Backyard ADUs like this are being built across Naples — here's how to do it right.
What Naples's zoning may allow for an ADU
Naples permits an accessory 'guest unit' (up to 40% of the main home / 2,200 sq ft on large estate lots, 450 sq ft on smaller lots) but generally prohibits renting it separately from the main home — so it is not an income ADU in most cases. Confirm your district and lot size with the city.
Zoning allowance
A guest unit is permitted by right in the R1-E district and on any single-family lot of 30,000 sq ft or more; on smaller R1-15A, R1-15 and R1-10 lots it requires conditional-use approval.
Size limits
Naples regulates ADUs as 'guest units': up to 40% of the primary home, with no single unit over 2,200 sq ft on large lots (R1-E or ≥30,000 sq ft); on smaller lots the cap is 450 sq ft (Code §56-91).
Lot + setbacks
Setback requirements vary by zoning district in Naples. Confirm exact setbacks with Collier County planning.
Height + coverage
Height and lot coverage limits vary by zoning district. Check Naples zoning code.
Parking
Parking requirements for ADUs in Naples vary by zoning district. Verify with local planning.
Rental / occupancy
Naples guest units generally cannot be rented separately from the main home — leasing a guest unit is a zoning violation except for units built and rented before 1994 (Code §56-91). Treat this as a non-rental accessory unit.
Permit process
ADU permits in Naples follow standard Florida residential building permit workflow. Contact Collier County building department for current requirements.
