Rent & eviction protection

Is 2237-2241 Filbert 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-unit residential building at 2237-2241 Filbert Street in the Cow Hollow neighborhood is a three-story flats and duplex structure built in 1900, currently owned by Patrick Lew. The building has undergone several routine housing inspections by Housing Inspection Services between 2001 and 2010, all of which were properly abated, indicating normal compliance with housing standards. In 1987, there was a permit issued (now expired) for bringing the building into compliance with a requirement by Dahi, though the specific nature of this compliance is not detailed in the records.

Recent activity around the property has primarily involved street-related issues rather than building-specific concerns. There have been multiple reports of abandoned furniture on the street (three in late 2024 and one in early 2024), and several instances of Christmas tree disposal in early 2024. The property has experienced recurring driveway blocking issues, with four documented complaints between 2022 and 2023, though in each case, responding officers were unable to locate the offending vehicles. The building has also recorded one false fire alarm incident, which resulted in no civilian injuries. Overall, the building's documented history suggests regular compliance with housing standards, with most recent complaints relating to street-level issues rather than building conditions or resident concerns.

Risk rating

How 2237-2241 Filbert 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
52ndpercentile

Out of 861 buildings in this neighborhood, 413 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.

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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
