Augrented Insights

Initial analysis

The two-unit, two-story residential building at 4214-4216 18th Street, owned by Larry Kenneth Hetrick Jr., was constructed in 1904 and has undergone several significant improvements over the past two decades. The property has experienced multiple concerning incidents and ongoing compliance issues in recent years, with active building complaints in 2024 regarding unauthorized work and unsafe conditions, as well as complaints about an allegedly excessively tall rear fence constructed in 2023. The building's maintenance history includes several permitted improvements, such as a substantial kitchen remodel and hardwood refinishing in 2021 ($22,000), sewer lateral replacement in 2018, and electrical upgrades in 2019 including the replacement of a fuse panel with a circuit breaker panel. Earlier maintenance work included a reroofing project in 2005 and dry rot repairs in 1994.

The property has a concerning pattern of fire safety violations, particularly between 2015-2020, including multiple instances of blocked exits and problems with doors, hardware, and fire extinguisher service requirements. While these violations were eventually abated, they indicate past safety concerns. Additionally, recent building complaints from 2022-2024 suggest ongoing issues with unauthorized modifications and work beyond permitted scope. The building's surroundings have been the subject of various 311 calls in late 2024, primarily relating to street cleaning, graffiti, and noise issues, though these appear to be more related to the neighborhood rather than the building itself. The property has undergone various permitted improvements over the years, including attempts to improve safety features, though recent complaints suggest potential ongoing concerns with unpermitted modifications and maintenance practices.

Risk rating

How 4214-4216 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.

Neighborhood percentile

35th percentile

Out of 1278 buildings in this neighborhood, 831 are predicted to be safer.
