It
One of the most important reasons to work with a licensed, permit-savvy contractor is to avoid the severe consequences of unpermitted work. The NYC DOB actively enforces code violations throughout the Bronx, so homeowners who skip permits face serious financial and legal risks.
| Consequence | Details |
|---|---|
| Stop Work Order | All work must halt immediately. You must resolve the violation before work can resume. |
| Work Without Permit (WWP) Violations | Class 1 violations with base fines of $2,500–$25,000+ |
| ECB Summons | Additional civil penalties through OATH hearings |
| Daily Penalties | $500–$1,000 per day until you cure the violation |
| Property Liens | Unpaid fines become liens, blocking sale or refinancing |
| After-the-Fact Permit Costs | Retroactive permit fees cost 2–3× the original permit price |
| Insurance Issues | Your homeowner’s insurance may not cover damages from unpermitted work |
| Sale Complications | You must disclose unpermitted work, and it can kill real estate deals |
Important: Property owners are ultimately responsible for unpermitted work — not just the contractor. Therefore, always verify your contractor’s license in DOB NOW before any work begins.
Don’t Let Your Permit Expire Either
Furthermore, permits expire if you don’t substantially complete the work within 12 months of issuance. You must renew permits annually, and expired permits trigger DOB violations. As a result, set reminders at least 90 days before expiration to avoid unnecessary fines.

FAQ: Bronx Home Renovation Permits
Yes, in almost all cases. Even cosmetic kitchen renovations typically require at minimum an Alt-2 permit if you modify plumbing, gas lines, or electrical systems. Furthermore, if you move your kitchen (a “wet-over-dry” change), you also need both an Alt-2 filing and a Plumbing Permit. However, purely cosmetic changes like cabinet refacing or painting do not require a permit.
Yes — limited cosmetic work is permit-free. For example, painting, wallpapering, replacing flooring (non-structural), and cosmetic updates that don’t affect any building systems generally don’t require a permit. However, always verify with a licensed contractor before starting, because what seems minor may still trigger code requirements.
How long does it take to get a renovation permit in the Bronx?
It depends on the type of work. For instance, simple Alt-3 permits can receive approval in 2–4 weeks. Alt-2 permits typically take 4–8 weeks. In contrast, major Alt-1 projects with structural changes take 8–16 weeks or more. Additionally, using Professional Certification (Pro-Cert) can speed the process significantly for qualifying projects. Plan for additional time if the DOB issues objections that require plan revisions.
How much does a renovation permit cost in the Bronx?
The NYC DOB calculates permit fees based on the total estimated construction cost of the project. As of 2026, the minimum fee is $130, up from $100 under Local Law 128 of 2024. For typical residential renovations, expect permit fees to range from a few hundred dollars for minor work to several thousand for larger projects. In addition, architect/engineer fees and professional filing fees are separate costs on top of the permit fees themselves.
What happens if I renovate without a permit in the Bronx?
The consequences are serious. First, the NYC DOB can issue a Stop Work Order that halts all construction immediately. Work Without Permit (WWP) violations also carry base fines of $2,500–$25,000 or more. Furthermore, daily penalties of $500–$1,000 can accumulate until you cure the violation. Unpaid fines then become property liens, blocking any sale or refinancing. As a result, retroactive permits cost 2–3 times more than filing upfront — and your homeowner’s insurance may not cover damages from unpermitted work.
What is the DOB NOW platform and how do I use it?
DOB NOW is the NYC Department of Buildings’ electronic filing platform where you submit permit applications, renewals, inspections, and certificates of occupancy. You can also use DOB NOW to check permit status online, or alternatively call the DOB Bronx office at (718) 960-4700. In most cases, your licensed contractor and architect handle all DOB NOW filings on your behalf.
