ADU permitting converts a design into documents that the reviewing city and building department can evaluate. ADLA coordinates the project information, plan disciplines, submittal path, and responses needed to move from concept toward an approved construction set.

One property, several reviewers
An ADU can touch zoning, building, structural, energy, utility, fire-access, and address requirements. The exact review path depends on the city and the site. We organize the required information around the project rather than treating permits as a single form.
Plans that communicate clearly
A coordinated set should explain existing conditions, the proposed work, dimensions, assemblies, systems, and code responses consistently across disciplines.
Site and floor plans
Exterior elevations and building sections
Structural and energy coordination
Agency comments and revision responses
Current rules, property-specific advice
ADU laws and local procedures change. We verify the current requirements during the project and direct homeowners to the applicable city source rather than relying on an old checklist.
Planning guidance
Cost and timeline depend on the property.
We do not advertise a fixed price or deadline before understanding the site and scope. These are the factors that usually deserve the earliest attention.
Primary cost influences
Survey and site documentation
Structural and civil engineering needs
Utility-agency requirements
Number of review cycles
Special site or historic conditions
Timeline guidance
Approval timing is controlled partly by the reviewing agencies and the completeness of the submission. We track project-specific milestones but do not promise a fixed agency review duration.
The authority depends on the property address. Los Angeles, Pasadena, Santa Monica, Glendale, and other incorporated cities use their own review departments and procedures.
Are preapproved plans automatically permitted on my lot?+
No. Preapproved plans can reduce design or review work, but the property still needs site-specific information and must satisfy current local and building requirements.
What can delay plan review?+
Incomplete site information, conflicting drawings, utility questions, special site conditions, and slow responses to correction comments can all extend the process.
