In-Law Suite Facts
- ADU stands for Accessory Dwelling Unit. Many cities have recently relaxed zoning laws to allow ADUs to help combat the housing crisis.
- Converting an existing space (garage or basement) is significantly cheaper than building a detached structure because the roof, foundation, and exterior walls already exist.
- If you build a detached ADU, you will spend $10,000 - $20,000 just trenching the yard to bring water, sewer, and a new electrical subpanel to the structure.
