Initial analysis

The two-unit, three-story multi-family residential building at 731-733 Vermont Street in Potrero Hill, owned by James K Mackey, was constructed in 1910 and has undergone several significant maintenance and improvement projects over the years. In 2005, substantial roofing work was completed at a cost of $23,740, including the removal of composition and wood shingles and installation of new plywood sheathing, along with the installation of solar modules and a solar inverter system on the roof. Earlier maintenance included window repairs completed in 1996. A safety concern was documented in 1997 regarding insufficient railing height in the stairwell, though this issue was ultimately resolved.

In recent years, the property has experienced recurring sewer system issues, with two documented sewage back-up incidents in late 2024 from the side sewer vent. The building's surrounding area has faced various municipal service issues, including an open encampment cleanup case (as of September 2023), multiple reports of abandoned vehicles in 2024, and infrastructure concerns such as a damaged tree (October 2024) and an overflowing city garbage can (May 2024). While the majority of these external issues have been resolved through appropriate city departments, they indicate ongoing challenges in the immediate vicinity of the property. The building's maintenance record shows attention to both structural and environmental improvements, particularly with the addition of solar technology in 2005, though recent plumbing system concerns may warrant monitoring.

Risk rating

How 731-733 Vermont 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
73th percentile

Out of 726 buildings in this neighborhood, 196 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 72.6%
Moderate concern 21.2%
Severe concern 6.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
