Alameda County has named unincorporated communities to check first
Alameda County names several unincorporated communities: Ashland, Castro Valley, Cherryland, Fairview, Hayward Acres, San Lorenzo, and Sunol. The county also has a locator. It helps you check whether you live in one.
Start there. If the place is one of those communities, or rural east county outside a city, check the county planning page first. A city office may not be the right first stop.

California Porch explains the path. The official source is still the place to confirm the current rule, fee, form, map, deadline, or office decision.
Use the official page before you spend money, file paperwork, rely on a deadline, or change a property.
