Two details to plan around: the ADU counts toward your lot coverage, and if the project takes away a garage stall, Saratoga Springs wants that stall replaced. Our tracker doesn't spell out one-story setbacks yet, so we confirm them with the city for your lot.
Which Cocoon floor plans fit Saratoga Springs's rules
| Plan | Size | Fits Saratoga Springs's size rules? | Added parking |
|---|---|---|---|
| 100 Series studio (home ~$63K) | 170 sq ft | Yes, if your house is larger than 170 sq ft | 1 added stall |
| 200 Series one-bed retreat (home ~$73K) | 240 sq ft | Yes, if your house is larger than 240 sq ft | 1 added stall |
| 300 Series one-bedroom, most popular (home ~$84K) | 300 sq ft | Yes, if your house is larger than 300 sq ft | 1 added stall |
| 400 Series flex (home ~$94K) | 400 sq ft | Yes, if your house is larger than 400 sq ft | 1 added stall |
| 500 Series two-bedroom (home ~$109K) | 500 sq ft | Yes, if your house is larger than 500 sq ft | 1 added stall |
| The ADU also can't be taller than your house and has to fit your lot coverage; we confirm both for your lot before design. | |||
Most owners go wider or add square footage; custom footprints up to Saratoga Springs' cap (no larger than your house, within your lot coverage) are available, and we size them to the rules before design. A second story changes the setbacks: side and rear setbacks then equal the ADU's height.
What an ADU costs in Saratoga Springs
A Cocoon ADU in Saratoga Springs generally runs $85,000–$200,000 all-in. On top of the home price, expect site work, utilities and city costs to add 35–50%, including city fees that typically run $3,500–$9,000. The 300 Series one-bedroom is about $113,000–$126,000 all-in. If the ADU displaces a garage stall, replacing it is part of the site work, so we flag it at the lot check. A traditional custom-built ADU costs $200,000–$400,000 or more. Breakdown: Utah ADU costs.
