Concord’s established inland neighborhoods offer a range of garage and backyard configurations. We compare reuse of an existing structure with new construction and check the site against the city’s ADU guidance.
Working with established Concord homes
In neighborhoods such as Dana Estates and around older central Concord streets, the garage location and backyard depth are useful starting points. We measure access, locate sewer and electrical services and identify whether a conversion would preserve more yard than a detached unit.
Near Todos Santos Plaza, established buildings and tighter site arrangements can make placement and privacy important. We plan windows, outdoor space and the route to the ADU around the existing home rather than treating the backyard as an empty rectangle.
Using Concord’s pre-approved-plan resources
Concord publishes free pre-approved ADU plans and a site-plan template. A standard plan can be worth considering, but the parcel still needs its own placement, utility and permit review. For an existing unpermitted unit, we ask the city about the applicable legalization process before recommending a scope.
How much does an ADU cost in Concord?
Costs in the Bay Area are often higher than in the Sacramento Valley because of labor, permitting and site conditions. Call us for a number based on your property. See costs and financing for Sacramento reference ranges and financing options, not a Bay Area quote.
Rules vary by city. Call us to confirm what applies to your property.
Can Concord’s free ADU plans replace a site plan?
No. Concord’s plan resources include a site-plan template because each property still needs its own placement and service information.
Can you help assess an existing unpermitted Concord unit?
We can review the structure and discuss the city’s legalization resources. Approval and the required upgrades depend on the existing conditions and current city review.
