Safer Bathroom in Castro Valley: Free In-Home Consultation
Permits from Alameda County
Castro Valley is unincorporated, so Alameda County, not a city, issues your building permit. That affects where you apply and who you call, though not what makes a bathroom safer. Here is a plain guide for Castro Valley homeowners.
The Alameda County Building Department, part of the Public Works Agency, issues building permits for unincorporated areas including Castro Valley, Ashland and San Lorenzo. Permit records are searchable on the Alameda County Permit Portal at permit.acgov.org. The county’s information center lists documents on work exempt from permit, plan requirements for small projects and residential CO and smoke alarms. The county notes its pages may not reflect current adopted codes, so confirm details with staff at 510-670-5440.
Moving plumbing, changing a shower pan, adding circuits or altering framing is typically permit work. California Civil Code 1101.4 also requires water-conserving fixtures on single-family alterations. Axiom handles the submittal.
How a curbless shower is built, step by step
Thinking about a step-free shower for your Castro Valley home? Here is what happens under the tile, from the old curb to the finished shower. Press Play to watch each step, or tap one. Switch between a concrete slab and a wood-framed floor.

A bathroom that supports daily life
Strong aging-in-place bathrooms share a few features: grab bars anchored to blocking, a shower with a low or no threshold, a bench, a handheld shower and a comfort-height toilet. The 2010 ADA Standards put grab bars at 33 to 36 inches above the floor and seats at 17 to 19 inches. Those rules bind public buildings. At home they are a proven reference. Read the aging-in-place bathroom guide for details, and ask an occupational therapist (OT) to assess needs.
Recent Axiom walk-in showers
Bathrooms recently built by Axiom Renovation: walk-in showers with low curbs or open entries, linear drains, handheld showers and a built-in bench.
Checking an older home first
The county’s lead hazard repair grants target pre-1960 housing in Alameda County, a reminder that older bathrooms may hide old pipes, paint and framing surprises. Before a curbless shower we look at the floor structure. A raised wood floor can be recessed between joists, and a slab may need cutting. We also walk the path from the bedroom to the bathroom to spot thresholds and tight turns.
