Rent & eviction protection

Is 133 Cook 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.

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.

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 4-unit, 2-story multi-family residential building at 133 Cook Street in the Lone Mountain neighborhood, currently owned by Y & K Partners LLC, has undergone several notable developments since its construction in 1969. Most recently, the property has seen the installation of solar panels, with two completed permits in 2024 for Unit 4, each featuring 10 PV modules of 395 watts. The building's maintenance history includes a significant cluster of violations recorded in late 2007 through early 2009, primarily related to safety and maintenance issues such as fire safety equipment, lobby repairs, and heating system concerns. All these violations were officially abated by January 20, 2009. The building also experienced one documented gas-related incident (type 412) with no civilian injuries, though the exact date and details are not specified in the records.

Recent external activity around the building has primarily involved municipal services, including three parking enforcement calls for blocked driveways between 2019 and 2022, and various maintenance issues such as graffiti removal (January 2023) and general street cleaning (January 2023). While the building has a history of maintenance issues dating back to at least 1999, records indicate that these have generally been addressed in a timely manner, with no active violations or complaints in recent years. The most recent routine inspection noted in the records was conducted in 2009, and there have been no documented heating system issues since the 2009 complaint about Unit 3's heating unit.

Risk rating

How 133 Cook 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
47thpercentile

Out of 519 buildings in this neighborhood, 275 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.

Estimated permit spend (past 7 years)

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.
