Because we work in Contra Costa County every week, we know how this city reviews plans and what its inspectors look for. That is usually the difference between a project that starts on schedule and one that sits waiting on corrections.

What We Build in San Ramon

  • Kitchen remodeling in San Ramon — layout changes, cabinetry, counters, lighting and the electrical and plumbing work behind them
  • Bathroom remodeling — primary suites, hall baths, walk-in showers, tile and waterproofing
  • Whole-home renovations — one contractor and one contract from demolition through final inspection
  • Home additions — bedroom and family room expansions, second stories and structural changes
  • ADUs — detached and attached accessory dwelling units, including garage conversions

Permits and Plan Review in San Ramon

Our office is at 2603 Camino Ramon, Suite 200, and we are in front of San Ramon’s Building and Safety Services regularly. Permit applications go through the city’s Citizen Self Service portal and take about 5 to 10 business days just to process.

Once processed, your application is routed to three separate divisions: Planning for zoning compliance and architectural review, Building and Safety for building code, and Engineering for engineering code. Plan check fees must be paid before review begins. Reviewers generally return comments within about 10 business days of routing, and the permit issues once comments are addressed and remaining fees are paid. Building and Safety Services can be reached at (925) 973-2500.

What that means for your project

Two things catch San Ramon homeowners off guard. First, the three-division routing means a comment from any one of Planning, Building or Engineering stalls the whole permit — so the submittal needs to be complete on all three fronts the first time. Second, the city does not enforce HOA standards, which means it will happily issue you a permit for something your association will later reject. Get HOA approval in parallel, not afterward.

Neighborhoods We Serve in San Ramon

We work throughout San Ramon, including Dougherty Valley, Gale Ranch, Windemere, Twin Creeks, Country Club and the neighborhoods around Bishop Ranch.

San Ramon covers a wide age range. The neighborhoods built from the 1970s through the 1990s are the ones most often due for kitchen, bath and whole-home work, while Dougherty Valley’s 2000s construction is newer but heavily governed by HOA design standards. In practice, a San Ramon remodel usually involves two approvals, not one: the city’s and your homeowners association’s.

Frequently Asked Questions

Do I need a permit to remodel my kitchen or bathroom in San Ramon?

Yes, for anything structural, electrical, plumbing or mechanical, and for layout changes. San Ramon routes residential permits through Planning, Building and Safety, and Engineering, so plan on a complete submittal rather than a partial one.

How long does plan review take in San Ramon?

Expect about 5 to 10 business days just to process the application, then roughly 10 business days from routing for reviewer comments. Addressing comments and paying remaining fees follows before the permit issues.

Do you handle the permit process for me?

Yes. We prepare the submittal, file with the City of San Ramon Building and Safety Services, respond to plan check comments and schedule every inspection through final. You are not the one calling the city.
