Initial analysis

The two-story multi-family residential building at 1503-1509 11th Avenue in San Francisco's Inner Sunset neighborhood is a 4-unit apartment structure owned by Cuan Fmly Tr, constructed in 1922. The building's maintenance record shows several significant events, with the most recent major repair occurring in 2011 when staircase repairs and railing upgrades were completed at a cost of $4,400 to meet safety codes. This work was prompted by a housing inspection that identified staircase issues, though these violations were promptly addressed within three days of being filed. The building has undergone routine safety inspections through Housing Inspection Services in 2001, 2002, and 2011, indicating regular oversight of building conditions.

Recent activity around the building from 2022 to 2024 has primarily involved external maintenance and public space concerns, including multiple reports of driveway blocking incidents, pavement defects, and street cleaning needs in the vicinity. There were also some exterior maintenance issues recorded, such as graffiti and illegal postings in 2023, though these cases were resolved. Of note is a single cooking-related fire incident that was contained and caused no civilian injuries, though the date of this occurrence was not specified in the records. The building's last major documented internal improvement was the reroofing work from 1996, which is now considered expired under current permit status. The most recent building-related service request from October 2024 concerns water service, which remains open.

Risk rating

How 1503-1509 11Th Ave'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.
