Rent & eviction protection

Is 15 Harriet 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.

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.

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

15 Harriet Street is a 3-unit multi-family residential building constructed in 1921, currently owned by Big Three LLC and located in San Francisco's South of Market neighborhood. The building's maintenance history includes several significant events, with the most pressing issues occurring recently in 2024-2025, including multiple fire safety concerns involving blocked exits (three separate incidents in 2024). The property has experienced recurring encampment issues in the surrounding area, with numerous reports in late 2024 and early 2025, though many were resolved through cleanup efforts. A concerning history of fire-related incidents is documented, including three fire complaints in 2020-2024 related to exit maintenance and security systems, and multiple violations between 2018-2020 concerning exits, sprinklers, and storage of combustible materials.

The building's repair history shows attention to maintenance, including a roofing project in 2009 and interior repairs in 2016 following a roof leak, though this work came in response to a complaint about unauthorized work hours. An illegal unit complaint from 1997 alleged unsafe living conditions, though there is no record of this issue persisting. Recent municipal records indicate infrastructure concerns in the vicinity, including a collapsed sidewalk reported in January 2025. While the building has undergone various repairs and maintenance work, the recurring nature of exit blockage violations and recent infrastructural issues in the immediate vicinity are noteworthy.

Risk rating

How 15 Harriet 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
71stpercentile

Out of 430 buildings in this neighborhood, 125 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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

Building age

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