Summary
A second house or mobile home on one Warner Robins residential lot is not a by-right accessory dwelling: it requires a special exception from the planning and zoning commission after a public hearing under zoning section 107. The extra dwelling must meet the same lot area, width and coverage rules as a stand-alone home and reach a public street by its own 15-foot-wide passageway.
Section 107. - Additional dwellings on a single lot. The planning and zoning commission, after review of an application and public hearing thereon, may grant a special exception to permit one (1) additional single-family dwelling, or mobile home on the same lot or parcel of land as that of the main dwelling provided that: 107.1. Each additional dwelling conforms to the minimum lot area, minimum width and maximum lot coverage requirements for such dwelling as set forth in section 81, and conforms to the yard requirements as set forth in section 82; 107.2. The arrangement of such additional dwellings are in such a manner that if the lot or parcel of land is ever subdivided, no nonconforming lots or nonconforming buildings are created; and 107.3. Each additional dwelling or mobile home has access to a public street by means of an unobstructed passageway of at least fifteen (15) feet in width.

Full Breakdown
Section 107 governs any second single-family dwelling or mobile home placed on a lot that already holds a main house, the closest thing Warner Robins' code has to an accessory dwelling unit process. Rather than a ministerial permit, it requires the planning and zoning commission to grant a special exception after reviewing an application and holding a public hearing, so approval is discretionary rather than automatic. Three conditions apply once a special exception is on the table. 2 dimensional table for that zoning district, and it must also meet the yard (setback) requirements of section 82, so the second dwelling cannot simply squeeze into whatever space is left after the main house's footprint and setbacks are accounted for.
2, the commission must be satisfied that if the lot were later subdivided into two separate parcels, one for each dwelling, neither resulting lot nor either building would become nonconforming, effectively requiring the applicant to show the arrangement could stand on its own under a future subdivision. 3, the additional dwelling or mobile home needs its own access to a public street through an unobstructed passageway at least fifteen (15) feet wide, so a unit tucked behind the main house cannot rely solely on sharing the principal driveway if that driveway is narrower than fifteen feet.
This section sits in Article X, Exceptions and Modifications, alongside the zero-lot-line and yard-modification provisions, underscoring that a second dwelling is treated as a deviation from the standard one-dwelling-per-lot pattern rather than a routine accessory use.
Violations & Fines
Placing a second dwelling or mobile home on a residential lot without first obtaining the section 107 special exception is enforced as a zoning violation under Section 116: the property owner faces the maximum punishment allowed under the City Charter, and each day the unpermitted second dwelling remains occupied or standing counts as a separate offense until the exception is obtained or the structure is removed.
