Remodeling a Kitchen or Bathroom in a NYC Co-op or Condo: Approvals and Rules
What to expect when remodeling a kitchen or bathroom in a New York City co-op or condo: board approval, insurance, work hours and licensed trades.

Remodeling in a New York City apartment is different from remodeling a house. The building has rules, your neighbors share walls and floors, and the work needs approval before it starts. Knowing the process early can save weeks.
Rules vary from building to building, so treat this as a general guide and always read your building’s own alteration policy.
Step 1: ask management for the alteration rules
Before you hire anyone, contact your managing agent or board and ask for the alteration policy and application. It usually lists what needs approval, what documents to submit and what fees apply.
Step 2: submit plans and an alteration application
Most co-ops and many condos require an alteration agreement. You may need a scope of work, drawings, and details on materials. Kitchens and bathrooms that touch plumbing, gas or walls often need more review than cosmetic work.
Step 3: insurance and contractor paperwork
Buildings commonly require the contractor to provide certificates of insurance naming the building and management as insured. Some also ask for proof of licensing and references.
Step 4: licensed trades and permits
Some work must be done by licensed professionals, such as plumbing and gas, and some projects need a permit from the city. A good contractor tells you what applies to your project and coordinates it.
Step 5: schedule around building rules
Expect limits on work hours and noise, rules for using the elevator, and requirements to protect hallways and common areas. Deliveries and trash removal often need to be booked in advance. Water shut-offs have to be arranged with the building.
Tips to avoid delays
- Start the approval process before ordering cabinets.
- Do not begin demolition before you have written approval.
- Give your contractor the alteration policy at the first meeting.
- Plan extra time for approvals when the board meets only monthly.
