Rent & eviction protection

Is 160 Blake 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 1973
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1973
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 2-story, 4-unit multi-family residential building at 160 Blake Street in the Lone Mountain neighborhood, currently owned by the Margaret Lau Trust, was constructed in 1973 and has experienced several significant events throughout its history. The building underwent fire damage repairs in 2007 affecting apartments #2 and #4, requiring sheetrock and flooring work in the kitchen and one bedroom, along with associated plumbing and electrical work. Window upgrades have been documented through two permits: in 2019, four aluminum slider windows were replaced at the front of the building, and in 2011, eight vinyl windows were replaced at the back of the building with energy-efficient specifications. A notable resident complaint was filed in 2010 regarding damp carpets and mold on windows, which was resolved within two weeks.

The building's maintenance history shows attention to both interior improvements and safety systems, though there was one significant incident on record related to a carbon monoxide detector activation (with no detected CO) and two routine housing inspections in 1999 and 2004. Recent activity at the property has primarily consisted of external issues, including multiple parking enforcement calls in 2024 for driveway blocking, a 2023 report of an overflowing city garbage can, and a 2019 street flooding issue related to a water service line problem. While the building's history includes some concerning events (e.g., fire damage, water issues, and a mold complaint), it also demonstrates regular maintenance through window replacements and compliance with safety systems, with no recent building complaints on record through 2023.

Risk rating

How 160 Blake 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
48thpercentile

Out of 519 buildings in this neighborhood, 270 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Owner's portfolio size

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