Rent & eviction protection

Is 89-91 Stanyan Blvd 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 1939

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 1939
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 89-91 Stanyan Blvd, owned by Kwong Edward & Ma Thuy Phun, is a duplex structure built in 1939 in the Lone Mountain neighborhood. The property has undergone significant renovations from 2016 to 2019, with the most substantial work occurring in 2017 when two bathrooms and a kitchen were remodeled, along with electrical rewiring, plumbing updates, and insulation improvements totaling approximately $130,000 in combined costs. These renovations included the addition of new fixtures, bathroom facilities, and updated electrical systems with a 200-amp service upgrade. In 2018, further improvements were made including the addition of two bathrooms, laundry facilities, tankless water heaters, and furnace relocation, though some associated permits expired without finalization until their renewal and completion in 2019.

The building has had minimal complaints on record, with only one building-related complaint in 2018 regarding construction site cleanliness, though this issue was not marked as resolved in the records. A routine housing inspection from 2003 was completed without any noted concerns. The property has maintained regular updates to its infrastructure, including plumbing systems with multiple component replacements, such as sewage lines and various bathroom fixtures. The most recent building permit activity was recorded in 2019 for street space use, and there have been no significant safety-related incidents or violations documented against the property in recent years. The extensive renovation work suggests regular maintenance and upgrading of building systems, though prospective tenants should note that some permits required renewal or reactivation to reach completion status.

Risk rating

How 89-91 Stanyan Blvd'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
72ndpercentile

Out of 519 buildings in this neighborhood, 145 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
