Catalog & CAD Engineering FAQ
Frequently Asked Questions About StructuraCAD Floor Plans
Are all 1,674 floor plans in the HoolieHaus StructuraCAD catalog free to download?
Yes. Every floor plan in our catalog includes a free downloadable scalable vector CAD blueprint (.SVG) with exterior overall dimension strings, room-by-room square footage callouts, door swing arcs, and window schedules, plus a printable architectural specification and material takeoff sheet.
How are the 2D CAD floor plans verified for IRC residential building codes?
Every layout is generated and audited by our deterministic spatial solver against 2024 International Residential Code (IRC) standards—verifying R304 minimum habitable room areas (70+ sq ft and 7'-0" minimum width), R310 bedroom emergency egress windows, 36-inch primary entry doors, consolidated wet-wall plumbing cores, and unobstructed doorway walkthrough clearances.
What building footprints and structure styles are covered?
Our catalog spans 12 residential and accessory structure styles (Barndominium, Backyard ADU, A-Frame Cabin, Modern Cabin, Tiny Home on Foundation, Garage with Apartment Above, Shop House, Duplex, Single-Story Ranch, Container Home, Pole Barn Home, and Modular Cottage) across 80 standardized structural footprints from 12'×24' (288 sq ft) up to 50'×70' (3,500 sq ft).
