Initial analysis

The 6-unit, 2-story multi-family residential building at 1252 48th Avenue in the Outer Sunset, owned by the Nunez Family Trust Of 2017, has a documented history since its construction in 1963, with several significant events impacting resident safety and comfort. Most notably, the building has undergone recent fire safety system upgrades, with a major fire alarm system modification completed in August 2023 and a subsequent fire alarm system upgrade completed in December 2023, which included the installation of low-frequency sounders in sleeping areas to meet current code requirements. The building experienced two significant fire incidents in 1988-1989, requiring repairs to units 5 and 6, though no recent fire-related incidents have been reported. The property has maintained regular infrastructure improvements, including multiple roofing projects, with the most recent reroofing work permitted in February 2018 at a cost of approximately $16,400.

The building's maintenance record shows attention to building systems, though there have been recurring issues with the fire alarm system, evidenced by multiple false alarms and system malfunctions recorded between 2016 and 2017, and a fire safety violation in 2002 regarding fire extinguisher maintenance in public hallways (which was promptly abated). The property has experienced occasional sewer issues, with reports of backups in 2016 and 2019, and there have been multiple complaints about driveway blocking incidents in 2018. A neighborhood complaint regarding unsafe construction practices was filed in April 2023, though this was subsequently marked as not active. The building's recent history suggests active management of safety systems, particularly fire safety, with significant investment in system upgrades to meet current code requirements, though some legacy issues related to fire alarm performance and parking enforcement have persisted in the building's history.

Risk rating

How 1252 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
33th percentile

Out of 632 buildings in this neighborhood, 423 are predicted to be safer.

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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

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

12-Month severity forecast
No violation 53.4%
Moderate concern 18.0%
Severe concern 28.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
