Initial analysis

This two-unit multi-family residential building, located at 343-345 Carl Street in the Parnassus/Ashbury Heights neighborhood, was constructed in 1922 and is currently owned by Yu Clement C & Lo Roxana W. The property has undergone several significant maintenance and improvement projects, including a window replacement in 2017 (cost: $5,000) and a complete reroofing in 2004 (cost: $5,000), which was notably prompted by a series of roof-related safety issues. In June 2004, multiple complaints were filed regarding falling terra cotta tiles from the roof, resulting in temporary violations that were subsequently abated within approximately one week following the roofing work. An earlier safety concern was documented in 1996 regarding issues with back stairs including rotted support posts, loose treads, and railing problems, though these were also resolved promptly.

Recent activity at the property has primarily consisted of routine urban maintenance issues, none of which appear to directly impact the building's condition or safety. These include several parking enforcement cases for vehicles blocking driveways (most recently in August 2023) and multiple reports of sidewalk cleaning needs between 2018-2021. A 2019 planning record noted potential unauthorized window replacements, though it was marked as "Closed - Abated." The building's maintenance history indicates responsive management to safety concerns, particularly regarding major systems like roofing and windows, though the cluster of complaints in 2004 regarding roof tiles suggests there was a period of some structural maintenance challenges that were subsequently addressed.

Risk rating

How 343-345 Carl 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 526 buildings in this neighborhood, 116 are predicted to be safer.
