Rent & eviction protection

Is 70 Onondaga 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 1958
2 or more units

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 1958
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 multi-family residential building at 70 Onondaga Ave in Mission Terrace, constructed in 1958, has experienced several significant maintenance and safety issues over its history. Most recently, in September 2024, there was a complaint regarding unauthorized window replacement work, with reports of scaffolding and debris issues, though this was eventually followed by a proper window replacement permit in September 2024. In late 2021, multiple significant violations were documented, including problems with automatic fire sprinklers, damaged walls, rodent infestation, and complaints about window frames, insulation, and wall rot. These violations were marked as abated by April 2022. Earlier, in 2001, the building faced multiple safety violations concerning fire safety equipment, door security, combustible storage, and egress obstruction, which were addressed within a month.

Recent records from late 2024 show several calls regarding garbage and debris removal, though these are primarily related to street maintenance rather than building-specific issues. The building has undergone some proper maintenance work, as evidenced by the completed window replacement permit in 2024, though this followed an unauthorized replacement incident. The property has had three documented fire-related incidents between 2013-2015, all of which were determined to have "No Merit" upon investigation. A tenant buyout occurred in January 2022 involving one tenant for $20,000. The building's recent history has shown a pattern of deferred maintenance issues being addressed primarily through violation processes, with some work being done without proper permits, as evidenced by the September 2024 complaints.

Risk rating

How 70 Onondaga 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
10thpercentile

Out of 149 buildings in this neighborhood, 134 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
