Do I need a permit for shed or accessory structure in Tomball?
It depends. Whether shed or accessory structure needs a permit in Tomball comes down to the details of your project.
Many Texas cities exempt small accessory buildings. Dallas, for example, exempts a utility building under 200 square feet with no electrical, plumbing, or gas on single-family or duplex premises, but running utilities to a shed or exceeding the size threshold triggers a permit. Zoning setbacks and easement restrictions still apply even when a building permit is not required, so verify placement with your local building department. Tomball's Unified Development Code section 2.02.H requires a Building Permit for all structures in all zoning districts. The only stated exception is an accessory structure under 200 square feet. Under UDC section 2.05.D, an accessory building cannot exceed 50 percent of the floor area of the main building or the main building's height, cannot sit in an easement, and cannot be built before construction of the main building has begun. In residential districts, accessory buildings are prohibited in front of the main building and must be at least 3 feet from the rear lot line or alley, except in the AG and SF-20 districts, where they must meet main building setbacks. One placed within 10 feet of the main building must meet the main building's rear setback.
