Granny pods in Utah
A granny pod is a small detached granny flat: its own living space in the yard, usually for a parent or other family. Utah cities regulate it as a detached accessory dwelling unit.

Granny pod, granny flat, and ADU
Homeowners use granny pod for a compact backyard unit and granny flat for a family suite that might be inside the house, attached, or detached. The permit name is accessory dwelling unit. If the unit is a separate structure, use the detached rules, not the internal-ADU rules.
Wasatch Front planning bands are often about $55,000–$145,000 when the suite stays inside the house and $95,000–$250,000 or more for a new detached pod, before hillside work or long utility runs.
Lot size
Many cities may still say no to an internal ADU on a lot of 6,000 sq ft or less. A detached unit on a qualifying single-family lot of about 11,000 sq ft follows the statewide floor beginning October 1, 2026. Local height, setbacks, design, and owner-occupancy rules still apply. Smaller lots depend on the city.

It can be, when the city allows a detached accessory dwelling unit on that lot. A granny pod is not a separate permit category from a detached ADU.
How much does a granny pod cost in Utah?
Plan a new detached unit around $95,000–$250,000 or more before unusual site work. An internal family suite is often less because the shell of the house already exists.
