Initial analysis

1323 47th Avenue is a two-story, four-unit multi-family residential building located in San Francisco's Outer Sunset neighborhood, owned by Sally L. Liu and constructed in 1959. The property has undergone several recent improvements, including a proposed window replacement project filed in August 2023 to install 19 new Milgard windows with improved energy efficiency. Significant historical renovations include the installation of two back windows in 1996, roofing work in 1989, and more substantial improvements in 2013 to comply with a notice of violation, which included adding skylights and creating partition walls to legalize additional bedrooms in two units.

The building has experienced multiple maintenance and safety issues over the past decade, most notably in 2014-2015 when serious concerns were documented regarding termites, electrical problems, and structural issues. A particularly concerning pattern of complaints emerged in 2022, when the building was cited for various violations including inadequate smoke detectors, fire safety issues, and lead paint concerns. There were also reports of significant exterior deterioration, with tenants noting the presence of cardboard in place of windows. A routine inspection in June 2022 revealed multiple building code violations that were addressed by August 2023. Earlier complaints from 2015 documented security concerns with damaged doors, and multiple 311 calls in 2021-2024 have reported issues with waste management and parking violations in the surrounding area. While the property experienced a trash-related fire incident, it was contained with no civilian injuries reported. Recent efforts to address building violations and upgrade windows suggest ongoing maintenance attention, though the property's history shows recurring maintenance challenges and safety compliance issues.

Risk rating

How 1323 47Th 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.
