Initial analysis

The property at 1450 48th Avenue is a two-story, four-unit multi-family residential building constructed in 1959, currently owned by Ray M & Dionisia Aquino Trust and located in San Francisco's Outer Sunset neighborhood. The building's most significant recent maintenance event was in October 2004, when the front steps were replaced to address rust issues, with a documented cost of $1,500. A cluster of building violations was recorded in June 2001 during a routine housing inspection, primarily relating to safety and security issues including the need for a gas utility shutoff tool, fire extinguisher recharge, and proper door viewers for unit #3; however, all these violations were promptly resolved within one month by July 16, 2001.

The property has experienced recurring issues with parking violations in the immediate vicinity, particularly between 2019 and 2024, with multiple documented cases of driveway blocking and illegal parking. Of particular note, there were ten separate parking enforcement incidents between April 2019 and February 2022, with several citations issued and some cases not validated by responding officers. Recent street maintenance calls include reports of garbage and debris in January 2025, sidewalk parking in March 2024, and hazardous materials (glass) in October 2022, all of which were resolved. The building's fire incident record shows two service calls with no civilian injuries reported, though no specific dates or details are provided for these incidents. While the 2001 violations indicated some initial safety concerns, these were addressed in a timely manner and there have been no documented building violations in recent years.

Risk rating

How 1450 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, 537 are predicted to be safer.
