If you’re budgeting a detached garage construction in Denver, most projects run $21,017-$63,051, 5% above the $35,000 national average. What moves that number most is usually one thing: Size and Number of Bays. On its own it can swing the cost by $10,000 - $40,000, so that’s the decision to slow down on before you sweat the smaller stuff.

Easiest place to save: Get engineering plans done once and use competitive bidding to get the best framing price. Having your own plans lets you get apples-to-apples bids from multiple framing contractors.
