Initial analysis

The three-unit, two-story multi-family residential building at 618-622 Carolina Street in Potrero Hill, constructed in 1907 and currently owned by James Richardson 2006 Living Trust, has undergone several significant renovations and faced multiple safety concerns over the years. Recent activities include two reroofing projects in 2024 with costs of $9,000 and $12,000, and a completed sidewalk housetrap installation in 2021. The building's history shows substantial work in the mid-2000s, including structural revisions with shear walls and beams in 2005 ($15,000), exterior improvements in 2004 ($40,000), and a significant interior remodel of the second-floor unit in 2006 ($50,000). Notable compliance issues arose in 2005-2006 when there were violations for exceeding approved work scope, particularly regarding foundation work and top floor renovations, which were ultimately resolved by 2010.

Recent fire safety concerns have been persistent, with multiple alarm system violations recorded between 2019 and 2023, including a pattern of unintentional transmissions, system malfunctions, and a blocked exit in May 2023 where no access to the building was reported. These violations have been generally corrected, though a violation for hazardous materials was recorded in late 2022. The property has also experienced recurring garbage and debris issues, as evidenced by multiple 311 calls in late 2024, typically involving overflowing city garbage cans and abandoned items. The building's documented history includes a brief investigation in 2002 regarding an allegedly illegal third unit, which was resolved within one day, and various infrastructure improvements including electrical system upgrades, plumbing work, and sidewalk maintenance. While many historical violations have been resolved, the ongoing pattern of fire safety concerns and recent waste management issues may be of interest to potential residents.

Risk rating

How 618-622 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, 319 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 48.6%
Moderate concern 38.4%
Severe concern 13.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
