Can I add an accessory dwelling unit (ADU) in Celina?
In most of Celina, no. Accessory dwelling units are prohibited everywhere except the AG, Agricultural district, the SF-E, Single-Family Estate district, and the Downtown Code (OT/OT-R) zoning district (Sec. 14.03.202(a)(2)). Where allowed, an ADU cannot exist without a main building already on the lot, cannot be sold apart from the primary residence, must share the primary structure's utility meter, must match its setback, height, and exterior materials, and is capped at the square footage of the primary dwelling with only one ADU allowed per lot (Sec. 14.03.202(a)(1)-(9)). A Planned Development may set different ADU rules for its area. Start by confirming the zoning district and any PD number on the city's public GIS (celina-public-gis-celinatx.hub.arcgis.com) or with Development Services at 972-382-2682. This pack covers incorporated Celina only; Celina's ETJ and unincorporated Collin or Denton county land have no municipal zoning.
