Seven percent (7%) of all residential units within the development must comply with the Level 5, "All-Inclusive" usability criteria as set forth in the Arkansas Department of Human Services' "Arkansas Usability Standards in Housing: Guidance Manual for Constructing Inclusive Functional Dwellings." (AUSH). The AUSH is available on the internet at: www.studioaid.org. Under "Design" click on "standards."

B. Each unit that is required to meet the Level 5, "All-Inclusive" usability criteria set forth in the AUSH must have at least one bathroom with an "accessible roll-in" shower facility with minimum dimensions of 60" x 34" or 42" x 42" if a corner shower facility.

C. All ground level residential units in any building and all residential units with elevator access in any building in the development must comply with the Level 1, "Visitable" usability criteria as set forth in the AUSH.

It is applicant's responsibility to engage a HERS rater and, if funded, to work closely with the HERS rater to ensure that the development is built as represented in the application.

Applicant must submit a signed, certification from the HERS rater stating that the newly constructed units and buildings will be ENERGY STAR® qualified and meet the minimum HERS Index Score of 70 or 78, as applicable.

A signed, written certification from the HERS rater, certifying that the newly constructed units and buildings are ENERGY STAR® qualified and that the HERS Index score as represented in the application has been met must be submitted to ADFA before ADFA will issue any IRS Form 8609 for the development.

VII. Rehabilitation developments:

If structural constraints prohibit adherence to ADFA's "Multi-Family Housing Minimum Design Standards", applicant may seek a waiver from ADFA of the standard concerned. Such waiver request must be in writing and include the following:

A. Certification by the design architect or licensed engineer that the standard concerned cannot be met due to structural constraints;

B. Certification by the design architect or licensed engineer that no alternative design can be undertaken to achieve the benefit of the required standard due to structural constraints; and

C. If applicable, statement by applicant that it will implement any alternative identified by the design architect or licensed engineer.

ADFA reserves the right to amend these Minimum Design Standards as necessary to prudently administer ADFA-administered funds or to comply with state or federal law. ADFA reserves the right to adopt rules ancillary to these Minimum Design Standards as necessary to prudently administer ADFA-administered funds. ADFA reserves the right to make any and all necessary technical changes to these Minimum Design Standards as circumstances may warrant.
