Approved: one-bedroom accessory dwelling unit with shop behind a Boise home
The city approved a single-story detached shop with a one-bedroom accessory unit of about 897 square feet at the rear of the lot. The gravel driveway must be paved and buffered, and the shop may not be used commercially.
From the filing
The application's description as it appears in City of Boise's record. See the official record
The owner of 1164 S Wild Phlox Way in Boise received approval to build a 1,677 square foot single-story detached shop with a one-bedroom accessory dwelling unit of about 897 square feet at the rear of the lot. The house will still look like a single-family home from the street, and the existing gravel driveway was recognized as a legal nonconforming feature.
