Rent & eviction protection

Is 3839-3841 26Th 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.

Built before 1979
Built 1909

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 1909
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 3839-3841 26th Street in Noe Valley is a two-unit, two-story multi-family residential building constructed in 1909, currently owned by the McKown Family Trust. The building has undergone several significant maintenance and improvement projects over the past two decades, with the most recent being a completed re-roofing project in 2015 costing $17,125. More substantial structural work was performed in 2005 when steel girders and supports were added to the garage at a cost of $20,000. Earlier modifications include the completion of various deck-related improvements in 2003, including work on the rear deck, and a horizontal addition project initiated in 1999 (though this permit ultimately expired).

The property has experienced minimal neighborhood-related issues in recent years. The most recent incident was a parking-related service request in May 2024 that remains open. Prior to that, there was a resolved parking enforcement case in April 2023 involving a vehicle parked on the sidewalk. An unrelated service request regarding waste receptacles left out was submitted in 2015, but this case was deemed invalid by the Department. The building's permit history suggests regular maintenance and structural improvements, with no recorded building code violations or safety concerns in the available data.

Risk rating

How 3839-3841 26Th 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
79thpercentile

Out of 1879 buildings in this neighborhood, 395 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
