The following additions shall be made:
a) Amend
Section C101.1, R101.1 of the IECC as follows:
Section C101.1, R101.1 Title. These regulations shall be known
as the Energy Conservation Code of the City of Mission, hereinafter
referred to as "this code or the IECC."
b) Amend
by adding a new Section C101.4.2 of the IECC as follows:
C101.4.2 Additions, Alterations, Renovations and Repairs. Additions,
alterations, renovations and repairs to existing buildings, building
systems or portions thereof shall perform to the provisions of this
code as they relate to new construction without requiring the unaltered
portions of the existing building or building system to comply with
this code. Additions, alterations, renovations, or repairs shall not
create an unsafe or hazardous condition or overload existing building
systems. An addition shall be deemed to comply with this code if the
addition alone complies or if the existing building and addition comply
with this code as a single building.
Exception: The following need not comply provided the energy
use of the building is not increased.
1. Storm windows installed over existing fenestration.
2. Glass only replacements in an existing sash and frame.
3. Existing ceiling, wall or floor cavities exposed during construction
provided that these cavities are filled with insulation.
c) Amend
Sections C104.2 and R104.2 of the IECC as follows:
C104.2 and R104.2 Schedule of Permit Fees. The fee for each
building permit shall be as set forth by resolution of the City Council.
When permit fees are required, a plan review fee shall be paid at
the time of submitting the submittal documents for plan review. The
plan review fees specified in this Subsection are separate fees from
the permit fees specified in Sections C107.2 or R107.2 and are in
addition to the permit fees. When submittal documents are incomplete
or changed so as to require additional plan review or when the project
involves deferred or amended submittal items as defined in Section
C103.4 or R103.4, an additional plan review fee may be charged.
Applications for which no permit is issued within one hundred
eighty (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 Code Official.
The Building Code Official may extend the time for action by the applicant
for a period not exceeding one hundred eighty (180) days on written
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.
d) Amend
by adding new Sections C110, R110 of the IECC as follows:
C110, R110 Violation Penalties. Violations of any provision of this code shall be an unlawful act. Each separate day or any portion thereof, during which any violation of this code occurs or continues, shall also be deemed to constitute a separate offense, and shall be punishable as provided Municipal Code Section
100.100.
C110.1, R110.1 Prosecution of violation. Any person failing
to comply with a notice of violation or order shall be deemed guilty
of an unlawful act. If the notice of violation is not complied with,
the Building Code Official may request the legal counsel of the jurisdiction
to institute the appropriate proceeding at law or in equity to restrain,
correct or abate such violation, or to require the removal or termination
of the occupancy of the building or structure in violation of the
provisions of this code or of the order or direction made pursuant
thereto.
