West Covina no longer takes applications by email, which catches out anyone working from old notes.
The West Covina Building Division is no longer accepting applications via email. Small change, real consequence: an application sent the old way is not in a queue, it is nowhere, and nobody finds out until someone chases it. We file the current way.
The city has 34,834 housing units with about 60 percent owner occupied, in a San Gabriel Valley climate where summer temperatures average above 23 degrees Celsius. That sustained inland heat is what works a deck surface loose at the edges over a season, well before any rain gets the chance to exploit it.
