Initial analysis

The property at 101-105 Steiner St is a three-unit multi-family residential building constructed in 1900 in Hayes Valley. The three-story structure, currently owned by the Sager-monberg Revoc Tr, has undergone several significant improvements over the past decade, with the most substantial being a voluntary seismic strengthening project in 2022 costing $74,250 that included the addition of plywood shear walls and concrete grade beams on the ground floor. Other notable recent work includes the replacement of non-wood siding with wood siding on the south side enclosed porch in 2018, third-floor window repairs and building repainting in 2017, and a kitchen and bathroom remodel in 2016.

The building has a documented history of issues requiring attention, particularly in the early 2000s when multiple violations were recorded related to stair and handrail repairs and lead paint hazards, though these were all abated by January 2005. There was also a sewage water pipe issue between the building and an adjacent property in 2000. The property has been actively maintained under the Mills Act Historical Property Contract, with works approved for window improvements, foundation maintenance, and various repairs to preserve its historical character. Recent maintenance records from 2023-2024 show several external issues near the property, including graffiti, tree overgrowth, and curb defects, though these are primarily related to public infrastructure rather than the building itself.

Risk rating

How 101-105 Steiner 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, 288 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.

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 56.8%
Moderate concern 34.7%
Severe concern 8.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
