Expert ADU Construction in Summerlin, NV
Ness Construction handles ADU construction for Summerlin and Las Vegas homeowners from design through final inspection. An ADU, also called a casita or in-law suite, is a self-contained unit on the same lot as your primary home. It includes its own kitchen, bathroom, living area, and private entrance. We build detached backyard units, attached additions, and garage conversions. Summerlin sits within the Las Vegas metro, where ADU projects must meet the City of Las Vegas Unified Development Code or Clark County rules depending on your parcel. Many Summerlin properties also fall under HOA guidelines, so we review those requirements before design begins. Our team handles zoning review, plan preparation, and code compliance so nothing gets missed. Las Vegas construction must meet the 2021 International Building Code, including structural, egress, and energy standards. Whether you want space for aging parents, a long-term rental, or a private home office, we build units that work for your property and your goals. Contact Ness Construction to schedule a site review.
