From Plan to Permit in Just a Few Simple Steps

Building an accessory dwelling unit (ADU) in Massachusetts doesn’t have to be complicated. We’ve simplified the process so you can go from design to permitting quickly, affordably, and with confidence.

Step 1

Browse Plans

Choose from our collection of pre-designed, permit-ready ADU plans. Every design is Massachusetts code-compliant and tailored for efficiency, style, and comfort.

Step 2

Instant Plan Delivery

Once you purchase your plan, Tier 1 packages are available for immediate digital download. Higher tiers include cost estimates, engineering, and survey placement as needed.

Step 3

Site Placement

We coordinate with a licensed Massachusetts surveyor to overlay your chosen ADU onto your property, ensuring compliance with local zoning requirements.

Step 4

Engineer Review

For added assurance, Tier 3 includes a professional engineer stamp — giving you extra peace of mind when submitting to your local building department.

Step 5

Submit Permit Package

With your plans, site placement, and (if chosen) engineer stamp, you’re ready to submit directly for permitting. No special permit is needed in most towns.

Step 6

Build Your ADU

Once approved, your general contractor can begin construction — bringing your ADU from blueprint to reality.
