Rent & eviction protection

Is 2151-2153 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 1909

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.

Built 1909
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 multi-family residential building at 2151-2153 Filbert Street in Cow Hollow, owned by 2000 Kozma/malone Family Tr, was constructed in 1909 and contains two legal dwelling units. The building has undergone several significant renovations, most notably a substantial 2018 renovation to unit #2153 that included kitchen and bathroom remodeling, wall modifications, footing work, and the addition of new fixtures, which was properly documented with building, plumbing, and electrical permits totaling approximately $55,000. Other documented improvements include a solar PV installation in 2008, various electrical upgrades in 2003, and sewer work in 2011. However, as of August 2024, the property is currently facing serious regulatory challenges following a complaint that revealed potentially unauthorized modifications, with inspectors noting evidence of at least three units having been constructed without proper permits or inspections between 1999-2008. This situation has resulted in multiple life safety violations being cited, including issues with egress, heating, fire safety, and proper habitation standards, leading to its designation as a nuisance property. The building's maintenance history includes roof replacements in 1993 and 2001, and it has recently experienced various street-related issues such as garbage debris removal, parking violations, and hazardous materials concerns, though these are primarily external to the building itself. While the recent renovation work demonstrates some level of property upkeep, the ongoing legal and safety compliance issues represent significant concerns that require attention.

Risk rating

How 2151-2153 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
75thpercentile

Out of 861 buildings in this neighborhood, 215 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
