Building permits are required for most construction in Richmond County, New York, the borough of Staten Island, and the NYC Department of Buildings issues them under the NYC Construction Codes12. New York City zoning also applies, with the parcel's district and use controlling such matters as setbacks, lot coverage and building height3456.

Do you need a building permit in Richmond County (Staten Island), New York?
Yes. The majority of construction in Richmond County requires one or more NYC Department of Buildings permits before work begins1. New Building, Alteration-CO and Alteration permits cover different scopes, and most permits are obtained through DOB NOW: Build, while specified applications or renewals remain in other DOB systems1. Projects filed under the current regime are governed by the NYC Construction Codes rather than the statewide Uniform Code2. Required inspections depend on the work and code provisions; applicable construction, special, progress and final inspections must be completed for sign-off13.
Who issues building permits in Richmond County, and how do you reach them?
The NYC Department of Buildings' Staten Island Borough Office at Borough Hall on Richmond Terrace is the local contact for building permits and certificate-of-occupancy processing7. The office publishes separate customer-service, Certificate of Occupancy and Construction Development phone lines7. Start there to identify the correct filing path and inspections for the proposed work; required inspections vary with the work type and applicable code provisions113. A new building needs a certificate of occupancy, and an existing building needs a current or amended certificate when its use, egress or occupancy type changes12.
Does Richmond County have zoning?
New York City zoning applies throughout Richmond County, but the requirements vary by zoning district and use3. Confirm the district assigned to the parcel before designing or buying: NYC zoning publishes district-specific rules, including Staten Island provisions for certain commercial districts and adjoining residential lots8. Setbacks can change with the district and with waterfront or special-district provisions4. Maximum lot coverage can depend on the district, slope and residence type, while authorizations or commercial-district exceptions may alter the result5. Building height likewise depends on the district and base-plane rules, with possible waterfront or special-district modifications6.
How do septic and sewer connections work in Richmond County?
Most of Staten Island is served by New York City's public sewer system, making private onsite systems uncommon9. For a parcel without sewer service, we could not confirm from the available local rules which authority issues the onsite-system approval or what inspections it requires; ask the DOB Staten Island Borough Office to identify the applicable agency before relying on a septic design7. Statewide, an ordinary sewage system discharging less than 1,000 gallons per day to groundwater, with no industrial or other non-sewage waste, does not need a separate SPDES permit, but another health authority may still require approval before construction1415. Only about 8.6% of Richmond County soils are rated without severe limitations for a conventional drain field, so make site feasibility a purchase contingency when public sewer is unavailable10.
Can you live in an RV or tiny home on your land in Richmond County?
We could not confirm a countywide rule allowing long-term RV occupancy, temporary camping or tiny-home occupancy in Richmond County. New York City zoning varies by district and use, so an RV or tiny-home proposal needs a parcel-specific zoning answer3. A tiny home built as a structure would also fall within the NYC permit system, under which most construction requires a DOB permit1. Ask the DOB Staten Island Borough Office about the proposed structure and occupancy before buying the parcel or placing a unit7.
Building a home in Richmond County: the steps, in order
- Identify the parcel's NYC zoning district and verify the proposed use, setbacks, lot coverage and height before design3456.
- Contact the DOB Staten Island Borough Office and select the filing type that matches the work71.
- If public sewer is unavailable, have the office identify the onsite-wastewater authority; only about 8.6% of county soils are rated without severe limits for a conventional drain field710.
- Obtain the required DOB permit before construction and arrange the inspections applicable to the work113.
- Complete final sign-off and obtain the required certificate of occupancy for a new building or a qualifying change in use, egress or occupancy1312.
What to check before you buy land in Richmond County
Richmond County has about 8,530 people per square mile and a Bolthole Index score of about 24.7 out of 1001617. Before buying, confirm the parcel's zoning district, allowed use, setbacks, lot coverage and height because those controls vary across NYC districts and special areas3456. Verify public-sewer availability, and if it is unavailable, make onsite-wastewater feasibility a contingency because only about 8.6% of county soils are rated without severe limitations for a conventional drain field910. Also ask the DOB Staten Island Borough Office whether the proposed work requires a New Building, Alteration-CO or Alteration filing and which inspections apply7113.
Watch-outs
- Do not apply the state's upstate permit exemptions or fee schedule to a Staten Island project; Richmond County construction is governed by NYC's permit system and construction codes12.
- We could not confirm whether Staten Island offers any owner-builder exemption from NYC's licensed-contractor and registered-design-professional requirements; ask the DOB Staten Island Borough Office directly before planning to self-perform work11.
