Initial analysis

The three-story, five-unit multi-family residential building at 3436-3438 16th Street, owned by the Trigonis Family Trust, has undergone several significant improvements since its construction in 1902. Most recently, in 2020, the building received substantial updates including kitchen and bathroom renovations, installation of a tankless water heater, and electrical upgrades to one bedroom unit with a new sub-panel. A critical seismic retrofit was completed in 2015 at a cost of $50,000, addressing the building's designation as a Tier 3 soft story structure. The building has a history of addressing maintenance and safety requirements, including a 1997 exterior renovation with siding replacement and door updates, and earlier repairs to rear stairs in 1993.

The property has experienced three routine inspections that identified various safety concerns which were subsequently addressed and abated, including issues with fire safety equipment, security devices, and a handrail repair in 2006. While there was a carbon monoxide detector activation incident recorded, no actual CO was present and there were no civilian injuries reported. Recent 311 calls from 2024 primarily relate to street maintenance issues outside the building, including reports of garbage debris, abandoned vehicles, and street lighting problems, though these do not directly pertain to the building's condition or safety. The building has maintained compliance with mandatory soft story retrofit requirements since the initial violation notice in 2019, with the work completed and the matter closed in December 2021.

Risk rating

How 3436-3438 16Th 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
