Rent & eviction protection

Is 1270-1274 4Th 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 1909
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 three-unit, three-story multi-family residential building at 1270-1274 4th Avenue, owned by Henry & Julia Yim, was constructed in 1909 in San Francisco's Inner Sunset neighborhood. The property's significant issues emerged in early 2003 when violations were filed regarding an unauthorized retaining wall construction, which was reportedly built approximately 2 feet higher than approved plans, leading to a stop work order on February 19, 2003. Subsequent complaints followed regarding expired building permits and unauthorized work in the rear yard area, with multiple permit revisions and renewals occurring throughout 2003. The situation escalated with several inspections and violations throughout 2003-2004, though these were ultimately abated by December 2003.

In the years following these incidents, the property has undergone regular routine inspections by Housing Inspection Services in 1997, 1999, 2005, 2010, and most recently in 2017, all of which were noted as not active. A 2018 case regarding graffiti on a sign was resolved by the Department of Public Transportation. Planning records indicate the rear yard area has been associated with parking use, with documentation showing concerns about the creation of a parking area extending to the property line, though this issue was marked as resolved. The building's permit history shows several attempts to address and document various construction and modification projects, with the most significant activities occurring between January and September 2003, including work on the rear yard retaining wall, garage modifications, and related permit renewals.

Risk rating

How 1270-1274 4Th 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
36thpercentile

Out of 1493 buildings in this neighborhood, 956 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
