Real reviews from real Palo Alto clients, neighbors of yours who have lived through the project and would do it with us again.

★★★★★

"We have a 1910 home in Old Palo Alto with a long list of historic constraints. The team worked through every layer of Palo Alto's review process and delivered a complete kitchen and primary suite remodel that looks like it has always been there. Truly outstanding work."

★★★★★

"Our Greenmeadow mid-century home had original everything: slab, beams, and glass. The team modernized the systems, added a second bathroom, and the home now performs like new construction but still reads authentically mid-century. The crew was meticulous and the project manager was outstanding."

★★★★★

"Built a JADU within our existing footprint and a detached ADU in the back of our Barron Park lot. Palo Alto's tree protection and ADU rules are complex, and they handled all of it. Both units are rented to graduate students and the finish work is impeccable."

Palo Alto FAQs

Common Questions From Palo Alto Homeowners

If you do not see your question here, call or message us. We will answer it straight.

Do you remodel mid-century post-and-beam homes in Palo Alto?
Yes. Palo Alto neighborhoods like Greenmeadow, Fairmeadow, and Royal Manor are full of these architecturally significant homes. We respect the architecture (post-and-beam framing, atriums, radiant slabs, floor-to-ceiling glass) and update systems, insulation, and finishes thoughtfully.
How long does Palo Alto's design review process take?
Palo Alto's planning and historic review can be significant. For an individually reviewed project, expect 12 to 20 weeks or more before permits issue. We submit complete, fully detailed sets and respond to comments fast to keep your timeline on track.
Can you work around Palo Alto's tree protection rules?
Yes. Palo Alto has strict heritage and protected-tree rules, including root protection zones, no-cut zones, and arborist requirements. We work with certified arborists, design foundations around trees, and use specialized techniques (helical piers, hand digging) to protect them.
Do you serve all parts of Palo Alto, including Crescent Park and College Terrace?
Yes. Crescent Park, Professorville, College Terrace, Old Palo Alto, and the downtown periphery are some of our most active project areas. We are familiar with Palo Alto's strict construction-hour and parking rules in these denser neighborhoods.
How much does an ADU cost in Palo Alto?
Detached ADUs in Palo Alto typically range from $400 to $700 per sq ft fully turnkey, reflecting higher finish standards, tree protection costs, and design review. Garage conversions and JADUs are more affordable. We provide a fixed-scope estimate after a site visit and design discussion.
