Rent & eviction protection

Is 667-669 7Th 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 1923

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 1923
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 667-669 7th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Richmond neighborhood. Built in 1923 and currently owned by the Helen Yip Ong Revocable Trust, this flats/duplex structure has undergone significant recent improvements. As of 2023-2024, major renovations have included the creation of a ground floor accessory dwelling unit (ADU) at an estimated cost of $236,854, which was permitted in June 2023 and requires the installation of ground floor fire sprinklers and a full building fire alarm system. Additional substantial work has encompassed comprehensive kitchen and bathroom remodeling in both units, voluntary lateral strengthening with plywood shear walls, and various infrastructure upgrades including the installation of a 400-amp meter main service and a Ufer ground system.

The building's recent improvements also include complete electrical rewiring and plumbing updates across various areas including kitchens, bathrooms, and living spaces, suggesting a thorough modernization of the property. Notably, there have been no reported safety violations or major maintenance issues in recent years, and the building has been actively maintained with proper permits for all significant work. The property has experienced recurring issues with driveway blocking, with seven citations issued between 2021 and 2024, indicating ongoing challenges with parking enforcement in the area. All other 311 calls related to the property have been resolved promptly, including recent reports of curb defects and street cleaning needs. The extensive recent upgrades, while improving the property's value and functionality, indicate substantial investment in modernization rather than addressing critical safety concerns.

Risk rating

How 667-669 7Th 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
97thpercentile

Out of 1723 buildings in this neighborhood, 52 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
