Initial analysis

The two-story, four-unit multi-family residential building at 79-85 Delmar Street in Haight Ashbury, owned by Raul & Denise Arriaza, was constructed in 1904 and has undergone several significant repairs and improvements over the years. Most recently, in September 2021, the property required substantial plumbing work including repairs to a sewer line connecting the backyard to the hallway, which extended approximately 30 feet. These repairs, totaling $5,000, were successfully completed and represent the building's latest major infrastructure work. The property experienced a notable series of violations in September 2004, when multiple safety and maintenance issues were documented including problems with the central alarm system, smoke detectors, fire extinguishers, stairs, handrails, combustible storage, and garbage management. These violations were formally recorded through a notice that included multiple citations under various housing codes. All of these violations were abated by November 22, 2004, along with an additional complaint regarding an unpermitted stair replacement. Earlier maintenance history includes roofing work permitted in 1997, stair repairs in 1995, and a smoke detector installation in 1989.

More recently, the property has generated several 311 calls primarily related to parking enforcement issues, with multiple citations issued in 2024 for driveway blocking incidents. There have also been reports of waste cleanup needs on the street near the property, with several such cases documented in October 2020 and one in July 2022. The building's overall maintenance history shows attention to necessary repairs, though the 2004 violation cluster indicates there were periods requiring significant intervention to address safety and maintenance issues. The most recent building permit activity (2021) suggests that the property has received appropriate attention to necessary infrastructure repairs in recent years, though the age of these repairs is worth noting relative to current building standards.

Risk rating

How 79-85 Delmar 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, 337 are predicted to be safer.

Model explanation

What's driving this score

Number of units

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Building size

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