Architectural templates for residential home

New to Sketchup (old AutoCAD user) I’m looking for some architectural templates; site plan, floorplan, elevations, notes, title blocks etc. so I do not have to start my home addition drawings from scratch. Where can I get these?
If they are for Maricopa county that would be perfect but any state would do.

I don’t know of any templates like that. Especially not for a county or state. You can and should make your own templates for SketchUp and LayOut before you start your projects. FWIW, title blocks and notes go in LayOut, not in Sketchup.

wondering if their CADD files would provide some use?

or even reaching out to the building office?
