Rent & eviction protection

Is 1109-1113 Montgomery 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 1912

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 1912
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-unit multi-family residential building at 1109-1113 Montgomery Street in Telegraph Hill, owned by Poy Lun Yee Tom Survivors T, is a three-story 1912 structure that has undergone several significant renovations and repairs over the past decades. The most substantial recent work occurred in 2012, including a comprehensive $55,000 remodel of unit #1109 that involved relocating the kitchen, converting an existing kitchen into a study, remodeling bathrooms, and adding new features including laundry facilities. This project was accompanied by necessary electrical upgrades from 100amp to 300amp service and plumbing modifications. More recent maintenance includes the replacement of underground sewage pipes in May 2021, indicating attention to critical infrastructure. The building experienced multiple violations and complaints in late 2009 through early 2010 regarding inadequate heating, window issues, and electrical problems, though all these violations were abated by March 2010. A subsequent complaint in 2020 raised concerns about COVID-19 safety practices during construction work, highlighting the property's historical relationship with maintenance and safety compliance.

The property has maintained regular upkeep, as evidenced by various permits and repairs, including dry rot repairs in 2012 and heater replacement in 2010. Several routine housing inspections have been conducted over the years, with the most recent significant issues being addressed through proper channels. The building now appears to have no active violations or complaints on record since 2020. Recent 311 calls (from late 2024) primarily concern street-related issues such as parking violations and sidewalk access, which are managed by city services and not directly related to the building's condition or management. While historical maintenance issues are documented, recent permits and completed work suggest a pattern of addressing necessary repairs and improvements, though the age of the building naturally presents ongoing maintenance considerations.

Risk rating

How 1109-1113 Montgomery 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
22ndpercentile
