Initial analysis

The property at 1381 48th Avenue in San Francisco's Outer Sunset neighborhood is a two-story, four-unit multi-family residential building owned by Sammy & Eleanor S L Louie R, constructed in 1974. The building's maintenance record shows several significant improvements over the past decade, including a $20,000 reroofing project completed in 2017, a $5,000 foundation repair completed in 2016, and the replacement of five vinyl windows and siding work in 2013 costing $6,000. These renovations suggest regular maintenance and upkeep of the property by the owners.

The building's history includes one notable incident related to fire safety in 2002, when a violation was recorded regarding a smoke enclosure door closer at the garbage room door. However, this issue was promptly addressed and abated within two months. More recent records from 2021 show two 311 calls related to municipal services and street maintenance outside the building, specifically regarding a maintenance repair complaint and a pavement defect, though these were not directly related to the building's condition or management. The property's documented history indicates generally responsible maintenance practices, with all identified issues being resolved promptly and no recurring violations or safety concerns noted in recent years.

Risk rating

How 1381 48Th 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.
