(A) Bearing Capacity: Excavations for foundations shall extend to a level which will provide adequate bearing. In case of doubt regarding bearing capacity, tests may be required for this determination.
(B) Frost Line: Excavations shall extend below prevailing frost line and not less than thirty inches (30") below finished grade. Excavations shall not be less than twelve inches (12") below natural grade.
(C) Footing Trenches: The bottom of footing trenches shall be level and on undisturbed soil.
(D) Footing Projection: All footings shall be a minimum of eight inches (8") and four inches (4") projection on each side of foundation for width.
(E) Continuous Pour Concrete: All footings shall be of continuous pour concrete. When continuous pour is not possible, there shall be set midway in the break at the bulkhead, at least three (3) five-eighths inch by sixteen inch (5/8" x 16") steel rods.
(F) Basementless Houses:
1. In buildings using wood floors, where no basement is used, a crawl space of at least twenty four inches (24") shall be provided between the ground and the bottom of floor joists or support beams, whichever is lowest, and such ground shall be substantially level.
2. In buildings built on a slab, the slab shall be at least six inches (6") and with thickened edges. Such edges shall extend at least eight inches (8") above finished grade and at least thirty six inches (36") below finished grade, with a width of footing at least ten inches (10"). The slab shall rest on a porous fill of select materials, compacted, not less than six inches (6") in depth. All slabs shall be reinforced with at least a six inch by six inch (6" x 6") mesh of no. 10 steel wire, and footings shall contain at least three (3) five-eighths inch (5/8") steel rods. Between the slab and porous material shall be a vapor sheet of sufficient quality to withstand absorption of moisture.
(G) Ventilators: In all buildings using crawl space, ventilating openings shall be provided and covered with a metal mesh of under one-half inch (1/2") screen openings. All ventilators shall be at least six inches by twelve inches (6" x 12"), and at least two (2) shall be provided in each crawl space.
(H) Buildings On Slab: In small buildings on a slab, such separate building, other than a dwelling, not exceeding one story, constructed of either wood frame or concrete block construction and having less than five hundred (500) square feet of area, may be supported on concrete slab with thickened edges. Such edges shall extend at least eight inches (8") above finished grade and twelve inches (12") below finish grade. The slab shall be at least four inches (4") thick and shall rest on a porous fill of select materials not less than six inches (6") in depth. All slabs shall be reinforced with at least six inches by six inches (6" x 6") mesh of no. 10 steel wire.
(I) Detached Private Garages: Detached private garages may be supported on concrete slabs laid on the earth, when not attached to another building. Such slab shall be not less than four inches (4") thick, and placed on at least a base of porous material six inches (6") deep, and the slab shall extend at least two inches (2") above finished grade. (Ord. 267, 9-27-1961)
(J) Modular Dwelling: All tongues, wheels, axles and frames must be removed and may not be any part of the structure. (Ord. 550-B, 5-10-1995)
