The Portola was San Francisco's growing district long before it was a residential one. Commercial greenhouses and nurseries covered these slopes for decades, supplying flowers to the city, and a few of the old glasshouses still stand along San Bruno Avenue.
That history left something unusual behind: lots that are deeper than almost anywhere else in San Francisco. When the nurseries gave way to housing in the 1930s and 40s, the parcels kept their generous dimensions, and the houses that went up on them are detached, single-family, and set back with real yards front and rear.
For a remodeler that is close to ideal. Detached houses with driveways, deep rear yards, and no party walls — the practical constraints that shape a project in the northern districts simply are not here.
The Portola's lot depths make it arguably the strongest ADU neighbourhood in San Francisco. Where a Noe Valley or Castro rear yard is a measuring exercise against setbacks, a Portola rear yard frequently has room for a real detached unit with its own outdoor space and usable garden left over.
Many properties also still have outbuildings — old sheds, garages, and in a few cases former nursery structures — which can sometimes be converted rather than replaced, saving the cost of a new shell.
State law requires ministerial review within 60 days for ADUs meeting objective standards. San Francisco's rear-yard setback rules still apply, so establishing the buildable depth before design is worth the short check it takes.
These are solid, straightforward houses — wood-framed, conventionally built, and largely free of the century-old systems questions that dominate work in the pre-1906 neighbourhoods. The framing is sound and the layouts are simple.
What dates them is the era: a kitchen closed off from the living space, one or two bathrooms, original single-pane windows, and minimal insulation. Electrical service sized for a 1940s household is frequently the gating item before a modern kitchen.
Permits run through San Francisco's citywide Department of Building Inspection — the Portola has no building department of its own.
