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.
Portola Valley is San Mateo County and largely hillside, with geologic review that is a genuine part of the schedule. A soils report is not optional here — it shapes the foundation design and therefore the price.
Permits. Work in Portola Valley is permitted through the Town of Portola Valley's building department. We carry the submittal and the plan-check corrections — that is our job, not yours.

What projects cost in Portola Valley
Published ranges, not a bait number. Bay Area construction runs above the national average and we would rather you see that now than after a site visit. Every project is quoted custom — these are the brackets we actually work in.
| Project type | Typical range |
|---|---|
| New Construction | From $500/sq ftGround-up, plus site work and soft costs. |
| ADUs | $300K–$360K for a good-quality buildPriced per project, not per square foot — roughly $13.5K–$18.5K of plans, survey and soils work is fixed no matter how small the unit is. Size, site conditions and finish level move it from there. |
| Home Additions | $130K–$490KBy square footage added and how much structure has to change. |
| Whole-Home Remodels | $130K–$490KA true to-the-studs rebuild is priced like new construction, not like a remodel. |
| Kitchen Remodeling | $24K–$45K typical$65K–$120K+ for high-end work — that is the top of the market, not the middle of it. |
| Bathroom Remodeling | $22K–$30K typical$20K is our floor. To the studs and waterproofed properly — we do not bid the $10K version. |
Our minimum project size is $20,000. Site conditions, utilities and structural findings move these numbers more than finishes do.
