Most fully permitted, site-built ADUs fall in the low to mid six figures.

Costs vary widely based on real site conditions, not just size or finishes.

The biggest cost drivers are:

• Utilities and trenching distance

• Site access and slope

• Permitting and jurisdictional requirements

Because these vary by property, we don’t publish fixed prices.

A site-specific cost range gives you a realistic starting point early.
