An ADU is a zoning project before it is a construction project. Setbacks, lot coverage, parking relief, owner-occupancy rules and utility capacity decide what can legally go on your lot, and they vary street by street.
Utilities are the line item that surprises people: whether your existing panel and sewer lateral can carry a second dwelling, or whether you are trenching to the main.
Long cooling seasons and heavy summer rain drive the two problems we see most here: moisture getting into assemblies, and anything that traps it staying wet.
What the job includes
- Zoning and feasibility review
- Plan sets and permit submittal
- Detached, attached and garage conversions
- Separate utility metering
- Kitchen and bath rough-in
- Final inspection and occupancy sign-off
Homes in Memphis and adu construction work

Memphis has a mixed housing stock: 60% detached houses, 5% attached or townhouse units and 26% in buildings of five or more units.1 On a mixed stock, feasibility turns on the individual lot - detached houses on larger parcels are the usual candidates; attached homes rarely qualify.

Owners and renters are roughly balanced in Memphis, with 45% of occupied homes owner-occupied (67% statewide).1 Where most occupied homes are rented, ADU inquiries often come from owners of rental property; the feasibility review is the same. The stock is old by national standards: 67% of Memphis's housing units were built before 1980 (U.S. 50%), and only 5% since 2010.1 Older lots often have existing detached garages, the usual candidate for a conversion; the slab height and moisture barrier decide the real scope.
Memphis sits in IECC climate zone 3A (Mixed-Humid).4 In a mixed climate zone, the energy code balances heating and cooling; insulation levels and window ratings are set by the zone. The median owner-occupied home in Memphis is valued at $169,000 (ACS), below the Tennessee median of $286,700.1 With values below the state median, phased scopes - the essential work first - are a common way to keep a project sensible.
