“Office, business or professional” means an office wherein business, technical or scientific services are rendered involving labor, skill, education and special knowledge for certain compensation or profit, but such labor, skill, education and special knowledge being predominantly mental or intellectual, rather than physical, manual or mercantile in nature. Examples of such uses would include, but not be limited to, the offices of lawyers, accountants, brokers, and insurance agents. (Ord. 1190-21 § 2, 2021).
