Common Questions

ADU Permits & Approvals — Frequently Asked Questions

What Los Angeles homeowners ask most before starting an ADU project.

How long does ADU permitting take in Los Angeles?
Through LADBS, standard ADU plan check currently runs 10–16 weeks from a complete submission. Smaller LA County cities are faster: Culver City and Burbank typically run 8–12 weeks; Pasadena and West Hollywood run 10–14 weeks. Garage conversions and JADUs often clear faster than new detached ADUs. We give you a city-specific timeline estimate based on current conditions.
Who manages the permit process, me or ADU Build LA?
We handle everything. Our team prepares all plan check documents, manages the initial submission, responds to correction notices, coordinates with city plan reviewers, and schedules every required inspection. You won't need to visit a permit counter or correspond with a city department. We manage the full process from first submission through final sign-off.
What is a correction notice and how does it affect my timeline?
A correction notice is the city plan reviewer's written list of items to revise or clarify before the permit is approved. Correction rounds are normal, nearly every project receives at least one. Timeline impact depends on turnaround speed. We respond to correction notices within a few business days and resubmit immediately, which minimizes delay.
What does LADBS plan check involve for an ADU?
LADBS plan check reviews your ADU drawings for zoning compliance (setbacks, height, coverage), structural adequacy, Title 24 energy compliance, and building code requirements. Our submitted package includes architectural plans, structural engineering drawings, energy calculations, and a completed zoning compliance worksheet. A thorough initial submission reduces correction rounds and speeds approval.
Do I need separate permits for electrical, plumbing, and mechanical work?
Subpermits for electrical, plumbing, and mechanical systems are typically pulled as part of the overall building permit, not separate standalone filings. We manage all subpermits, coordinate the required inspections for each trade, and obtain final sign-off on all systems before the certificate of occupancy is issued.
Can you handle permitting if I already have architectural plans from another designer?
Yes. We offer standalone permit management for projects where design is already complete. We review the existing plans for code compliance issues before submission, prepare any supplemental documents the city requires, and manage the full plan check process. We'll flag any design issues that would cause corrections before we file.
