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.
We handle every permit. Here's the short version of what Campbell typically requires for common projects:
Detached, attached and garage ADUs for rental income or extended family.
Turn an existing garage into a legal ADU, in-law suite or home office.
Add a private suite of up to 500 sq ft inside the home you already own.
From refreshes to estate kitchens, typically $60K to $250K+.
Walk-in showers, primary suites and accessible bathrooms.
Bedrooms, primary suites and guest houses that match your home.
Whole-house renovations planned from 4–5 months to 12+ months.
One team for design, city approvals and construction.
2026 ranges for planning purposes. Your fixed price follows a site visit.
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.
Most run $120,000–$200,000 for a legal studio or one-bedroom ADU and $45,000–$90,000 for an office or bonus room without a kitchen.
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.
Most Campbell kitchen remodels fall into three levels: about $60,000–$95,000 for a refresh, $95,000–$150,000 for a signature remodel with semi-custom cabinetry and layout changes, and $150,000–$250,000 or more for an estate-level custom kitchen, plus city permit fees.
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.
