Pre‑Approved ADU Plans (AB 1332): How They Speed Up Permits in 2026
More California jurisdictions now publish pre‑approved ADU plan libraries. Used correctly, they can reduce design time and help shorten plan check.
Why This Matters for ADU Projects
Most homeowners want fewer revisions, faster approvals, and a smoother build. That’s why we align ADU Design, ADU permitting, and ADU construction from the start.
1. What Pre‑Approved Plans Actually Do
Pre‑approval typically applies to the plan set—your site still needs a site plan and local checks for setbacks, utilities, and access.
2. Where Homeowners Lose Time
Most delays happen when site constraints aren’t evaluated early (grading, access, utilities) or when revisions aren’t coordinated across disciplines.
Quick Checklist

FAQs

No—site-specific requirements still apply, but they can reduce back-and-forth on the plan set itself.
Are pre‑approved plans good for every property?
They work best when your site constraints are straightforward and the plan matches your goals.
