Rent & eviction protection

Is 719-721 Anza St 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.

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 property at 719-723 Anza Street is a two-unit, two-story multi-family residential building located in San Francisco's Lone Mountain neighborhood, owned by Masakazu & Emiko Komatsu Fm. Built in 1941, this flats/duplex structure has undergone several significant improvements over the years, with the most recent major work occurring in 2015 when the electrical system was upgraded to a 200-amp residential service with two meters. In 2005, extensive window replacements (totaling 21 windows) and vinyl siding installations were completed, costing over $40,000 combined. Earlier renovations included a roofing project in 2003 and aluminum window replacements in 1988.

The building has experienced some maintenance and compliance issues, most notably in 2019 when a violation was recorded regarding problems with the fresh air inlet system, though this violation is currently listed as not active. The property history shows regular attention to maintenance and improvements, with all major permits recorded as completed except for a roofing permit in 2003 that expired. The surrounding area has experienced typical urban issues as documented in 311 calls, including reports of graffiti (most recently in 2022), general cleaning needs, and illegal postings, though these external matters do not directly reflect on the building's condition or management. The most recent building permit activity occurred in November 2024, involving an address correction related to the property's official records.

Risk rating

How 719-721 Anza St'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
77thpercentile

Out of 519 buildings in this neighborhood, 119 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
