Rent & eviction protection

Is 3917-3919 Noriega 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 1950
2 or more units
2 units
Property type
Multi-Family Residential

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 1950
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 property at 3917-3919 Noriega St is a two-unit, two-story multi-family residential building with a commercial ground floor, constructed in 1950 and currently owned by the Cheng Family Trust. The building's history reveals significant concerns about habitability and safety, particularly between 2015-2016, when multiple complaints were filed regarding illegal unit conversion, rodent infestations, inadequate insulation, plumbing issues, and noise disturbances from the ground-floor restaurant affecting second-floor tenants. A particularly concerning pattern emerged in early 2025, with ten consecutive reports of garbage overflow issues requiring Recology intervention, though these relate to street cleaning rather than building conditions. The property has undergone several documented modifications, including a 2007 restaurant conversion with associated plumbing and electrical upgrades (completed), installation of a cooking hood fire suppression system (2007), and various improvements dating back to the 1980s including window replacement and awning installation. A fire safety violation was issued in April 2018 regarding the storage of combustible materials, though this has since been abated. While several building and plumbing permits from 2016-2023 were either withdrawn or expired, the property shows some maintenance history such as a gas line replacement in March 2023. The most recent complaints suggest ongoing operational challenges, though these are primarily related to street-level maintenance rather than building conditions.

Risk rating

How 3917-3919 Noriega 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 632 buildings in this neighborhood, 329 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
