Rent & eviction protection

Is 1405 26Th 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 before 1979
Built 1958

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 1958
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 1405 26th Avenue in San Francisco's Central Sunset neighborhood is a two-story flats and duplex structure built in 1958, currently owned by the Ong Family Trust. The property has experienced several maintenance and compliance events over recent years, with the most recent being a window replacement project in July 2023 for the upper unit (#1407), which was completed at a cost of $1,157. In July 2023, there was a temporary building complaint regarding unauthorized construction and scaffolding in the back of the unit, though this complaint was promptly addressed and abated within eight days.

The building's maintenance history shows two significant sewer-related incidents in 2009 and 2012, both involving sewage backups that were resolved by PUC Sewer Operations through cleaning and flushing processes. More recently, there has been one noise-related complaint registered in June 2024 that is currently open, and a minor street cleaning issue involving an abandoned Christmas tree in February 2023 which was promptly resolved. The property's record indicates regular maintenance activity, with most issues being addressed in a timely manner, though the open noise complaint from 2024 represents the most recent resident concern on file.

Risk rating

How 1405 26Th 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
35thpercentile

Out of 814 buildings in this neighborhood, 529 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
