IRC Floor Plan Engineering & Cost Methodology
HoolieHaus was built to solve the biggest frustration in residential design: floor plan websites that publish unbuildable concept sketches without real room dimensions, wet-wall consolidation, or realistic shell kit pricing. Every one of our 2,462 floor plans is audited against 2024 International Residential Code (IRC) standards.
