Draper didn't need SB284 to open up: its 6,000 sq ft lot minimum was already well below the state's 11,000. Our tracker doesn't yet carry Draper's size, height, setback or parking numbers for a D-ADU, so we confirm those against Draper's current code (through Ord. 1721) for your lot before design.

Most owners go wider or add square footage; custom footprints are available, and we size them to Draper's D-ADU standards before design. What Draper does publish on lot size is generous: a 6,000 sq ft lot qualifies, so many smaller Draper lots that fall short of the state's 11,000 sq ft line still work.
What an ADU costs in Draper
A Cocoon ADU in Draper typically comes in at $85,000–$200,000 all-in. Add 35–50% to the home price for site work, utilities and city costs, with city fees usually $3,500–$9,000. The 300 Series one-bedroom runs around $113,000–$126,000 all-in, against $200,000–$400,000+ for a traditional custom-built ADU. Your site work depends on how far the sewer, water and power have to run, so we price it at the lot check. See Utah ADU costs.
What an ADU rents for in Draper
We don't have a Draper-specific rent figure yet. Wasatch Front ADUs rent for $1,200–$2,500 a month, a typical one-bedroom $1,200–$1,500 (a regional range). At $1,300 a month, a $113,000 build pays back in about 7–7.5 years of gross rent. Draper lets the owner live in either the home or the ADU, so you can rent whichever one you don't live in.
