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 Richmond and adu construction work
Public figures for the city of Richmond in Richmond city, not the metro, and the general practice that follows.
Richmond has a mixed housing stock: 44% detached houses, 8% attached or townhouse units and 35% 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. Building permits in Richmond are normally issued by the city, which is not part of a county.2,3 ADU plan review and permits go through the city building department; the contractor prepares the plan set and submits it.
Owners and renters are roughly balanced in Richmond, with 44% 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: 71% of Richmond's housing units were built before 1980 (U.S. 50%), and only 11% 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.
Richmond sits in IECC climate zone 4A (Mixed-Humid).4 In this climate zone the energy code sets wall and ceiling insulation levels that a conversion must meet. The median owner-occupied home in Richmond is valued at $353,000 (ACS), below the Virginia median of $383,700.1 With values below the state median, phased scopes - the essential work first - are a common way to keep a project sensible.
Heating dominates the year: about 3,736 heating degree days against 1,560 cooling degree days (base 65°F).5,6 In a heating-led climate, insulation and air sealing carry most of the energy-code weight for any work that opens the envelope.
