HUD HCV Guidebook § 2.3

For the family that requires an accessible unit, a unit in close proximity to medical services, or a particular unit
because of another disability-related reason, the accessible features, location, or other particulars of the unit
may justify a higher rent under the rent reasonableness provisions in 24 CFR § 982.507(b)(1). For such
families, the rent reasonableness determination must9 take those features into account. A PHA must permit a
higher rent that may be necessary as a reasonable accommodation for persons with disabilities in accordance
with Federal civil rights laws.
