Free Zoning Analysis for Your Property

Building an accessory dwelling unit starts with understanding what your property allows.
That’s why Granite State ADU offers a free, no-obligation Zoning Analysis to every homeowner considering an ADU.
This first step gives you a clear picture of what’s possible—before you spend a dime on design or construction.

Why a Zoning Analysis Matters

Every New Hampshire town has unique rules on setbacks, lot coverage, height limits, and wetlands or other overlays.
Even with the new state law (House Bill 577) expanding ADU rights, each lot is different.
A zoning analysis answers questions like:

  • Where on the lot can a detached ADU sit?

  • What maximum square footage is allowed?

  • Are there special conditions such as steep slopes, flood zones, or easements?

By knowing the constraints up front, we help you avoid surprises and keep your project on schedule.

What We Provide

Our complimentary analysis includes:

  • A review of your town’s zoning ordinance and any overlay districts

  • A study of setbacks, lot coverage, height restrictions, and driveway access

  • Checks for wetlands, floodplain, and other environmental considerations

  • An easy-to-read written report summarizing key opportunities and potential red flags

This report becomes the foundation for your ADU design and budget.

How It Works

  1. Share your property address (and a copy of your current septic plan if available).

  2. We research the zoning, compile a GIS-based site map, and highlight all relevant rules.

  3. We send you a clear report and set up a call to review next steps—at no cost.

This is the first step in our 4-Step ADU process and helps us deliver accurate design concepts and pricing from the start.

Your Next Step

Whether you’re planning a rental unit, an in-law suite, or a future downsizing option, the zoning analysis tells you exactly what’s possible.
It’s fast, free, and gives you the confidence to move forward. Just hit the button at the top right of this page to get started!
