Initial analysis

The 6-unit multi-family residential building at 1901-1919 Taylor Street in Russian Hill, owned by Giampaolo Boschetti, was constructed in 1924 and has experienced several significant maintenance and safety events over its history. The building underwent important seismic retrofitting in 1990 with the installation of anchor bolts in the mudsill, and more recently, improvements were made including a dedicated car charger circuit installation in 2019 and utility pole work in 2014. Several heating-related complaints were documented, with notable issues in 2005 and 2008 when tenants reported inadequate heat and failure to maintain required temperatures, though these violations were eventually abated. A pattern of maintenance concerns emerged in 2005, including fire safety issues (fire escape ladder repair, basement storage compliance), security violations (exterior door self-closing devices, deadlatch locks), and heating problems, all of which were addressed by January 2008.

More recent tenant complaints have raised concerns about building conditions, including a 2018 report about window safety and heating issues, and a 2020 complaint regarding recycling container placement blocking a fire exit. The property has maintained some level of ongoing maintenance activity, as evidenced by multiple building permits for reroofing (1996) and street space work (2010), as well as regular 311 calls regarding parking and street conditions in the vicinity. The most recent planning record indicates installation of antenna and equipment boxes by ExteNet Systems. While the property has experienced various maintenance challenges over the years, most violations have been resolved, though some recent complaints suggest continued attention to building condition is warranted.

Risk rating

How 1901-1919 Taylor 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 1133 buildings in this neighborhood, 884 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.

NOV rate, owner's portfolio

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

12-Month severity forecast
No violation 43.7%
Moderate concern 49.9%
Severe concern 6.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
