This ordinance was passed in the Austin, TX area and is officially called the Residential Design and Compatibility regulations. It was designed to minimize the impact of new construction, remodels, and additions to existing buildings on surrounding properties in residential neighborhoods by defining an acceptable building area for each lot within which new development may occur.
Depending on your home’s location, current size, and desired renovation, the McMansion ordinance can affect your remodeling project in Austin, TX. The McMansion ordinance is a law passed that applies to certain zip codes in the Austin Area. It is designed to limit the amount of livable space within the footprint of a property. This is meant to preserve the look and feel of Austin. Under this ordinance, the maximum amount of development permitted on a property is limited to 0.4 to 1.0 floor-to-area ratio OR 2,300 square feet of gross floor area, whichever is greater. For example,
- if your home is on a 10,000 sq ft lot, .4 of 10,000 is 4,000 sq ft. 4,000 is greater than 2,300 so the maximum amount of gross floor area allowed on this property is 4,000 square feet.
- If your home is on a 5,000 sq ft lot, .4 of 5,000 is 2,000 sq ft. 2,300 is greater than 2,000 so the maximum amount of gross floor area allowed on this property is 2,300 square feet.
