Initial analysis

The 4-unit TIC building at 2355 Bay Street in the Marina district has undergone significant renovations and upgrades over the past five years, with particular attention to safety and modern amenities. Most notably, in 2019-2021, the building received substantial improvements including the installation of a new automatic fire alarm system with sprinkler monitoring ($15,000), conversion of Unit #4's heating system to hydronic/radiant heating, and the installation of multiple fireplaces across units ($30,000). Comprehensive plumbing upgrades were completed in 2018-2019, including work on all bathrooms and kitchens, while electrical systems were modernized with new wiring and lighting in multiple units.

The building's history shows a pattern of addressing code compliance issues and routine inspections, particularly notable in 2000-2006 when several violations were recorded regarding heating, security, and fire safety requirements. These historical issues, including concerns about heat provision and gas utility shutoff tools, were all marked as "Not Active" with final abatement dates in 2006. A 2013 complaint about water heating regulation was also resolved. The property underwent significant renovation work in 2018-2019 including unit-specific improvements and the installation of new safety systems, culminating in a vertical addition with a roof deck and interior renovation of Unit 4. Recent 311 calls recorded primarily relate to street maintenance and environmental services, rather than building-specific issues, suggesting improved property management, while the most recent rent board inquiry in 2024 was resolved regarding fee and housing inventory questions.

Risk rating

How 2355 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.

Neighborhood percentile

Out of 988 buildings in this neighborhood, 622 are predicted to be safer.
