Description
Planning to Build an ADU or Expand Your Home?
Accessory Dwelling Units (ADUs) and major home additions require a higher level of documentation than small exterior projects. Cities often conduct deeper zoning and spacing reviews before approval.
Our ADU & Home Addition Site Plan is specifically created for larger residential projects that require detailed layout clarity, setback validation, and structured formatting for municipal review.
This plan is ideal for:
-
Detached ADUs
-
Attached ADUs
-
Garage conversions
-
Home expansions
-
Second-story additions
-
Major structural additions
-
In-law suites
-
Rental unit conversions
We draft a professional, detailed layout showing accurate structure placement, property boundaries, driveway access, and required spacing from property lines — helping reduce delays during city review.
No site visit required.

Why This Plan Is Different
ADUs and major additions typically require:
-
Larger structure placement accuracy
-
Careful setback compliance
-
Lot coverage limitations
-
Access and driveway review

Utility routing clarity
This plan accounts for those requirements and is designed to meet common municipal review standards across U.S. jurisdictions.
