Townhomes and accessory dwelling units (ADUs) share a useful trait: compact, repeatable layouts. That makes them a natural fit for light gauge steel framing and prefabricated wall panels.
Why compact repeatable homes suit steel
When the same plan is built several times, wall panels can be modeled, produced and installed with little variation. Straight steel members keep openings square, and labeled components cut sorting time on tight sites.
Fire separation between townhomes
Party walls between townhomes need rated assemblies. Steel framing is non-combustible and is combined with gypsum board layers to achieve the rating in a tested assembly. Your architect and local officials confirm the details; see our fire resistance guide.
ADU considerations
ADUs are often built on constrained lots where delivery access and crane reach are limited. Panelized steel framing can arrive in manageable sizes and go up quickly. Check local rules for setbacks, utilities and permits early.
