Initial analysis

The three-story, 4-unit multi-family residential building at 1347-1349 Folsom Street in San Francisco's South of Market neighborhood, owned by Castro LLC, has undergone several significant structural and safety improvements since 2023. Most notably, in April 2023, the building received substantial voluntary strengthening work on the ground floor and basement, including ADA upgrades and the installation of shear walls and Simpson wood panels, costing $65,000. However, recent building violations from March 2024 raised serious concerns about habitability, including lack of heat, egress obstructions, floor covering issues, window damage, mold, and general building maintenance problems, all of which were abated by March 27, 2024. The property is also subject to ongoing concerns about plumbing and electrical systems, with a May 2024 complaint regarding a faulty bathroom faucet and previous heat system issues. Historical records indicate various maintenance challenges, including reports of pests (2011), unauthorized construction work (2001), and recurring heat system problems (2004). Recent improvements include the installation of a tankless water heater in 2011 and the 2023 structural upgrades, though a significant number of permits from the late 1990s to early 2000s show various expiring or withdrawn applications for unit remodeling and maintenance work. A concerning pattern of complaints about building conditions and maintenance issues emerges from both recent and historical records, suggesting ongoing challenges with property upkeep and tenant services.

Risk rating

How 1347-1349 Folsom 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.
