Initial analysis

The 9-unit, 3-story apartment building at 789 Carolina Street in Potrero Hill, owned by Marlie, LLC, has undergone significant renovations and faced several maintenance challenges since its construction in 1962. Most recently, in April 2024, Unit 4 received a comprehensive remodel including kitchen and bathroom updates with associated plumbing and electrical work ($35,000). The building has seen substantial safety system improvements, including the installation of a new fire sprinkler system in 2022 covering 11 heads in the ground floor and garage, as well as a new fire alarm system in 2021 with various safety features. However, there have been recurring fire safety concerns, with the most recent violations in May 2024 related to the alarm system maintenance and extinguisher servicing, though these were subsequently abated.

The property has experienced several significant issues affecting resident comfort and safety over the years. In April 2021, there were multiple complaints regarding lack of heat and window installation concerns in Unit 9, which led to inspections and required corrections. During 2019, the building underwent various renovations including kitchen remodels in multiple units, window replacement, and dry rot repairs, though some work was performed beyond the scope of permitted activities. The building's elevator has required attention, with an outage reported in August 2019, and there have been periodic fire safety concerns, particularly regarding extinguishers and sprinkler systems, though these issues were typically resolved promptly. Recent infrastructure work has included the addition of an ADU studio at the ground floor, completed under Ordinance 162-16, and various unit upgrades including window replacement and siding repairs.

Risk rating

How 789 Carolina 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 726 buildings in this neighborhood, 711 are predicted to be safer.
