Rent & eviction protection

Is 3930-3932 23Rd 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 1926

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 1926
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 3930-3932 23rd Street property is a two-story, three-unit multi-family residential building constructed in 1926 in Noe Valley, currently owned by the Marshall Family Trust 2003. The building has undergone several significant renovations and improvements in recent years, including window replacements in 2022, reroofing work in 2020, and multiple plumbing upgrades including a house trap/sewer replacement in 2018. Notable improvements include the installation of a fire sprinkler system in 2015-2016, electrical system upgrades with a new 100-amp service in 2016, and comprehensive remodeling of various units between 2013-2019, including kitchen and bathroom renovations, hallway updates, and front stucco replacement.

The property has experienced some regulatory scrutiny, most notably in 2019 when a complaint was filed regarding an allegedly unauthorized dwelling unit in the basement, resulting in multiple housing code violations related to change of use, egress, fire protection, electrical, plumbing, and mechanical systems. This issue was officially abated in November 2019. The building's infrastructure maintenance has shown attention to fire safety and modernization needs, including a new water meter for the fire sprinkler system and various plumbing and electrical improvements. Recent maintenance issues have included multiple sewer backup incidents in September 2020, though these were resolved through city work orders. The property has had several historical building complaints regarding unauthorized work and modifications, though most of these issues appear to have been addressed, with the exception of some open pavement defect reports from 2024. Recent exterior maintenance includes window upgrades and various systems improvements, suggesting ongoing investment in the building's infrastructure and safety systems.

Risk rating

How 3930-3932 23Rd 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
50thpercentile

Out of 1879 buildings in this neighborhood, 940 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
