HUD HCV Guidebook § 2.5

If use of the SAFMR has been designated for a metropolitan area or a PHA has voluntarily opted in to using
SAFMRs, the SAFMRs apply to all tenant-based vouchers, including special housing types, with the exception
of manufactured home space rentals under 24 CFR 982.622 through 982.624. Manufactured home space
rentals are exempt from SAFMRs, and payment standards for manufactured home space rentals continue to
be based on metropolitan area FMRs in accordance with 24 CFR 888.113(g).
All other special housing types are subject to the SAFMRs. For example, under the Single Room Occupancy
(SRO) special housing type, the payment standard is 75 percent of the 0-bedroom payment standard amount
on the PHA payment standard schedule. If the PHA revised the payment standard schedule because of the
applicability of SAFMRs, the payment standard for SRO units would likewise be revised to reflect 75 percent of
the applicable 0-bedroom payment standard amount.
Revisions to the payment standard as a result of the implementation of SAFMRs also apply to the voucher
homeownership program at 24 CFR 982.625 through 982.642. The PHA must use the same payment
standard schedule and payment standard amounts for the homeownership option as for the rental voucher
program.27 The same protections that the PHA may employ for families under HAP when the payment
standard decreases would apply to families assisted under the voucher homeownership option. Furthermore,
the payment standard for a voucher homeownership family is always the greater of the payment standard
used at the commencement of homeownership assistance for occupancy of the home or current payment
standard in effect at the most recent regular reexamination.28
