Rent & eviction protection

Is 1330 31St 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 1947
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 1947
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 Robert J Hoffman 2017 Trust owns this two-story, three-unit multi-family residential building located at 1330 31st Avenue in San Francisco's Central Sunset neighborhood. Built in 1947, the property has undergone several significant improvements over the decades, including the installation of an interior staircase and kitchen in 1990, the addition of a second-floor bathroom in 1992, and resolution of a stairway violation involving plywood removal in 1993. In recent years, the building has experienced recurring issues with abandoned vehicles and parking violations in the vicinity, particularly in 2023-2024, though these are external to the building itself. There were notable hot water system problems in February 2007, with multiple complaints filed regarding insufficient hot water for the units, though these were resolved within a week. The property has also seen some sidewalk-related issues, with three reports of collapsed sidewalk conditions in May 2023, though inspections found no defects at the time. A fire alarm system complaint in March 2019 was determined to be beyond jurisdiction.

The building's permit history shows relatively modest maintenance and improvement work, with the most recent permits dating back to 2006 for sidewalk repairs, suggesting basic infrastructure maintenance requirements have been addressed when necessary. The property's historical permits indicate it has been appropriately modified over time to meet evolving residential needs, though the 2007 hot water issues suggest there may have been some limitations in the building's systems at that time. The recent 2023 sidewalk defect reports, despite having no issues found upon inspection, indicate this area may require ongoing monitoring.

Risk rating

How 1330 31St 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
34thpercentile

Out of 814 buildings in this neighborhood, 537 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
