Deck Construction Permits in McKinney
Local Rule
City of McKinney Development Services
McKinney requires a building permit for any deck attached to the home, especially if it exceeds a certain square footage threshold; a freestanding deck over 30 inches above grade also needs one. A specific published small-deck exemption citation was not located directly on the city's own site, so the 200 sq ft / 30 in figures used here follow the general Texas baseline rather than a confirmed McKinney-specific number.
