Garage Conversion Permit

Permit packages for garage conversions to ADUs or living space — change-of-use, slab, egress, and energy compliance.

The Challenge

Garage conversions are popular ADU projects but require change-of-use permits, foundation/slab upgrades for habitable use, egress, energy compliance, insulation, and moisture control. Skipping permits or engineering creates unsafe space and blocks resale.

How QuiPermit Helps

QuiPermit handles the full garage conversion permit package — change-of-use, slab engineering, egress, energy, and moisture compliance — and expedites approval.

The Process

1) Confirm conversion scope (ADU vs living space). 2) Engineer slab, insulation, egress, and energy compliance. 3) Prepare change-of-use and ADU paperwork. 4) Submit and expedite.

What's Typically Required

Floor plans, sealed structural engineering (slab, egress openings), energy compliance, insulation/moisture details, and change-of-use/ADU paperwork.
