Building for Concord homes, the right way
Concord is Contra Costa’s largest city, with a housing stock built largely from the 1950s through the 1970s — solid postwar and mid-century homes on generous, mostly flat valley lots. That combination is exactly why so many Concord homeowners remodel, add on, or build an ADU rather than move: the lots have room, and the homes are ready for an update. Rhino Builders has built across Contra Costa since 1989, and we self-perform every trade, so nothing critical gets subcontracted away. These are the four projects Concord homeowners ask about most.
Custom Home Builder
Concord’s larger valley lots are prime ground for ground-up custom homes and full tear-down rebuilds. We engineer the foundation to the soils report, design drainage the city will approve, and detail the structure for Concord’s hot inland climate and energy code. Architecture, permitting, and construction stay under one roof, so the vision that’s drawn is the home that gets built.
Home Additions
Many Concord families love their neighborhood but have outgrown a 1960s floor plan. A well-designed addition — a primary suite, an expanded kitchen, a second story — adds space without giving up the location or the lot. The structural tie-in to an older home is where additions succeed or fail, so we scope the framing and foundation before the finishes and build an addition that reads as part of the original house.
ADU Construction
Concord’s deeper lots make it one of the best cities in the county for a detached ADU — for extended family, rental income, or a private studio. The make-or-break details are setbacks, utility runs, and how the unit sits relative to the main home. We assess the buildable envelope, then handle design, city permits, and construction as one process from ground clearing to final sign-off.
Kitchen Remodeling
Concord’s mid-century homes are full of closed-off, dated kitchens walled away from the living space. We open those layouts up, bring wiring and plumbing up to current code, and rebuild with durable, modern finishes — all self-performed, so demo, rough-in, and finish flow as one schedule instead of stalling between trades.
Mid-century homes, valley lots, and room to grow
Concord’s neighborhoods — Todos Santos and the downtown core, Dana Estates, Ygnacio Valley, Clayton Valley, and Turtle Creek — share the same practical traits: mostly flat, generously sized lots and homes built largely between the 1950s and 1970s. Building or remodeling here usually means working with aging framing, original electrical panels, and galvanized or cast-iron plumbing that’s reached the end of its life. Knowing what’s behind the walls of a Concord home before demo is what keeps a project on budget.
Concord’s hot, dry inland summers also shape the work: HVAC sizing, insulation, and energy compliance under Title 24 matter more here than in the cooler coastal cities. Where a property backs up to the Lime Ridge or Mount Diablo foothills, some fire-zone detailing can apply, and we check that during design. As its own city, Concord runs its permits through the Concord Building Division, and we build that review timeline into the schedule from day one.

Concord construction questions
Much of Concord was built between the 1950s and 1970s, so most projects involve aging framing, original electrical service, and older plumbing. That’s not a problem — it just means the smart move is assessing what’s behind the walls before demo, so upgrades are planned and priced up front instead of becoming surprises mid-build.
Most of Concord’s valley neighborhoods are not in elevated fire zones, unlike the surrounding hillside cities. Properties near the Lime Ridge Open Space or the Mount Diablo foothills can carry some fire-zone requirements, which affect exterior materials and clearances. We confirm your parcel’s designation during design so nothing surfaces at plan check.
Yes. Concord runs permits through its own Building Division. We prepare the complete package, respond to plan-check comments, and manage inspections through final sign-off so you’re never chasing the city yourself.
Usually, yes — Concord’s lots tend to be deeper and flatter than the surrounding hillside cities, which makes detached ADUs very feasible. The deciding factors are setbacks, existing coverage, and utility routing. We check the buildable envelope during the site visit and design the unit to fit it.
It depends on the condition of the existing structure and how much you want to change. If the framing and foundation are sound, a remodel or addition is often the better value. When bringing an older home fully up to code approaches the cost of building new, a rebuild can make more sense. We give you an honest comparison before you commit.
