Custom Home Additions in Concord, CA
A custom home addition in Concord usually means building out, not up. The postwar subdivisions off Clayton Road and through Ygnacio Valley were platted with generous rear yards, so a bedroom wing or a great room extension often fits inside the setbacks without touching the roofline. Where the lot is tight or the view matters, a second story becomes the option worth drawing.
The old house is the part that surprises people. A 1958 tract home was framed for a smaller electrical service, thinner insulation and a furnace sized for the square footage it had. Tie 500 new feet onto it and the panel, ducting and Title 24 energy numbers all get looked at. TRD Pros works that into the design instead of finding it after demolition.
Why Concord Homeowners Choose TRD Pros
We keep an office on Shary Circle in Concord and a second one on Mount Diablo Boulevard in Walnut Creek. Site visits stay easy to schedule.
Talk Through Your Concord Addition
Call (925) 510-2888 to walk your lot and find out what your house can realistically take on.
Permits and Inspections Handled
We prepare and file the permit application, then coordinate the inspections as the addition moves from foundation to final sign-off.
Written Schedule Before Demo
You get a written schedule before demolition starts, so you know the order of work before your house is opened up.
Remodel Versus Addition, Priced
During design we price a remodel inside your existing footprint alongside the addition. You compare two real numbers before committing.
Much of Concord is single-story tract housing from the 1950s and 60s, sitting on lots with real back yard depth. That makes a ground-floor addition the practical way to add a bedroom, a family room or a primary suite.
We Run The Permit
Additions need plan review and a string of inspections. We handle the application and coordinate the inspectors, so you are not tracking that yourself.
Design And Build Together
Design and build work under one contract, with color match and paint selection in-house, so new stucco and trim read as part of the original house.
Concord Addition Questions
Do I need a permit to build a home addition in Concord?
Yes. Any addition to a house in Concord requires a building permit from the city, with stamped plans, structural details and California Title 24 energy compliance. Zoning gets checked too: setbacks, lot coverage and height for your district. TRD Pros prepares and files the permit application and coordinates the inspections as construction progresses. Plan review takes time, so treat permitting as part of the project calendar, not a formality at the end of design.
Is it better to build out into the yard or add a second story?
In Concord, building out is usually simpler. The older subdivisions here have deep rear yards, and a single-story addition avoids re-engineering the existing foundation and walls to carry a new floor. Building out does eat yard and is limited by setbacks and lot coverage. A second story makes sense on a narrow lot, or when you want to keep the garden and the Mount Diablo sightline. We draw both when the lot allows it.
What drives the cost of an addition on an older Concord home?
The condition of the existing house drives it more than the new square footage. Homes from the 1950s and 60s often need a larger electrical panel, plumbing updates, and heating and cooling capacity that can handle Concord’s hot inland summers across a bigger floor plan. Foundation work, roof tie-ins and side-yard access for equipment all move the number. Matching original stucco, siding and trim is a smaller line, but it is what makes the addition look right.
Would remodeling what I already have be cheaper than adding on?
Often, yes, and it is worth checking before you commit. Many Concord ranch homes have compartmented kitchens, a formal dining room nobody uses and a long hallway soaking up floor area. Opening that up can deliver the space you wanted without new foundation or roof. During design we price both a remodel inside the existing footprint and the addition, so the comparison is real numbers rather than guesswork.
Do I need HOA approval as well as a city permit?
Only if your Concord neighborhood has one. The older tract areas around downtown and Clayton Valley generally do not, while newer developments and attached-housing communities often do, with rules on rooflines, exterior color and how far you can build back. Check your CC&Rs early. Board review runs on its own timetable, and submitting to the HOA while city plan review is underway keeps the two from stacking up.
We build additions across central Contra Costa: Concord, Pleasant Hill, Martinez, Walnut Creek and Lafayette, along with Alamo, Danville, Orinda, Moraga and San Ramon. If you have outgrown a Concord ranch house and want to know what the lot and the existing structure can support, call (925) 510-2888 or email info@topremodelingdesign.com to set up an estimate.
