Building codes & your state

Please read before ordering. Our plans are drawn to 2021/2022 IRC standards. They do not include site-specific earthquake seismic or wind engineering (CA, OR, WA, NV residents take note). Coastal GA, SC & NC may require hurricane/wind engineering. Many states (incl. FL, NY, NJ, CO, PA and others) may require a locally licensed engineer or architect to review and seal plans before permitting. Call your local building department before placing your order — and remember our editable CAD files are designed to make that local review fast and inexpensive. Need help? Our engineering-stamp coordination service connects you with a licensed professional in your state.
