Do you need a building permit in the Village of Roslyn, New York?

Yes, for almost any construction. The Village of Roslyn requires a building permit for any work that must conform to the New York State Uniform Code or Energy Code, including construction, enlargement, alteration, removal, relocation or demolition of a building or structure2. No one may start that work without a permit from the code enforcement officer7. The village's own Building Department page says most home improvements and alterations in Roslyn require a permit8.

A certificate of occupancy or compliance is required for any work that is the subject of a building permit4, and work must stay exposed until the code enforcement officer or an authorized inspector has accepted it5. Fees are set by resolution of the village board of trustees; we could not confirm the amounts, so ask the Building Department9.

Who issues building permits in Roslyn, and how do you reach them?

Inside the village, the Village of Roslyn Building Department issues building permits and certificates of occupancy; the code enforcement officer administers the state Uniform Code and Energy Code for the village108. The office is at 1200 Old Northern Blvd., Roslyn, NY 11576, phone (516) 621-19618.

A reader inside Roslyn village should not use the Nassau County or Town of Hempstead building counters: village building permits are a village function. Work in the village's historic district also needs approval of the historic district board for exterior changes8.

Does the Village of Roslyn have zoning?

Yes. The village code includes a zoning chapter, Chapter 470, that applies to land inside Roslyn village limits1. Subdivision of land is regulated separately under Chapter 4126.

We could not confirm the zoning districts, minimum lot sizes, setbacks, height limits or dwelling-size rules from the village code, and we could not confirm rules on RVs, tiny homes, accessory dwellings or manufactured homes. Ask the Village of Roslyn Building Department which district a parcel is in before you buy, and read the district schedule in Chapter 470 of the village code1.

How do septic permits work in the Village of Roslyn?

Septic and sewage-disposal approvals in Nassau County are handled by the Nassau County Department of Health, Bureau of Environmental Engineering, not the village building office311. The department says residential and commercial facilities in areas served by public sewers must connect to the sewer11.

We could not confirm whether a particular Roslyn address is on public sewer or what the village's sewer chapter requires. Call the Nassau County Department of Health at 516-227-9692 and the village Building Department before assuming a septic system is an option for a lot in the village11.

Building a home in the Village of Roslyn: the steps, in order

  1. Ask the Village of Roslyn Building Department which zoning district the parcel is in and whether the planning board, zoning board of appeals or historic district board must review the project8.
  2. Confirm with the Nassau County Department of Health how the lot will be served by sewer or on-site disposal11.
  3. Apply for a building permit from the code enforcement officer; do not begin work first7.
  4. Keep work exposed for the required inspections, including footing, foundation, framing and a final inspection5.
  5. Obtain a certificate of occupancy or compliance before use4.
