About Our Team
Dedicated Permitting Specialists for LA County
We focus exclusively on accessory dwelling units. Since 2009, our team has navigated the complex permit process for over 200 custom units across Los Angeles.
ADU permitting requires exact knowledge of local municipal codes to avoid months of corrections. Instead of handing you off to an expeditor, we drive the process. We handle plan check submissions, city corrections, and clearances in-house, delivering a ready-to-build permit faster.

Plan Check
City engineers review the drawings for compliance with zoning, structural safety, and green building codes.
Corrections
We receive the city's correction list, update the drawings within a few days, and resubmit them to minimize delays.
