How much does it cost to build an ADU in Milton?

An accessory dwelling unit in Milton costs whatever the specific project requires, driven mainly by size, whether it's new construction or a conversion, finish level and site conditions, which is why no flat figure applies across every Milton lot. A garage or basement conversion generally costs less than new detached construction on a large Milton property. Get quotes from a licensed contractor and confirm zoning and permit requirements with Milton's building department before budgeting a specific number.
