Inner Sunset, SF 94122 1767012 3 units · 2 fl · 1904

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 1345-1349 12Th 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 1904
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 1345-1349 12th Avenue in San Francisco's Inner Sunset neighborhood is a two-story, three-unit multi-family residential building constructed in 1904, currently owned by the Jean Y Chin Revocable Trust. The building has undergone significant renovations and faced multiple violations over the years, with the most substantial work occurring between 2005-2007. Major improvements included complete rewiring of all three units, installation of fire sprinklers, roof framing repairs, foundation work, garage construction, and various unit remodels. These renovations followed serious building violations from 2005 citing deteriorated stairs, inadequate plumbing and electrical systems, and roof replacement needs. The property also had historical issues with lead paint notification in 2000, though this was abated by 2015.

Prior to the renovations, the building faced significant challenges, including a 2003 withdrawn demolition permit and multiple complaints about homelessness and disrepair in the mid-2000s. There were also concerns about construction work exceeding permitted scope in 2006, particularly regarding a rear cottage and roof modifications. Since 2020, the building's issues have primarily been related to parking, with numerous complaints about driveway blocking between 2022-2024, though these are external to the building's condition. A notable recent incident involved a Christmas tree removal in January 2024, which was promptly addressed. The property's extensive renovation history suggests a substantial investment in improving building systems and infrastructure, though it should be noted that some work occurred under previously issued citations for various building deficiencies.

Risk rating

How 1345-1349 12Th 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
28thpercentile

Out of 1493 buildings in this neighborhood, 1075 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.
