Permitting & Local Notes for Lafayette
Lafayette’s own Planning Department reviews your project for zoning and design compliance, but the City contracts building permit plan-check and inspection out to the Contra Costa County Building Inspection Department — so a Lafayette bathroom remodel touches two agencies, not one. We’ve navigated Lafayette’s FAR and attached room threshold questions on past projects, which matters if your bathroom remodel is part of a larger addition rather than a same-footprint refresh.

Do I need a permit to remodel a bathroom in Lafayette?
Many bathroom remodels require permits, particularly when plumbing, electrical, windows, walls, or other building components are being modified. Permit requirements depend on the scope of work, so we determine what is required for each project during the planning process. If a project does require a permit it will be reviewed by the City and processed through Contra Costa County’s building inspection division.
Why Lafayette Homeowners Work With Us
We design every project with an architect and engineer on the team from day one, which matters in Lafayette given how many homes here have non-standard layouts or hillside lots that trigger structural questions early. As both your designer and your project manager, we protect your budget from the first sketch through the final walkthrough — no surprise change orders because a wall turned out to be load-bearing.
