Initial analysis

The property at 324-326 Frederick Street is a century-old two-unit residential building located in the Haight Ashbury neighborhood, currently owned by John C. Borcher. The two-story flats/duplex structure, built in 1906, has undergone several significant improvements over the past decade. Most notably, in 2021, extensive kitchen remodels were completed in both units, including the removal of a load-bearing wall between kitchen and dining areas, supported by both building and electrical permits totaling approximately $40,000. The building has received proper maintenance attention with a complete reroofing project completed in 2015 at a cost of $16,800.

The property's plumbing infrastructure has been actively maintained, with documented work including kitchen sink drain replacements in 2014 and attempts to address sewer line and house trap issues in 2017, though those permits ultimately expired. The building has undergone regular routine housing inspections in 2003 and 2008, with no active violations noted. Two 311 calls have been recorded - one in 2016 regarding hazardous materials (resolved) and another in 2020 concerning improper postings (also resolved). Planning records indicate previous proposals for building modifications, including a rear stairway addition and garage space improvements, though these appear to be marked as closed or approved without further action. The property's maintenance and improvement history suggests active management, with particular attention paid to modernizing and maintaining essential systems, though the expired sewer-related permits from 2017 merit noting as potentially indicating incomplete resolution of that specific infrastructure issue.

Risk rating

How 324-326 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
96th percentile

Out of 581 buildings in this neighborhood, 23 are predicted to be safer.

Model explanation

What's driving this score

Permits pulled across all of this owner's buildings over 7 years.

Permit rate, owner's portfolio

Per-building permit rate across the owner's portfolio.

12-Month severity forecast
No violation 84.6%
Moderate concern 11.4%
Severe concern 4.1%
