AI summary

The 401-411 Haight Street property is a three-story, multi-family residential building with 11 units, built in 1900 and currently owned by Ko-ri Inc. The building has undergone significant seismic retrofit work, completing its mandatory soft-story retrofit in 2022-2024 under San Francisco's Tier 4 program, which included both residential and commercial components. This work demonstrates compliance with modern safety standards, though there was a notable period of incomplete work from 2018 to 2024 with multiple permit revisions and extensions totaling over $250,000 in renovation costs. The property has maintained active efforts to improve accessibility, including an ADA bathroom remodel and accessible entrance work completed in 2022-2024.

Historical records show several maintenance and compliance issues were addressed between 2006-2016, including multiple building violations that were abated by 2016, related to various safety and maintenance concerns such as fire safety, stair treads, floor repairs, and lead paint hazards. Recent inspections have revealed some ongoing maintenance needs, with a common areas complaint filed in July 2023 currently active. The building's systems have been upgraded in recent years, including a new 400-amp service installation in 2020. A 2022 complaint regarding unauthorized signage was referred to SF Planning enforcement, and there have been multiple recent 311 calls (December 2024) regarding street-level cleanliness issues that appear to be external to the building itself. Fire safety inspections in 2022 and 2023 showed no merit for complaints regarding blocked exits and street numbering, though an extinguisher issue was corrected in 2022.

Risk rating

How 401-411 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.
