Rent & eviction protection

Is 3120-3122 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 1900
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 3120-3122 21st Street property, located in San Francisco's Inner Mission neighborhood, is a two-unit, two-story building constructed in 1900 and currently owned by Kevin Mark Dolan. The building's recent history has been notably impacted by a significant incident in April 2022, when a car crashed into the garage structure, causing substantial damage including to the garage opening post and rear garden door. This event triggered emergency responses, with gas and electric services temporarily shut off, and subsequently led to two building permits in 2022-2023 for emergency repairs valued at over $100,000, including restoration of garage walls, foundations, windows, and doors.

Over the past seven years, the property has generated a substantial number of 311 service requests (1170), indicating a high level of maintenance or accessibility issues, though many of these may be routine urban living concerns. There were two building inspection complaints in 2022, one being construction noise before 8 AM and the other relating to the aforementioned automobile accident. While these complaints have been closed, and a single Notice of Violation was recorded in relation to the garage damage, it's worth noting that the building's permitted repair work was completed as of early 2023. The building's service request patterns in recent years (2023-2025) show recurring issues with the surrounding area, particularly regarding garbage and debris, though these are external to the building itself. The relatively high number of service requests and the nature of some reported issues suggest ongoing challenges with the property or its immediate environment, though the most significant structural issues from the 2022 incident have been addressed through proper permit processes and repairs.

Risk rating

How 3120-3122 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.

Neighborhood percentile
52th percentile

Out of 2380 buildings in this neighborhood, 1142 are predicted to be safer.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

Building age
