Rent & eviction protection

Is 107-111 Lyon 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 1900
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 1900
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 4-story multi-family residential building at 107-111 Lyon Street, owned by the Iain Finlay Trust, was constructed in 1900 and contains 3 units. The property has undergone several significant renovations and inspections over the years, with the most recent concerning safety concerns filed in September 2023 about improper gas stove ventilation and smoke alarms. In 2009, the building underwent electrical and plumbing work to address violations from 2003-2005, including electrical rewiring of the top floor apartment and compliance with 3R reports. Multiple permits were issued in 2012 to obtain final inspections for various completed work. A deck-related complaint from 2005 about unauthorized modifications was resolved in 2012, and the building also underwent a kitchen remodel in 2008. The property has maintained regular compliance with housing requirements, though there are some recent maintenance issues noted, including a missing side sewer vent cover (opened in March 2024), and various sanitation and parking-related service calls. The building previously had security-related violations in 2003, which were promptly addressed and abated, including the installation of handrails, self-closing doors, and reinforcement of entry door glazing.

The property's historical records show attention to various maintenance and compliance issues, with most past violations being resolved through appropriate permits and work. The building underwent condo conversion preparations in the past, including plans for a rear porch and staircase replacement. Recent service calls primarily relate to exterior maintenance, parking issues, and cleaning needs, while the most pressing concerns remain focused on the recent 2023 complaint about gas appliance safety and ventilation systems. The property has a relatively controlled history of violations, with most being resolved through proper channels and permits, and no active violations currently on record.

Risk rating

How 107-111 Lyon 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
29thpercentile

Out of 581 buildings in this neighborhood, 413 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
