Rent & eviction protection

Is 3139-3141 Irving St 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.

15+ years since occupancy
Built 1948
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 two-unit residential building at 3139-3141 Irving Street in the Central Sunset neighborhood is a two-story flats/duplex structure built in 1948, currently owned by the Guan Family Trust. The building's maintenance history reveals some significant events, particularly in 2009 when multiple repairs were made to address fungus damage and dry rot, including the replacement of a joist over the garage door, sill at a rear window, and portions of the back stair, with an associated cost of $800. That same year, a substantial electrical upgrade was completed, installing a 200-amp setup with two panels, two meters, ten circuits, and two lights in the basement. The only documented building complaint on record was from 2002 regarding heating issues in the kitchen, living room, and bathroom, though this was resolved within a week.

The property has experienced various maintenance and enforcement issues in recent years, with a notable cluster of parking-related incidents recorded between 2021 and 2025, particularly in late 2022 when there were multiple reports of driveway blocking by different vehicles, including silver BMWs. All these parking enforcement calls resulted in either citations or inability to locate the offending vehicles. Two 311 calls in June 2022 addressed the problem of waste receptacles (toters) being left out continuously, which led to outreach and enforcement action. The most recent incident occurred in January 2025 regarding sidewalk parking, though inspectors were unable to validate the reported issue. The building appears to be regularly monitored for maintenance issues, with the most recent significant repairs dating back to 2009, suggesting either good building preservation or potential deferred maintenance, though no recent complaints or violations have been recorded.

Risk rating

How 3139-3141 Irving St'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
81stpercentile
