Add new subsection: “All applications for building permits shall be accompanied by a permit closeout escrow in amounts established by the Board of Trustees by resolution from time to time. The escrow shall be held by the Village for the duration of the work under the permit and returned to the permittee or property owner of record only after the completion and final inspection and approval of all work under the permit within the term of the permit or any lawful extension thereof. If the completion, final inspection and approval of the work does not occur prior to the expiration of the permit or any lawful extension thereof, the Village must send notice to the property owner of record and the permittee stating that the escrow will be forfeited to the Village unless the owner of record or permittee, within 30 days after the notice date, takes corrective action by: (i) completing the work and obtaining final inspection and approval; (ii) obtaining a lawful extension of the permit term; or (iii) otherwise arranging to complete the work in a manner acceptable to the Village Manager. If the property owner of record or permittee fails to take such corrective action within 30 days, the escrow will be retained by the Village to cover the costs and expenses associated with the administration of any final inspections and approvals of the work.”

Delete section and substitute: “Within 10 working days following receipt of a request by the holder of a permit, the Building Commissioner may review and determine whether the request meets the requirements to issue a temporary certificate of occupancy of a portion of the work covered under the building permit, before the completion of the entire work covered by the permit, provided that such temporary certificate of occupancy may be issued only where such portion or portions shall be occupied safely prior to full completion of the structure without endangering life or public welfare. Such temporary certificates of occupancy shall be issued for a period of no more than six months, One and Two Family Dwellings, Article III - 3 unless an extension is granted by the Building Commissioner. To obtain a temporary certificate of occupancy, the holder of a building permit must:
(a)   Sign a written agreement with the Village stipulating remaining work to be done and/or deficiencies which must be corrected. Such agreement may contain additional stipulations as may from time to time be deemed in the best interest of the Village by the Building Commissioner. Such agreement shall be co-signed by the owner, contract purchaser and/or the tenant; and
(b)   Post an additional cash deposit or irrevocable letter of credit acceptable to the Village Manager, in an amount equivalent to (1.) 110 percent of the estimated cost of completing and/or remedying all items stipulated to in the agreement (which amount shall be not less than an amount established by the Board of Trustees by resolution from time to time) plus (2.) a temporary certificate of occupancy fee in amounts established by the Board of Trustees by resolution from time to time.
Failure by the holder of a temporary certificate of occupancy to obtain a final certificate of occupancy by the date established by the Building Commissioner shall result in automatic forfeiture of the related cash deposit or irrevocable letter of credit. The Building Commissioner may, but shall not be obligated to, use such forfeited funds to complete the work indicated on the inspection report attached to the temporary certificate of occupancy, which was issued for the premises. Such forfeiture shall not impair the right of the Village to enforce any and all remedies available to it by reason of any violation, including the right to recover a fine or penalty or seek injunctive relief. In the event that the Building Commissioner uses such forfeited funds, he shall assess and deduct an administrative fee equal to 10 percent of the amount of forfeited funds used. Any balance remaining in the cash deposit or irrevocable letter of credit not required to complete the work shall be refunded to the depositor upon issuance of a final certificate of occupancy.”
