If you own a co-op apartment in New York City and want to renovate, the first document you will deal with is not a construction contract. It is your building’s alteration agreement. This agreement sets the rules for your renovation, and until it is approved and signed, work cannot begin.
Understanding how the alteration agreement works is the best way to avoid the delays that frustrate so many NYC renovations. Here is what it is, what it usually requires and how to move through the process smoothly.
What Is an Alteration Agreement?
An alteration agreement is a contract between you, the shareholder, and your co-op corporation. It gives you permission to renovate your apartment and spells out the conditions you must follow while the work is underway.
Condos often have a similar document, sometimes called an alteration agreement or renovation application. Condo boards generally have less control than co-op boards, but most still require approvals, insurance and adherence to building rules.
The agreement protects the building, the other residents and the board. From the board’s point of view, your renovation carries risk: water leaks, structural issues, noise, damage to common areas and disputes with neighbors. The alteration agreement is how the building manages that risk.
What an Alteration Agreement Usually Covers
Every building writes its own agreement, but most cover the same core topics.
Scope of work and plans. You describe what you plan to do. For anything beyond simple cosmetic work, the board will usually want drawings prepared by a licensed architect or engineer.
Review by the building’s architect or engineer. Many buildings send your plans to their own professional for review. This reviewer checks for structural, plumbing, electrical and waterproofing issues and may ask for changes.
Contractor requirements. The building will ask for information about your contractor, including licensing and insurance. Some buildings have minimum experience requirements.
Insurance. Your contractor must provide certificates of insurance that meet the building’s coverage limits and list the correct additional insured parties, usually the co-op corporation and the managing agent.
Permits. If your work requires Department of Buildings filings, the agreement will require that permits are obtained before work starts and closed out when the work is finished.
Work hours and rules. Most buildings limit construction to weekday business hours. Some prohibit major renovations during the summer months.
Deposits and fees. Buildings often require a refundable security deposit and charge fees to cover the cost of reviewing your plans.
Timeline. Many agreements set a deadline for completing the work, with penalties if the project runs past it.
Special rules. This is where you will find rules like the wet over dry restriction, requirements for waterproofing in bathrooms and kitchens, and rules about sound insulation under new flooring.
The Approval Process, Step by Step
1. Get the agreement early. Ask your managing agent for the building’s alteration agreement and house rules before you finalize your design. Knowing the rules first saves you from paying for drawings you will have to redo.
2. Assemble your team. Choose an architect if your scope requires drawings, and choose a contractor who works in NYC co-ops regularly. An experienced contractor knows what boards look for and can prepare their part of the package quickly.
3. Prepare the package. A complete submission typically includes the signed agreement, drawings, a scope of work, the contractor’s license and insurance certificates, a schedule and any required deposits.
4. Building review. The managing agent and the building’s reviewer look at your submission and may come back with comments. Responding quickly and completely keeps the process moving.
5. Board approval. Once the review is complete, the board approves the project and the agreement is fully executed.
6. Permits and start. If DOB permits are required, they are obtained and posted, and construction can begin.
How Long Does Approval Take?
There is no single answer. A simple cosmetic project in a well-run building might be approved in a few weeks. A full gut renovation with plumbing changes, engineer review and DOB filings can take considerably longer.
The single biggest cause of delay is an incomplete submission. Missing insurance details, drawings that ignore building rules and slow responses to reviewer comments can each add weeks.
Common Mistakes to Avoid
- Designing before reading the rules. A kitchen or bathroom layout that violates the wet over dry rule will be rejected.
- Using a contractor without co-op experience. Boards notice when a contractor doesn’t understand building procedures, and insurance certificates that don’t match requirements are sent back.
- Underestimating the timeline. Build approval time into your plan, especially if you want to finish before a specific date.
- Ignoring summer rules. If your building restricts summer work, a spring approval may still mean waiting until fall to start.
