Initial analysis

The two-story multi-family residential building at 4542-4544 Cabrillo Street in San Francisco's Outer Richmond neighborhood was built in 1947 and contains three units with a commercial space, currently owned by San Wai Oo & Khin Sandi Shi. The property has undergone significant improvements in recent years, most notably the legalization of a first-floor dwelling unit in 2018-2019 (completed in March 2018 with a cost of $160,000), followed by comprehensive fire safety upgrades including the installation of 18 sprinkler heads and a monitoring system in 2019-2020 ($15,000 plus $3,500).

Recent concerns have centered around water damage and mold issues, with two complaints filed in February 2023 regarding persistent water intrusion and black mold in the common areas, particularly in the hallway between the front entrance and patio exit. These violations were documented on February 2, 2023, and though officially abated by March 17, 2023, they indicate recent maintenance challenges. The building underwent substantial interior improvements in 2019-2021, including electrical system upgrades (200-amp service), plumbing updates (new bathroom, kitchen, laundry facilities), and window replacements at the rear of the building. Historical records show earlier improvements including a complete reroofing in 2008 and electrical service upgrade in 2004.

Risk rating

How 4542-4544 Cabrillo 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.
