Rent & eviction protection

Is 19-21 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.

15+ years since occupancy
Built 1912
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

The 3-story multi-family residential building at 19-21 Harriet Street in San Francisco's South of Market neighborhood, owned by Robert & Mireya Wall Fmly T, was constructed in 1912 and contains 6 units. The property has undergone several significant structural improvements over the years, most notably completing a required soft-story retrofit in 2018 at a cost of $45,000 to enhance seismic safety. Recent maintenance work includes a house trap replacement in 2022, demonstrating ongoing infrastructure upkeep. The building underwent comprehensive renovations in 1992, including foundation upgrades with grade beam installation, unit remodeling, and electrical system improvements.

The property has faced several safety and maintenance challenges, particularly during a health and safety inspection in 2007 that resulted in multiple violations, including issues with wood stairs, fire safety equipment, smoke detectors, and security features - all of which were subsequently abated by January 2008. Earlier concerns were documented in 1995 regarding inadequate security. More recent history shows a pattern of encampment-related issues in the immediate vicinity, with multiple reports in 2024, though these are external to the building itself. The building's maintenance record shows attention to both immediate repairs and larger structural improvements, including historical work from the 1980s and early 1990s that addressed various building systems. The property has maintained its compliance with major regulatory requirements, as evidenced by the completed soft-story retrofit and other permitted improvements.

Risk rating

How 19-21 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
73rdpercentile

Out of 430 buildings in this neighborhood, 116 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
