Section 105 of the IBC adopted in section 22-131 is amended by adding the following:

(a) All exterior work required for construction of new additions, garages (attached and detached), patio covers, decks, swimming pools, gazebos, sun rooms, porches, and carports, roofing, required to be permitted by the city of Aurora building codes, commenced by a homeowner acting as contractor shall be completed within one year of the issuance of the permit for such work. Failure to complete all exterior work within the one-year period shall void the permit, and require reapplication for a six-month permit extension for the work, and the fee therefor shall be the full amount required for the original work. A homeowner acting as contractor may apply for one and only one such extension for one additional six-month extension within which the work must be completed. Failure to acquire such an extension or failure to complete such exterior work under such an extension shall constitute a violation of this section as described in subsection (b) below.

(b) It shall be unlawful for a homeowner acting as contractor to undertake, maintain, or continue construction without a lawfully issued, current building permit unless such structure is exempt from a building permit requirement.

(c) This section shall apply to current building permits issued prior to the effective date of this section. The one-year period shall commence upon the effective date of this section.
