Initial analysis

The two-unit residential building at 347-349 28th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1924, currently owned by Jennings Christopher B & Go. The property has undergone significant renovations and improvements over the past several years, with substantial work completed between 2019 and 2021. Major structural modifications in 2019 included the removal of a load-bearing wall in the kitchen area and related structural changes, along with comprehensive plumbing updates that installed new water, waste, and gas lines for two kitchens, five full baths, and two laundry facilities. The building received a complete electrical upgrade with a new 400-amp overhead service and wiring throughout.

Subsequent improvements focused on interior comfort and energy efficiency, including the installation of in-floor radiant heating, high-efficiency boiler systems, and gas fireplaces in early 2020. The property has also seen aesthetic upgrades, such as the installation of new flat skylights and windows in 2020-2021. The building's maintenance and improvement history shows regular attention to infrastructure needs, with proper permits obtained and completed for all major work. Recent records from 2022-2024 indicate recurring issues with vehicles blocking driveways, though these are external incidents not directly related to the building's condition or management. The property was also part of a successful condo conversion process, with planning records showing various interior renovations including window replacements and other upgrades, while specifically noting that no wetbar was allowed in the ground floor rooms.

Risk rating

How 347-349 28Th 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.
