Key ADU Rules in Cutler Bay

All rules should be verified with Cutler Bay / Miami Dade County planning before committing to design costs.

Size Limits

Florida SB-48 (2026) sets a floor: municipalities cannot impose ADU size limits below 1,000 sq ft for applications that meet standard zoning criteria. Local limits may be lower — confirm with planning.

Setbacks

Setback requirements vary by zoning district. Contact Miami Dade County planning to confirm your parcel's exact requirements.

Parking

ADU parking requirements vary by zoning district and proximity to transit. Some districts allow parking waivers.

Rental Rules

Florida law restricts municipalities from requiring owner-occupancy as a condition of building or renting an ADU. Short-term rentals (under 30 days) may require a separate license.

SB-48 & Your Rights
