Does Hewlett Neck, NY have zoning, and what does it allow?

Yes. The village zoning law applies to all land within the corporate limits of the Village of Hewlett Neck¹. The village is divided into four districts, Residence A, B, C and D, shown on the zoning map⁴.

Lot sizes depend on the district: the minimum lot is 5,000 square feet in Residence A, 15,000 in Residence B, 30,000 in Residence C and 40,000 in Residence D⁶. Front yards run from 20 feet in Residence A to 30 feet in Residence C and D, and side yards from 10 feet in Residence A to 20 feet in Residence B, C and D¹⁰. Buildings in all four districts are capped at 2.5 stories and 30 feet⁷.

Short-term rentals are not allowed: no building or premises may be used for transient rental in any district⁸. Dividing a lot so that either piece falls below its district minimum is barred¹¹.

Do you need a building permit in Hewlett Neck, and who issues it?

Yes. Inside the Village of Hewlett Neck it is unlawful to construct, alter, repair, remove or demolish a building or structure without filing a written application with the village building inspector and obtaining a permit, subject to an exception for ordinary repairs². The application goes in on the form the building inspector requires¹².

The village's building code sits on top of the New York State Uniform Fire Prevention and Building Code⁵. Plans must be prepared by a registered architect or engineer when the work costs more than $5,000, when the building exceeds 15,000 cubic feet, or when the inspector finds structural safety involved². The building inspector examines premises with issued permits and makes the inspections¹³.

The village posts its permit forms and fee schedule on its building department page¹⁴. Hewlett Neck issues its own building permits, so the Town of Hempstead and Nassau County are not the office for work inside the village.

How do septic permits work inside Hewlett Neck?

The village's own code does not answer who approves septic systems, and we could not confirm a village septic rule. Nassau County's Department of Health runs the county's on-site sewage disposal program, and a SPDES permit from that department is required before sanitary waste is discharged into the ground after approved construction¹⁵.

For a single home, the county tells owners building a house outside a new realty subdivision or renovating one to contact the local building department for septic approval requirements⁹. Inside Hewlett Neck, that means the village building inspector¹⁴. Developments of 5 or more lots go to the county Health Department for water supply, sewage disposal and drainage plans¹⁶.

Where public sewer serves the area, homes must connect to the sewer and old septic systems must be properly abandoned¹⁷. Call the Bureau of Environmental Engineering to confirm which applies to a given address¹⁷.

Can you live in an RV or tiny home in Hewlett Neck?

We could not confirm an answer. The village code was not found to contain an explicit rule on RV living, camping or tiny homes, and the village zoning chapter should be read for the permitted uses in each district. Ask the building inspector at the village office before planning anything other than a standard one-family house¹⁴.

The zoning in Hewlett Neck is a residential framework with four districts⁴, and short-term rental is prohibited in every district⁸. Treat any plan to live in a temporary or nonstandard structure as needing written confirmation from the village first.

Building a home in Hewlett Neck: the steps, in order

Confirm the district (Residence A, B, C or D) and check lot size, yards and the 30-foot height limit⁴⁶⁷.
Ask the building inspector whether the work needs a zoning variance or board approval before applying¹⁴.
File a written building permit application with the village building inspector, with architect or engineer plans where required².
Settle sewer or septic with the Nassau County Department of Health, Bureau of Environmental Engineering¹⁷.
Keep inspections moving through the building inspector¹³.
Get a certificate of occupancy: the state requires one for work done under a building permit¹⁸.

What stays with Nassau County, and what to check before you buy?

Septic and sewage disposal approvals stay with the Nassau County Department of Health, not the village³. Nassau County does not zone; zoning is administered through city, town and village laws, with the county planning commission reviewing referred actions¹⁹. Subdivision of land near a municipal boundary can also involve the county Planning Commission²⁰.

For land outside the village, see the Nassau County page. County-level figures: Nassau County's effective property tax rate is 1.5%²¹ and the typical home value is $859,544²². Hewlett Neck's own tax bill depends on the village, town and school district, so confirm with the village clerk before closing²³.

Watch-outs

Hewlett Neck sets its own zoning and issues its own building permits, so the Town of Hempstead and Nassau County planning counters are not the right office for work inside the village¹².
We could not confirm village permit fees, floodplain rules or driveway rules; ask the building inspector before you budget¹⁴.
Plans by a registered architect or engineer are required when work costs more than $5,000².
Transient or short-term rental is prohibited in every Hewlett Neck zoning district⁸.
