Initial analysis

The multi-family residential building at 471-473 30th Street in Glen Park is a 2-story, 5-unit apartment building constructed in 1908, currently owned by Eamon Corry. The property has a significant history of compliance issues, particularly regarding seismic safety requirements. While a $125,000 permit for a soft-story retrofit was issued in October 2019, the building remains classified as non-compliant under the mandatory Soft Story Retrofit Program, with active violations from November 2019 still pending resolution as of 2023. The building faced multiple enforcement actions between 2017 and 2019 regarding this issue, including monthly violation monitoring fees and an earthquake warning placard requirement.

The property has also experienced several safety and compliance concerns. In 2009, multiple violations were documented during a routine inspection, including deficiencies related to fire safety (fire extinguisher maintenance, fire escape ladder repair), security requirements (door viewers), and smoke detection systems (central alarm system). More recently, in October 2019, complaints were filed regarding unpermitted construction work involving a deck and spiral staircase, though one of these complaints has since been marked as "not active." The building's maintenance history shows some positive developments, including the issuance of proper permits for security upgrades and window replacements, though these improvements are now several decades old.

Risk rating

How 471-473 30Th 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
