Martin County, FL Home Business: Zoning & Home Occupation Permits (2026)

Sec. 3, the glossary of the Martin County Land Development Regulations, defines a home occupation as any for-profit activity carried out within, or on the same lot as, a residential dwelling unit, by a resident of that dwelling unit. Sec. 955. ch. 205, and keeps its parking, and any hazardous-material storage, no more intensive than what a similar residence without a business would generate. Because the county's own ordinance simply cross-references the statute rather than layering on its own square-footage caps, employee limits or customer-visit restrictions, Martin County's home occupation rule is effectively as permissive as state law requires: a resident does not need a separate home occupation permit or site plan approval from Growth Management beyond whatever a Martin County Business Tax Receipt requires under the general code.

Article 3, Division 4's Sec. B still require that the home occupation, like any accessory use, be ancillary and incidental to the residential use and located on the same lot as the dwelling. Parking generated by the business cannot exceed what a similar residence without a business would produce, per the statute, and vehicles used for the business must be parked in legal, improved parking spaces off the right-of-way.
