Initial analysis

The property at 150 Harold Ave is a two-unit, two-story multi-family residential building located in the Ingleside neighborhood, constructed in 1910 and currently owned by Joseph Cho Lau. The building has undergone several repairs and maintenance projects over the years, with the most recent work occurring in April 2023 to address dry rot issues in ground floor storage rooms, though there is currently an active complaint filed in April 2023 regarding unauthorized construction of an additional two-story structure behind the main house. A previous permitted project in 2020 to repair drywall and repaint two bedrooms was cancelled, while a successful stucco replacement and repair project was completed in 2002.

The property has experienced an unusual cluster of recent issues from November 2024 through December 2024, with multiple reports of garbage and debris on the property and surrounding areas, including at least five separate incidents of abandoned items that required Recology intervention. There were also two parking-related incidents reported during this period, including a driveway blockage that resulted in a citation. While these recent exterior maintenance issues are concerning, they appear to be primarily related to waste management rather than structural or safety concerns. The building's rental status was verified through a Rent Board inquiry in November 2024, confirming that there is a housing opportunity (HO) on file with no fees owed for the 2025 cycle. The property has had no recorded tenant buyouts, and the most recent documented tenant relocation involved two units at 61 Edgar Place in July 2022 for a sum of $66,711.54, though this is unrelated to the current property.

Risk rating

How 150 Harold 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

Out of 156 buildings in this neighborhood, 117 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

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 69.3%
Moderate concern 23.1%
Severe concern 7.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
