NYC Apartment Renovation Rules: What You Need to Know Before You Start
Avoid delays, violations, and headaches—know the rules before you renovate.
Renovating an apartment in New York City is exciting—but it’s also filled with regulations, permits, and building-specific red tape. Whether you live in a co-op, condo, or rental, understanding the renovation rules upfront can save you time, money, and stress.
At One Stop Contractors NYC, we’ve guided hundreds of New Yorkers through the process—from Park Avenue prewar co-ops to Brooklyn loft conversions. Here’s what every apartment owner should know before starting a renovation in NYC.
1. Check Your Building’s Alteration Agreement First
If you're in a co-op or condo, your board likely has an alteration agreement—a formal document outlining what types of renovations are allowed, which require approval, and the process for getting started.
Common requirements include:
Detailed architectural plans
Proof of insurance from your contractor
Noise work hours (usually restricted to 9–5 on weekdays)
Elevator protection and debris removal plans
Tip: Submit your renovation proposal as early as possible. Some boards take weeks to review and approve.
2. Understand What Requires a NYC Department of Buildings (DOB) Permit
Not all apartment renovations require a DOB permit, but many do. Here’s a quick guide:
Renovation Type Permit Needed?
Cosmetic changes (paint, floors) ❌ No
Kitchen remodel (same layout) ✅ Often (for plumbing/electrical) Bathroom remodel ✅ Yes
Removing/moving walls ✅ Yes (plus structural review)
HVAC, electrical upgrades ✅ Yes
Window replacements ✅ Sometimes, if landmarked
Working without permits can result in stop work orders, fines, or resale delays—so it's essential to get this right.
3. Landmarked or Historic? You’ll Need Extra Approvals
If your apartment is in a landmarked building or historic district (common in neighborhoods like the Upper West Side, Greenwich Village, and Brooklyn Heights), any exterior work—including window replacements—must be approved by the Landmarks Preservation Commission (LPC).
Interior work usually doesn’t require LPC approval—but if you're touching anything visible from the street, you’ll need to follow landmark guidelines.
4. Plan for Noise Restrictions and Building Logistics
Even if your contractor is ready to go, your building may not be. Most buildings restrict noisy work to business hours, prohibit weekend work, and require scheduling use of service elevators for material deliveries.
You may also be required to:
Post a refundable damage deposit
Install floor protection
Use a licensed and insured contractor (which we are)
5. Get the Right Team—From Architect to Contractor
Some projects (like moving walls or updating plumbing stacks) require you to file plans through a licensed architect or engineer. Others can be handled by a general contractor—but experience matters.
At One Stop Contractors NYC, we coordinate everything:
Architectural drawings & DOB filings
Permit applications
Site protection and compliance
Communication with your co-op/condo board
Execution with licensed trades: plumbing, electrical, HVAC, tiling, and more
6. Expect Timelines to Be Longer Than You Think
Even a “simple” bathroom renovation can take 2–3 months when you factor in board approvals, permits, demolition, and inspections. Setting realistic expectations—and working with a team that manages logistics—is key to a smooth experience.
7. Communicate Clearly with Neighbors and the Building Manager
In tight NYC buildings, courtesy goes a long way. Give notice about noisy work, communicate timelines with building management, and ensure your contractor is tidy, respectful, and mindful of shared spaces.
(We train our team to be exactly that.)
