Initial analysis

The property at 3770 24th Street is a 4-unit multi-family residential building in Noe Valley, built in 1900 and currently owned by Erpen Family Investment Co. The building has undergone several significant improvements, including window and door replacements in 2007 and 2013, with both projects installing energy-efficient vinyl windows and doors. However, the building has experienced persistent maintenance issues in recent years, with multiple active violations and complaints. As of 2024, several active concerns remain, including ventilation system repairs, weatherproofing issues, and interior maintenance problems. Notable recent complaints include a non-functioning intercom system (May 2024), a broken kitchen stove (April 2024), and ongoing concerns about heating and water leaks from 2022-2023.

The building has a history of various violations that have required landlord attention, including multiple fire-related issues in 2023-2024, such as a sleeping area requirement violation and hazardous materials concerns. A significant complaint regarding possible soft-story construction was documented in March 2023, though this appears to have been resolved by October 2023. The property has also faced recurring maintenance challenges, including water intrusion and heating system problems documented in early 2023. The building's exterior and common areas have generated multiple 311 calls in 2023-2024 for general cleaning, including reports of garbage and debris, though these issues are primarily related to building surroundings rather than the structure itself.

Risk rating

How 3770 24Th 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.
