Rent & eviction protection

Is 358-360 20Th 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 1907
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 358-360 20th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood, built in 1907 and currently owned by Wong Fan Wa. The building has undergone several significant structural improvements over the years, including seismic upgrades and foundation repairs completed in 1996 (with associated dry rot repairs), and interior alterations in 2001 that added two rooms including a study and bedroom on the ground floor. However, the property has faced notable regulatory challenges, most significantly in March 2001 when a complaint was filed regarding an unauthorized three-room apartment with full bathroom and kitchen on the ground floor, resulting in violations for improper construction without permits, inadequate fire safety features, and minimum ceiling height violations. This complaint was eventually abated by March 28, 2001.

The building's maintenance history includes several residential plumbing issues, including malfunctioning shower systems reported in late 2003, and more serious concerns documented in 1999 such as water leaks through light fixtures, ceiling issues, unsafe stairways, and access problems to utility meters. More recent activity at the property primarily involves external maintenance and neighborhood issues, with multiple 311 calls between 2017 and 2025 regarding sidewalk cleaning, garbage collection, and parking enforcement. The most recent building permits on record from 2010 were for sidewalk and street space improvements, indicating some attention to public space maintenance, though these are relatively minor compared to earlier structural work. The property's history shows a pattern of addressing significant structural issues (like the 1996 seismic upgrades) while also contending with ongoing maintenance and compliance challenges, particularly during the late 1990s and early 2000s.

Risk rating

How 358-360 20Th 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
39thpercentile

Out of 2250 buildings in this neighborhood, 1372 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

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

Building age

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