As per Buffalo's code requirements, please pull all required permits for any property work. If you are hiring a contractor, they must be licensed in the City of Buffalo. Contractors should pull permits for any work that they do. If any work is subcontracted, all subcontractors MUST ALSO BE LICENSED. This helps ensure that property work plans are reviewed, work is done safely, and that people who have proper experience perform this work. Inspectors WILL fine people for work done improperly or without permits.
