What Most Manhattan Co-op Boards Require
Unlike condo owners, co-op owners purchase shares in the corporation that owns the building rather than owning their apartment directly. The proprietary lease gives the board broad authority over renovations, and board approval is required before any work begins.
Alteration Agreement & Documentation
The alteration agreement outlines approval requirements, insurance obligations, and work-hour restrictions. Drawings, licenses, and a Certificate of Insurance are typically required.
Application & Board Review
Applications go to the management company first, then the board. Most buildings retain their own architect to review plans, and timelines range from one month to several months.
Feedback & Final Agreement
Boards may request modifications during review. Once approved, a legally binding alteration agreement is signed covering all terms and compliance conditions before construction begins.

Corniel is amazing. I hired Corniel for a commercial office renovation restoration. Not only did they do a fantastic job, they finished with coordinated scheduling and closeout and on budget.

We remodeled 3 bathrooms and Ruben was amazing. Everything we asked for, he made sure we were satisfied. Even when I changed my mind or asked for an additional thing, Waldy made it happen. We could easily contact him every day, and he always responded ASAP.Waldy is very experienced and knowledgeable, even offering helpful suggestions.
