Rent & eviction protection

Is 2767 21St 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 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 2767 21st Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1909, this flat and store structure is currently owned by the Jack & Maria Osorno Rvc Trust. The building has undergone several maintenance and infrastructure updates over the years, most notably a reroofing project completed in 2012 at a cost of $9,903 and a water service replacement between the garage and meter in 2021, though this permit was subsequently cancelled while the associated plumbing work was completed under a different permit. A furnace installation project planned in 2011 was cancelled prior to completion.

The property has experienced various maintenance and public safety issues in its vicinity over the past few years. Most recently, in 2025 and 2024, there have been two reports of damaged trees, including a fallen tree and a hanging limb. Other notable incidents include a noise complaint related to entertainment reported in April 2021, which was resolved when the business owner was educated about noise regulations and agreed to comply with sound limits. The area has also experienced recurring parking enforcement issues, with several reports of blocked driveways and sidewalk parking between 2021 and 2024. More recent concerns include graffiti (July 2023), an encampment (December 2023), and general street cleaning needs (September 2022). A February 2024 service request to the Department of Building Inspection was transferred to the Customer Experience Services for further processing. While these issues primarily relate to the surrounding area rather than the building itself, they may impact resident quality of life.

Risk rating

How 2767 21St 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
67thpercentile

Out of 2380 buildings in this neighborhood, 785 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
