22.02.040 Additions, alterations or repairs.

(A) General. Buildings, structures and their building service equipment to which additions, alterations and repairs are made shall comply with all the requirements of the technical codes for new facilities, except as specifically provided in this chapter.
(B) Additions, Alterations or Repairs. Additions, alterations or repairs may be made to any building or its building service equipment without requiring the existing building or its building service equipment to comply with all the requirements of the technical codes, provided the addition, alteration or repair conforms to that required for a new building or building service equipment. Additions, alterations, or repair shall not be made to an existing building or building service equipment which will cause the existing building or building service equipment to be in violation of any of the provisions of the technical codes, nor shall such additions, alterations or repairs cause the existing building or building service equipment to become unsafe.
An unsafe condition shall be deemed to have been created if an addition, alteration or repair:
(1) Causes the existing building to become structurally unsafe;
(2) Does not provide adequate means of egress in compliance with the provisions of the building code of Clark County;
(3) Creates a fire hazard;
(4) Reduces required fire resistance;
(5) Causes building service equipment to become overloaded or exceed its rated capacity;
(6) Creates a health hazard or otherwise creates conditions dangerous to human life and safety.
Any building so altered, which involves a change in use or occupancy, shall not exceed the height, number of stories or area permitted by the building code of Clark County for new buildings. Any building plus new additions shall not exceed the height, number of stories, or area permitted by the building code for new buildings.
Additions and/or alterations shall not be made to an existing building or structure when such existing building or structure is not in full compliance with the provisions of the applicable building code in effect at the time of construction and the safety standards for existing buildings (22.10). Alterations or repairs to an existing building or structure which are nonstructural and do not adversely affect a structural member or a part of the building or structure having required fire resistance may be made with the same materials of which the building or structure is constructed, subject to approval by the building official. The installation or replacement of glass shall be as required for new installations.
Minor additions, alterations and repairs to existing building service equipment installations may be made in accordance with the technical code in effect at the time the original installation was made, subject to approval of the building official, and provided such additions, alterations and repairs will not cause the existing building service equipment to become unsafe, unsanitary or overloaded.
