Do I need a permit to pour a slab for a shed or backyard building in Richardson?
The building needs one if it's over 40 square feet, because the city issues permits for every accessory structure over that size. At 150 square feet or less the application needs a sketch showing where it goes, and over 150 it needs scaled drawings. A detached building also has to sit at least 7 feet from the side property line unless it's entirely in the rear yard, the back 25 feet of the lot, and your zoning can ask for more, so I measure that before we set forms.
