Travis County has limited zoning power under Texas Local Government Code Chapter 240, so unincorporated areas have no mansionization caps; size limits exist mainly in city extraterritorial jurisdictions and platted subdivision deed restrictions.
Texas counties cannot impose floor-area ratios, height caps, or bulk-control rules countywide. Travis County reviews building permits under Chapter 64 for life-safety and septic capacity rather than size. Many platted Hill Country subdivisions enforce private deed restrictions limiting square footage, height, or impervious cover. Cities like Austin and Lakeway apply mansionization caps within their corporate limits and ETJ. Septic capacity and Edwards Aquifer impervious-cover rules indirectly cap home size on small rural lots, especially over the recharge zone.
No county-level fines for size, but septic and Edwards Aquifer rule breaches carry TCEQ civil penalties; HOA deed-restriction enforcement happens through private litigation.
