Initial analysis

The 6-unit, 3-story apartment building at 139-145 Dore Street in San Francisco's South of Market neighborhood, constructed in 1907, has undergone several significant improvements and faced various challenges over its recent history. Most notably, the building has received substantial safety upgrades, including a complete fire alarm system replacement in 2023 ($47,850), following a cancelled 2022 project that had been initially planned at a cost of $35,169. The property has also been the subject of multiple fire-related incidents, primarily system malfunctions and false alarms, though there have been no civilian injuries recorded in these events. Between 2013-2014, the building underwent significant renovations totaling approximately $480,000, including interior upgrades to all 6 units (new kitchens, bathrooms, fixtures), exterior improvements (vinyl siding replacement, windows upgrade), garage reinforcement work, and electrical system upgrades.

The building has faced some regulatory challenges, including multiple citations related to the mandatory Soft Story Retrofit Program, with violations filed in 2014 and 2017 regarding failure to submit required documentation and permit applications. Several building violations from 2003-2004 were addressed, including issues with lead paint, dryer ventilation, handrails, and guardrails, all of which were subsequently abated. More recent tenant concerns have been documented through 311 calls and complaints, particularly regarding construction noise and unpermitted work in December 2021, as well as a persistent issue with an unpermitted electrical sign in 2015 that reportedly disturbed neighboring tenants. The property has maintained active compliance with plumbing and electrical permits, with recent work including the installation of new central heaters in 2013 and various electrical system upgrades. A pattern of service calls related to the building's elevator system has also been recorded, suggesting this may be an ongoing maintenance area of focus. The most recent electrical work was filed in March 2024, indicating continued infrastructure maintenance and upgrades are being pursued by the current ownership, Yscraper LLC.

Risk rating

How 139-145 Dore 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

Out of 430 buildings in this neighborhood, 262 are predicted to be safer.
