S²A Modular

California factory-built modular ADUs and GreenLux residences, designed around energy-conscious living.

S²A Modular is a California manufacturer founded in 2018, operating a Patterson MegaFactory for factory-built modular ADUs, custom GreenLux residences, multifamily, and commercial projects. Its current ADU range spans compact 350 sq ft plans through 1,182 sq ft two-module homes. S²A does not publish a current public price list; each project is scoped through a Development Feasibility Study and Conceptual Budget. The company’s advertised modular price excludes the on-site and logistics work buyers often mistake for an all-in price, so the written project scope deserves particular attention.

How to use this profile

This profile presents S²A Modular as a research starting point for modular, adu, residential, single-family, sustainable buyers. It combines the provider's published location, build method, delivery framing, named-model records, and any cited independent tours in one place so that a buyer can see both the useful details and the questions that remain.

For this provider, begin by choosing the specific model or program that fits your intended use, then compare its written factory or plan scope against the site work and local services your project will need. Ask who owns responsibility for engineering, permits, foundation, transport, setting, utilities, final completion, warranty response, and support after handoff. A listing or state chip is never an address-specific commitment.

Keep the provider's written answer with the proposal. It makes it easier to compare S²A Modular with other builders on scope and responsibility rather than a headline number alone.

Named models

Each listed model has a separate source record. An image is displayed only when its provider or tour context identifies the same model; otherwise the model remains a factual card.
