Initial analysis

The 2-story multi-family residential building at 1200 18th Street in Potrero Hill, owned by the Anna Stern Trust, was constructed in 1928 and contains 3 units. The property has undergone significant recent improvements, including a completed bathroom remodel in Unit C in July 2024 costing $45,000, installation of a new private elevator in 2018-2019, and various bathroom renovations. Notable safety improvements were completed in 2007-2008 following a physical inspection report, including the replacement of fire-rated doors and repairs to stairway framing and ceilings. The building's electrical system has received multiple upgrades, including a new 150-amp main panel installation and Tesla charger in 2015, and substantial common area lighting improvements in 2019.

The property has a history of routine safety inspections dating back to 1999, all of which have been successfully resolved. Regular maintenance work has been documented, including reroofing in 2009 and compliance with multiple inspection requirements. Recent 311 calls related to the property have primarily concerned external issues such as sidewalk maintenance and street cleaning, with no significant safety concerns reported. The building's management has generally maintained compliance with city requirements, as evidenced by the successful resolution of all building complaints and inspections. Historical planning records indicate previous proposals for condo conversion and deck construction, though it's unclear from the records whether these were ultimately implemented.

Risk rating

How 1200 18Th 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, 348 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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 69.2%
Moderate concern 22.9%
Severe concern 7.9%
