Initial analysis

The three-story, six-unit multi-family residential building at 350 Frederick Street in Haight Ashbury, owned by Jack Doyle, was constructed in 1907 and has undergone several significant improvements in recent years. Most notably, there is an active permit application (202501067810) from January 2025 for constructing a one-bedroom ADU in the first floor storage area. The property has seen substantial unit upgrades between 2019 and 2021, including kitchen remodels in Units 2 and 3, bathroom renovations to address moisture and mold issues (completed in 2019), and full rewiring of kitchens and bathrooms with new lighting installations. A sewer replacement was completed in 2015, demonstrating attention to critical infrastructure.

The building has undergone regular housing inspections in 1998, 2004, and 2016, with no active violations recorded. While there have been multiple recent 311 calls concerning the property, particularly regarding illegal parking (with several citations issued between December 2024 and January 2025) and some sidewalk-related issues, most of these incidents have been resolved and do not directly impact building safety or habitability. The only recorded fire incident was a CO detector activation due to malfunction, with no injuries reported. The property's maintenance history shows regular upkeep and improvements, with active permits and completed work suggesting ongoing investment in the building's infrastructure and resident amenities.

Risk rating

How 350 Frederick 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
67th percentile

Out of 581 buildings in this neighborhood, 192 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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 77.9%
Moderate concern 13.1%
Severe concern 9.0%
