Do you need a building permit in Sleepy Hollow, NY?
Yes. Inside the Village of Sleepy Hollow, a building permit is required for any work that must conform to the Uniform Code or the Energy Code, including construction, enlargement, alteration, removal or demolition of a building or structure1. That includes new residential construction.
The village lists a short set of exemptions, such as certain repairs valued at $2,500 or less, but an exemption never authorizes work that violates the codes, and the repair exemption does not cover structural, egress, building-system or fire-protection work1. Work may not start until the Building Inspector issues the permit1.
After construction, a certificate of occupancy or certificate of compliance is required for work done under a building permit5. We could not confirm any owner-builder exemption from village permits; ask the Building Department before you plan to do the work yourself.
Who issues building permits in Sleepy Hollow, and how do you reach them?
The Village of Sleepy Hollow issues its own building permits; Westchester County does not. The village Building Department, run through its Department of Architecture, issues all construction-related permits and certificates of occupancy or compliance10. Call 914-366-5124 or visit 28 Beekman Avenue10.
Applications are written on a form the Building Inspector provides or accepts, signed by the owner or an authorized agent, and include the Tax Map number, street address and at least three sets of construction documents11. The building-permit fee is paid when you submit the application9, and the Board of Trustees sets the fee schedule by resolution9.
Does Sleepy Hollow have zoning?
Yes. The village adopted its own zoning chapter (Chapter 450) and applies it to land inside village limits2. The code lists zoning districts and a zoning map, and links a Schedule of Regulations4. Westchester County does not zone; zoning is handled by each city, town and village12.
We could not confirm the numbers that matter most to a buyer, including minimum lot size, setbacks, lot coverage, height limits and whether accessory dwelling units are allowed. Those depend on the district your parcel sits in, so pull the Schedule of Regulations from the village code and confirm with the Building Department's zoning inspector before you buy.
Subdividing a lot in the village is regulated and moves through sketch-plat, preliminary-plat and final-plat stages6.
Can you live in an RV or tiny home in Sleepy Hollow?
No RV. Village law makes it unlawful to occupy any camper, trailer, recreational vehicle, motor home or motor vehicle for living or sleeping anywhere in the village, or to connect one to electric, water, gas or sewer, except in a duly established trailer park3. Living in an RV on your lot while you build is therefore not an option.
We could not confirm any rule on tiny-home occupancy or short-term rentals inside the village. Ask the Building Department before you buy or build one.
How do septic permits work in Sleepy Hollow?
We could not confirm who approves septic systems on village lots, or whether a given lot is on sewer. Many village addresses may connect to public sewer, but the village code material we reviewed did not state a connection rule.
What is clear: Westchester County's Department of Health reviews and permits new subsurface sewage treatment systems across the county13, and licenses septic contractors14. New York State rules also require health-department approval of plans before building an alternative system15. Call the county Department of Health at (914) 995-7285 before assuming either answer for your address16.
Building a home in Sleepy Hollow: the steps, in order
- Confirm your parcel's zoning district and the Schedule of Regulations with the Building Department4.
- Check whether the lot is in a mapped flood hazard area; development there needs a floodplain development permit7.
- Ask the County Department of Health about sewer or septic for the lot13.
- Submit a building permit application with construction documents and pay the fee11.
- Wait for the Building Inspector's permit before starting work1.
- Notify the Building Inspector when work is ready for inspection and keep it exposed until accepted17.
- Obtain the certificate of occupancy or certificate of compliance before moving in5.
What stays with Westchester County, and what to check before you buy
The county does not issue building permits or set zoning for village land. It handles septic licensing and health review13, and its Planning Department only reviews certain actions that municipalities refer to it. For land outside the village, see the Westchester County page.
County-level numbers give context: Westchester County's effective property tax rate is about 1.6%18, and the typical home value is about $879,00019. Check flood maps, the zoning district and sewer status before you make an offer.
Watch-outs
- Living in an RV is unlawful anywhere in Sleepy Hollow, including on your own lot during construction3.
- Work must stay exposed until the Building Inspector inspects and accepts it, so do not close up walls early17.
- We could not confirm the district lot-size, setback or accessory-dwelling rules; get them from the village Building Department before you buy4.
- We could not confirm who handles septic approval inside the village; call the Westchester County Department of Health16.
