Full Breakdown
Under ULDC Section 3.7.2, North Port permits one ADU per lot in every standard residential zoning district where the property has public water and sewer; without those utilities, an ADU is allowed only if it meets state-required septic/well separation distances, verified with the county health department. The unit must match the dimensional standards for accessory structures, comply with the Florida Building Code, and architecturally match the primary home. Size is capped at 65% of the primary structure's living area under air, with an 800-square-foot maximum. One additional parking space is required, and the ADU must share ownership with the primary parcel unless it independently meets all zoning-district requirements on its own.
Violations & Fines
Building an ADU without permits, exceeding the 800-square-foot/65% size cap, skipping the required extra parking space, or splitting ownership from the primary parcel violates North Port's zoning code and is subject to code enforcement.
