Rent & eviction protection

Is 1406 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.

Built 1951
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 Yu Family Trust owns this two-unit, two-story multi-family residential building, constructed in 1951 and located in San Francisco's Central Sunset neighborhood. The property's documented history shows limited structural maintenance, with only two permits on record: installation of aluminum windows in 1986 and termite work in 1984 (which expired without completion).

The building has experienced recurring vandalism issues over the past several years, with multiple incidents of offensive graffiti reported between 2018 and 2020, affecting both the building's surface and adjacent sidewalk areas. While most of these cases were resolved through official channels (including transfer to Graffiti Steamers), the frequency of these incidents is notable. In recent years (2020-2024), there have been several incidents involving garbage and debris on or near the property, with the most recent cases in August 2024 involving loose garbage and yard waste, as well as abandoned furniture. There were also two documented instances of illegal sidewalk parking near the property in early 2020, both resulting in enforcement action. While the building's age and limited permit history might raise some maintenance concerns, it's worth noting that the property has not generated any building code violations or safety-related incidents in the available data.

Risk rating

How 1406 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
91stpercentile

Out of 814 buildings in this neighborhood, 73 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Estimated permit spend (past 7 years)

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