Innovative Building Materials and Net-Zero Technology
ResCom ADU sets itself apart through its use of Structural Insulated Panels (SIPs) — a revolutionary building system consisting of a solid core of expanded polystyrene (EPS) structurally laminated to two oriented strand board (OSB) skins. This system provides:
- Superior structural integrity
- Excellent thermal insulation
- Interior and exterior sheathing in one system
- Built-in electrical conduit pathways
In addition to SIP construction, ResCom ADU utilizes the latest Net-Zero Construction Technology, which significantly reduces the cost of heating and cooling the unit. This technology is also available for the client's main property, making it a smart long-term investment.

As an experienced granny flat builder and in-law suite builder, ResCom ADU understands that every client has different goals.

Their ADUs are suitable for a variety of purposes, including:
- Housing for extended family members
- Home office or remote work space
