Every ADU is unique so we host regular question and answer sessions with expert panelists.

Carlos Plazola from BuildZig came by and did a brief presentation on sample costs, and our subscribers followed up with a whole range of questions.

Building an Accessory Dwelling Unit is an expensive project with a wide range of possible costs.

ADU construction expert Carlos prepared an ADU Cost one pager for How To ADU subscribers to understand how to think about costs and ROI for different types of ADU builds. Please keep in mind the rental, valuation and net equity columns are just one way to think about the value you’re creating - a lot of real estate markets don’t have enough ADU inventory to guarantee a cap rate for ADUs yet. This is a good starting point for thinking about your project, not a number written in stone.
