San Francisco guide · Tier A · Rank #13 of 27
House hacking in San Francisco (Glen Park / Diamond Heights / Twin Peaks).
One strong, newly confirmed catalyst: the Family Zoning Plan rezones two lots immediately adjacent to Glen Park BART to 140 ft, with surrounding blocks at 6–8 stories, while most of the ZIP stays RH-1 outside that overlay.
Status check: Verified 2026-07-14: the Family Zoning Plan, signed into law Dec 12, 2025 and effective Jan 12, 2026, confirms two lots immediately adjacent to Glen Park BART at 140 ft with surrounding blocks at 6–8 stories. That resolves the metro doc's core uncertainty; no capital has landed yet (entitlement only). Tier moved B→A on that basis.

Most of the ZIP is RH-1 outside the FZP mid-rise overlay. Appreciation basis: Promoted B→A at the 2026-07-14 re-verification, after Section 8 froze; underwriting bands publish at the next full synthesis. Rent bands are city-level medians; confirm the specific parcel before trusting any of them. Run your own scenario in the calculator.
The house-hack angle
A corridor play: value concentrates on the two confirmed 140 ft BART-adjacent lots and the 6–8 story blocks around them, while the rest of the ZIP stays RH-1 single-family.
What breaks it
- The upzone is enacted but entitlement-only: no capital has landed yet
- Most of the ZIP is RH-1 outside the FZP mid-rise overlay
- No published Section 8 underwriting bands yet (promoted after the synthesis froze): underwrite from parcel-level comps
