Initial analysis

The property at 441 24th Avenue is a 3-story, 11-unit multi-family residential building constructed in 1925, currently owned by Grinsell Lake Llc. The building has undergone significant maintenance and improvements over the past decade, including a completed soft-story retrofit in 2015 ($70,000) which has brought the building into compliance with seismic safety requirements. Recent and ongoing maintenance includes unit-specific renovations, with the most recent work being a kitchen and bathroom remodel in Unit 9 ($64,000) that is currently permitted as of November 2024. The building has received regular upgrades to maintain safety systems, including a fire alarm upgrade in September 2023 and multiple fire safety improvements through the years, though there have been recurring issues noted with fire extinguishers and alarm systems, as documented in multiple fire complaints dating back to 2007.

Historical records show some significant concerns between 2013-2014 regarding unpermitted work and construction-related issues, including the removal of earthquake retrofit elements and bathroom renovations, though these violations were eventually addressed. The building's boiler system has required multiple permit renewals between 2013-2021, indicating ongoing maintenance needs. More recent concerns have primarily related to unit upgrades and routine maintenance, with no major building-wide violations recorded in recent years. The property has experienced some infrastructure maintenance issues in 2019-2021, including water-related problems with sewer vents, and there have been several parking enforcement calls regarding driveway blocking between 2019-2021. The building's most recent major upgrade was a reroofing project completed in 2020 ($23,500), and the property appears to be generally well-maintained with regular unit upgrades and safety system improvements.

Risk rating

How 441 24Th 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
