Initial analysis

The two-unit residential building at 264-266 San Carlos Street in San Francisco's Inner Mission district is a two-story structure built in 1912, currently owned by the Do Yeany Louie Trust. The building's maintenance history includes a significant window upgrade project completed in 2002, where 20 replacement windows were installed at a cost of $5,600. More recently, in 2018, a street space permit was issued, though the associated cost was listed as $0.

A notable incident occurred in April 2023 when building management was reported to be undertaking unauthorized construction work while also allegedly blocking parking spaces and enforcing towing of vehicles in violation of driveway access. This complaint was addressed within one day of being filed. The property and surrounding area have experienced recurring issues with public space maintenance, particularly during mid-2023, when multiple reports were filed regarding sidewalk cleaning needs, including loose garbage issues on several occasions. Infrastructure concerns were documented in July 2023, including reports of sidewalk collapse and curb defects, though these were subsequently resolved through the appropriate city channels. The most recent activity in early 2024 continues to show attention to street maintenance, with two general cleaning cases being resolved for loose garbage issues.

Risk rating

How 264-266 San Carlos 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.
