Rent & eviction protection

Is 4234-4236 Mission 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 before 1979
Built 1933

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 1933
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-unit, two-story multi-family residential building at 4234-4236 Mission Street, constructed in 1933, has experienced several significant maintenance and safety issues over the past decade, with the most critical events occurring between 2017-2018. During this period, the property faced multiple housing violations including rodent infestation, security concerns related to windows and doors, plumbing issues, and problems with smoke and carbon monoxide detectors, all of which were abated by September 2017. The building underwent multiple repairs and improvements, including a bathroom renovation in 2018 that involved window replacement, flooring updates, and installation of ADA signage, though there were initial concerns about the lack of proper permits for interior work. Electrical safety was addressed through several permits, with work completed in 2014 to correct various electrical code violations including emergency lighting, stage lights, and GFCI installations. The property has had four documented fire department responses between 2017-2018, all related to smoke detector activations with no fires or injuries reported.

Historical records indicate various maintenance work over the years, including sidewalk repairs, roofing in 1995, front glass repairs in 1985, and more recent plumbing work in 2013. The building had some structural concerns in 2010 regarding rear stairs that required repair, and there were issues related to an electric sign installation in 2017 that prompted code enforcement action. More recent activity at the property includes several 311 calls between 2021-2024, primarily related to parking enforcement and street maintenance, though these are not directly related to building conditions or safety.

Risk rating

How 4234-4236 Mission 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
72ndpercentile

Out of 149 buildings in this neighborhood, 42 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
