Initial analysis

The property at 3319 Clay Street is a two-unit, two-story multi-family residential building located in Presidio Heights, built in 1910 and currently owned by Thompson Street Trust. The building underwent significant renovations in 2016-2017, including a complete upper unit remodel featuring a new kitchen, three bathrooms, and one powder room, along with extensive electrical rewiring and plumbing upgrades costing approximately $200,000. The renovation work did experience some controversy, with a building violation filed in December 2016 regarding unpermitted construction, though this was eventually abated by December 2018. More recent improvements included the installation of new stairs, a sliding skylight, a redwood roof deck, and upper unit furnace replacement in 2017.

The building's infrastructure improvements included complete electrical rewiring, plumbing upgrades with new water heaters, and heating system modifications. Outside the building, there have been recurring issues with tree roots damaging the sidewalk, with three reports in 2023 and one sidewalk defect report in 2020 that remains open. Parking-related incidents have been documented through 311 calls, including illegal parking cases in 2018 and 2021, while a 2017 roof-related permit was filed with minimal associated cost. A 743 smoke detector activation incident was recorded with no injuries or fire damage noted. The building's earlier history shows reroofing work completed in 1992 and 1993, though permits for these projects are now expired.

Risk rating

How 3319 Clay 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
64th percentile

Out of 181 buildings in this neighborhood, 65 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.

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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 81.0%
Moderate concern 12.5%
Severe concern 6.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
