Initial analysis

The 3-unit, 3-story multi-family residential building at 1224 11th Avenue in the Inner Sunset, built in 1904 and currently owned by the Quan/yong Family Trust, has a notable history of maintenance and compliance issues. Most recently, in June 2023, repairs were completed on front steps and exterior staircases, following previous work in 2019 to address deck repairs and shed removal. A significant renovation occurred in late 2015, which involved adding a bedroom, office, media room, bathroom, and laundry facilities on the first floor, though this work generated multiple compliance concerns. Between 2015-2019, the property faced several building code violations, including issues with deck repairs, plumbing permits, and fire safety equipment, all of which were addressed by October 2019. Multiple 311 calls regarding driveway blocking were logged between 2021-2024, suggesting ongoing parking enforcement issues in the vicinity. The building's maintenance record includes earlier work such as reroofing in 1997 and various improvements over the years, though some past issues remain notable, including a 2015 complaint about roof drainage problems affecting the neighbor's property and a 2016 complaint regarding unpermitted work that raised concerns about neighboring foundation integrity. Recent building permits indicate ongoing maintenance attention by the current ownership, with particular focus on compliance with safety requirements and structural integrity.

Risk rating

How 1224 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.
