Rent & eviction protection

Is 271-273 23Rd 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 1925
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 property at 271 23rd Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1925 and currently owned by the Ada Y Hom 1991 Living Trust, this flats/duplex-style building has undergone several significant improvements in recent years. Most notably, between 2023 and 2024, the building received substantial window and roof upgrades, including the replacement of multiple windows with energy-efficient retrofit options, costing approximately $28,430 in 2023, followed by a revision in 2024 that modified the scope to include 11 windows with aluminum wood-clad materials. The building also received a new roof in March 2024, with the roofing work valued at $16,000. Historical records show an earlier roofing project completed in 1992.

The property has been subject to various municipal service calls over the past few years, primarily related to street and sidewalk maintenance issues. The most recent concerns include a pavement defect reported in August 2024 and two instances of human or animal waste removal in 2022. There have been several parking-related incidents in the vicinity, including two cases of driveway blocking in 2024 and 2021. The building's surroundings have experienced typical urban maintenance issues, as evidenced by multiple street cleaning calls, including responses to general cleaning needs, overflowing garbage cans, and one Christmas tree removal request in early 2023. While these external issues don't directly impact the building's structural integrity, they do provide context about the immediate neighborhood environment.

Risk rating

How 271-273 23Rd 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
95thpercentile

Out of 2250 buildings in this neighborhood, 112 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.

Director's hearings, owner's portfolio

Escalated DBI enforcement actions across all of this owner's buildings.
