Initial analysis

The multi-family residential building at 100-108 Carl Street, constructed in 1908, is a 3-story, 6-unit apartment building located in the Parnassus/Ashbury Heights neighborhood, currently owned by Kung Ti Ching - Ot. The property has undergone several significant improvements in recent years, with particular attention to safety systems: in 2021, the building received a fire alarm system upgrade including radio monitoring and low-frequency sounders, and bathroom renovations were completed to address water damage and dry rot issues. The building has a history of maintenance and upgrades, including the replacement of windows, doors, and various plumbing systems, with notable work in 2013 involving electrical renovations, plumbing upgrades including a new main waterline, and the installation of a grease trap and kitchen equipment.

The property has experienced some maintenance challenges over the years, including multiple instances of dry rot repairs in 2013 and 2021, and a sewer pipe replacement in 2018. Historical building violations from 2000-2006 were primarily related to fire safety and security issues, including problems with the central alarm system, handrails, and self-closing doors, though these were all abated by December 2000. More recent issues include concerns about exterior paintwork in 2018 involving lead paint, and some tenant complaints about garbage and debris management in late 2024. The building's commercial space has operated as a restaurant with related ABC Type 41 licensing, and there have been recent fire safety inspections in connection with shared spaces. Recent 311 calls from January 2025 suggest ongoing issues with garbage management in the area, with multiple reports of overflowing city garbage cans being resolved by Recology services.

Risk rating

How 100-108 Carl 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.
