Summary
Unincorporated Miami-Dade County allows home occupations as an accessory use to a residence, but Section 33-25.1(A)(4) flatly bans any sign advertising one: no sign relating to the home occupation may be posted or displayed on the site, full stop. Operators still need an annually renewable Certificate of Use, and the county can inspect the property to confirm compliance.
(A)A home occupation shall be permitted as an ancillary use to all lawful residential uses subject to the following limitations:...4.Signage. No sign relating to the home occupation may be posted or displayed on the site....12.Certificate of Use. An annually renewable certificate of use and occupancy shall be obtained for any home occupation.13.Inspection. Upon the issuance or renewal of a Certificate of Use, the home occupation property shall be subject to inspection to ensure compliance with all applicable code requirements. At the time of application for the Certificate of Use, the occupant of the home shall provide a site plan that clearly delineates the location, configuration, and scale of the home occupation. If the location, configuration, or scale of the home occupation should change, a new site plan shall be submitted at the time the Certificate of Use is renewed.(B)No variances shall be granted through provisions of other applicable regulations which will in any way conflict with or vary the provisions of this section.

Full Breakdown
' There's no size or placement exception; the rule is a total prohibition rather than a size cap like most sign ordinances use. The signage ban sits alongside the rest of the home occupation limitations: the business can occupy no more than 25 percent of the dwelling's living area and garage space, capped at 500 square feet; no display, manufacturing, or repair of merchandise is allowed on the premises; and outdoor amplified sound is banned outright. To operate lawfully at all, the resident must obtain an annually renewable Certificate of Use under subsection (A)(12), and the property is subject to inspection at issuance or renewal under (A)(13) to confirm the home occupation matches the site plan on file; any change in location, configuration, or scale requires a new site plan at renewal.
Subsection (B) closes off the usual escape hatch: no variance may be granted from these home occupation limitations, including the sign ban, through any other provision of the code, so a homeowner cannot apply for zoning relief to post a sign. The provision was last amended by Ordinance No. '
Violations & Fines
Posting any sign for a home business, even a small one on the mailbox or in a window, violates Section 33-25.1(A)(4) and can jeopardize the home occupation's Certificate of Use; combined with other code enforcement, violations are cited and penalized under Chapter 8CC, which authorizes escalating civil fines until the sign is removed and the property is brought back into compliance.
