Initial analysis

The 12-unit multi-family residential building at 800 Duboce Avenue, owned by Batchelor Holdings LLC, is a 3-story structure built in 1919 that has undergone several significant improvements and faced multiple compliance challenges in recent years. Most notably, the building completed a mandatory soft-story retrofit in 2017-2018 (Tier 3) and is currently upgrading its fire alarm system to meet current codes with an $87,756 project in 2024 to install low-frequency alarms in sleeping areas. The building has experienced several maintenance and safety concerns, including plumbing issues in 2023 that required Roto-Rooter intervention for 4" sewer pipe replacement and proper S-trap installation in Unit 101. There have been multiple violations and complaints related to unauthorized work, particularly concerning Unit 304, where unpermitted kitchen and bathroom renovations, including washer/dryer installation, led to several tenant complaints about fumes, water intrusion, and safety concerns in late 2022. The building has also faced repeated fire safety challenges, with multiple fire code violations and system malfunctions documented between 2006 and 2024, including issues with fire escape ladders, fire alarm systems, and blocked exits, though most of these violations have been abated.

Recent history shows ongoing maintenance efforts, including a 2019 reroofing project, a 2021 heating boiler replacement, and various unit renovations. The property has experienced some historical pest issues, with complaints about rodent activity and ants recorded in late 2022. The building's management has faced scrutiny for periodic fire alarm system issues, including a recent 2024 complaint about rooftop door alarm handling during inspections. Multiple 311 calls in late 2024 indicate continuing concerns about building systems and maintenance, including water leaks and illegal parking issues. While the building has generally addressed most violations and completed required safety upgrades, the frequency of unpermitted work and associated tenant complaints, particularly regarding Unit 304, suggests ongoing challenges with ensuring proper construction oversight and communication with residents.

Risk rating

How 800 Duboce 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
3th percentile

Out of 351 buildings in this neighborhood, 340 are predicted to be safer.
