Initial analysis

The three-unit residential building at 31-35 Lyon Street in the Haight Ashbury neighborhood, owned by Holmes Robson S Est Of, has a history dating back to its 1908 construction. The property underwent significant repairs in 2003 following several violations documented during a routine inspection, which revealed multiple safety concerns including loose handrails at the front entrance stairs, deteriorating rear stairs, security issues with exterior doors, and combustible storage problems. These violations were all addressed and abated by July 2003, though some were re-identified in a 2008 routine inspection. More recently, the building received maintenance attention with the replacement of a 75-gallon water heater in August 2023.

The building's maintenance history shows attention to structural elements, including street space permits in 2014 and 2016, rear stairs repairs in 2003, and earlier work on terrazzo steps in 1997 and re-roofing in 1989. The property has experienced recurring issues with unauthorized parking on nearby sidewalks, with multiple 311 calls documented between 2020 and 2024, suggesting a persistent parking enforcement challenge in the area. Recent maintenance needs outside the building have been addressed, including graffiti removal (2020, 2018) and various street maintenance issues. The building's record shows active management addressing both routine maintenance and more serious safety concerns, though the age of the building continues to warrant regular upkeep as evidenced by the recent water heater replacement.

Risk rating

How 31-35 Lyon 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 581 buildings in this neighborhood, 232 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 63.1%
Moderate concern 20.6%
Severe concern 16.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
