Rent & eviction protection

Is 1390 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.

Built before 1979
Built 1954
2 or more units

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 1954
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 8-unit, 2-story apartment building at 1390 12th Avenue in the Inner Sunset, owned by Ng Trust, has undergone several significant maintenance and safety upgrades since its construction in 1954. The building completed a mandatory soft-story retrofit in 2017 (Tier 3) with improvements including plywood shear walls and holdowns. Recent major repairs include substantial work in 2022 involving replacement of damaged boards on front stairs and window siding, along with addressing multiple water-related issues including leaks through windows and ceilings, and termite damage. The building has a documented history of maintenance challenges, particularly relating to water damage, with multiple complaints between 2013-2022 regarding leaks, ceiling issues, and structural concerns such as floor board stability. Historical violations from 2001 indicate previous safety concerns including stairs requiring repairs, fire extinguisher maintenance needs, and lead paint hazards, though these were resolved within a few months. More recent active violations from 2017 remain regarding fire safety requirements for carbon monoxide/smoke alarms and fire extinguisher maintenance.

The property's maintenance history shows regular attention to basic infrastructure, including window replacements (2013), reroofing projects (2012 and 1994), and various repairs to address decay and weather-related damage. The building has experienced recurring issues with garbage and debris management in the surrounding area, as evidenced by multiple 311 calls for street cleaning and abandoned items just in 2024. While many past violations and complaints have been resolved, the presence of active violations from 2017 regarding fire safety compliance suggests some ongoing maintenance challenges. A recent series of 311 calls regarding temporary encampments and illegal parking near the property was documented in late 2023 and early 2024, though these incidents appear to be street-related rather than building-specific issues.

Risk rating

How 1390 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
9thpercentile

Out of 1493 buildings in this neighborhood, 1359 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
