California Pre‑Approved ADU Plans & Fast‑Track Permits

Introduction

Navigating ADU (Accessory Dwelling Unit) permits in California used to be a slow, complex slog—often taking 6–12 months and costly architecture fees. Thanks to state-wide pre‑approved ADU plans and fast‑track permitting, cities like San Diego, Los Angeles, and San Jose now offer approvals in weeks—even days. Firms like Fortune ADU have become invaluable partners, guiding homeowners through every stage of the San Diego ADU Permit.

What Are Pre‑Approved Plans & Fast‑Track Permits?

1. Pre‑Approved ADU Plans

These are architectural blueprints already reviewed and approved by local planning departments. Homeowners can select them and skip custom design steps—saving $10K–$30K and months of time.

Santa Clara County offers free plans for 800 sq ft (2BR) and 1,200 sq ft (3BR) units.
San Jose issues same‑day permits when using pre-approved plans.

2. Fast‑Track Permitting

This process expedites reviews to weeks or days instead of months.

San Diego ADU Accelerator can deliver permits within about 2 weeks.
Los Angeles and San Jose have similar programs .
