Section 2: The Hurdle: Zoning, Permits, and the DOB
This is the most critical and often most confusing part of any home addition project in NYC. Before any construction can begin, you must have approved plans from the Department of Buildings (DOB). This process starts with understanding your property’s zoning regulations.
Key terms you need to know:
- Zoning District: Staten Island has various residential districts (like R1, R2, R3) that dictate what you can build. You can find yours on the official NYC Zoning and Land Use map.
- Floor Area Ratio (FAR): This determines the maximum allowable square footage for your home based on your lot size.
- Lot Coverage: The percentage of your property that can be covered by a building.
- Yard Requirements: Rules dictating the minimum size of your front, side, and rear yards.
