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.

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 in front of the property.

DEFINITIONS

7. 3402.1 Definitions. The following words and terms shall, for the purposes of this Chapter and as used elsewhere in the code, have the meanings show herein.

DANGEROUS

Any building or structure or portion thereof that meets any of the conditions described below shall deemed dangerous:

(1)	The building or structure has collapsed, partially collapsed, moved off its foundation or lacks the support of ground necessary to support it.
(2)	There exists a significant risk of collapse, detachment or dislodgment of any portion, member, appurtenance or ornamentation of the building or structure under service loads.

EXISTING STRUCTURE

A structure erected prior to the date of adoption of the appropriate code, or one for which a legal building permit has been issued.

PRIMARY FUNCTION

A primary function is a major activity for which the facility is intended. Areas that contain a primary function, include, but are not limited to, the customer service lobby of a bank, the dining area of a cafeteria, the meeting rooms in a conference center, as well as offices and other work areas in which the activities of the public accommodation or other private entity using the facility are carried out. Mechanical rooms, boiler rooms, supply storage rooms, employee lounges or locker rooms, janitorial closets, entrances, corridors and restrooms are not areas containing a primary function.

SUBSTANTIAL STRUCTURAL DAMAGE

A condition where:

(1)

In any story, the vertical elements of the lateral force- resisting system have suffered damage such that the lateral load-carrying capacity of the structure in any horizontal direction has been reduced by more than twenty percent (20%) from its pre-damage condition; or

(2)

The capacity of any vertical gravity load-carrying component, or any group of such components, that supports more than thirty percent (30%) of the total area of the structure's floor(s) and roof(s) has been reduced more than twenty percent (20%) from its pre-damage condition 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.

SECTION 3403

ADDITIONS

8. 3403.1 General. Additions to any building or structure shall comply with the requirements of this code for new construction.
