Is ADUs cheaper in smaller cities?

Often, but not always. Smaller markets can carry a travel or availability premium that offsets a lower local rate, so it is worth checking a nearby city before assuming the lowest published figure applies to you. In Irvine, that is worth confirming with a local provider before you commit.

How many quotes should I get for adu?

Two or three written quotes are enough to see the real market range. Compare the same scope side by side, and ask each provider what is excluded and what would change the price after the quote is accepted. The answer can shift with the Irvine market, so check locally.
