ADU Construction in Las Vegas
Accessory Dwelling Units — Guest Houses, Casitas & In-Law Suites
Overview
CERA Construction designs and builds accessory dwelling units (ADUs) throughout Las Vegas and Clark County. Whether you need a backyard guest house, a garage conversion, a detached casita, or an in-law suite, our design-build team handles every step — from feasibility studies and permitting through construction and final inspection. ADUs are one of the fastest-growing segments in Las Vegas residential construction because they add flexible living space, generate rental income, and increase property value.
Clark County and the City of Las Vegas updated their ADU ordinances to make building accessory dwelling units easier and more affordable. CERA Construction stays current on all local zoning requirements, setback rules, utility connection standards, and HOA covenants so your ADU project moves smoothly through the approval process. Our licensed contractor team has built ADUs in Henderson, Summerlin, North Las Vegas, Enterprise, Spring Valley, and throughout the Las Vegas Valley.
Whether you envision a 400-square-foot studio casita or a full two-bedroom guest house, CERA Construction brings the same quality craftsmanship, premium materials, and transparent pricing to every ADU project that we deliver on our large-scale luxury remodels and custom homes.
