Do I need a permit for screen enclosure or pool cage in Warner Robins?

Most likely yes. Screen enclosure or pool cage usually requires a permit in Georgia. Confirm the specifics with Warner Robins.

A screen room or patio cover attached to the house is a structure that generally needs a permit and setback review; a freestanding, non-roofed screen may be treated more lightly by some jurisdictions. Adding a roof cover can trigger structural, drainage, and (if enclosed) electrical review. Houston County's own permitting office is the Houston County Building Inspection and Planning and Zoning office, reachable on 478-542-2018 at https://www.houstoncountyga.gov/business/building-inspection.cms. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Georgia municipalities do not, this is the office that will handle the job. An attached enclosure is a structural addition, so expect a plan review and a footing and attachment inspection. Under Zoning Ordinance Section 93.2, any roofed accessory structure over 20 square feet needs a city building permit, must be in the rear yard, and must stay at least 5 feet from side and rear lot lines. Under Section 93.1.6, an accessory structure joined to the house by a common wall at least 4 feet long, or by a roofed passageway at least 8 feet wide, counts as part of the main building and must meet the main building's setbacks.
