Rent & eviction protection

Is 1231-1233 46Th Ave 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 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 2-unit, 2-story multi-family residential building at 1231 46th Avenue in San Francisco's Outer Sunset district was built in 1904 and is currently owned by Sera Lo LLC. The building's documented history reveals several significant events, particularly related to safety and structural concerns. In early 1996, the property experienced fire damage that required inspection and subsequent repair work, including replacement of front siding with stucco and repairs to the front stairs. In 2009, a routine safety inspection identified the need for fire extinguishers, which was promptly addressed within two weeks. That same year, there was a complaint about unauthorized construction, specifically regarding a 20-foot rear extension and a possible illegal unit, though the status of this complaint is listed as not active.

The building has undergone several routine inspections over the years (1999, 2002, and 2009), showing consistent oversight by housing authorities. More recent history of the property primarily involves external issues documented through 311 calls, mostly relating to parking concerns (abandoned vehicles and blocked driveways) between 2018-2019, as well as some street maintenance matters like graffiti and waste removal requests in 2014 and 2012. The most pressing historical concerns appear to be the 1996 fire incident and the 2009 fire safety compliance issue, both of which were resolved. The building's permit history shows record-keeping dating back to 1982, though details of the 1982 permit are not specified in the provided data.

Risk rating

How 1231-1233 46Th Ave'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
46thpercentile

Out of 632 buildings in this neighborhood, 341 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 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.

Neighborhood (ZIP code)

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