Initial analysis

The property at 1401 24th Avenue is a two-story, 8-unit multi-family residential building constructed in 1959, currently owned by Bill T Vourthis Separate Pr. The building has undergone significant improvements over recent years, with the most recent major upgrade being the completion of a new fire alarm system installation in October 2023 that includes low-frequency horns throughout the building. Other notable recent improvements include a bathroom cosmetic remodel (#7) in April 2022 ($20,000) and a unit 2 renovation in 2021 ($26,000) that included kitchen and bathroom updates. The building has been proactive in addressing safety requirements, completing a mandatory soft-story retrofit in 2016 at a cost of $60,000, and upgrading the fire alarm system to comply with new ordinances in 2019.

The building's maintenance history shows regular upkeep, including reroofing work in 2019 ($28,000) and electrical system upgrades to 400-amp service with individual meters. Historical data reveals several violations primarily related to fire safety issues, all of which were abated between 2000-2011, including concerns with fire proofing materials, fire escape ladders, and fire extinguisher maintenance. A complaint regarding unpermitted plumbing and electrical work was filed in June 2021 but was promptly addressed by July 2021. The property has maintained compliance with building codes, as evidenced by obtaining a Certificate of Final Completion (CFC) for its tier 3 soft-story retrofit status, though it has undergone periodic routine safety inspections over the years.

Risk rating

How 1401 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
