Initial analysis

The 10-unit multi-family residential building at 661-675 Cole Street in Haight Ashbury, owned by Arielle Claire Olszer, has undergone significant improvements since its construction in 1961, with particular attention to safety and modernization. Most recently, in 2023, the building received a fire alarm upgrade (cost: $28,860) and experienced plumbing improvements including a water heater replacement (75-gallon) and the addition of a heat pump in Unit 8. The building completed its mandatory soft-story retrofit in 2015 (cost: $118,000) to comply with SFBC Chapter 34B requirements, achieving Tier 3 compliance. Substantial renovations were performed in 2007-2008, including exterior facade upgrades, addition of storage facilities, and kitchen/bathroom remodels in multiple units, along with extensive electrical work involving the installation of new lighting, switches, and receptacles.

The building has maintained an active approach to addressing safety concerns, with three fire safety-related complaints (2018, 2017, 2011) resolved promptly, indicating good responsiveness to safety issues. Historical violations from 2006 related to fire escape maintenance and weather proofing were all abated by November 2006. Recent 311 calls primarily relate to street-level issues such as parking violations and graffiti, which are not directly related to building conditions. The property has demonstrated regular maintenance and upgrades, including multiple water heater replacements, electrical system improvements, and unit-specific renovations, suggesting active management and investment in building upkeep.

Risk rating

How 661-675 Cole 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 581 buildings in this neighborhood, 540 are predicted to be safer.

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.

Number of units

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

Building size

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 42.7%
Moderate concern 18.7%
Severe concern 38.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
