BIOS Homes

BIOS Homes offers panelized and modular construction for ADUs, tiny homes, and multi-family projects throughout Connecticut. Their Connecticut-specific pages cover Hartford, Fairfield, and New London counties, with published case studies showing completed ADU and tiny home builds.

Public Act 21-29 (Connecticut General Statutes § 8-2o) generally requires zoning municipalities to allow at least one accessory apartment on lots with a single-family dwelling as of right — a pathway BIOS markets toward. Per their website (as of May 2026), their process includes design, factory production, and site installation. Buyers should verify current permit requirements with their local planning department before purchasing land or beginning construction, as municipal opt-outs and site conditions vary across Connecticut.
