Initial analysis

The 993-999 Steiner Street property is a 6-unit, 3-story apartment building constructed in 1900, currently owned by Cheung Wing C & Sioe D, and classified as a Multi-Family Residential building. The property has undergone significant recent improvements, including a complete roof replacement in July 2023 ($47,000) and lightwell stucco wall renovation ($4,000). The building successfully completed its mandatory soft-story retrofit program in 2019-2021, initially facing violations for non-compliance but ultimately addressing seismic safety requirements through a $65,000 retrofit project and additional improvements including new roof drainage systems and electrical grounding.

The building has a history of various maintenance and safety issues spanning several decades, with the most recent concerns primarily involving building systems and infrastructure. Notable historical violations included heating system failures, interior surface repairs needed in 2001, and multiple fire safety-related violations in 2008 (including issues with handrails, fire proofing, combustible storage, and alarm systems) that were all ultimately abated by October 2021. A significant cluster of recent 311 calls from late 2024 has been recorded regarding garbage and debris issues, though these primarily relate to public sanitation and not directly to building conditions. The property was briefly associated with concerns about unauthorized group housing or short-term rental operations in 2020 (described as a "hacker hostel"), but this issue appears to have been resolved and closed by planning authorities.

Risk rating

How 993-999 Steiner 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.

Neighborhood percentile
