Rethink Starter Housing
ADUs, small lot, and infill development across Southern California and the Mountain West
Butterfly develops and builds starter home communities on infill sites with unrealized density potential. We focus on small format housing, using Accessory Dwelling Units (ADUs) and condominium law (AB 1033) to create missing middle housing inside existing neighborhoods.

Our Approach
Standard Plans
A library of plans pre-approved in multiple jurisdictions, adapted to each site rather than dropped onto it.
Design That Holds Up
Full kitchens, in-unit laundry, and finishes specified to rent or sell at the top of the submarket.
Parking, Privacy, Storage
Density that doesn't cost residents the things they'd have in a single-family home.
Entitlement to Delivery
Ministerial and by-right pathways, permitted and built on a defined schedule.
