Rent & eviction protection

Is 227 Bay 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 1970
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.

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

227 Bay Street is a 51-unit, 3-story multi-family residential building constructed in 1970, currently managed by Bay Street LP. The property has undergone significant infrastructure upgrades in recent years, including fire safety system improvements, solar panel installations, and plumbing upgrades. Notable recent maintenance includes a concrete slab repair in unit 109 (2024), sound level compliance verification (2023), and domestic hot water boiler replacement (2023). The building's fire safety systems have received particular attention, with multiple upgrades to the fire alarm system and emergency response radio communications system (ERRCS) between 2016-2021.

However, the building has faced several concerning issues recently. In late 2023, there were complaints about ventilation problems, including kitchen exhaust issues, and unauthorized modifications in unit 318 allegedly related to drug manufacturing. A series of fire safety violations have been recorded between 2023-2024, including issues with alarm systems, sleeping area requirements, and extinguishers, though many have been corrected. The building's maintenance history shows some recurring problems, particularly with boiler permits and ventilation systems. While most building violations from 2022 and earlier have been abated, including issues with smoke alarms and carbon monoxide detectors, there remains an open violation regarding sleeping area requirements as of November 2023.

Risk rating

How 227 Bay 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
0thpercentile

Out of 362 buildings in this neighborhood, 362 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.

Neighborhood location

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