Tiny Home Shells & Sheds Near Anna, TX

Outside city limits, including the ETJ: Collin County has no zoning in unincorporated areas, but it requires a Development Permit for projects that add footprint to a parcel, and it names barns and storage buildings as examples. Apply through the county's Citizen Self-Service Portal. Properties in a city's extraterritorial jurisdiction (ETJ) still permit through the county, and new construction there also needs an ETJ Verification form signed by that city. The county notes that review can take up to 30 days, so apply before you schedule delivery.

A few county rules worth knowing: structures can't be built in drainage easements, residential structures aren't allowed in the floodplain, and addresses are only assigned through permitting. If the building will connect to septic, the on-site sewage facility (OSSF) review runs through the same development permit. Collin County Development Services is at (972) 548-5585.

Inside Anna city limits: the city exempts one-story detached accessory buildings under 200 square feet with no electrical, plumbing, or mechanical work from a permit, though setbacks still apply. Larger buildings need an accessory/storage building permit ($125 on the city's fee schedule). Accessory buildings must sit at least 5 feet from side lot lines and 10 feet from the rear, stay out of platted easements, and top out at 18 feet tall.
