What is Houston Chapter 42 and does it apply to my remodel?
Answered by AskBaily Editorial · Updated
Short answer
Chapter 42 of the Houston City Code is the Development Ordinance — Houston's de-facto substitute for zoning. It regulates minimum lot size (typically 5,000 sqft outside the 'urban area' and 1,400-3,500 sqft inside), setbacks, parking ratios, density, shared driveways, compatibility standards for adjacent properties, and open-space requirements. Interior-only remodels rarely trigger Chapter 42. Additions, subdivision, new footprint, or lot replat almost always do.
