Initial analysis

The two-unit residential building at 15-17 Holloway Avenue in the Ingleside neighborhood is a two-story flats and duplex structure, built in 1908 and currently owned by Lam Alton F. The property has undergone several notable changes and faced various maintenance issues over the years. Most recently, in December 2022, there was a proposed renovation project to convert a laundry room into a bathroom with washer and dryer facilities, estimated at $30,000, though this permit remains in filed status. The building's infrastructure was notably improved in early 2004 with a complete electrical service upgrade to 100 amps with two meters, while two significant staircase repairs were documented that same year, including an exterior front staircase dry rot repair (completed) and rebuilding of damaged stairs (also completed).

The property has experienced multiple maintenance and safety events in its recent history, with the most concerning being a sewage backup incident in September 2021 that was eventually resolved by PUC Sewer Operations. There have also been recurring issues with parking violations in the vicinity, particularly in 2021, with several incidents of vehicle parking on sidewalks and blocking driveways resulting in enforcement actions. Environmental concerns were noted in early 2022, with two separate hazardous materials incidents involving liquid spills documented and resolved by DPW Operations. More recent exterior maintenance issues include an open case regarding a defective curb or curb ramp reported in September 2021, though this remains unresolved as of the latest data.

Risk rating

How 15-17 Holloway Ave'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
85th percentile

Out of 156 buildings in this neighborhood, 23 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Building age

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

12-Month severity forecast
No violation 59.3%
Moderate concern 22.1%
Severe concern 18.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
