643 7Th Ave

Inner Richmond, SF 94118 1637008 2 units · 2 fl · 1911

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 643 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 1911

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.

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 two-unit residential building at 643 7th Avenue in San Francisco's Inner Richmond District is a two-story flats and duplex structure built in 1911, currently owned by Eleanor Y. Leung. The building underwent a permitted renovation in 1998 to add a bathroom and bedroom to the lower level, which was completed successfully.

The property has experienced several maintenance issues over the years, particularly with the public sidewalk area, which has been documented in multiple complaints between 2014-2016. These included multiple reports of lifted sidewalk defects in February 2014, with at least four separate incidents being reported and documented as damaged, though most were resolved satisfactorily. There were also two instances of sidewalk parking violations reported in 2022, and two more recent complaints about sidewalk parking in early 2025, though enforcement officers were unable to locate the vehicles in each case. Additional minor incidents included a 2017 report of graffiti, which was determined to be a non-valid street lighting issue, and a 2021 case involving illegal multiple postings that was resolved by the Department of Public Works. While the building itself appears to be structurally sound with no recent major complaints or violations on record, the surrounding sidewalk area has experienced recurring maintenance issues that were primarily addressed through official channels.

Risk rating

How 643 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
15thpercentile

Out of 1723 buildings in this neighborhood, 1465 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
