Rent & eviction protection

Is 617-619 Natoma 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 1911
2 or more units
4 units
Property type
Multi-Family Residential
Zoning

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 1911
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-unit, 2-story apartment building at 617-619 Natoma Street in San Francisco's South of Market neighborhood, owned by Wesley & Charlene Chan, was built in 1911 and has undergone several significant renovations and faced various maintenance challenges over the years. Most recently, in 2024, the building has experienced multiple issues including broken windows and paint drippage (June 2024), light flickering and fan problems (October 2024), and excessive noise complaints (May 2024). A substantial sewer-related incident occurred in August 2018, involving water intrusion in the basement that was linked to the building's sewer lateral connection, though this was subsequently resolved through complete replacement of the sewer line and house trap in September 2018. The building has undergone several renovation projects, including comprehensive updates to multiple units' kitchens and bathrooms in 2001 ($25,000) and electrical improvements in 2005.

The property has a documented history of safety and maintenance issues, particularly in the 2004-2005 period when multiple violations were filed including problems with fire safety elements (e.g., missing fire extinguishers, electrical outlets, and egress obstructions), though these were all abated by June 2005. More recent fire safety concerns include violations for sleeping area requirements (October 2023), alarm system maintenance (2021), and sprinkler systems (2017-2018). The building has experienced recurring issues with public space maintenance, as evidenced by multiple 311 calls in late 2024 regarding graffiti and debris. While many historical violations and complaints have been resolved, the property continues to show patterns of periodic maintenance issues and violations related to both building systems and safety infrastructure.

Risk rating

How 617-619 Natoma 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
33rdpercentile

Out of 430 buildings in this neighborhood, 288 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
