Rent & eviction protection

Is 320-322 21St 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.

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 1912
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 320-322 21st Avenue, located in San Francisco's Central Richmond neighborhood, is a two-story multi-family residential building constructed in 1912, currently containing 3 units with a recent addition of a 4th unit on the ground floor in 2020. The building has undergone several significant improvements over recent years, with particular attention to safety features including a dedicated sprinkler monitoring system installed in 2019 (cost: $4,000) and the addition of three sprinkler heads earlier that year. Major renovation work occurred in 2018, including the installation of a new shear wall and a 2-hour rated tradesman alley. The property has seen substantial plumbing and electrical upgrades between 2017-2019, including kitchen and bathroom remodels, installation of a tankless water heater, and new electrical panel with recessed lighting.

There have been two building complaints regarding unauthorized construction in 2018 and 2019, though these are currently listed as "Not Active." The property's recent maintenance record shows regular attention to street cleanliness, with multiple 311 calls for general cleaning and debris removal between 2020-2024. The building has undergone various infrastructure upgrades including new underground systems, though some proposed improvements were cancelled or expired. Recent records from 2023-2024 show typical urban issues such as sidewalk parking violations and street cleaning needs, which have been resolved through regular municipal channels. The property underwent a pre-application meeting for constructing a new dwelling unit in the rear yard, with planning records indicating this project was subsequently closed.

Risk rating

How 320-322 21St 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
42ndpercentile

Out of 2250 buildings in this neighborhood, 1305 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
