Rent & eviction protection

Is 3233-3235 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.

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 1924
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 residential building at 3233-3235 23rd Street, owned by Gerald Lee and Lok Yan Yu, has undergone several significant renovations and faced various challenges since its construction in 1924. Most notably, in recent years, the property experienced substantial improvements in 2021, including a comprehensive window replacement project ($8,500) at both the front and rear of the building, and a kitchen and bathroom remodel ($60,000) that included electrical and plumbing upgrades, completed in early 2021. The building faced serious issues in 2015, with multiple violations including mold/mildew, rodent infestation, water damage, and safety concerns regarding a fixed utility ladder, all of which were officially abated by February 2020. These violations also included fire safety concerns regarding garbage receptacles and combustible materials, though follow-up inspections indicated these conditions were corrected. A tenant buyout occurred in November 2021, involving three tenants and amounting to $35,000.

The property has a history of maintenance activity including two roofing projects (1989 and 2010) and a notable complaint regarding unsafe heating and plumbing fixtures dating back to 1995, though these issues were resolved by 1998. More recently, there has been one active electrical work without permit complaint from February 2021. The building's surroundings have faced various urban challenges, as evidenced by multiple recent 311 calls in 2023-2024 regarding garbage and debris, driveway blocking, and an encampment report. These external issues, while not directly related to the building's condition, may impact the resident experience. The property's maintenance history shows a pattern of addressing violations and undertaking significant improvements, particularly in recent years, with particular attention paid to window upgrades and interior modernization.

Risk rating

How 3233-3235 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
91stpercentile

Out of 2380 buildings in this neighborhood, 214 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
