Initial analysis

The three-story multi-family residential building at 46-48 Pierce Street in Hayes Valley, owned by Paul C. and Helene Kocher, was constructed in 1900 and contains two units. The property has undergone significant renovations and improvements over the years, with the most substantial work occurring in 2009 when a major remodeling project valued at $384,000 was completed, involving the relocation of unit #46 from the first floor to the basement, foundation replacement, and various interior modifications across all floors. This renovation was accompanied by comprehensive updates to the building's systems, including the installation of a radiant heating system, new electrical panels and wiring, and plumbing infrastructure. More recent improvements include the 2017 replacement of 18 visible rear windows, maintaining their original design and size, and the installation of solar PV panels on the roof in 2010.

The building's maintenance history shows attention to structural issues, with dry rot repairs completed in 2005 and various window replacements undertaken as part of the ongoing upkeep. The property has been regularly updated to meet modern standards, including the installation of smoke detectors throughout and various system upgrades. Recent 311 calls from 2024 primarily relate to outside maintenance issues such as graffiti and encampments in the vicinity, which have been addressed by the appropriate city agencies. The building's permit history demonstrates a pattern of proactive maintenance and system upgrades, with most major improvements having been completed successfully, though some permits from 2010 show as expired.

Risk rating

How 46-48 Pierce 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
69th percentile

Out of 1027 buildings in this neighborhood, 318 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

12-Month severity forecast
No violation 59.7%
Moderate concern 14.1%
Severe concern 26.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
