Initial analysis

The property at 139-141 Pfeiffer Street is a three-story, two-unit multi-family residential building constructed in 1906, currently owned by the Guichet Family Trust. The building has undergone several significant renovations and safety upgrades over the years, most notably in 2016-2019, when substantial improvements were made including the addition of an upper floor and roof deck, complete interior remodels of kitchens and bathrooms, installation of a comprehensive fire sprinkler system, total rewiring of the house with new sub-panels, and the implementation of radiant heating. The roof deck addition in 2016 sparked a building complaint about permit violations and safety concerns, though this issue was ultimately resolved. Earlier complaints from 2000-2001 regarding unauthorized deck and stair construction were also addressed and abated.

More recent improvements include street space and sidewalk work in 2019, and the resolution of a lead paint safety violation in 2013. The building's major systems were thoroughly upgraded during the 2018-2019 renovation period, including plumbing improvements with new kitchen sinks, laundry facilities, and bathroom fixtures, though some permits were marked expired. The property has experienced minimal recent issues, with only routine municipal service calls recorded in 2023 relating to street cleaning activities. Historical records show a brief period in 1997 when there was a complaint about garage use for business purposes, but this was promptly resolved. The building's significant renovation period from 2016-2019 appears to have brought it up to modern safety and compliance standards, with particular attention paid to fire safety through the installation of a complete sprinkler system with monitoring controls, and comprehensive electrical and plumbing upgrades throughout the property.

Risk rating

How 139-141 Pfeiffer 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
99th percentile

Out of 684 buildings in this neighborhood, 7 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 age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

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 92.2%
Moderate concern 5.0%
Severe concern 2.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
