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 2003
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 three-story mixed-use building at 4735 Mission Street, constructed in 2003, comprises two residential units above a ground-floor commercial space, with ownership registered under Chen Yun & Jian Yan. The building's construction was completed following a significant February 2001 permit for adding two stories to the existing single-story commercial structure, valued at $450,000, which was supported by electrical upgrades including a 3-phase 400-amp underground service installation with four meters in January 2003. Since its completion, the property has undergone several maintenance and modification works, including a $22,000 reroofing project in December 2018.

Recent concerns regarding resident safety have emerged, particularly in mid-2024, with an open investigation into blocked common area exits that resulted in fire violations for storage in pathways and blocked roof exit access, though these violations were subsequently abated. The building has experienced recurring maintenance issues, including a sewage backup in October 2023 and multiple reports of general cleaning needs on the surrounding property. Vandalism has been a concern, with multiple graffiti incidents reported on or near the building in 2024. The property's history includes several early 1990s commercial modifications, including kitchen hood installations and partition wall alterations, before its conversion to its current configuration. The building has undergone fire safety inspections and modifications over the years, with records indicating the installation of a fire system in the kitchen hood in 1994 and various fire safety improvements throughout its history.

Risk rating

How 4735 Mission 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
8thpercentile

Out of 337 buildings in this neighborhood, 310 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
