Rent & eviction protection

Is 542 25Th 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.

Built 1923

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.

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-story, 4-unit multi-family residential building at 542 25th Avenue in the Central Richmond neighborhood, owned by Ko Family Trust, has experienced several significant maintenance and safety issues over its history since being built in 1923. Most notably, in 2003, the building underwent a series of fire safety violations that were promptly addressed and abated, including issues with egress obstruction, combustible storage, and the need for fire sprinklers, though these violations highlighted past safety concerns. The building has seen regular maintenance and improvements, including a $12,450 reroofing project in 2017, multiple bathroom and storage room modifications in the late 1990s, and significant upgrades in 1991 including the installation of new windows and a garage door.

Recent maintenance issues have primarily centered around plumbing problems, with four documented sewage backup incidents between 2020 and 2022, suggesting ongoing infrastructure challenges. A more recent concern emerged in January 2024 regarding mold and mildew, though this was transferred to the Department of Public Health for further investigation. The building's history also includes one instance of an illegally converted garage into an auto repair shop in 2005, though this situation was resolved. While the property has generally shown responsiveness to violations and maintenance needs, the recurring sewer issues and more recent mold complaint indicate potential ongoing maintenance challenges. The most recent documented issue pertains to a parking enforcement matter in August 2024, though this was ultimately deemed invalid by authorities.

Risk rating

How 542 25Th 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
31stpercentile

Out of 2250 buildings in this neighborhood, 1552 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
