FEMA checks four building blocks in order: applicant, facility, work and cost. If any one can’t be shown, FEMA can’t fund it. Simplified procedures let small projects use summaries and self-certification, and FEMA can review a sample of large document sets instead of every page.
Summary documentation for each building block, with full source records kept on file.
Self-certifying doesn’t mean you can discard backup. A later audit or closeout review will ask for the source records behind every certification.
