Siding permits, HOAs and historic districts in Suffolk County
On Long Island, building permits are issued by the town or, inside an incorporated village, by the village. Here is what each covered town publishes about re-siding, as of November 2026.
The state rule behind the town rules
Last checked November 3, 2026
New York's Uniform Code lets a town or village exempt some work from permits, but only where its code enforcement program says so. One category it may exempt is repairs that don't affect the structural system, the means of egress or fire protection (19 NYCRR Part 1203, § 1203.3). So whether re-siding needs a permit is decided locally.Town by town
What each town says
- HuntingtonIts filing guide says no building permit is required for siding replaced in-kind with no structural changes, and asks you to contact the Building Department first.
- BabylonA permit is required before any construction or alteration project; the page does not mention siding. Ask the Building Department.
- IslipThe Building Division publishes a guide to when a permit is required. Ask its Permits Office about your job.
- SmithtownPermits for alterations come from the Building Department; its FAQ addresses roofs, not siding. Ask the department.
- BrookhavenPermits are required for many alteration projects; historic districts need Historic District Advisory Committee approval.
Historic districts and landmarks
In the Town of Huntington, the Historic Preservation Commission reviews applications for Certificates of Approval for designated landmarks and historic districts in the unincorporated town. In Brookhaven, Historic District Advisory Committee approval is required for projects within a historic district.
If your house is in a district or is a landmark, check before choosing a material. Changing cedar shingles or wood clapboard to another product, or changing the profile, is the kind of change a review board looks at.
Villages and homeowners associations
Incorporated villages can have their own building officials. In the Town of Huntington, for example, Asharoken, Huntington Bay, Lloyd Harbor and Northport have their own building officials (Town of Huntington 311). If your address is in a village, start there.
Condominiums and homeowners associations often have rules on siding color and material in their covenants. Those are private rules, not town permits; read them, and get any approval in writing before the contract is signed.
