Initial analysis

The two-story, four-unit multi-family residential building at 1405 48th Avenue in the Outer Sunset, owned by Lee Paul S & Eun Young, was constructed in 1955 and has undergone several significant maintenance updates over the years. Most notably, the building received a complete reroofing in 2021 at a cost of $12,500, following a similar $8,000 reroofing project completed in 2011. A important safety upgrade was performed in 1992 when the fire escape platform, grates, and ladder were restored and regalvanized, demonstrating attention to life safety systems.

The building's history includes two routine housing inspections by Housing Inspection Services, one in 2000 and another in 2002, which revealed multiple fire safety issues including problems with fire extinguisher pressure, fire escape ladders, smoke enclosure door closers, and unauthorized storage. All these violations were abated within reasonable timeframes, with the 2002 inspection occurring just before a complete restoration of the fire escape systems. More recently, in 2019, a violation was issued for combustible materials/storage, though this was promptly abated within a few days. The property has experienced recurring issues with sidewalk parking violations, with seven documented incidents between 2020-2023, including multiple citations issued to offending vehicles. Recent maintenance and service requests have primarily involved street cleaning and garbage-related issues, with the most recent service occurring in September 2024. While the building has had historical fire safety violations, recent years show improved compliance with safety requirements, though the concentration of parking violations in the surrounding area remains notable.

Risk rating

How 1405 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.

Neighborhood percentile

Out of 632 buildings in this neighborhood, 525 are predicted to be safer.
