Who can pull the adu builder permit on my Palo Alto project?

What gets rejected most often on Palo Alto adu builder plan checks?

On Palo Alto adu builder submittals to Palo Alto Planning & Development, the three most common rejection causes are: Incomplete Title 24 forms — most common single-issue rejection; Site plan missing setbacks, easements, or existing tree protection; Structural calcs not matching the architectural set. Catching them on day one shaves 4–8 weeks off the typical cycle.

Can I start the adu builder job before the Palo Alto permit is issued?

No — California law prohibits starting permitted work before permit issuance, and Palo Alto Planning & Development can issue a stop-work order plus penalty fees of 2–4× the permit cost. We schedule mobilization the same week permit issues, never before.

Does Palo Alto require a separate inspection for adu builder?

Yes — 8 inspections are typical: Setback / form-board inspection before foundation pour; Foundation rebar + post-tension inspection; Underfloor rough plumbing + electrical; Framing + shear inspection with structural observation; and final.

Is my Palo Alto property in a historic district — and does that change the adu builder permit?

Likely yes — exterior alterations on contributing structures in Palo Alto's historic overlays need design-review approval before plan check accepts the building permit. We file the historic clearance in parallel to keep schedules tight.
