Completed Project in Centennial, Colorado

Attached ADU In-Law Suite in Centennial, Colorado

ADU/In-Law Suite in Centennial, CO 80121. Completed and passed all city inspections.

This project was built as a mother-in-law suite for a retired mother who had lived in an RV for many years. Because detached ADUs were not allowed in the subdivision, Custom Sunroom created an attached addition solution connected to the existing home.

Pain / Purpose

The purpose of the project was mother-in-law suite construction. A retired mother had lived in an RV for many years before the family decided to build a dedicated house addition for her.

  • Mother-in-law suite construction
  • Long-term private living space for a retired mother
  • ADUs were not allowed in the subdivision

The Solution

Custom Sunroom offered a solution to build the ADU as an attached version connected to the house, so the project could move forward through the city process and pass inspections.

  • Attached addition connected to the existing home
  • 450 sq ft studio-style suite
  • Bedroom, bathroom, laundry unit, and kitchenette

Status / Result

The project was completed and passed all city inspections. The finished attached ADU includes two entryways: one toward the backyard and one toward the private sidewalk leading out of the property.

  • Completed and passed all city inspections
  • Two entryways for practical daily access
  • The homeowner finally moved into a house of her own
