Butterfly Dwellings, Inc.

Butterfly is a Southern California–based designer-builder specializing in custom accessory dwelling units (ADUs) and small‑format housing. We streamline construction timelines with a library of pre‑designed plans that are then customized to each specific property and the owner’s use case. Our team manages the full process—from architecture and engineering through permitting and construction—ensuring property owners predictable execution, high‑quality results, and a simplified process.

Our Los Angeles ADU Standard Plans include five of our most popular models that balance practicality with character. Each plan includes a full kitchen, in-unit laundry, and ample storage.

The Mesa Guesthouse is a 1-story, 749 sq. ft., one-bed, one-bath ADU that includes a full kitchen, a laundry room, and an owner’s suite. The floor plans include optional bi-folds in the living room and two entry point configurations, making the unit suitable to a wide variety of uses.
