In determining whether dwelling accommodations are decent, safe, and sanitary, the governing body may take into consideration the degree of deterioration, obsolescence, or overcrowding, the percentage of land coverage, the light, air, space, and access available to inhabitants of such dwelling accommodations, the size and arrangement of rooms, the sanitary facilities, and the extent to which conditions exist in such buildings which endanger life or property by fire or other causes.
