Rent & eviction protection

Is 1401 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 1948

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 1948
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 1401 25th Avenue in the Central Sunset neighborhood is a two-story flats/duplex structure built in 1948, currently owned by Reginald David Wong. The building's documented history shows several significant improvements made over the years to enhance safety and functionality. In 2004, fire sprinklers were professionally installed, and in 2003, window security measures were implemented, including the installation of window guards and a security gate. The ground floor underwent substantial modifications in the early 2000s, transitioning from a computer room to a bedroom, along with the addition of laundry facilities and a full bath in 2001. More recently, there was an attempted installation of solar panels in 2015, though this permit was ultimately cancelled.

The property has experienced some ongoing maintenance challenges, particularly in late 2024 and early 2025, with multiple reports (at least 12 cases) of garbage and debris issues near the property, though most of these were resolved with no further action required. A notable housing complaint was filed in November 2021 regarding uncleaned garbage cans potentially attracting rodents, though this case is currently listed as not active. The building's permit history suggests a pattern of improvements focused on safety and modernization, with most recent activity indicating both regular maintenance issues and environmental sustainability efforts, despite the cancelled solar panel installation.

Risk rating

How 1401 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
20thpercentile

Out of 814 buildings in this neighborhood, 651 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
