Initial analysis

The five-unit multi-family residential building at 1369 48th Avenue in the Outer Sunset, owned by Guido & Pierina Giosso Family, was constructed in 1970 and currently stands two stories tall. The property has undergone several significant maintenance activities over the years, including recent reroofing work completed in 2019 at a cost of $9,500. The building faced a cluster of safety and maintenance violations in 2002-2004, which were all abated by November 2004, involving issues with fire safety equipment, security features, and building maintenance. A notable complaint from 2012 reported problems with frontdoor locks, weatherproofing, and potential mold issues, though these were marked as resolved within one month. More recently, there is an active complaint from May 2020 regarding noncompliance with COVID-19 guidelines and lack of proper construction permits.

The property has experienced recurring issues with parking violations and sidewalk obstruction, with several citations issued between 2018-2023, as well as concerns about noise and general cleaning in the surrounding area. A 1987 permit application to legalize building modifications and address inspection report requirements was cancelled, and there were historical repairs to the rear wood stairway in 2004. Routine inspections have been conducted over the years, with the most recent significant maintenance work focusing on the roof structure. The building's maintenance history shows periodic attention to major systems, though the pattern of violations and complaints suggests ongoing challenges with building upkeep and compliance with safety regulations, particularly during the early 2000s.

Risk rating

How 1369 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.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 10.0%
Moderate concern 11.5%
Severe concern 78.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
