Why 2026 Is the Year to Build an ADU
- Continued housing pressure: Rents and home prices remain elevated relative to incomes, making backyard cottages and garage conversions attractive for supplemental income and family use. Policy alignment: Municipalities across the Salt Lake Valley continue to refine ADU ordinances, easing parking, setback, and size restrictions, while clarifying permitting pathways. Financing innovation: Lenders are rolling out more ADU-friendly products—construction loans with interest-only periods, appraisal methods that account for projected rental income, and bundled design-build financing. Construction capacity: With steady activity among multi family construction companies in Salt Lake City, the local trades have robust experience with code compliance, energy efficiency, and rapid schedules—skills that translate well to small-footprint ADUs.
ADU Types to Consider in 2026
- Detached new-build: Standalone backyard cottages are ideal when lot width and setbacks allow. They offer the most privacy and rental potential. Attached addition: Adds square footage to an existing home with a separate entrance. Often faster to build and less costly for utilities. Garage conversion: A cost-effective option if the structure is sound and zoning permits. Careful planning is needed for insulation, ceiling height, and egress. Over-garage carriage unit: Pairs covered parking with living space above; pay attention to structural upgrades and stair egress.

Design Priorities for High-Performance ADUs
- Flexible layouts: Studio and one-bedroom designs with convertible spaces boost rental and resale value. Acoustic control: Use resilient channels, mineral wool insulation, and solid-core interior doors, especially for attached ADUs. Daylighting and privacy: Well-placed windows, clerestories, and screened patios maintain privacy for both households.

- Site work: Utility trenching, panel upgrades, and sewer connections often surprise first-time builders. Get a utility scope early.

Finish level: Durable, mid-grade finishes often pencil best for rentals—quartz, LVP, and tile in wet areas. Schedule risk: Weather, inspections, and change orders are the main delays. Detailed preconstruction and contingency planning mitigate these.
