Rent & eviction protection

Is 115-117 Sanchez 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 1906
2 or more units
3 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 1906
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, three-story multi-family residential building at 115-117 Sanchez Street, located in the Duboce Triangle neighborhood, was constructed in 1906 and is currently owned by Tom Jun Kwock & Wai Kuen. The property has undergone several renovation projects over the years, with the most recent significant work occurring in 2015, including bathroom tile repairs and kitchen cabinet replacements in multiple units. However, more concerning issues have emerged in recent years regarding unauthorized construction activities. There are active unresolved complaints from 2018-2020 about unauthorized room additions and a suspected roof deck installation, with allegations of potential fire hazards due to unpermitted work. The building has a history of maintenance issues, including multiple violations in 2011-2013 related to water damage, mold, and lead paint hazards that were eventually resolved. Earlier violations from 2002 related to fire safety concerns about security bars and fire escape ladders were also resolved, along with various building permits for routine maintenance and repairs.

The property has experienced several infrastructure and safety concerns over the past two decades, including a 2011 water leak incident in an extended kitchen area, various bathroom maintenance issues, and unauthorized construction work. Historical records show proper attention to resolving most cited violations, though the recent complaints regarding unpermitted construction work remain a significant concern. The building's exterior has faced occasional issues such as graffiti, with the most recent case being recorded in December 2023. The property has undergone periodic interior improvements, with multiple permits issued between 2013-2015 for various repair and renovation projects across different units, suggesting ongoing maintenance efforts by the property owners despite the recent concerns about unauthorized construction activities.

Risk rating

How 115-117 Sanchez 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
31stpercentile

Out of 287 buildings in this neighborhood, 198 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
