Secondary Dwelling Units Built to Code

ADU Remodeling in Salt Lake City for basement conversions to accessory dwelling units and interior upgrades for secondary rental properties with separate utilities

Salt Lake County zoning allows accessory dwelling units, but ADU conversions require separate electrical and plumbing runs, egress windows sized for emergency exit, and basement moisture management before interior layouts are reconfigured. Peaks Precision Remodeling handles full ADU interior remodels and basement conversions to accessory dwelling units across the Salt Lake City metro, managing permits in-house to ensure secondary dwelling units meet county egress and utility separation requirements. Elevation between 4,000 and 4,500 feet affects material durability from UV exposure, and basement moisture migration must be resolved before converting unfinished space to habitable ADU square footage.



The work involves reconfiguring interior layouts with egress windows that meet building code for bedroom spaces, running separate electrical and plumbing lines to create independent utility metering, and installing drywall and flooring materials suited for high-altitude UV exposure. Basement moisture management addresses water migration from seasonal snowmelt before finish materials are installed, preventing future damage to ADU living spaces.

What ADU Conversion Actually Accomplishes

ADU conversions begin with egress window installation sized to allow emergency exit without using interior stairs, followed by separate electrical service runs with dedicated breaker panels for independent metering. Plumbing is routed to create separate water and sewer connections, and basement moisture barriers are verified or replaced before framing and drywall installation begins. Material selection accounts for UV exposure at Salt Lake City's elevation, with flooring and finishes that resist fading and degradation from high-altitude sunlight penetrating windows.



After conversion is complete, you'll notice an ADU with separate utility metering that allows independent billing, egress windows that open fully for emergency exit, and interior finishes that maintain appearance despite UV exposure. Basement spaces remain dry during spring snowmelt because moisture barriers were addressed before conversion, and electrical panels provide dedicated circuits for tenant use without affecting the primary dwelling's service.


ADU remodeling includes interior layout reconfiguration, egress window installation, and separate utility runs, but does not include exterior foundation waterproofing or structural modifications unless specified in the project scope. Permit handling ensures ADU conversions meet Salt Lake County secondary dwelling requirements for egress, utilities, and occupancy standards.

Common Questions About This Service

ADU conversions in Salt Lake County raise questions about zoning compliance, utility separation, and basement moisture management before projects begin.

  • What egress requirements apply to ADU bedroom spaces in Salt Lake City?

    Building code requires egress windows with minimum opening dimensions and maximum sill height from the floor, allowing occupants to exit directly to grade in an emergency without using interior stairs or doors.

  • How are utilities separated for ADU conversions?

    Separate electrical and plumbing runs are installed with dedicated breaker panels and water meters, allowing independent utility billing for the ADU while maintaining service to the primary dwelling without capacity issues.

  • What moisture management is required for basement ADU conversions?

    Peaks Precision inspects existing moisture barriers and drainage systems before conversion work begins, addressing water migration from snowmelt or subsurface sources to prevent damage to finished living spaces.

  • How does elevation affect ADU material selection in Salt Lake City?

    UV exposure at 4,000 to 4,500 feet causes faster fading and degradation of flooring and finishes, so materials are selected for UV resistance and durability under high-altitude sunlight conditions.

  • How are ADU permits handled in Salt Lake County?

    Peaks Precision manages permits in-house, coordinating inspections to verify that egress windows, utility separation, and occupancy standards meet county requirements for secondary dwelling units.
