The cost of a home addition depends on the size of the project, design, finishes, structural requirements, site conditions, and permitting. LJ Builders starts by understanding your goals and property before developing a scope and budget for your specific addition.
LJ Builders builds custom home additions designed around the homeowner and existing property. Projects can include additional bedrooms, expanded living areas, home offices, guest spaces, primary suite additions, and other custom expansions.
Most home additions require permits and must meet applicable building and zoning requirements. Requirements vary by property and municipality. LJ Builders helps guide the planning and permitting process as part of your project.
Timelines vary based on the size and complexity of the addition, design and permitting requirements, material selections, and site conditions. Before construction begins, LJ Builders establishes the project scope and communicates what to expect throughout the build.
LJ Builders serves homeowners throughout the Phoenix East Valley, including Scottsdale, Mesa, Tempe, Chandler, Gilbert, and surrounding communities. Looking for a separate living space on your property? Explore our custom casita and ADU construction services.
