Bronx condo and coop architectural changes (alterations) require board approval under an Alteration Agreement. NY RPL 339-v allows bylaws to require consent for structural, plumbing, and electrical modifications, and for changes visible from common elements.
Alteration Agreements typically require: contractor insurance (GL, WC, umbrella), licensed engineer drawings, NYC DOB filings, a refundable deposit ($1,000-$10,000), and compliance with building hours. The Business Judgment Rule (Levandusky v One Fifth Avenue, 75 NY2d 530) gives boards wide discretion in approving or rejecting alterations provided they act in good faith. Exterior changes in landmark districts (some Bronx neighborhoods like Longwood Historic District) require additional NYC Landmarks Preservation Commission approval. Combining or subdividing units almost always requires DOB approval and board consent.
