Augrented Insights
Initial analysis

The four-story, 33-unit residential building at 666 Ofarrell Street in Downtown San Francisco, owned by SF Multifamily IV Property, has experienced several significant maintenance and habitability issues, particularly in recent years. Most notably, in mid-2024, Unit 6 suffered multiple concerning problems including drainage issues in the kitchen sink, possible past leak damage in the bedroom, a cockroach infestation, and a substantial water leak that affected electrical systems and led to visible mold growth. These problems prompted multiple Department of Building Inspection (DBI) violations and complaints between 2023 and 2024. The building has a documented history of water-related issues, including a final warning notice in September 2023 regarding mold resulting from water leaks, and a 2023 complaint about a non-functioning stove. Earlier concerns included a 2019 complaint about PG&E electrical work near the building that reportedly involved exposed meters and pipes.

Rent & eviction protection

Is 666 Ofarrell 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.

Built 1924
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.

Risk rating

How 666 Ofarrell 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
19thpercentile

Out of 448 buildings in this neighborhood, 363 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.
