1966 California St

Pacific Heights, SF 94109 0640008 13 units · 3 fl · 1922

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. 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 1966 California 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 O'Connor Family Trust owns the 13-unit, 3-story, 1922 apartment building at 1966 California Street in Pacific Heights, which has undergone significant improvements and maintenance to enhance resident safety and amenities over the past several years. Most notably, the building completed a mandatory soft-story retrofit (Tier 3) in 2015, installed a comprehensive fire sprinkler system in 2016-2018, and upgraded the fire alarm system multiple times including a 2023 modification to meet current code requirements. The property has undergone various mechanical improvements, including the installation of a new hydronic boiler system in 2018, replacement of steam heating systems, and updates to electrical service including a 400-amp underground service upgrade in 2016.

The building's renovation history shows substantial work to bring the property into compliance with current building codes, including the legalization of an 824.8 square foot unit on the first floor in 2016-2017 and updates to multiple individual units. While there have been several building violations and complaints over the years, most were addressed promptly, with the most recent fire system-related complaint in 2023 being corrected within three weeks. Historical issues from the 2000s regarding heating systems and fire safety were resolved, and there have been no active violations related to these concerns in recent years. The property has shown a commitment to maintaining safety systems, as evidenced by regular fire alarm and sprinkler system maintenance, though there have been periodic issues requiring attention, including multiple fire system-related complaints/violations from 2007 through 2023. Recent complaints have primarily been related to parking issues outside the property, as recorded in 311 calls, rather than internal building maintenance or safety concerns.

Risk rating

How 1966 California 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
18thpercentile

Out of 963 buildings in this neighborhood, 790 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
