Is 471 6Th Ave 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.
Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.
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.
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.

Unlock complete reportThe property at 471 6th Avenue in the Inner Richmond is a two-story, 4-unit multi-family residential building constructed in 1974 and owned by Chen Chan Chuan. The building has undergone significant renovations over the past decade, with the most recent major work occurring in 2019 when twelve front windows were replaced with Milgard aluminum series windows to comply with building codes. Prior to this, in 2018-2019, substantial remodeling occurred in multiple units, including renovations to kitchens, bathrooms, and bedrooms across units 1, 3, and 4, with an initial complaint in 2018 regarding potentially structural changes involving kitchen wall removal. The building experienced several notable issues between 2015-2019, including multiple fire safety violations in 2019 related to blocked exits, fire extinguishers, combustible materials, and sprinkler systems, though these were subsequently corrected and abated. There have been past concerns regarding unauthorized work, as evidenced by a 2019 complaint about unpermitted window replacements, though this was later addressed through proper permitting. The building underwent routine housing inspections in 2002, 2010, and 2015, and has had several maintenance updates including a new roof in 1988 and 2004, and the installation of AC stair lifts in 2011. Recent infrastructure issues include documented flooding and sewage backup incidents in 2024, suggesting potential ongoing plumbing system challenges. The property has had periodic issues with parking enforcement, mechanical equipment noise, and various environmental maintenance matters as recorded in 311 calls.

How 471 6Th Ave'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.
Out of 1723 buildings in this neighborhood, 1585 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
