Initial analysis

The 47-49 Henry Street property, a two-unit multi-family residential building located in Duboce Triangle, was built in 1903 and is currently owned by Ashley B Bakken-martin Revo. The building has undergone significant recent improvements, with major renovations in 2024 including kitchen and bathroom remodels, electrical upgrades, and plumbing work in both units. Specific updates include the replacement of waste and vent piping, installation of a 65-gallon heat pump water heater, and modernization of electrical systems with new sub-panels and 200-amp service. The building's infrastructure has also seen important upgrades, including the replacement of clay sewer lateral with HDPE piping in 2022 and the addition of a new water heater in 2023.

The property has a history of responsiveness to maintenance and safety issues, particularly during a cluster of violations and complaints in 2006 regarding peeling paint, lead hazards, stair repairs, and fire safety concerns, all of which were abated by November 2006. Earlier structural improvements included garage strengthening in 1993 and various facade work in the early 1990s. A notable tenant buyout occurred in August 2021 involving three tenants for $150,000. Recent complaints primarily relate to parking issues on the sidewalk, with several reports in 2024, though these could not be validated by responding officers. A renovation project has been proposed for Unit 47, including kitchen and sunroom modifications with a new deck and exterior stairs, though this is currently on hold. The building's recent record shows substantial investment in modernization and maintenance, with particular attention paid to safety systems and basic infrastructure updates.

Risk rating

How 47-49 Henry 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
68th percentile

Out of 287 buildings in this neighborhood, 92 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.

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.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

12-Month severity forecast
No violation 77.8%
Moderate concern 10.9%
Severe concern 11.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
