Initial analysis

The two-unit residential building located at 1221-1223 45th Avenue in San Francisco's Outer Sunset neighborhood is a two-story structure built in 1988, classified as a TIC building with 4 units or less, currently owned by Anthony J. Nakamoto. The building's history shows significant improvements made in recent years, most notably a $5,000 window replacement project in late 2019 involving the installation of twelve new front windows made of fiberglass, fibrex/composite, or aluminum, avoiding vinyl materials at the front facade. A water heater replacement was also conducted in 2015, though this permit has since expired. The property's early history shows the demolition of a previous residential structure in July 1987, followed by the construction of the current building later that same month.

Recent incidents reported through the city's 311 system have primarily involved external issues not directly related to the building's condition or safety. These incidents include parking enforcement matters (a sidewalk parking violation in August 2024), abandoned vehicle concerns (also in November 2021), and minor street maintenance issues such as graffiti on a pole (March 2019) and human or animal waste on the street (August 2019). While these external issues have been resolved, they represent typical urban challenges in the neighborhood rather than direct building management or maintenance concerns. The most significant improvement to the building in recent years was the 2019 window replacement project, which enhanced the building's facade and potentially its energy efficiency.

Risk rating

How 1221-1223 45Th 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.

Neighborhood percentile
67th percentile

Out of 632 buildings in this neighborhood, 209 are predicted to be safer.
