Tarrytown and Sleepy Hollow homeowners face the same permit requirements as the rest of Westchester County — but the village-level building departments have their own application forms and review processes. Here's what we've seen working in the river towns.
Tarrytown & Sleepy Hollow Permit Basics
Both villages require permits for new decks and significant structural replacements. The application must include a site plan showing setbacks from property lines (typically 5-15 feet on sides, more in rear depending on zone), footing details at 42" minimum depth, and complete framing drawings.
River town note: Many Tarrytown and Sleepy Hollow properties are in historic districts or have deed restrictions from HOAs. Check both before designing — a permit from the village doesn't override deed restrictions.
What Your Application Needs
- Survey or plot plan showing your property lines and existing structures
- Framing plan with beam spans, post sizes, joist spacing
- Footing details (42" below grade minimum)
- Elevation drawings showing guardrail and stair configuration

Footing inspection before pouring, final inspection when framing is complete. The permit closes after both pass. We attend all inspections on every project we build.
How the Permit Process Actually Works in Westchester
The permit process intimidates many homeowners, but it follows a predictable path. First, drawings are prepared showing the structure's dimensions, footings, and connections. These are submitted to the local building department with the application and fee. A plan reviewer checks the drawings against the building code — this is where incomplete packages get rejected and sent back, adding weeks. Once approved, the permit is issued and work can begin. During construction, the building department inspects at key stages (typically footings before concrete is poured, then a final inspection). The permit officially closes only after the final inspection passes.
The single biggest factor in how smoothly this goes is the quality of the first submission. A complete, accurate package gets approved on the first pass. A package missing footing details, setback dimensions, or required structural information gets kicked back — and each round trip adds two to four weeks. This is the main reason we prepare permit-ready drawings ourselves rather than relying on generic plans, which often don't account for Westchester's 42-inch frost depth requirement or local setback rules.
Why a Local Contractor Matters Here
A contractor who submits permits in this area regularly knows the specific requirements, the plan reviewers, and the common rejection reasons. That knowledge translates directly into faster approvals and fewer surprises. We handle the entire permit process as part of our projects — drawings, submission, responding to reviewer comments, and attending inspections — so you never have to deal with the building department yourself.
