Initial analysis

The two-story, five-unit multi-family residential building at 1339 16th Avenue in the Inner Sunset, owned by Aqua Horizons LLC, was constructed in 1924 and has undergone significant safety and modernization improvements in recent years. Most notably, the building completed mandatory soft-story seismic retrofit work (as a Tier 4 building) in 2020, along with comprehensive fire safety upgrades including the installation of sprinklers throughout the building between 2021-2022, fire alarm system enhancements, and related plumbing and electrical work totaling over $100,000 in documented improvements. The property underwent substantial interior reconfigurations in 2019-2020, including the conversion of an old gym space to an Accessory Dwelling Unit (ADU), modifications to Unit #2, and changes to common areas including bike parking and laundry facilities.

Recent tenant complaints and violation history indicate several previous maintenance and safety concerns, particularly between 2001-2011, including issues with fire escapes, weatherproofing, and flooring in Unit #4 - though all these violations were officially abated by 2002-2011. There were also several construction-related disputes in 2020-2022, including concerns about unpermitted work and compliance with COVID protocols, though most recent work appears to have proper permits. A notable tenant buyout occurred in October 2022, with an offer of $25,000 to one tenant. The building has experienced occasional false fire alarms or system malfunctions, though no actual fire incidents have been recorded. Recent completion of multiple safety and infrastructure upgrades, including a new main sewer line and electrical panel replacement in 2022, suggests the building is currently maintaining proper compliance with safety codes, though past tenant complaints indicate some recurring issues with communication about utility service interruptions.

Risk rating

How 1339 16Th 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.
