Fannie Mae Multifamily Guide · Section 505

Fannie Mae seismic requirements for multifamily loans.

What the Multifamily Guide requires, in plain terms — and how we deliver a report that matches it.

The requirement

A Level 1 Seismic Risk Assessment is required for properties with a Structural Risk Factor (Form 4099.C), dated within 12 months before the Commitment Date, reporting SEL and SUL at 10% in 50 years, and meeting ASTM E2026 and E2557.

When is an SRA required?

Fannie Mae screens the site first. If the USGS peak ground acceleration is 0.15g or more (10% in 50 years), the lender completes Form 4099.C. A Level 1 SRA is required when the form identifies a Structural Risk Factor.

What the report must contain

  • Level 1 scope, including a site visit
  • SEL (Scenario Expected Loss) and SUL (Scenario Upper Loss) at the 10% in 50-year level
  • Preparation in accordance with ASTM E2026 and ASTM E2557

How old can the report be?

The SRA must be dated within 12 months before the Commitment Date. A report prepared for an earlier financing will usually need to be updated or re-issued.

What happens after the results?

Fannie Mae accepts an SEL of 20% or less on every building that also meets the ASTM E2026 building stability requirements. Above 20%, or with a stability issue, your lender must contact Fannie Mae Multifamily Insurance to agree mitigants. Above 40% on any building, the loan cannot be delivered.
