Permitting
ADU Permit Packages
Complete permit packages for accessory dwelling units and garage conversions.
Overview
Accessory dwelling units are one of the most permit-intensive residential project types in most jurisdictions. We produce the complete ADU permit package: architectural drawings, site plan, energy compliance documentation, utility connection details, and all supplemental materials required by the applicable building department and local ADU ordinance.
Why It Matters
ADU permit packages are heavily jurisdiction-specific. Local ADU ordinances vary significantly in setback requirements, owner-occupancy rules, design standards, and required supplemental documentation. Building the package without jurisdiction research first is the most common cause of correction cycles.
Package Includes
Existing and Proposed Floor Plans
Dimensioned floor plans showing existing conditions and the proposed ADU layout, including all new walls, openings, and fixtures.
Elevations
All building elevations showing the ADU exterior, heights, and relationship to the primary structure.
Site Plan with Setback Verification
Site plan confirming ADU placement within required setbacks, lot coverage calculations, and access.
Energy Compliance Forms
Title 24 or equivalent compliance documentation for the applicable jurisdiction.
Utility Connection Plan
Water, sewer, and electrical connection documentation for the new unit.
Jurisdiction Supplemental Forms
All required forms, owner affidavits, and documentation specific to the building department.

- Can you help with garage conversions?
- Yes. Garage conversions to living space are treated as ADUs in most jurisdictions and we handle the complete permit package, including change-of-use documentation.
- What is the typical delivery timeline?
- Most ADU permit packages are delivered within 10-15 business days of intake, depending on project complexity and completeness of site information.
- Do ADUs require energy compliance documentation?
- Yes. Title 24 or equivalent energy compliance is required in most jurisdictions. We include the required compliance documentation in every ADU package.
- Can you work from existing drawings?
- Yes. If you have existing site plans or partial drawings, we can use them as the starting point and build the complete package from there.
