Accessory Dwelling Units by Sublime Contracting
As Boise and Meridian, Idaho continue to grow, homeowners are looking for practical ways to add value and flexibility to their properties. One increasingly popular solution is the construction of an Accessory Dwelling Unit (ADU) — a self-contained secondary residence built on the same lot as a primary home. Sublime Contracting has been helping homeowners across the Treasure Valley achieve this goal for over 25 years.
An ADU — sometimes referred to as a backyard cottage, in-law suite, or secondary suite — is a versatile housing option that can serve many purposes. Whether the goal is to house aging family members, generate rental income, or create a private workspace, an ADU offers a functional and adaptable solution. In Ada County and the surrounding region, these units are becoming more common as housing demand and multi-generational living needs continue to rise.
Sublime Contracting serves homeowners in Boise, Meridian, Eagle, Garden City, Kuna, Nampa, Twin Falls, Caldwell, Emmett, Payette, Mountain Home, Weiser, Hailey, and Jerome, among other nearby communities.

Benefits of Adding an ADU to Your Property
There are several practical reasons homeowners in the Boise and Meridian area choose to build an accessory dwelling unit:
- Increased Property Value: An ADU adds usable living space to a property, which can positively affect its market value and appeal to a broader range of buyers.
- Multi-Generational Living: ADUs provide independent living quarters for aging parents, adult children, or other family members, supporting privacy while keeping family close.
- Rental Income: A well-designed ADU can serve as a rental unit, offering a source of passive income that may help offset mortgage or maintenance costs.
- Flexible Use: These units can function as home offices, guest suites, studios, or hobby spaces, adapting to changing household needs over time.
- Aging in Place: An ADU can be designed with accessibility features, providing a practical alternative to assisted living while allowing homeowners to remain in familiar surroundings.
- Sustainable Land Use: ADUs make efficient use of existing lots, reducing the need for outward development and supporting more compact, sustainable urban growth.
Common questions about ADUs include topics such as legality, cost, utility connections, and property tax implications. In general, ADUs are permitted under local zoning regulations when they meet size, setback, and occupancy requirements. Construction timelines typically range from three to six months depending on project scope, and most units require independent utility connections for plumbing, electricity, and HVAC systems.
With more than 25 years of experience in the region, Sublime Contracting brings practical knowledge of local building codes, design considerations, and construction methods to each ADU builder project they undertake. Their work as an accessory dwelling unit builder covers the full process — from initial design and permitting through to final construction and interior finishing.
