Alamo Square, SF 94117 0822004 4 units · 3 fl · 1900

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. 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 643-647 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 1900
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 1900
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 three-story, four-unit multi-family residential building at 643-647 Fillmore Street in Alamo Square, owned by SF Mission Properties LLC, was constructed in 1900 and has undergone several significant maintenance and repair projects over the years. Most notably, in recent history, the building underwent reroofing work in 2017 at a cost of $12,000, and there have been multiple street space permits issued in 2018. The building experienced concerning issues in 2001 when multiple violations were documented, including problems with the central alarm system, water damage, damaged ceilings and walls, and smoke detector maintenance, though all these violations were abated by October 29, 2001. A routine safety inspection in 2010 revealed no active violations. More recent records show electrical, alarm system, and sprinkler complaints in December 2016, with the alarm system issue being corrected while access was not granted for other inspections. The building's maintenance history shows regular attention to building systems, though there was a period of multiple routine inspections and housing violations in the early 2000s.

The property has experienced several infrastructure and maintenance issues over its history, including water damage, crumbling plaster, and concerns about fire safety systems. Most recently, in 2023, there was a report of a collapsed sidewalk adjacent to the property that was resolved, and there have been multiple reports between 2020-2021 regarding garbage receptacle management and general cleaning needs. The building underwent roof replacement work in 2017, representing some investment in maintenance, though the age of the building suggests ongoing maintenance requirements. While there have been periodic violations and maintenance issues, particularly evident in the 2001 and 2005 cycles of complaints and violations, recent records indicate fewer systematic problems, with most recent complaints being promptly addressed. The property has also generated multiple 311 calls regarding street cleaning and refuse management between 2020 and 2023, suggesting ongoing attention to exterior maintenance and neighborhood relations.

Risk rating

How 643-647 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.

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.

Number of units

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
