Rent & eviction protection

Is 3345 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 1964
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 1964
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

3345 Fillmore Street is a 12-unit, 3-story multi-family residential building located in San Francisco's Marina neighborhood, constructed in 1964. The property has undergone several significant safety improvements in recent years, including a completed soft-story seismic retrofit in 2014 (with a cost of $52,135) and a comprehensive upgrade to the fire alarm system in 2024 (costing $31,133), which included the installation of low frequency sounders in all sleeping areas to comply with AB308 requirements. The building has experienced recurring security and safety-related issues, with a notable incident in early 2021 when residents reported intercom malfunctions leading to package thefts and unauthorized entries. The property has documented multiple fire code violations between 2021-2024, though the most recent violations from 2024 were marked as "Condition Corrected" or "Abated."

The building's maintenance history shows attention to essential infrastructure, with a water heater replacement completed in 2016. Recent 311 calls (2024) indicate ongoing challenges with exterior maintenance, including reports of garbage and debris, graffiti, and sidewalk issues, though most of these cases have been resolved. The property has experienced several false fire alarm incidents between 2023-2024, including sensor malfunctions and CO detector activations, though no civilian injuries have been reported. A series of fire-related violations were documented in 2023-2024, primarily related to unpermitted operations and general safety issues, with the most recent being addressed in March 2024. The building's ownership, 3345 Fillmore Street Associates, has generally responded to regulatory requirements, as evidenced by the completion of the soft-story retrofit and recent fire system upgrades, though the property has faced periodic challenges with building systems and security maintenance.

Risk rating

How 3345 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.

Neighborhood percentile
