Initial analysis

The property at 2315-2317 Mission Street is a three-story mixed-use building constructed in 1900, containing two residential units and retail space, currently owned by Robert C M & Lori O Chiang. The building has undergone several significant improvements and faced multiple maintenance challenges over recent years. Most notably, in late 2023, the building completed an upgrade to its fire alarm system to comply with San Francisco Fire Code requirements, following previous violations in 2021-2023 related to fire safety systems, including alarms and extinguishers. The building has also successfully completed mandatory seismic upgrades as a Tier 4 soft-story retrofit in 2017, improving its structural stability.

The property has experienced recurring water-related issues, with multiple complaints about leaks and water damage between 2015 and 2024, including recent complaints in 2023-2024 about furnace and water heater leaks causing mold growth. A cluster of building violations was recorded in early 2022, including issues with water damage, mold, and smoke detector requirements, though these were abated by July 2022. The building has undergone various unit improvements, including kitchen and bathroom renovations in multiple apartments (2015-2019), and previously addressed interior issues such as dry rot repairs in 2015. The commercial storefront has faced periods of vacancy, particularly noted in 2018-2020. Recent maintenance work includes the installation of a new fire alarm panel and associated devices in December 2023, and the property has shown responsiveness to fire safety compliance requirements, with violations being promptly addressed once cited.

Risk rating

How 2315-2317 Mission 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 2380 buildings in this neighborhood, 2190 are predicted to be safer.
