Rent & eviction protection

Is 1243 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.

Built 1910

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 1910
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 1243 23rd Avenue property is a two-story, multi-family residential building located in San Francisco's Central Sunset neighborhood, containing three units and owned by Fei Yuming & Ye Ziqi. Built in 1910, the building underwent significant modifications in the mid-1990s, including a completed horizontal addition in 1994 costing $71,000, and subsequent improvements to parking space and a heating room in 1996. A notable building complaint from November 1994 reported a potentially hazardous situation regarding an unauthorized rental unit in the garage, lacking proper ventilation and emergency egress, though this issue was marked as abated by January 1995.

In more recent years, the property has experienced numerous parking-related incidents, with seven documented cases of driveway blocking or sidewalk parking between 2022 and 2024, though most citations were either unable to locate the offending vehicle or resulted in a citation being issued. There were also two minor fire-related incidents recorded: a gas leak and a carbon monoxide detector activation, neither resulting in civilian injuries. Additional quality-of-life issues included complaints about waste receptacles being left out continuously (July 2022) and a graffiti incident (February 2019). The building's age and history of unauthorized modifications suggest some ongoing maintenance challenges, while the concentration of parking enforcement issues indicates ongoing challenges with parking management in the immediate vicinity.

Risk rating

How 1243 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
18thpercentile

Out of 814 buildings in this neighborhood, 667 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

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