Initial analysis

The 9-unit multi-family residential building at 140 Page Street in Hayes Valley, owned by the Siu Family Revocable Trust, has undergone significant improvements and faced various challenges since its construction in 1925. Most recently, from 2020 through 2023, the property has seen substantial upgrades including the addition of three ADUs (Accessory Dwelling Units) in 2020, comprehensive fire safety improvements in 2022 with an upgraded alarm system and sprinklers, and a completed retrofit of the electrical system including a 400-amp panel upgrade. The building successfully completed its mandatory Soft Story program requirements as a Tier 4 property, achieving CFC Certification.

The property has experienced recurring heating system issues, with multiple complaints about inadequate heat filed between 2007 and 2023, including several incidents in early 2023 where units were reported not maintaining the legally required temperatures. These heating issues were notably cited in a series of violations in 2022, which were eventually abated. Other significant historical violations include various fire safety concerns from 2004 (now abated) regarding combustible storage, fire escape maintenance, and fire extinguisher requirements, as well as a 2018 violation for blocked exits that was promptly corrected. The building has maintained active compliance with safety requirements, evidenced by recent completion of fire system upgrades, though historical issues with the fire alarm system were documented in 2016, 2018, and 2019.

Risk rating

How 140 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
3th percentile

Out of 1027 buildings in this neighborhood, 996 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.

NOV rate, owner's portfolio

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

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 12.8%
Moderate concern 58.9%
Severe concern 28.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
