Local Knowledge, Local Results
Why Campbell HomeownersChoose True Builders.
Campbell lots tend to be modest, so good design matters: a well-placed backyard ADU, an efficient garage conversion or a single-story rear addition can add a lot of living space without overwhelming the yard. Homes near downtown can fall within the historic district, where exterior changes get extra review, and the San Tomas area has its own neighborhood plan with design standards. We work through the City of Campbell’s requirements so your project is approved the first time.
You’ll get a fixed construction price and one project manager from start to finish.

Campbell Permits & Rules
What to Know Before You Build in Campbell.
We handle every permit. Here's the short version of what Campbell typically requires for common projects:
- Historic district — Exterior changes to properties in Campbell's downtown historic district typically require historic preservation review.
- San Tomas area — Additions and new homes in the San Tomas neighborhood are reviewed against its area plan and design standards.
- ADUs — Approved ministerially under California ADU law; detached ADUs need only 4-foot side and rear setbacks.
- Remodels — Permits are required when plumbing, electrical or structural elements change.
- Trees — Protected trees require a permit to remove, so we identify them before designing additions or ADUs.

CAMPBELL FAQS
Local Questions, Answered.
Often, yes. With the 4-foot setbacks state law allows, many Campbell lots fit a 500–800 sq ft detached ADU or a garage conversion. We confirm fit with a site review.
What you're building matters most: an office or bonus room without a kitchen costs far less than a legal studio or one-bedroom ADU. Slab condition, distance to the sewer line, electrical panel capacity and finish level also affect the price. We give you a fixed price after a free site visit.
Yes. Older bungalows often need foundation, electrical and plumbing upgrades, and we plan those along with the design details that give the home its character.
Simple remodel permits can be issued in days to a few weeks; additions and ADUs usually take 2–4 months including plan check.
Scope is the biggest factor. A same-layout refresh, a signature remodel with semi-custom cabinetry and layout changes, and an estate-level custom kitchen are very different projects. Moving plumbing, gas lines or walls, cabinetry and countertop selections, appliances and city permit fees also play a role. We give you a fixed price after a free site visit.
Plans and permits typically take 8–14 weeks, and construction of a detached ADU usually takes 16–22 weeks once permits are issued, so most detached ADUs are finished in about 6–9 months. Garage conversions and JADUs are usually faster.
