Department of Buildings (DOB) Permit
A Department of Buildings permit is required for virtually any construction work in NYC commercial spaces, including new buildouts, renovations, plumbing changes, electrical work, and changes of use or occupancy. Permits are filed through DOB NOW and require plans prepared by a licensed architect or engineer. The process involves plan review, inspections, and final sign-off.
Why It Matters for Operators
Unpermitted work is one of the biggest risks in NYC commercial real estate. Operating with unpermitted construction can result in DOB violations, fines of $5,000-$25,000+, forced closure, and voiding of your insurance coverage. Additionally, unpermitted work by a previous tenant becomes your problem when you take over a space—the DOB can require you to legalize or remove it.
FWDRE Insight
File your DOB permit application within days of lease signing—the review process alone takes 4-16 weeks depending on complexity. Use an experienced expediter (budget $3,000-$8,000) to navigate the DOB bureaucracy. For restaurant buildouts, we recommend a 'Plenary' filing that covers all work scopes in one application rather than multiple individual filings, which can create coordination nightmares.
