How this market compares
San Carlos against every other city in California on the same measure. City figures cover the ZIP codes assigned to the place rather than its municipal boundary, so they are compared as a share of the businesses in those same ZIP codes rather than per resident. Cities with fewer than 500 businesses in total are left unranked.
About the same slice of the local business base as the industry holds statewide.

What acquirers look at
Storm-driven revenue is lumpy and insurance-dependent; recurring commercial maintenance contracts are the durable part. Diligence should isolate re-roof versus repair mix.
