Pre-Approved (Shelf-Ready) Plans
Also: shelf-ready plans · standard plans
Pre-approved or shelf-ready plans are ADU designs a jurisdiction has already vetted for code compliance. Building from a pre-approved set can shorten plan check from the 60-day state maximum to roughly 30 days, and lowers design cost. The City of Sacramento and Sacramento County both publish pre-approved ADU plan programs.
Pre-approved plans trade some customization for speed and savings. They're ideal for standard lots; complex or sloped sites may still need a custom design.
