Establish authority, responsibility, access, and resident communication

Review lease, condo documents, maintenance responsibility, insurance, prior repairs, and building plans with the appropriate advisers. Do not assign responsibility from leak location alone.

Build a shared timeline with unit, fixture, stack or branch if documented, water shutoff impact, resident reports, photographs, and access limits while protecting personal information.

Identify who may request proposals, sign, approve openings, authorize changes, contact the town or insurer, notify occupants, relocate residents, and restore finishes.

Keep the final system map, affected units, notices, access record, contract, permit, inspection, interruption, test, restoration, invoice allocation, warranty, and remaining responsibility.
