Initial analysis

The two-unit residential building at 1271 Potrero Avenue, located in the Inner Mission neighborhood, is a two-story flats and duplex structure built in 1915, currently owned by Lech Heisel R. The building has undergone some maintenance work in the past, including stucco replacement with vinyl on the front (1994) and reroofing (1994), and a garage door opener installation in 2008, though this electrical permit has since expired.

Recently, the property has experienced significant maintenance and compliance issues, with multiple active complaints and service requests. Most concerning is an active complaint from March 2024 regarding the building being abandoned/derelict with unaddressed graffiti, and another complaint from February 2022 regarding an improperly installed water heater. The building has been the subject of numerous graffiti incidents throughout 2024, with at least eight documented cases between February and December 2024, affecting both the building and the surrounding sidewalk areas. While some of these graffiti cases have been marked as resolved through inspection or abatement, several remain open as of early 2025. The property has also experienced some construction code violations, with a notable instance in February 2022 where a water heater was reportedly replaced without proper permitting procedures, and the old unit was left on the street. The cumulative nature of these recent issues, particularly the active complaints related to abandonment and persistent graffiti, suggests ongoing challenges with property maintenance and resident experience.

Risk rating

How 1271 Potrero 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 2380 buildings in this neighborhood, 1785 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 complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

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 23.3%
Moderate concern 40.2%
Severe concern 36.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
