Building in Atherton
Every city in our area is its own jurisdiction with its own review process. What's true in one does not carry across the city line — which is why this page exists rather than a single generic service-area page.
Atherton is San Mateo County jurisdiction, not Santa Clara, so the process differs from most of our service area. It is large-lot, heavily treed, and the review is exacting — which suits us. This is estate-scale new construction and whole-home renovation.
Permits. Work in Atherton is permitted through the Town of Atherton's building department. We carry the submittal and the plan-check corrections — that is our job, not yours.

What a Atherton project costs
We publish our real ranges rather than making you book a call to find them out, and our minimum project size is $20,000. What moves a number in Atherton is rarely the finishes — it is the site, the utilities and what turns up once something is opened.
Public record
Permits and ADU rules in Atherton
These are links to the city's own pages, not our summary of them. We carry the submittal and the plan-check corrections on a project we build, so this is not information you have to act on yourself. It is here because you should be able to check it either way.
Atherton submits through an ePlan portal, and it also requires a Town business license for the general contractor before the permit is issued and a subcontractor list before final inspection. Menlo Park Fire District sign-off is separate.
Pre-approved ADU plans. Atherton runs a pre-approved ADU plan program and is still building out its public gallery. Since AB 1332 took effect on January 1, 2025, California cities have had to run a pre-approved ADU plan program and post the approved plans publicly. Where a usable plan exists it can take real time and design cost out of a project, because the design has already been reviewed and only the site-specific work is left.
Links checked August 2026 and pointing at government pages. Cities change both their pages and their rules, so confirm anything current with the Town of Atherton's building department. We deliberately do not publish Atherton permit fees or review times here: those move, they vary by project, and a number that is out of date is worse than no number at all.
