Palo Alto ADU design & construction
Palo Alto’s guidebook labels State standards, City standards, required additional City standards and optional best practices separately. That distinction matters when choosing a more flexible local design option.

What matters for an ADU in Palo Alto
Permitting authority: City of Palo Alto — ADU/JADU Guidebook
Official local guidanceLocal rules and design checks
| Topic | Local guidance |
|---|---|
| Standard selection | Using City standards also invokes the applicable Additional City Standards; do not treat optional best practices as legal requirements. |
| Transit check | The guide maps major transit stops and El Camino Real’s transit corridor and directs owners to verify walking-distance eligibility with Planning. |
| Permit package | The City provides a dedicated new-residence / detached-ADU checklist in its Building application resources. |
Selected local requirements, not a complete zoning determination. Confirm the current rules for your address with the responsible agency.
Fees and budget checks
Obtain the current Building assessment and school-fee form from the project coordinator where applicable. Palo Alto directs applicants to the responsible school district; the district charge is separate from the City permit payment.
Palo Alto school-fee procedureHow to start the permit process
Review the parcel report and guidebook with the Planner on Duty, then use the City’s Building pre-application process. Complete submissions are converted into official permit applications before the requested fee payment.
