Initial analysis

The two-unit residential building at 31-33 Boardman Place, owned by Carlene Foldenauer, is a two-story flats and duplex structure built in 1939 in San Francisco's South of Market neighborhood. The property has undergone several significant improvements over the past two decades, including multiple window replacements (most recently in 2015 and 2011), plumbing upgrades (water heater replacements in 2020 and 2015, and drain pipe replacement in 2011), and a solar panel installation in 2022 consisting of 19 modules with a 7.22 kW capacity. Safety and accessibility improvements have been addressed, including a building code-compliant replacement of the rear exterior stairway in 2003. The property has maintained compliance with building codes, with only one expired permit from 1999 related to garage modifications.

The building's maintenance history shows regular attention to both major systems and exterior maintenance, though there have been periodic issues reported through 311 calls, primarily relating to street cleaning, parking enforcement, and tree maintenance between 2019 and 2024. A notable event in the property's recent history was a tenant buyout at 33 Boardman Place in September 2021, involving 3 tenants and compensation of $96,000. While there was one fire complaint filed in 2010, it was investigated and found to have no merit. The most recent building-related activities include a moving sign request in December 2023 and the installation of solar panels in 2022, indicating ongoing investment in property improvements. The building's location has experienced typical urban maintenance issues as evidenced by 311 calls, though these appear to be primarily related to street and sidewalk conditions rather than building-specific concerns.

Risk rating

How 31-33 Boardman Pl'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.
