Inner Richmond, SF 94118 1437045 24 units · 3 fl · 1961

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 310 6Th 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 1961
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

310 6th Avenue is a three-story, 24-unit multi-family residential building constructed in 1961, currently owned by 310 6th 15 LLC. The property has undergone significant improvements in recent years, with Unit #24 receiving comprehensive kitchen and bathroom upgrades in 2022 (following a cancelled permit in 2022), and previous units (22, 21, 15, 12, 10, 23, and 19) also undergoing similar renovations between 2017 and 2024. The building has maintained attention to safety systems, with a mandatory fire alarm upgrade completed in 2019 ($78,000) to add low-frequency sounders in sleeping areas to meet code requirements. Several windows have been replaced or upgraded throughout the building, including recent work on the building's front facade with stucco replacement in May 2024.

The property has experienced some maintenance and safety issues over the years, with a notable cluster of violations in 2006 that were all abated by November 13, 2006, including concerns about fire safety (gas shutoff tools, fire extinguishers), electrical issues (light fixtures), and safety access (tradesperson walkway obstructions). More recent issues have included a 2017 complaint about window leaks and door sealing, and fire safety violations in 2022 related to alarm systems, though these were corrected. A plumbing issue was addressed in 2018 involving the house trap, and multiple 311 calls regarding garbage and debris have been recorded in late 2024, suggesting ongoing challenges with exterior maintenance. The building's systems have been regularly updated, including a new domestic hot water system installation in 2014, though an attempt to add seven ADU units at the ground floor in 2022 was filed but not completed.

Risk rating

How 310 6Th 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
1stpercentile

Out of 1723 buildings in this neighborhood, 1706 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Property class (A15)

The assessor's property-class code, which correlates with building type and the violation rates the model expects.
