Rent & eviction protection

Is 642-646 Ashbury 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.

Built 1906

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.

Built 1906
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 three-unit, three-story multi-family residential building at 642-646 Ashbury St in Haight Ashbury, constructed in 1906, has undergone several significant maintenance activities in recent years. Most notably, in June 2023, the property received a substantial reroofing project costing $22,850, following a previous expired roofing permit from 1990. In October 2021, plumbing improvements were completed to install laundry facilities. The building experienced a cluster of maintenance issues in late 2023, with multiple violations recorded in October 2023 relating to interior surfaces, plumbing, electrical systems, and safety equipment. These violations included problems with walls, ceilings, floors, sinks, toilets, and the requirement for carbon monoxide and smoke alarm affidavits. All of these violations were officially abated by March 2024.

In addition to the violation cases, there were also building complaints from late 2023 regarding insufficient heat and various maintenance items. The property has maintained its regular inspection schedule, with routine inspections noted in 1997, 2000, and 2006. A significant amount of street-level issues have been documented through 311 calls in 2023-2024, including reports of graffiti, garbage, sidewalk parking violations, and maintenance concerns, though these are more reflective of the street environment than the building's condition. The building's maintenance history shows regular attention to major systems like roofing and plumbing, though there have been clusters of violations suggesting occasional lapses in upkeep that need to be promptly addressed to maintain habitability standards.

Risk rating

How 642-646 Ashbury 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.
