24 HOURS · THE EAST BAY

Castro Valley is not a city. So what?

Castro Valley is unincorporated Alameda County, so there is no city hall to walk into. Permits come from the county and the sewer from Castro Valley Sanitary District. That changes who signs, who you call, and how long it takes.

Two counties. One crew. No waiting.

Somebody answers and a van leaves. Looking is on us. CSLB #1131134 · IICRC #70194273

Why does that matter at all?

Because half the instructions online send you nowhere.

Call your city, check with city hall, ask the city inspector. None of those exist here.

The county counter answers instead, and it runs its own hours and its own forms.

Getting that wrong costs a day, and sometimes a wasted trip.

Who issues a permit here?

Alameda County, not a city building department.

Castro Valley sits in unincorporated county territory.

So the exemption list, the plan check queue and the inspection card are the county’s.

Nothing a neighboring city publishes about drywall or roofing applies to this ground.

What about the sewer?

Castro Valley Sanitary District, its own agency.

Not the city, because there is no city, and not the county either.

It is one of seven sewer agencies across the twenty-four cities on this list.

Your bill names yours, and that is the fastest way to be sure.

Does this change the drying?

Not one reading. Water behaves the same anywhere.

Extraction, air movers and a dehumidifier run the night it happens.

Meters decide when the equipment leaves, not a counter and not a calendar.

The paperwork side is where the address starts to matter.

When does it start mattering?

The moment a wall has to be closed again.

Putting the same wall back in the same place is the simple case.

Anything structural, or a change in layout, puts the county in the room.

Ask which counter before anybody quotes you a schedule.

Does the house age matter here?

As much as anywhere, and the sampling rules travel.

A house finished before the lead and asbestos lines gets a sample before a saw.

That rule is state and federal, so no county line changes it.

What the county changes is who issues the demolition permit afterward.

What should I never write?

The City of Castro Valley. It does not exist.

It sounds pedantic until somebody sends a contractor to a counter that is not there.

The same care applies to who owns the pipe in the street.

Naming the right agency is not decoration. It is the difference between a call and a day.

What does it cost to look?

Nothing, here as everywhere else on this list.

Somebody drives out, reads the walls, and says which material is actually wet.

Drying starts at $61 an hour once the crew begins.

The rebuild is a written total, never a figure on a page.

What is not ours to decide?

The county’s signature, and what a lab reads.

The application, the corrections and the inspection day are on us.

Our numbers are CSLB #1131134 and IICRC #70194273, both public.

Unincorporated ground throws up more than this; see the guides.

Which East Bay Cities Actually Flood, and Which Do Not

Antioch floods in two named streets, Pinole Creek has done it for over a century, and Brentwood has no known principal flood problem. Naming which is the point.

Sixty percent of Alameda’s shallow groundwater already sits near the surface, so damp arrives from underneath. How to tell that from a leak, and what it changes.

Ask which counter before anybody quotes you a schedule. (341) 220-0032 and somebody reads the walls first.
