Rent & eviction protection

Is 2485-2489 Folsom 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.

Built 1912
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 6-unit multi-family residential building at 2485-2489 Folsom Street in the Inner Mission, built in 1912 and currently owned by 2375 Zanker LLC, has undergone several significant structural and safety improvements in recent years. Most notably, the building completed a mandatory seismic retrofit in 2022 at a cost of $65,000, achieving compliance with San Francisco Building Code requirements. The property has experienced ongoing plumbing issues, with a significant sewage pipe problem in 2021 that required concrete work and repair, and there are current plans for electrical system upgrades including the removal of old Federal Pacific panels in 2025. The building's History of Building Violations reveals a pattern of maintenance issues that required attention, including water damage repairs, drainage pipe work, and sanitation concerns, particularly in 2021 when multiple violations were addressed between June and October.

The property has a documented history of various maintenance and safety concerns dating back to the early 2000s, including interior surface issues, mold, security concerns, and problems with building systems. Recent inspections have shown some persistent issues, with an active health and safety inspection case filed in March 2023 still showing as pending. While the building has completed various structural improvements, including reroofing in 2012 and basement renovations, there have been significant service interruptions such as the 2021 sewage leak. Recent focus has been on improving building systems and infrastructure, as evidenced by the completed seismic retrofit and upcoming electrical panel upgrades, though these improvements have been accompanied by various plumbing and electrical work permits over the years. The building's location in a historically earthquake-prone area has necessitated particular attention to seismic safety requirements, which have now been addressed through the completed soft-story retrofit program.

Risk rating

How 2485-2489 Folsom 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
12thpercentile

Out of 2380 buildings in this neighborhood, 2094 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
