Initial analysis

The two-unit residential building at 1-3 Coso Avenue in Bernal Heights is a two-story flats and duplex structure built in 1906, currently owned by Christopher Vanpelt. The property has undergone significant recent improvements, including the installation of two new photovoltaic solar systems (3.825 kW and 3.40 kW) in January 2024, replacement of both front siding (July 2023) and rear yard stairs (May 2023), and the completion of a soft-story infill project for storage and door replacement (March 2023). The building has received substantial infrastructure upgrades since 2016-2017, including a complete kitchen remodel, ductwork replacement, bathroom renovations, and HVAC improvements with two new water heaters (2022-2023) and a new furnace. A notable incident occurred in November 2017 when a vehicle struck the front stairs, requiring repairs to the gas line and siding, though these issues were promptly addressed.

The property's maintenance record shows regular updates to fixtures and systems, including bathroom and kitchen renovations, electrical upgrades (including knob and tube replacement), and plumbing improvements. While there have been several building complaints and violations in recent years (2016-2017) regarding mechanical permits and possible illegal units, these issues have been resolved and are no longer active. The building has also received attention from city services for various exterior maintenance needs, as evidenced by multiple 311 calls for cleaning and parking enforcement between 2023-2024. Recent permits and improvements indicate ongoing maintenance and upgrading of the property, with particular attention to safety features like stairs, solar energy systems, and building envelope maintenance.

Risk rating

How 1-3 Coso 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
99th percentile

Out of 1276 buildings in this neighborhood, 13 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 93.1%
Moderate concern 5.3%
Severe concern 1.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
