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 1988
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

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 nine-story multi-family residential building at 737-747 Folsom St, managed by Todco/ybc 3, Ca N.p. P.b. C, was constructed in 1988 and contains 189 units. The building has undergone several significant safety and maintenance upgrades in recent years, most notably a comprehensive fire alarm system retrofit completed in 2023 (cost: $1,148,000) to comply with SF ordinances and NFPA standards, followed by revisions to implement a voice evacuation system in late 2023. Multiple fire code violations were issued between 2019 and 2024, with recent violations in 2024 regarding sleeping area requirements and various safety equipment concerns that remain open. The building's maintenance history includes a 2013 reroofing project, replacement of hot water and heating boilers in 2009, and various electrical and plumbing upgrades.

The property has experienced several resident complaints over the years, with the most recent being a possible water leak and mold issue reported in 2022. Housing Inspection Services records from 2010 show multiple violations related to sanitation and fire safety, though these were abated by December 2010. Other complaints have included security concerns (2016), cooking odor issues (2014), and a routine safety inspection in 2011. Recent 311 calls from early 2025 indicate ongoing urban challenges in the surrounding area, including reports of human waste, debris, and parking violations. The building's fire incident history shows primarily false alarms and system malfunctions, with one recorded cooking container fire and a gas leak incident, none resulting in civilian injuries.

Risk rating

How 737-747 Folsom 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
13thpercentile

Out of 23 buildings in this neighborhood, 20 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
