Ask
Answers that show their work.
Ask anything about your co-op in plain English. Every answer arrives with citations to the exact passage — section, verbatim quote, the source doc — so your board can verify before relying on it.
No hedging. No “I think the bylaws say…” No more board members giving conflicting answers from memory.
Yes — for the parts that touch plumbing, electrical, or load-bearing walls. Your proprietary lease requires written board approval before any alteration that affects building systems or structure. Cosmetic-only work (tile, vanity, fixtures swapped at existing connections) doesn't need a vote, but you do need to notify the managing agent in advance.
Most boards also require an alteration agreement, COI from the contractor, and a $500 refundable deposit.
