Rent & eviction protection

Is 30-32 Coso 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 1900

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 1900
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

This two-unit residential building, located at 30-32 Coso Ave in Bernal Heights, is a 2-story structure built in 1900 and owned by Liu Fangge & Xu Wenjing. The property has undergone several significant improvements over the past few decades, with the most notable recent renovations occurring in 2016, when a comprehensive kitchen remodel was completed along with the installation of new aluminum windows to replace vinyl ones. This renovation project, valued at $24,800, included plumbing updates for a new kitchen sink and dishwasher, as well as electrical work for additional circuits and lighting. The building's maintenance history shows attention to infrastructure, with a sewer repair completed in 2012, replacement of water heaters in 2015, and various other improvements including backyard stair repair in 2008.

The property experienced a water-related issue in 1997 that was formally documented, involving rainwater crossing property lines, though this complaint was abated in 2001. The building's age shows through its historical improvements, including reroofing in 1997, installation of aluminum windows in 1986, and application of Alcoa siding in 1985. More recent municipal interactions near the property have primarily involved street and sidewalk issues, with several 311 calls related to urban maintenance matters such as pavement defects and waste cleanup. While there have been various service requests logged through 311, these mostly pertain to neighborhood issues rather than building-specific problems, and most have been resolved through normal municipal channels. The property's official planning records indicate compliance with window replacement requirements, with all related enforcement cases marked as abated.

Risk rating

How 30-32 Coso 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
84thpercentile

Out of 1276 buildings in this neighborhood, 204 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Building age

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