Initial analysis

The property at 3350-3352 23rd Street in San Francisco's Inner Mission neighborhood is a two-unit, two-story multi-family residential building owned by Lori & Donald Regalia and constructed in 1900. Over the years, the building has undergone several significant improvements, including a substantial garage conversion in 2009 (completed at a cost of $40,000), followed by foundation modifications in 2011. The most recent major work occurred in 2020, involving repairs to the top two steps and risers, costing $2,000. In 2017-2018, the property underwent comprehensive interior improvements, including bathroom and kitchen remodeling with associated plumbing and electrical work, totaling approximately $15,000. The building's electrical system has received attention, including a 2011 underground installation for future panel upgrade and a 2012 exterior service upgrade that ultimately expired.

The property has experienced some maintenance and safety issues in recent years, including two notable complaints: one in 2018 regarding a house trap filled with concrete (plumbing violation), and another in December 2019 alleging illegal change of use related to a nearby school. The building's immediate surroundings have been the subject of multiple 311 calls between October 2024 and January 2025, primarily concerning street cleaning and graffiti removal, though these external issues are not directly related to the building's condition or safety. The property's maintenance record shows regular upkeep and modernization efforts, though the 2013 kitchen and bathroom renovation permit expired, requiring reapplication in 2017-2018 to complete the work.

Risk rating

How 3350-3352 23Rd 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.
