Initial analysis

The three-unit apartment building at 525-527 Hugo Street in San Francisco's Inner Sunset neighborhood is a three-story multi-family residential structure built in 1907, currently owned by the Patricia Fripp Trust 2011. The building has undergone several maintenance and safety-related improvements over the past two decades, with the most recent significant work being a sewer lateral replacement completed in April 2019 and a roofing project completed in 2015 costing nearly $10,000. Notable structural maintenance includes dry rot repairs performed in 2001, deck repairs in 2015, and historical improvements such as mineral fiber siding installation in 1992 and electrical upgrades in 2004. A concerning incident occurred in August 2015 when there was a complaint about unpermitted work related to balcony replacement/removal, though this complaint is currently listed as not active.

The building's safety record shows no significant fire incidents, though there was one recorded carbon monoxide incident with no civilian injuries. Recent external concerns include two defaced parking signs in 2020 and 2021, and a noise-related complaint in April 2024, though these are not directly related to building safety or maintenance. The property has maintained active compliance with necessary permits and inspections, with a completed street space permit issued in 2005, though the status of the 1997 renewal permit is marked as complete without further details. While the building has required various repairs and improvements over the years, particularly addressing dry rot issues in 2001, there are no current active complaints or violations on record that would significantly impact resident safety or experience.

Risk rating

How 525-527 Hugo St'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.
