Compare current use to CO, Schedule of Occupancy and historic records.
Certificate of Occupancy & Legal Use Resolution
A Certificate of Occupancy documents the legal use and occupancy of a building where one is required. Missing, outdated or conflicting occupancy information can stop sales, refinancing, permits and violation closeout.
What This Service Covers
In NYC, DOB explains that buildings built before 1938 may not have required a CO unless later alterations changed use, egress or occupancy. In some cases a Letter of No Objection can document legal use instead.
Changes may require an Alteration-CO
Use, egress or occupancy changes can trigger a new or amended CO process.
Old buildings may need LNO instead
A missing CO does not automatically mean the building is illegal.
