Rent & eviction protection

Is 670-672 47Th 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 before 1979
Built 1960
2 or more units
2 units
Property type
Multi-Family Residential

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 1960
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 670-672 47th Avenue is a two-story, two-unit multi-family residential building constructed in 1960 and currently owned by the Wang Living Trust. The building has undergone several significant maintenance and repair projects over the past decades, with the most notable recent history centering around water damage issues. In 2019, multiple violations were recorded related to water damage, including problems with interior surfaces, mold/mildew, and fan repairs, which were all addressed by September 2021 through a comprehensive kitchen and bathroom remodeling project costing $30,000. The building has received regular maintenance attention, including reroofing projects in 2005 and 2018 (costing $7,500 and $8,500 respectively), a window replacement and exterior improvements in 2009, and structural repairs like back staircase work in 2001 and dry rot remediation in 1990. More recent improvements include significant electrical upgrades in 2021, with the installation of a new 200A electrical service and laundry facilities, as well as plumbing modifications to accommodate washer machine installation.

The property's recent history shows proper remediation of major issues, with the 2019 water damage incidents being fully resolved by late 2021, including the installation of new utility infrastructure. Safety concerns were also addressed promptly, such as a blocked exit issue in 2021 that was corrected the same day. The building's maintenance record shows regular upkeep through various permits, though some historical issues like plumbing system repairs in 1989 and window upgrades in 2009 indicate ongoing attention to building preservation. Recent community reports through 311 calls have primarily focused on external issues like street cleaning, parking enforcement, and graffiti, rather than building-specific problems, suggesting the property is currently maintaining a stable condition. While there have been multiple instances of vehicles blocking driveways near the property (most recently in January 2024), these are external neighborhood issues rather than building-specific concerns.

Risk rating

How 670-672 47Th 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
62ndpercentile

Out of 1040 buildings in this neighborhood, 395 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
