Thinking about building a detached ADU? Here are the three biggest factors to check before you dive in:
1. Lot Size & ZoningMake sure your lot is big enough and zoned to legally support a detached ADU. Every city has minimum lot size requirements. Skip this step and you could be dead in the water.
2. Run the NumbersDetached ADUs often cost significantly more than attached or basement ADUs. Break down your build cost vs. potential rental income. In many cases, an attached ADU makes more financial sense.
3. Utility ConnectionsBudget for utility runs. Adding water, sewer, power, and gas to a detached unit can easily add tens of thousands to your project. Plan for it upfront so you’re not blindsided later.
