We haven’t written Alameda’s permit guide yet.

We publish permit process guides one city at a time, and we would rather publish nothing than guess at Alameda’s rules using another city’s process. Permit steps, submittal requirements, and review timelines are set locally, so a guide copied from a neighboring city would be wrong in ways that cost you time.

Here is what is useful for Alameda right now.

What to ask the Alameda building department

  • The current building permit fee schedule, and the date it took effect.
  • Whether development impact fees apply at your square footage — many California cities waive them for ADUs of 750 sq ft or less.
  • Plan submittal requirements: what drawings they expect, in what format, and whether submittal is online or in person.
