Multiunit Residential Building Inspections. According to state law enacted in 2005, any person applying for a building permit to construct a building containing more than two attached dwelling units must submit a building enclosure design document to the appropriate building department before beginning construction or rehabilitative construction. Any building enclosure design documents pertaining to waterproofing, weatherproofing, or protection from water or moisture intrusion must be stamped by the architect or engineer. During the construction or rehabilitative construction process, the building enclosure must be inspected by a qualified inspector, who must be the architect, engineer of record, or another person with substantial and verifiable training and experience in building enclosure design and construction. The inspection must include, at a minimum, water penetration resistance testing, and an independent periodic review of the building enclosure during the course of construction to determine whether construction is in compliance with the building enclosure design document. The inspector must prepare a signed inspection certification letter, which is required before the building department may issue a certificate of occupancy.

Conveyances of Multiunit Residential Buildings. Before the conveyance of any condominium unit occupied for residential use in a multiunit residential building, the owner must prove that the inspections described in the above paragraph have occurred, or conduct their own inspection of the building enclosure of the building in which the unit is located, including intrusive testing such as the removal of siding or other building enclosure materials necessary to ascertain how the building enclosure was constructed, and to evaluate the present condition of the building enclosure. This inspection may result in recommendations for repairs to the building enclosure necessary to repair a design or construction defect in the building, or to repair damage to the building enclosure caused by such a defect. 

Exceptions. These restrictions do not apply to a building which is a hotel or motel, dormitory, care facility, floating home, or a structure in which the dwelling units are held under one ownership and subject to a recorded irrevocable sale prohibition covenant. It does not apply to a building containing attached dwelling units which are all located on a single platted lot.

A building with 12 or fewer units that is no more than two stories is exempt from requirements applicable to multiunit residential buildings to:

• submit a building enclosure design document to the building authority before obtaining a building permit;
• obtain a building enclosure inspection by a qualified building inspector during construction or rehabilitative construction; and
• obtain a building enclosure inspection by a qualified building inspector before conveyance of a condominium unit.
