Rent & eviction protection

Is 3620 Fillmore 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.

Built before 1979
Built 1966
2 or more units
12 units
Property type
Multi-Family Residential
Zoning

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1966
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 12-unit, 3-story apartment building at 3620 Fillmore Street in the Marina district, constructed in 1966 and currently owned by 3620 Fillmore St LLC, has undergone several significant safety and maintenance improvements over the past decade. Most recently, in 2024, the building completed a fire alarm system upgrade to install 27 low-frequency sounders in sleeping areas, along with associated electrical work. The building previously addressed critical safety requirements through a mandatory seismic retrofit completed in 2015 (with a cost of $33,000), and window replacements in 2013. The property has maintained its soft-story compliance status as "Work Complete, CFC Issued".

The building has experienced recurring fire safety system issues, with multiple fire complaints documented between 2016 and 2023 regarding alarm systems, extinguishers, and sprinkler systems, though all have been marked as "Condition Corrected" or "Violation Issued". Two violations related to boiler permits in 2018 and 2020 were resolved by June 2020. Historical records show previous structural work including foundation underpinning in 1995, reroofing in 1993, and parking slab replacement in 1989. Recent external maintenance has been documented through multiple 311 calls in 2024 regarding street cleanliness issues near the property, though these are not directly related to the building's condition or safety systems. Additionally, there is one open case from May 2024 regarding offensive graffiti on the sidewalk and a tree maintenance issue from January 2024.

Risk rating

How 3620 Fillmore 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
