LOCAL RESEARCH / South San Francisco
Building history
South San Francisco was incorporated in 1908, placing much of its original civic development in the Peninsula's streetcar-era growth period.
Source ↗Local exposure
The air district’s 2011 regional climate description identifies the low San Bruno Gap as a route for marine air to enter the bay. Wind patterns vary by location; this description is not an assessment of an individual opening or component.
Source ↗Planning your work
South San Francisco's Building Division states that any building or structure to be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished requires a building permit. It adds that while the codes may exempt certain work from permit requirements, electrical, plumbing or mechanical work must still be permitted, and asks readers to check with the Planning Division as well. Confirm the scope with the city before work is arranged; this reference does not establish what your property requires.
