How to Revise a Building Permit in NYC (PAA Guide)
To revise an already-approved NYC building permit, the applicant of record files a Post-Approval Amendment (PAA) on the existing job number through DOB NOW: Build (or eFiling, for job types not yet migrated), describing the change from the originally approved plans; the current PAA fee is $130, per NYC DOB's Local Law 77 of 2023 fee schedule effective July 29, 2023.
A Post-Approval Amendment (PAA) is filed against the specific, already-open DOB job number, not as a new application. NYC DOB's own PAA fact sheet and its DOB NOW: Build PAA step-by-step guide describe the filing as covering changes to scope, declared cost, or other details of an approved job after the fact.
The applicant of record for that job (typically the architect, engineer, or filing representative who filed the original application) submits the PAA in DOB NOW: Build, attaching updated drawings or a description of what changed since the last approved filing. DOB then reviews the amendment on that same job record.
No additional fee applies to edit a PAA that is still open, per NYC DOB's guidance; the $130 fee applies to the initial PAA submission. This tool, PermitRevisionDesk, does not file PAAs on an applicant's behalf; it compares dated BIS and DOB NOW snapshots you provide (or a recent public snapshot) so you can see what changed between two observations of the same job, with the original city source record linked for every entry.
Frequently asked
Where is a PAA filed?
Through DOB NOW: Build for job types that use it, or eFiling for job types that have not migrated, per NYC DOB.
Does a PAA replace the need for a new permit for unrelated new work?
No. A PAA amends the existing, already-approved job. Work outside that job's original scope typically needs its own new filing, per NYC DOB's PAA guidance.
