Initial analysis

2301 Bay Street is a three-story, 18-unit multi-family residential building constructed in 1927 and owned by Trm Bay Lp, located in San Francisco's Marina neighborhood. The property has undergone significant safety upgrades in recent years, including a fire alarm system upgrade in 2023 (cost: $38,655) to comply with current fire safety requirements, and completed soft-story seismic improvements in 2016-2017 (cost: $81,000) that included the installation of moment frames and shearwalls, bringing the building into compliance with San Francisco Building Code requirements. Other major improvements include vinyl siding installation in 2022 (cost: $39,785) and regular unit upgrades, with multiple apartments receiving comprehensive renovations to kitchens, bathrooms, and electrical systems between 2006 and 2012.

The building has experienced several maintenance issues over time, with the most recent concerns including a defective house trap reported in May 2023 and an asbestos complaint in October 2022. Historical violations from 2002-2006 included various fire safety and heating system issues, all of which were resolved. The property has triggered multiple fire department responses, primarily for system activations and false alarms, though there have been no recorded civilian injuries. Recent routine inspections have generally shown compliance with safety standards, with the most recent fire exit maintenance issue from January 2024 being promptly corrected. While there have been some plumbing and heating system concerns in the past, including a water heater leakage issue in 2015, these have typically been addressed through appropriate permits and repairs. The building's maintenance history shows regular attention to safety upgrades, with particular focus on fire systems and seismic compliance, though some periodic issues with parking violations and garbage management have been documented through 311 calls.

Risk rating

How 2301 Bay 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.
