Initial analysis

The 18-unit, three-story apartment building at 1875 Buchanan Street in Lower Pacific Heights, owned by Ashizawa Mark and constructed in 1989, has undergone several significant safety and maintenance upgrades over the past decade. Most recently, in December 2023, a violation was issued regarding sleeping area requirements that remains open as of October 2023, and there are currently filed permits for adding low frequency horns in sleeping areas (November 2024) and a fire alarm upgrade (June 2023). The building has experienced recurring fire safety system updates, including a 2019 incident related to exit maintenance and multiple smoke/CO detector activations, with the most recent fire violation indicating noncompliance in sleeping area requirements.

The property has maintained active attention to structural and safety concerns, with significant work performed on hallways, guardrails, and fire safety systems. Notable improvements include a hydronic boiler replacement in 2019, power system upgrades in 2016, and comprehensive fire alarm system updates in 2013 costing $17,400. Historical records show earlier maintenance addressing dry rot issues in 2000, window replacements in 2009, and deck repairs. The building has undergone routine inspections by Housing Inspection Services in 2000, 2010, and 2016, with all violations from the 2016 inspection being abated by February 2016, including issues related to carbon monoxide and smoke alarms, structural maintenance, and auxiliary lighting. While there have been multiple fire-related incidents, none resulted in injuries or significant damage, with most being false alarms or system malfunctions. The property has also experienced various maintenance matters in the surrounding area, including recent issues with traffic signals, street cleaning, and graffiti, though these are external to the building itself.

Risk rating

How 1875 Buchanan 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
17th percentile

Out of 670 buildings in this neighborhood, 556 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.

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.

Owner's portfolio size

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

12-Month severity forecast
No violation 40.8%
Moderate concern 44.4%
Severe concern 14.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
