Rent & eviction protection

Is 101-103 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 before 1979
Built 1939
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.

15+ years since occupancy
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 property at 101-103 Stanyan Boulevard is a two-unit, two-story multi-family residential building located in the Lone Mountain neighborhood, constructed in 1939 and currently owned by the Albert L Ng Bypass Trust. The building's maintenance history includes several significant infrastructure improvements, starting from 2000 with the installation of foundation anchors and plywood work, followed by gas line extensions in 2012, and more recently, electrical system upgrades in late 2018 and early 2019 including an electrical survey and rewiring of underground connections.

The property has experienced several maintenance and safety-related issues in recent years, particularly in 2023-2024, with multiple open cases involving sidewalk defects, a collapsed sidewalk, tree root damage affecting the sidewalk, and curb defects. Two fire alarm incidents have been recorded, both of which were either false alarms or unintentional activations with no injuries reported. The building's immediate surroundings have experienced various municipal service requests, including issues with graffiti, blocked sidewalks, transportation complaints, and parking violations, though many of these cases have been resolved through official channels. The concentration of infrastructure-related permits from 2000 through 2019 suggests ongoing efforts to maintain and upgrade the building's structural and utility systems, while the recent spate of sidewalk and curb issues indicates potential public access challenges near the property.

Risk rating

How 101-103 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
70thpercentile

Out of 519 buildings in this neighborhood, 156 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
