Rent & eviction protection

Is 1512 20Th St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built 1900

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Built 1900
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

1512 20th Street is a two-story multi-family residential building located in San Francisco's Potrero Hill neighborhood, owned by Hudaharrah Holdings and constructed in 1900. The property underwent significant proposed renovations in 2013, which included removing the existing roof, increasing building height, adding a new mezzanine, constructing a roof deck, and rehabilitating the front facade with new windows and updated garage doors, with an estimated cost of $500,000. However, in August 2019, this project was revised to reduce its scope by eliminating the mezzanine and modifying the front facade, though this revision was ultimately cancelled.

The building's recent history shows consistent attention to parking enforcement and sign maintenance, with multiple reports of defaced parking signs (2018-2023) and two incidents of parking violations in 2023. A 2019 report documented an overgrown tree blocking the sidewalk, which was addressed by San Francisco Public Works. The property has a documented history of being unoccupied for over 30 years prior to the proposed renovations, during which it fell into a state of disrepair, though specific details about its current occupancy status are not available in the provided records. The building's permitting and planning records indicate a complex history of proposed improvements, with discretionary review processes resulting in some modifications to the original plans.

Risk rating

How 1512 20Th St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
75thpercentile

Out of 726 buildings in this neighborhood, 182 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
