Valuation is figured by totaling square footage according to type of building or value of project. The amounts used to determine the valuation shall be set by the Building Official as determined necessary but not to exceed more than once in 12 month period typically beginning in January/February of each year. No building permits shall be issued to any person who has fees outstanding as required by this code or any other laws or ordinances of the City.
B. The determination of value or valuation under any of the provisions of the building code shall be made by the building official. The valuation to be used in computing the permit and plan-check fees shall be the total value of all construction work for which the permit is issued, as well as all finish work, painting, roofing, electrical, plumbing, heating, air conditioning, elevators, fire extinguishing systems and any other permanent work or permanent equipment. A fee for each building permit shall be paid to the building official in the amount set forth in the Schedule of Fees as adopted by the City Council.
C. If a permit is issued for a specific amount of work and, upon inspection, it is determined that more work was performed than was authorized by the permit, the permittee shall amend the permit or obtain another permit to include all additional work and shall pay a new base fee and any unit fees as described in paragraph A above.
D. Permits and Fees for mechanical, plumbing, and electrical work shall meet the requirements of Ordinances 156, 157, and/or 158 respectively.
2. Additional permit fees are as follows:
A. Plan Check Fees: Plan Check Fees shall be in the amount set forth in the Schedule of Fees as adopted by the City Council.
B. Sidewalks and Approaches: Sidewalks and approaches shall be constructed with all new buildings. All approaches must be minimum 6 inches thick concrete from street to property line. Fees for sidewalks and approaches shall be in the amount set forth in the Schedule of Fees as adopted by the City Council.
C. Foundations: The fee for a permit to construct only a foundation shall be 150% of the fee in the amount set forth in the Schedule of Fees as adopted by the City Council. For purposes of this determination, the valuation of the foundation shall be considered to be ten percent (10%) of the total building valuation.
D. Accessibility Review Fee. A fee in the amount set forth in the Schedule of Fees as adopted by the City Council shall be charged for the review of plans in accordance with Sec 661-16.303 of the Iowa Administrative Code and Chapter 11 of the IBC for handicap accessibility provisions. The review fee shall not be required for construction for and associated with one and two family dwellings and for projects with an assessed value of construction of less than $2,000.00.
E. Thermal Efficiency Standards. In addition to other fees required in this section, a fee in the amount set forth in the Schedule of Fees as adopted by the City Council shall be paid to the Building Official for the review of plans and inspection of construction for compliance with the thermal efficiency standards of the Iowa State Building Code.
F. Double Fee. Except in emergency situations, as determined by the Building Official, where work for which a building permit is required by this code is started or proceeded with by any person prior to obtaining a required permit, the fees in the amount set forth in the Schedule of Fees as adopted by the City Council shall be doubled. The payment of such double fee shall not relieve any person from fully complying with the requirements of this code in the execution of the work or from any other penalties prescribed herein. No additional permits of any type shall be issued to any person who owes the City the double fee described in this subsection. However, no double fee shall be imposed upon any person who starts without a permit if:
The work is started on a Saturday, Sunday, or holiday, or during any other day when the Building Department is not normally open for business, and the person secures the proper permit on the next Building Department working day.
G. Refunds. If, within 30 days of the date of issuance, the holder of a building permit decides not to commence the work described in said permit, said person may, upon application to the Building Official, be refunded that portion of the permit fee which is in excess of the permit refund fee in as set forth in the Schedule of Fees as adopted by the City Council.
H. Fees for Permit Renewals as stated in Section 155.07 shall be based on the percentage of valuation of remaining work to be performed provided the plans are not changed. If the plans are changed enough to warrant a review then the permit fee shall be ½ the cost of the original fee plus any fees as set forth in subsection J of this code section.
* Or the hourly cost to the jurisdiction, whichever is greater. This cost shall include supervision, overhead, hourly wages, and fringe benefits of the employees involved.
I. Reinspections. A reinspection fee may be assessed for each inspection or reinspection when such portion of work for which inspection is called is not complete or when corrections called for are not made. This section is not to be interpreted as requiring reinspection fees the first time a job is rejected for failure to comply with the requirements of this code, but as controlling the practice of calling for inspections before the job is ready for such inspection or reinspection. Reinspection fees may be assessed when the approved plans are not readily available to the inspector, for failure to provide access on the date for which inspection is requested, or for deviating from plans requiring the approval of the building official. To obtain a reinspection, the applicant shall pay the reinspection fee as set forth in the Schedule of Fees as adopted by the City Council. In instances where reinspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid.
J. Other Inspections and Fees: See the schedule of fees as adopted by City Council.
Persons performing work for the Federal Government, the State, the county or city may obtain permits for such work without paying the permit fees described herein; provided, however, that nothing in this section shall be construed to exempt payment of permit fees by persons performing work under the direction of the City in connection with the abatement of any public law.
An expired permit may not be reissued without a permit fee except by resolution of the City Council.
