these provisions. Unless the permit holder applies in signed writing
for segregated investment of its escrow deposit at the time of permit

general revenue purposes at any time. If the permit holder applies
by timely signed writing for segregated investment of its escrow deposit,
the City shall segregate such funds and invest them in the same manner
as allowed for municipal funds, to the extent practicable given the
amount of the escrow; however, no return is assured and the City shall

derived from such investment in the event of return of such escrow
deposit. In the event of a forfeiture of an escrow deposit, any income
from segregated investment shall also be forfeited.
42.

report the findings to the Code Official having jurisdiction.
43.
111.1 Use and occupancy for new buildings. Any
building or structure hereafter constructed shall not be used or occupied
in whole or in part until the certificate of occupancy shall have
been issued by the Code Official. The person in whose name the building
permit has been issued pursuant to Section 105 shall obtain the certificate
of occupancy and shall prevent the occupancy of any building or structure
or part thereof until such certificate is issued to him/her. Issuance
of a certificate of occupancy shall not be construed as an approval
of a violation of the provisions of this code or of other ordinances
of the jurisdiction.
44.
111.1.1 Use and occupancy for existing buildings. Upon written request from the owner or prospective tenant of an
existing building or structure, the Code Official shall issue a certificate
of occupancy, provided that there are not violations of law, or this
code, or orders of the Code Official pending, or which are found to
exist upon an inspection of the building, and it has been established
after inspection and investigation that the alleged occupancy is also
in conformance with the Zoning Ordinance of Creve Coeur, Missouri.
This code shall not require the removal, alteration, or abandonment
of, or prevent the continuance of, the occupancy of a lawfully existing
building or structure, unless such use is deemed to endanger public
safety and welfare. Issuance of a certificate of occupancy shall not
be construed as an approval of a violation of the provisions of this
code or of other ordinances of the jurisdiction.
45.
111.1.2 Use and occupancy for existing residential occupancy. The requirements of Section 111.1.1 shall not be applicable to existing
one- and two-family residential buildings and residential structures

of this code and shall subject said owner or tenant to penalties as
set forth in Section 114.4.
47.
111.4 Revocation of the certificate of occupancy. The certificate of occupancy shall always be subject to this code
and other laws enforced by the Building Official. Non-compliance with
the regulations of this code and other laws enforced by the Building
Official shall be deemed a violation subject to the penalties set
forth herein, and, in addition, the Building Official shall be empowered
to revoke the certificate of occupancy issued for the building in
question, until such time as the violations are corrected and the
building is in compliance with this code and the Zoning Ordinance
of Creve Coeur, Missouri. The issuance of a certificate of occupancy
shall not relieve the owner or tenant from compliance with all regulations
of this code and other applicable regulations.
48.
111.5 Permanent address numbers. Every dwelling
unit or business structure within the City of Creve Coeur shall have
the correct street number(s) permanently affixed on said dwelling
unit or business structure so as to be clearly visible from the street

and the remaining capacity of such affected elements, with respect
to all dead and live loads, is less than seventy-five percent (75%)
of that required by this code for new buildings of similar structure,
purpose and location.
|
TECHNICALLY INFEASIBLE
An alteration of a building or a facility that has little
likelihood of being accomplished because the existing structural conditions
require the removal or alteration of a load-bearing member that is
an essential part of the structural frame, or because other existing
physical or site constraints prohibit modification or addition of
elements, space or features which are in full and strict compliance
with the minimum requirements for new construction and which are necessary
to provide accessibility.

increased load required by this code for new structures. Any existing
gravity load-carrying structural element whose gravity load-carrying
capacity is decreased shall be considered an altered element subject
to the requirements of Section 3404.3. Any existing element that will
form part of the lateral load path for any part of the addition shall
be considered an existing lateral load-carrying structural element
subject to the requirements of Section 3403.4.
11.
3403.3.1 Design live load. Where the addition does
not result in increased design live load, existing gravity load-carrying
structural elements shall be permitted to be evaluated and designed
for live loads approved prior to the addition. If the approved live
load is less than that required by Section 1607, the area designed
for the nonconforming live load shall be posted with placards of approved

otherwise altered as needed to carry the increased gravity load required
by this code for new structures. Any existing gravity load-carrying
structural element whose gravity load-carrying capacity is decreased
as part of the alteration shall be shown to have the capacity to resist
the applicable design gravity loads required by this code for new
structures.
17.
3404.3.1 Design live load. Where the alteration
does not result in increased design live load, existing gravity load-carrying
structural elements shall be permitted to be evaluated and designed
for live loads approved prior to the alteration. If the approved live
load is less than that required by Section 1607, the area designed
for the non-conforming live load shall be posted with placards of
approved design indicating the approved live load. Where the alteration
does result in increased design live load, the live load required
by Section 1607 shall be used.
18.
3404.4 Existing structural elements carrying lateral load. Except as permitted by Section 3404.5, where the alteration increases
design lateral loads in accordance with Section 1609 and 1613, or
where the alteration results in a structural irregularity as defined
in ASCE 7, or where the alteration decreases the capacity of any existing
lateral load-carrying structural element, the structure of the altered
building or structure shall be shown to meet the requirements of Sections
1609 and 1613.
Exception: Any existing lateral load-carrying structural
element whose demand-capacity ratio with the alteration considered
is no more than ten percent (10%) greater than its demand-capacity
ratio with the alteration ignored shall be permitted to remain unaltered.
For purposes of calculating demand-capacity ratios, the demand shall
consider applicable load combinations with design lateral loads or
forces per Sections 1609 and 1613. For purposes of this exception,
comparisons of demand-capacity ratios and calculation of design lateral
loads, forces, and capacities shall account for the cumulative effects
of additions and alterations since original construction.
