For Investors & Developers
Portfolio-Scale Permitting, Engineered for Volume
Building ADUs as an investment? QuiPlans is built for portfolio deployment — bulk engineering economics, multi-jurisdiction coverage, and permit coordination at scale.
Portfolio-Scale Permitting
Run multiple ADU projects in parallel — standardized plan sets and one engineering team coordinating every permit submission across your portfolio.
Bulk PE-Stamp Discounts
Volume pricing on engineering and PE-stamp orders. The more you build, the lower your per-project engineering cost gets.
Multi-Jurisdiction Capability
PE licensure across 25 states and multi-jurisdiction permitting support — one portfolio can span cities and counties without changing vendors.
Every Builder Package Includes the Permit Success Guarantee
A Complete Guaranteed Permit Package on Your First Home
Your one-time base fee covers the full package on an entry-tier home (up to a 700 sq ft ADU) — PE-stamped architectural, structural & MEP drawings, site plan, and permit submission support. If we don't secure your permit, you get a full refund. Every additional home gets your tier discount for 12 months.
Permit Success Guarantee for multi-property deployments. Qualifying projects across your portfolio are covered — de-risk large-scale ADU builds with the same guarantee single-project homeowners get.
