Initial analysis

The 12-unit, 3-story apartment building at 249-253 Duboce Avenue in Mission Dolores, owned by Raul & Denise Arriaza, was constructed in 1907 and has undergone several significant upgrades over its lifetime. Most recently, in 2023, the building received substantial fire safety improvements, including a new fire alarm system with backup features and upgraded smoke detection capabilities at a cost of $18,000. The building's seismic safety was addressed with a soft-story retrofit permit filed in 2017, though there have been ongoing compliance issues; a 2019 complaint noted non-compliance with the Mandatory Soft Story Retrofit Program requirements, which was only marked as "Not Active" in 2024. The building has experienced recurring fire safety system issues, evidenced by multiple fire alarm malfunctions and extinguisher-related complaints between 2014-2022, though most were resolved with appropriate corrections.

The property has several active building violations as of 2023, including issues with gas utility shutoff tools, fire escape maintenance, compliance affidavits, and fire extinguisher date tagging, all originating from an April 2023 complaint. Historical maintenance work includes foundation repairs, window replacements (1999), and various structural improvements. There have been multiple routine inspections and complaints over the years, addressing issues such as electrical concerns, plumbing work, and various maintenance needs. The building's fire safety systems have a history of both malfunctions and prompt corrections, with no reported civilian injuries from any fire incidents. Recent 311 calls from 2024 primarily relate to exterior maintenance issues, including graffiti and debris removal, which were all resolved.

Risk rating

How 249-253 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.
