AI summary

The Thompson Revocable Trust owns this two-story, multi-family residential building located at 309-311 Chestnut Street in Telegraph Hill, which contains three units and was constructed in 1915. The building has undergone significant improvements in recent years, with the most recent major work being the replacement of the water service line from the meter to the garage with copper piping completed in August 2023. During 2018-2019, substantial structural and modernization work was performed, including a ground floor remodel costing $60,000, bathroom and kitchen renovations, and electrical upgrades. A notable addition was completed in 2017, converting a second-floor deck into a family room, which included new lighting, outlets, and a 60-amp sub-panel installation. The building's systems have been regularly maintained, with a new furnace installation and plumbing updates completed in 2019.

The property has a history of routine housing inspections, with the most significant findings occurring during a November 2015 inspection that identified several fire safety concerns, including the need for fire extinguisher updates and the provision of smoke alarm documentation; these violations were all promptly abated by December 2015. The building has undergone multiple unit-specific improvements over the years, including bathroom remodels in Unit #309 (2011) and kitchen remodeling work completed in 2006. More recent maintenance issues have primarily involved external factors affecting the property, such as sidewalk tree root damage (2024), though these are currently being addressed through appropriate city channels. The building's historical records show consistent attention to maintenance and upgrades, with no current active violations or complaints.

Risk rating

How 309-311 Chestnut 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
94th percentile

Out of 684 buildings in this neighborhood, 41 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.

Estimated permit spend (past 7 years)

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

Construction spend, owner's portfolio

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

12-Month severity forecast
No violation 80.0%
Moderate concern 9.5%
Severe concern 10.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
