Sitebuilt

Sitebuilt, or site-built, is a term used in construction and real estate to describe a structure that is built primarily at its final location using traditional on-site methods. It contrasts with manufactured, modular, or prefab homes, which are constructed in a factory and later transported and assembled at the site. Sitebuilt construction typically relies on local materials, conventional framing, and on-site coordination among trades.

Construction proceeds from design and permitting through foundation, framing, exterior and interior finishes, and final inspections. Local building codes, zoning rules, and inspections regulate the process. Because work occurs on the actual lot, site conditions such as soil quality, drainage, and weather can influence scheduling, methods, and costs. Customization is common, enabling adaptation to unusual lots or specific design goals.

Historically, most residential buildings were sitebuilt. The term gained prominence as factory-made and modular options increased in market share, providing a clear contrast between methods. Advantages of sitebuilt homes include full customization and on-site integration with the surrounding environment; disadvantages can include longer construction timelines and greater exposure to weather. Costs vary widely with design, materials, labor, and local regulations.

Synonyms include stick-built and on-site construction; the term is descriptive rather than prescriptive regarding architectural style.
