Your Building Department
Deserves Better Tools.
Interactive Resources for ADU Permitting, Compliance & Community Engagement
Six purpose-built tools plus a comprehensive field guide — designed by municipal professionals, for municipal professionals. Reduce counter time, grow your tax base, and make ADU approvals safe, consistent, and fast.
ADU Applications Are Surging.
Is Your Department Ready?
Massachusetts and Connecticut now mandate by-right ADU approval. Rhode Island, New Hampshire, Maine, and Vermont are following. Your building department is about to get a lot busier — and residents are watching.
Counter Time is Killing You
Your staff spends 30+ minutes per walk-in answering the same fee, zoning, and process questions. Our tools answer them instantly — online, 24/7 — before residents ever walk through the door.
Revenue You're Leaving on the Table
Every unpermitted ADU is lost tax revenue, uncollected permit fees, and an uninspected structure that puts residents at risk. Legalization programs bring them into compliance — and onto the rolls.
Legal Exposure Is Real
Inconsistent permit decisions, missing documentation, and opaque fee structures create legal liability. Standardized, transparent tools protect your municipality and your staff.
"The biggest risk isn't approving ADUs — it's being unprepared when the applications arrive."— The ADU Exchange Municipal Advisory Team
