Rent & eviction protection

Is 4105-4121 19Th 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.

Built 1904
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 two-story multi-family residential building at 4105-4121 19th Street, owned by the Boyd M Swartz Revc Trust, was constructed in 1904 and contains 9 units, plus commercial space. The property has recently undergone barrier remediation work in September 2023, with permits filed to install accessibility features including signage and a buzzer system. These improvements were required to address ABE compliance. The building's history includes several notable events: in 1983, the residential space was converted to office use, and there was a significant plumbing infrastructure upgrade in 2013 involving the replacement of the building's house trap and sidewalk sewer lines. Two housing inspection complaints were filed in 1994 regarding unauthorized commercial use of residential units, though these were resolved within a month of filing.

The property has experienced recurring issues with street cleanliness and garbage management in recent years, particularly throughout 2024, with multiple 311 calls regarding loose garbage, debris, and waste management. These include eight separate reports of general cleaning concerns and one instance of toters being left out continuously, with varying outcomes from resolved cases to one currently open case (as of May 2024). While these sanitation issues primarily relate to exterior maintenance rather than building conditions, they may affect resident comfort in common areas. The building's commercial space has been home to several notable businesses, including Yankee Clipper Travel and Castro Village Wine Company, and has undergone various improvements and permits for business-related changes, such as the installation of an assistance buzzer and signage for ABE compliance.

Risk rating

How 4105-4121 19Th 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
10thpercentile

Out of 1278 buildings in this neighborhood, 1150 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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.
