LOCAL RESEARCH / East Palo Alto
Building history
The present city included Ravenswood and North Palo Alto in the early twentieth century, but did not incorporate until 1983.
Source ↗Local context
Its small, centrally located area sits near San Francisco Bay and major transport links, so commercial and residential calls can be close together.
Source ↗Planning your work
In San Mateo County's incorporated cities the building department for the city that covers the address is the permitting authority, not the county. The Contractors State License Board's consumer page on building permits states the California Building Standards Code position that work may not be erected, altered, repaired or demolished without a permit first obtained from the building official, notes that code requirements vary between cities and counties, and asks readers to check with their local building department. Confirm the scope with that department before work is arranged.
Source ↗Area-wide context does not establish the condition of your property or equipment.
Before the visit
Identify the affected opening and describe the symptom. Gather available product labels and previous work records. Explain access restrictions and keep the opening clear.
