Permit-Ready House Plans (Engineered for California & Adaptable Nationwide)

Browse professionally engineered house plans designed for modern residential construction and permit approval. Each plan includes a complete architectural drawing set with options to upgrade to full structural design, including framing plans, lateral load systems, and structural calculations in accordance with applicable building codes (CRC, CBC, ASCE 7). Our house plans are developed with constructability, efficiency, and real-world engineering in mind. Optional foundation design packages include slab-on-grade and crawl space systems with detailed footing, anchorage, and connection design. For projects requiring permit approval, PE-stamped structural drawings and calculation packages are available, along with plan-check response support. These plans are engineered to California standards and can be adapted to meet local building codes across various U.S. jurisdictions. Suitable for custom homes, multi-story residences, and residential developments, each design balances architectural quality with structural performance and cost-effective construction.

Package tiers range from architectural-only plans to full engineering design with structural calculations, foundation systems, and permit support.
