Planning budget ranges for ADUs and additions

Think in ranges, not exact numbers at first

Early on, it is more useful to think in budget ranges instead of fixating on a single number. Site conditions, finishes and design choices will all shift costs up or down.

Where costs tend to go

Detached ADUs generally cost more than attached additions of similar size. Conversions can be more efficient if the structure is solid and the layout works.

Why early planning calls help

A short planning call and site look can usually narrow the range enough for you to decide whether now is the right time or whether the project should stay on the future list for a bit longer.
