As of mid-2026 unincorporated Charlotte allows detached 'guest suites' but they may have living/sanitary facilities only — no cooking facilities — so they are not full rentable ADUs yet. Detached accessory structures are size-limited: on lots under 0.5 acre, total of all detached accessory structures cannot exceed 1% of parcel size or 1,000 sq ft (whichever greater); on lots 0.5 acre+, up to 3,000 sq ft total. County must add a true by-right ADU under state law by Dec 1, 2026. Punta Gorda self-governs.

Before You Build
ADU rules are set by each county and city — Florida law (Fla. Stat. 163.31771) lets local governments allow ADUs but doesn't require it — and they can change, so always confirm the current rule with Charlotte County before you build.
