Rent & eviction protection

Is 506 5Th 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.

Built 1922

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 1922
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 property at 506 5th Avenue in the Inner Richmond district is a two-unit, two-story multi-family residential building constructed in 1922, currently owned by the Tang Family Revocable Trust. The building's documented history reveals several significant modifications and maintenance issues, most notably the legalization of a room and bathroom addition in the basement completed in 1990. The structure's exterior and surrounding areas have experienced recurring issues primarily related to parking and street maintenance, with the most recent concerns centering around illegal parking and sidewalk use in 2024, including a documented citation for blocking a driveway in July 2024. The property has also faced intermittent cleanliness challenges, with reports of loose garbage requiring attention in both May 2024 and December 2019, and an inspection in 2015 regarding waste receptacles being left out continuously, though no violations were confirmed upon inspection. A notable infrastructure issue occurred in 2011 when a lifted sidewalk was reported, but this was resolved by 2012 with no further action required. The building's permit and planning records indicate no current major development or zoning issues pending.

Risk rating

How 506 5Th 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.

Neighborhood percentile
64thpercentile

Out of 1723 buildings in this neighborhood, 620 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
