Initial analysis

The two-unit residential building at 4426 18th Street in the Eureka Valley/Dolores Heights neighborhood, owned by the Loyar Holtz Revocable Trust, was constructed in 1927 as a two-story flats and duplex structure. The building's maintenance and safety history raise several concerns, most notably a serious building complaint from January 2013 that reported multiple issues including inoperative electrical systems, lack of heat, unauthorized unit modifications, and a gas leak in the main building. While this complaint is listed as "Not Active," there is no clear indication of resolution. The only electrical upgrade on record, completed in 2006, involved a garage service installation of 175 amps with three meters for tenant and house use.

The property has experienced ongoing neighborhood maintenance challenges in recent years, particularly in 2023-2024, with multiple 311 calls documenting issues such as graffiti (both on the building and adjacent sidewalk), garbage and debris, and sidewalk cleaning needs. While many of these cases have been resolved by various city departments, including DPW and Recology, they indicate persistent exterior maintenance challenges. There are also several recent encampment-related calls in early 2025, though these appear to be more related to the immediate vicinity rather than the property itself. Two parking-related signs were reported as defaced in February 2023, though these were also resolved. The building's records also show a closed case regarding short-term vacation rental usage and a record request filed by Matt Watkins, though the nature of this request is not specified in the available data.

Risk rating

How 4426 18Th 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.

Out of 1278 buildings in this neighborhood, 460 are predicted to be safer.
