Building requirements
Building a house in Round Rock, TX: what the code requires
Statewide code, local enforcement varies
- Building code
- State law makes the IRC the residential code in cities. Counties have limited authority, so many unincorporated rural areas have no building permits or inspections.
- Energy code
- The IECC-based energy code applies in cities, and some cities (Austin) have stricter local codes.
- Climate zone
- IECC climate zone 2–4. Insulation, windows and HVAC are sized to match.
- Typical frost depth
- 0–6 in (south), 12–24 in (north/Panhandle). Footings must extend below the local frost line (confirm with your building department).
- Foundations
- Raised or pier foundations where flood zones apply; slab inland.
- Who can draw the plans
- Single-family homes can generally be designed by a non-licensed home designer. A licensed engineer's stamp is often required for structural items, engineered foundations or special hazard zones, or when the local building official asks for it.
- Engineer stamp
- If your jurisdiction requires sealed drawings, add our Texas Engineer Stamp / Permit-Ready package ($1,000).
Texas-specific rules & hazards
- The 14 coastal counties require Texas Department of Insurance windstorm (WPI-8) certification to qualify for TWIA insurance.
- Expansive clay soils (Dallas–Fort Worth, Austin, San Antonio) often require an engineered post-tension slab.
- High-wind and hurricane design (uplift connections, impact-rated openings)
- Tornado-resistant framing, with safe-room options
- Flood-zone elevation and coastal foundation requirements
Summary for planning only. Codes, editions and local amendments change, so always confirm current requirements with the building department that will issue your permit. Our designers check your jurisdiction before drawing.
