Augrented Insights

Initial analysis

The two-story, 8-unit multi-family residential building at 835-845 Treat Avenue, built in 1900 and currently owned by the Guzman Carmen Trust, has undergone several significant maintenance and safety improvements over the years. Most notably, the building completed a seismic soft-story upgrade in 2015 costing $95,000, received a new roof in 2007, and has maintained its systems with various updates including recent plumbing work in 2024 involving heater replacement. The property has faced several safety and maintenance challenges, particularly in 2023-2024, including multiple building code violations related to fire safety equipment, gas utility shutoff requirements, and rodent infestation issues, though these were all abated by April 2023. More recent complaints from March 2024 about plumbing issues and heating problems were resolved by May 2024.

The building's maintenance history shows regular attention to critical systems, with historical records indicating previous roof work in 1989 and various permit applications for street space and sidewalk use. While there have been multiple fire safety-related complaints about blocked exits between 2015 and 2019, most were found to have no merit or were promptly corrected. The property has experienced recurring sanitation issues as evidenced by multiple 311 calls regarding garbage and debris in recent months, though these are typically exterior to the building itself. A significant set of violations and complaints was documented in March 2023, including issues with fire escape maintenance, gas utility access, and fire extinguisher tagging, though all were addressed within approximately two months. The building's soft-story retrofit work has been classified as complete with a Certificate of Final Completion issued, indicating compliance with seismic safety requirements.

Risk rating

How 835-845 Treat 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

9th percentile

Out of 2380 buildings in this neighborhood, 2166 are predicted to be safer.
