Code: DOB (City building department)
Description: (New York City Department Of Buildings) is the New York City government agency that enforces building codes and zoning rules, issues permits, and inspects new and existing buildings in the five boroughs. This agency also monitors building safety, responds to complaints and emergencies, and works with other city offices to keep buildings safe for the public.
Practical Meaning: For a NYC homeowner, DOB is the main city office you deal with for building permits, inspections, Certificates Of Occupancy, and enforcement of building and construction rules. DOB can approve your projects when they follow the rules or issue violations, stop work orders, and other enforcement actions when they do not.
Where You May See It: DOB letters and notices, BIS Property Profile, DOB NOW public portal, permits and inspection reports, title reports, bank and attorney correspondence, contractor proposals and contracts.
Why It Matters: Knowing what DOB does helps you understand why the city requires permits, inspections, and Certificates Of Occupancy before and after work on your property. If you ignore DOB rules, you risk violations, fines, project delays, and problems with sales, refinancing, or insurance.
