General Contractor in Walnut Creek, CA
Kitchens, baths, ADUs, and full home additions across Walnut Creek, built by one licensed team that self-performs every trade. From Northgate and Rudgear Estates to the Parkmead ranches, we handle design, permits, and construction under a single contract.
Remodeling and building across Walnut Creek
Walnut Creek homeowners tend to invest in the home they have rather than trade up in this market, and much of the city’s stock — the mid-century ranches in Parkmead and Walnut Heights, the established homes of Northgate and Rudgear Estates — is ready for a serious update. Rhino Builders has built across Contra Costa County since 1989, and because our own 30-person crew handles framing, plumbing, electrical, and finish, your Walnut Creek project runs in sequence instead of stalling between subcontractors. Below are the four projects Walnut Creek homeowners ask us about most.

Autumn Drive — Home Addition & Pool
A completed home addition and pool on Autumn Drive in Walnut Creek, built by our own team from structure through finish. It’s the kind of addition-plus-outdoor-living work we handle across the city under a single contract.
Kitchen Remodeling
The closed-off galley kitchens common in Walnut Creek’s 1960s and 70s ranches are the single most-requested remodel we do here. We open plans to the family room, re-run plumbing and electrical to modern code, and rebuild from the subfloor up — cabinetry, counters, and finishes handled by the same team that framed the space. One crew means no gap between demo and finish.
Bathroom Remodeling
From compact hall baths to full primary-suite spa builds, bathroom remodels in older Walnut Creek homes almost always start with what’s behind the tile: aging supply lines, poor waterproofing, and undersized venting. We correct the systems first, then build the finished space, so the result lasts rather than looking good until the first leak.
ADU Construction
Whether it’s a detached backyard unit, a garage conversion, or a junior ADU inside the house, Walnut Creek lots are well suited to the extra unit — for rental income, family, or a home office. We handle the full path from site assessment and city permits through construction, sized to what your lot and setbacks actually allow under current California ADU law.
Home Additions
Adding a primary suite, expanding the kitchen, or bumping out the family room lets you gain space without leaving a neighborhood you’ve settled into. Every addition ties into the existing structure, so we start by confirming what the framing and foundation can carry — then build an addition that reads as original to the home, not bolted on.
Built for Walnut Creek homes and neighborhoods
Walnut Creek spans everything from the valley-floor neighborhoods near downtown to the foothill lots climbing toward Mount Diablo, and the right approach changes with the address. The mid-century ranches of Parkmead and Walnut Heights reward open-plan remodels and additions; the larger properties in Rudgear Estates and Northgate suit whole-home work and detached ADUs; and homes in the Saranap and Woodlands areas often need systems brought up to current code before any finish work makes sense.
As an incorporated city, Walnut Creek runs its own building and planning process, with its own submittal requirements, design standards, and inspection sequence. We’ve filed and built here for years, so the permit package goes in complete the first time rather than coming back as a correction letter. Rossmoor and other HOA communities add their own architectural review on top of city permits — something we plan for from the first drawing.

Walnut Creek general contractor questions
Yes. We prepare and submit the complete permit package to the City of Walnut Creek’s building and planning division, coordinate any required reviews, and manage the project through final inspection. You don’t handle submissions or corrections.
Most single-family lots in Walnut Creek qualify for at least one ADU under California law, and many can add a JADU as well. We confirm exactly what your lot, setbacks, and any HOA rules allow during a free site assessment.
Yes. Rossmoor and similar communities layer their own architectural review on top of city permits. We’ve worked within HOA design guidelines before and build that approval step into the schedule from the start.
A Walnut Creek kitchen typically runs several weeks once permits are in hand; a bathroom is shorter. Older homes can add time when we uncover outdated wiring or plumbing, which we document up front so there are no budget surprises.
Cost depends on scope, finish level, and what the existing home needs behind the walls. We document every line item — including any site or systems work — before the contract is signed, so the number you approve is the number you build to.
