Rent & eviction protection

Is 2700-2702 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.

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 two-unit property at 2700-2702 21st Street, located in San Francisco's Inner Mission neighborhood and owned by York St LLC, has experienced several notable events over the past seven years. Most significantly, the building underwent a substantial conversion project in 2021-2022, transforming a commercial space into a three-bedroom, two-bathroom residential unit on the first floor, during which an NFPA 13D sprinkler system was installed. The building's recent history has been marked by multiple code enforcement issues related to a vacant storefront, with the most recent active complaint filed in May 2026 concerning boarded-up windows and blight. There was also a Notice of Violation issued in late 2019 regarding compliance with vacant commercial storefront regulations, though this is not currently active.

The property has generated an unusually high volume of 311 service requests in 2026, with at least six separate reports of driveway blocking incidents all occurring in July 2026, though most could not be validated or were duplicates; one case resulted in a citation. Additionally, there was a report of garbage and debris issues in July 2026 that has since been resolved. While the building has had three Department of Building Inspection complaints filed in the past seven years, only two of these related to the vacant storefront situation are currently inactive. The building's overall condition appears to have improved with recent renovations, as demonstrated by the completion of multiple building permits totaling approximately $321,000 in construction costs, though the active blight complaint regarding boarded windows suggests ongoing maintenance challenges.

Risk rating

How 2700-2702 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
