Rent & eviction protection

Is 649-653 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 1898

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 1898
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 3-unit residential building at 649-653 Fillmore Street in Alamo Square, owned by Eileen Trom Cassidy, is a 3-story flats and duplex structure built in 1898. The property has undergone several significant improvements in recent years, most notably a comprehensive renovation of the first-floor unit in 2021 that included new electrical wiring and panel installation, kitchen and bathroom updates, and plumbing improvements. This renovation was initially done without proper permits, leading to a violation that was subsequently resolved. The building's electrical system received substantial upgrades in 2021, including a new 200-amp service installation and rewiring throughout the unit.

The property has experienced some concerning maintenance issues recently, particularly with the exterior spiral staircase, which has been the subject of multiple complaints in 2023 regarding stability concerns and its impact on the adjacent building. Historical records show various maintenance work, including a 2006 reroofing project and several permits from 1988 for various repairs including work on the rear stairs and ground-level plaster walls. The building has faced several regulatory inspections and violations over the years, particularly in the mid-2000s, focusing on fire safety and plumbing systems, though these were all resolved. Recent 311 calls primarily relate to external issues such as sidewalk cleaning and graffiti, with no significant building safety concerns noted in recent inspections. The property appears to be maintaining compliance with current building codes, though the recent staircase stability concerns may warrant attention.

Risk rating

How 649-653 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

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
53rdpercentile

Out of 305 buildings in this neighborhood, 143 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
