HUD discontinued approving builders in 1995 and amended the Builder Certification process to include certifications for compliance with HUD Guidelines including Affirmative Fair Housing Marketing Plans.
Outstanding instructions to lenders on acquiring and retaining construction plans, specifications, builder warranties, etc., remain in effect.
While the mortgagee is expected to collect and retain certified plans, specifications and other documents from the builder, it is not expected to review or "approve" them. For more information on Affirmative Fair Housing Marketing Plans, see Mortgagee Letter 2001-09.
