Full Breakdown
Lee County's Land Development Code splits accessory space in two. Section 34-1173(b)(1) says an accessory building structurally part of the principal building must comply in all respects with the regulations for a principal building; if it is detached, Section 34-1174(d)(2) applies, requiring at least five feet from the rear property line and no closer to a side line than the district's side setback or ten feet, whichever is less. Making the space a separate living unit brings in Section 34-1177: one accessory apartment or accessory dwelling unit per principal single-family residence, living area capped at 60 percent of the main house, and one additional off-street parking space provided on site.
Violations & Fines
Unpermitted conversions are Land Development Code violations. Section 1-5(c) allows a fine up to $500 per offense with each day a separate offense; the Hearing Examiner may impose $25 to $1,000 per day under Section 2-427(a)(1).
