Initial analysis

The 6-unit, 2-story multi-family residential building at 267 27th Avenue in Sea Cliff, built in 1962, has undergone several significant structural and safety improvements over the years, including a completed soft-story retrofit in 2016 costing $90,000 that involved reinforcing the ground floor with ordinary steel moment frames and shear walls. Most recently, the building has faced multiple concerning issues in 2023-2024, particularly regarding health and safety compliance. These include a fire escape repair in August 2023 ($200) and a dryer vent exhaust duct rerouting in May 2023 ($1,800) to meet safety requirements. A tenant complaint filed in October 2024 highlighted unresolved mold issues in Unit 2, despite prior attempts to address mold and moisture problems through various inspections and repairs. The building has a documented history of moisture and mold-related complaints dating back to 1995, including significant incidents in 2009 and 2023. Additionally, the property has experienced several fire safety-related issues, including multiple fire extinguisher violations and combustible storage concerns in 2000, though these were resolved by January 2001. While the building underwent exterior improvements such as vinyl siding installation (1998) and reroofing (1990), recent complaints indicate ongoing maintenance and safety compliance challenges that have required intervention from housing inspectors and public health services.

Risk rating

How 267 27Th Ave'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
