Your floorplan is the single most important decision in an ADU project. It drives your square footage, your permit path, your build cost, and how much rent you can charge. ADUMetrics lets you get it right first — design freely, iterate instantly, and only commit once the layout truly works for your lot and budget.
A simple path from idea to a build-ready ADU.
California ADU rules turn on setbacks, lot coverage, and height — so a layout that looks great in the abstract can be impossible on your actual parcel. Our builder lets you shape the unit against the constraints that matter, so the plan you fall in love with is one you can actually permit.
When you are ready, send your sketch for a plan review and our planners will check it against your city's standards before you spend a dollar on permit drawings.
A clean floorplan is the foundation for everything that follows: a realistic 3D walkthrough, an accurate contractor scope, and a financing estimate that reflects the real size of the project. Designing first — before you talk to a builder — keeps you in control of scope and cost.
Everything you need to plan, design, and build your ADU — start to finish.
