(4) Add IBC § 105.8 as follows:
No building permits shall be issued to any person or company who has fees outstanding, or who has outstanding, unresolved violations of this Code or any other laws or ordinances of the City. The Building Official may waive this restriction for just cause.

(6) Delete IBC § 109.3 and replace with the following.
The building valuation will be derived from the most current Building Valuation Data Schedule published in the Building Safety Journal.
Add a line valuing detached garages and accessory structures at $15 per square foot.
Add a line valuing open decks at $10 per square foot.
Add a line valuing below-ground swimming pools at $25 per square foot and above-ground swimming pools at $10 per square foot.
Add a line valuing screened porches at $15 per square foot.

A separate permit for a foundation shall be valued at 20% of full building value, and the remaining 80% of value shall be assigned to the permit for the remainder of the building.
The permit for a shell building shall be valued as a warehouse (S-1), and permits for tenant finishes shall be valued at the difference between the warehouse value and the value assigned for the specific finished use.
Remodels are valued at one-eighth (0.125) of full value. Valuations for the aforementioned list of specific projects may be adjusted from time to time by Resolution of the City Council.
(7) Amend IBC § 109.4 by adding the following to the text for the fee for starting work before permit issuance:
The fee for starting work before acquiring the permit is 100 percent of the usual permit fee in addition to the required permit fee, with a $750 limit. This section is not to be interpreted as requiring this fee the first time the person neglects to acquire the permit, but to control the practice of failing to acquire permits before construction commences.
(8) Add IBC § 109.5.1 by adding provisions as follows.
Plan Review Fees. When submittal documents are required, a plan review fee shall be paid at the time of submitting the submittal documents for plan review, unless the Building Official delays requiring payment until permit issuance. The plan review fee shall be 65% of the building permit fee. This plan review fee is separate from the permit fee, and is in addition to the permit fee.
When submittal documents are incomplete or changed so as to require additional plan review or when the project involves deferred submittal items, an additional plan review fee shall be charged at the applicable rate. This subsection does not apply to IBC Group U Occupancies, Group R-3 (one & two family) Occupancies, unless the Building Official determines that there are unusual or unique features requiring specialized plan review.
Expiration of Plan Review. Applications for which no permit is issued within 180 days following the date of application shall expire by limitation, and plans and other data submitted for review may thereafter be returned to the applicant or destroyed by the Building Official. The Building Official may extend the time for action by the applicant for a period not exceeding 180 days on request by the applicant showing that circumstances beyond the control of the applicant have prevented action from being taken. No application shall be extended more than once. In order to renew action on an application after expiration, the applicant shall resubmit plans and pay a new plan review fee.
(9) Amend IBC § 110.3.9 by adding the following text:
Fences: To be made after holes have been dug for all corner posts, and for additional posts as deemed necessary by the Building Inspector; and a final inspection upon completion of work.
(10) Amend IBC § 110.4 by adding the following paragraph:
Where the work requiring a building permit includes one or more prefabricated assemblies, the certificate of approval required by IBC 1703.6 may be accepted in lieu of the written approvals required by IBC §§ 110.3.1 through 110.3.7, and the frame and lath and/or wallboard inspection required by IBC 110.3.5 where the use of prefabricated assemblies renders the obtaining of approvals or inspection impractical. All certificates of approval for this purpose and as required by IBC § 1703.6 of this Code shall be made by the International Code Council, Underwriter's Laboratories, Inc., or any other approved independent inspection agency qualified to make the certification. Also all prefabricated assemblies must be certified to comply with regulations of the State Building Code.
(11) Add IBC § 110.7 regarding reinspections as follows:
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 inspection or reinspection.
Reinspection fees may be assessed when the inspection record card is not posted or otherwise available on the work site, the approved plans are not readily available to the inspector, for failure to provide access at the scheduled time for which inspection is requested, or for deviating from plans, which then requires the approval of the Building Official.
To obtain a reinspection, the applicant shall request that it be scheduled in the normal manner in which inspections are scheduled, and pay the reinspection fee in accordance with this ordinance.
In instances where reinspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid. Only the work necessary to correct what has been noted in the inspection or reinspection report is to be done until all reinspection fees are paid and reinspections satisfactorily completed.
(12) Add IBC § 111.2.1 as follows:
Prior to issuance of a certificate of occupancy for new buildings, structures, and any other construction as determined by the Community Development Department, the permit applicant's land surveyor shall provide a certified as-built grading plan to the City showing the as-built elevations of critical locations on the site as shown on the grading plan (including but not limited to the rear corners, the mid-point of the side yard lines, the front lot corners where the storm water flows from the rear yard to the front yard, overflow locations, and along the proposed drainageways and easements), sanitary sewer manholes, and all storm water management facilities (including but not limited to detention areas, intakes, structures, sub-drain cleanouts, and flared end sections) are in compliance with the approved grading plan.
