## Frequently asked questions

### How much does adu cost?

Most adu falls between $1,418 and $4,396, with a typical figure near $2,497 per job. The low end is a straightforward job with no surprises; the high end covers complex scope, premium materials or urgent timing. For Wilmington, ask a provider to put that in writing with the quote.

### Is ADUs cheaper in smaller cities?
