An ordinance, as that term is typically used, refers to a local law of a municipal corporation, duly enacted by the proper authorities, prescribing general, uniform, and permanent rules of conduct, relating to the corporate affairs of the municipality. Ordinances may be used for purely administrative purposes, such as to establish an office or set salaries. An ordinance can either regulate conduct or, for example, when establishing a crime, prohibit described conduct or actions altogether.
A resolution typically is less solemn and formal than an ordinance and, “generally speaking, is simply an expression of the opinion or mind of the official body concerning some particular item of business or matter of administration coming within its official cognizance. In practice, resolutions are often limited to expressions of opinion.
