AI summary

The 413-427 Haight Street property is a 3-story, 8-unit multi-family residential building constructed in 1900, currently owned by Ko-ri Inc. The building has undergone several significant improvements and faced multiple compliance issues over the years. Most notably, a mandatory soft-story retrofit was completed in 2023, following previous incomplete attempts in 2018 and 2022. The building has also received substantial electrical upgrades, with a permit issued in December 2023 for replacing 12 subpanels. Recent kitchen cabinet replacements in 2022 were performed under proper permits and included corresponding plumbing and electrical work.

The property has a history of various building code violations and complaints, particularly regarding unauthorized conversions between commercial and residential uses. Several complaints between 2002 and 2016 documented concerns about unauthorized residential use of commercial spaces, though these violations are now inactive. In August 2023, the building received a violation related to sprinkler system service that has since been rescinded. The building's maintenance record shows attention to both fire safety and earthquake retrofitting requirements, with recent soft-story work achieving Tier 4 compliance. Current 311 calls from late 2024 primarily relate to street-level maintenance issues such as graffiti and debris removal, rather than building-specific problems.

Risk rating

How 413-427 Haight 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.
