Initial analysis

The 6-unit, 2-story multi-family residential building at 4118 24th Street in Noe Valley, owned by Chun Hsia Revocable Lvg Tr, has undergone several significant safety and infrastructure improvements since its construction in 1963. Most recently, in July 2023 and October 2023, the building completed important fire safety upgrades, including an improved fire alarm system installation costing $22,500 and further fire alarm modifications to add low-frequency sounders in sleeping areas and meet modern fire safety standards. The property successfully completed its mandatory soft-story seismic retrofit in 2022 (with costs of $75,000 in 2014 and an additional $10,000 revision), demonstrating compliance with important seismic safety requirements. The building experienced a significant cluster of violations in 2001 related to fire safety, including issues with the alarm system, floor coverings, smoke enclosure door, fire escape ladder, egress obstructions, fire extinguishers, and plumbing/electrical systems, though all were resolved by 2010. A kitchen remodel complaint in 2010 was promptly addressed through proper permitting.

The property's maintenance history shows attention to basic infrastructure needs, including termite repairs (1997), window and door replacement (1998), and kitchen improvements (2010). Recent 311 calls from 2021-2024 primarily relate to street cleaning and graffiti issues in the surrounding area, with the most recent call in October 2023 regarding graffiti. A fire-related incident in 2021 was recorded as a non-fire alarm system activation with no injuries. The building's fire safety systems appear to be properly maintained, with a July 2021 fire complaint regarding alarm systems resulting in correction of the identified condition. The structure has not had any major building code violations since 2010, and recent routine inspections have shown compliance with necessary regulations. The property maintains an active status in housing inspections, with no recent significant violations or complaints affecting resident safety or habitability.

Risk rating

How 4118 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.
