Initial analysis

The two-unit residential building at 501-503 Cole Street in Haight Ashbury, owned by Michael Schonberg and El Helf, has undergone significant renovations and faced multiple maintenance challenges since its construction in 1900. Major improvements between 2011-2018 included comprehensive plumbing upgrades with the installation of fire sprinklers, central heating systems, and extensive electrical work comprising new panels and circuits for both units, though many permits from this period expired before completion. A series of building complaints from 1996-2018 raised concerns about safety features and maintenance issues, including problematic stairs, windows, and an illegally constructed unit in the garage, though these complaints were marked as not active. Recent activity (2023-2024) has primarily involved either parking-related enforcement actions or maintenance issues outside the building, such as tree root damage affecting the sidewalk and a defective curb condition, both of which remain open as of February 2024.

The property has a documented history of construction activity since 2009, with a complaint filed in June 2018 about continuous construction and unauthorized work permits. More recent permits from 2018-2020 focused on obtaining final inspections for previously completed work, including plumbing and electrical systems. Two fire incidents were recorded, though neither resulted in civilian injuries. Current concerns primarily revolve around infrastructure maintenance, with multiple 311 calls reporting issues like parking violations, garbage, and tree-related problems in 2024. A proposed plan for replacement and construction of deck/stair structures at the rear of the building was submitted but was ultimately withdrawn.

Risk rating

How 501-503 Cole 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
81th percentile

Out of 581 buildings in this neighborhood, 110 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 75.1%
Moderate concern 13.4%
Severe concern 11.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
