What DOB Permits Really Are
If you're planning a renovation in NYC, you've probably heard about DOB permits. But what are they really? When do you need one? And what happens if you skip them?
We've filed thousands of DOB permits over 20+ years in NYC. The system feels complicated until you understand the basics. Then it's just paperwork that protects you, your neighbors, and your investment.
Jump to Permit TypesWhy DOB Permits Matter for Your Property
Insurance & Liability
Permitted work passes safety inspections. Insurance covers permitted work. If unpermitted plumbing causes a flood damaging neighbors, your insurance may deny the claim entirely.
Property Value & Sales
Future buyers expect permits. Unpermitted work shows up on title searches and DOB records. Buildings can lose certificates of occupancy. Some buyers walk away from violations.
DOB Permit Types for Residential Renovations
NYC uses different permit types depending on scope. These are the six you'll most likely encounter on a home renovation.
PW1 — Master Plan App
The master permit application covering overall scope. Architect or expediter submits to DOB with drawings and supporting documents. Most projects start here.
ALT-1 — Major Alterations
Big work involving changes to certificate of occupancy, such as combining apartments or converting units. Takes longer and costs more than ALT-2.
ALT-2 — Most Residential
Covers kitchen remodels, bathroom remodels, layout changes, and most interior work. This is the most common filing for typical NYC home renovations.
ALT-3 — Minor Work
Small jobs that don't require full plan review. Some minor scope qualifies, though most residential renovations still need ALT-2 instead.
PL — Plumbing (LMP)
Filed by a Licensed Master Plumber for all plumbing work. Required separately from PW1. Bathroom and kitchen rough-ins always need this filing.
ELEC1 — Electrical (LME)
Filed by a Licensed Master Electrician for all electrical work. Required for new circuits, panel upgrades, and service entrance changes.
Risks of Working Without DOB Permits
If your contractor suggests skipping permits to save time or money, here's what's actually at stake — for you, not them.
DOB Stop Work Orders
Neighbors or building staff can report unpermitted work. DOB freezes your renovation until permits are filed retroactively — costing more and taking weeks longer.
Civil Penalties ($1.5K-$25K+)
DOB issues civil penalties from $1,500 to $25,000+ for unpermitted work. Repeat violations and Class 1 violations can hit much higher numbers.
Insurance Denials
Damage from unpermitted plumbing or electrical work often isn't covered. If a flood damages your apartment and neighbors, you're personally liable for everything.
Sale & Title Issues
Buyers and their attorneys ask about permits. Unpermitted work shows on title searches and DOB records. Closings get delayed. Some buyers walk away entirely.
Retroactive Legalization
Legalizing work after the fact requires filing all the original permits, plus extra DOB scrutiny. Can take months and cost several times the original permit fees.

DOB Permits NYC FAQs
01 Do I need a DOB permit to renovate my kitchen in NYC?
Yes, in most cases. Moving plumbing, electrical, or structural elements all require DOB permits. Cosmetic-only kitchen work like cabinet refacing or paint may not. A licensed NYC contractor confirms what your specific project requires.
02 Can I file a DOB permit myself?
Some homeowners file simple permits themselves through DOB NOW. Most renovations need licensed professionals to file: an architect for plans, a Licensed Master Plumber for plumbing, a Licensed Master Electrician for electrical.
03 How long does a DOB permit take to issue in NYC?
Simple plumbing or electrical permits can issue in 1 to 2 weeks. Full ALT-2 alteration permits with architectural plans take 4 to 8 weeks. Complex multi-discipline projects can take 3 to 4 months.
04 What is a Licensed Master Plumber in NYC?
A Licensed Master Plumber is a plumber licensed by NYC to file plumbing permits and supervise plumbing work. NYC requires LMP filing on virtually all plumbing renovations, including kitchen and bathroom rough-ins.
05 What happens if my contractor works without permits?
DOB can issue Stop Work Orders, civil penalties of $1,500 to $25,000, and require retroactive permit filing. Insurance may deny claims related to unpermitted work. Future home sales become complicated when title searches reveal violations.
06 How much do DOB permits cost for a NYC renovation?
Permit fees range from $1,500 for simple plumbing work to $25,000 for large multi-room renovations with structural changes. Most kitchen or bathroom remodels run $2,000 to $5,000 in total permit and filing costs.
07 Do co-op renovations need DOB permits?
Yes. Co-op board approval is separate from DOB permits. You typically need both. Board approval allows the work in the building. DOB permits make the work legal and inspected by NYC code authorities.
