Initial analysis

This 1895 two-story multi-family residential building located at 871 Page Street in Hayes Valley, owned by Takahashi Co Ltd, consists of 9 units and has undergone several significant maintenance and improvement projects over the past two decades. The most recent major work includes a gas meter removal project in 2017 and the installation of a 30-amp circuit for air conditioning in 2018. Between 2015-2016, the building underwent substantial renovations including bathroom and kitchen remodels, electrical upgrades, and plumbing improvements with a total investment of over $75,000, though there were instances of work being performed without proper permits during this period, as documented in a May 2016 complaint.

The building has received regular maintenance attention, including two complete reroofing projects in 2013 costing over $28,000, and significant electrical system upgrades in 2017 involving replacement and rewiring of panels and circuits. Historical records indicate the building originally had 7 units in an RH-3 lot configuration. While there was one building violation filed in 2001 regarding unauthorized construction work, this was resolved by March 2002. Recent maintenance issues have been minimal, though a missing side sewer vent cover was reported and resolved in January 2024. The property has had occasional issues related to external factors such as sidewalk parking violations and street cleaning matters, but these do not directly impact the building's condition or management.

Risk rating

How 871 Page 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 1027 buildings in this neighborhood, 842 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Property class

The assessor's property-class code, which correlates with building type and the violation rates the model expects. This code is grouped with other less-common classes.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 27.8%
Moderate concern 56.6%
Severe concern 15.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
