Initial analysis

The 12-unit multi-family residential building at 3010 Buchanan Street in Cow Hollow, owned by Perkins Sonja Hoel Trustee, has undergone significant updates and improvements since its 1963 construction. The property has seen major modernization efforts, particularly in unit renovations, with completed upgrades in Units 4, 5, 12, and 3 between 2020-2022, including kitchen and bathroom remodels, flooring replacements, and electrical system improvements. A comprehensive fire safety upgrade was implemented in 2021-2023, including the installation of low-frequency sounders, a new fire alarm control panel, and associated system modifications to meet current safety codes, with the most recent work completed in March 2023 including lobby annunciator installation.

The building's maintenance history shows regular updates to essential systems, including electrical panel replacements for multiple units in 2019, and plumbing upgrades in 2023 for Unit 12. Several fire alarm system complaints were recorded between 2006 and 2021, though all were marked as "Condition Corrected" or "No Merit." The most recent fire-related incidents were mostly routine system activations or false alarms, with no civilian injuries reported. The property has maintained good compliance with housing standards, with only two routine inspections noted in 2000 and 2006, and no active violations since then. Recent infrastructure maintenance has focused on individual unit upgrades and fire safety improvements, suggesting ongoing investment in building systems and resident safety.

Risk rating

How 3010 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

Out of 861 buildings in this neighborhood, 758 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.

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 61.9%
Moderate concern 23.6%
Severe concern 14.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
