Initial analysis

The 52-unit, 4-story multi-family residential building at 1684-1688 15th Street in the Inner Mission, built in 1907, is currently experiencing significant maintenance challenges, particularly regarding water issues. Most recently, in March 2024, tenants reported bathroom wall leaks with mold and mushroom growth, which previously appeared as a complaint in 2019, along with additional plumbing problems including a leaking bathroom toilet and ceiling leaks noted in 2013. The building has undergone various maintenance and safety upgrades over the years, including the installation of a full automatic fire sprinkler system in 1989, multiple roof replacements (most recently in 2012), and boiler replacement in 2024. More concerning is the recent series of fire safety violations from 2022-2025, including issues with sprinklers, alarms, and sleeping area requirements, though many of these were appropriately corrected. The building has experienced several water-related problems over its history, with notable plumbing work in recent years including storage tank replacements in 2016 and 2011.

The property has a history of maintenance and safety compliance challenges, particularly regarding fire safety equipment and general building upkeep. In 2019, multiple violations were recorded including problems with fire doors, window hardware, smoke alarms, carbon monoxide detectors, and fire escape maintenance. The building's management has generally responded to violations and complaints, as evidenced by numerous "Condition Corrected" statuses on fire safety violations, though some issues have recurred over time. Recent building permits indicate ongoing structural and safety maintenance, including tiebacks for shoring work scheduled for 2024. The property has experienced relatively few fire incidents, with most being accidental alarm activations or cooking-related situations with no injuries reported. While the building has shown responsiveness to many maintenance issues, particularly fire safety concerns, the recurring nature of water-related problems and the recent spike in fire safety violations suggest ongoing challenges with building maintenance and adherence to safety regulations.

Risk rating

How 1684-1688 15Th 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

3th percentile

Out of 2380 buildings in this neighborhood, 2309 are predicted to be safer.
