What's included

Faster than building. Cheaper than buying.

01
Expandable on site

Arrives folded for transport. Opens to nearly double the closed footprint in a single day. No on-site construction — just unfold, connect, occupy.

02
ADU-code compliant

Engineered to the ADU regulations of California, Oregon, Washington, and other ADU-friendly markets. Capsul handles the certification, not your contractor.

03
Add value, fast

75–120 days from order to keys. Typical lot-value uplift exceeds installation cost in most US ADU markets — pays for itself before you let it.

Who it's for

Six ways an ADU pays back.

01
Long-let rental income

Add a permitted second dwelling to your existing lot. Generate rent without subdividing.

02
Short-let / Airbnb

In ADU-permissive markets, a Capsul ADU pays back faster than the original house in many cases. Fixed-price means yield is predictable from day one.

03
Multi-generational housing

Independent living for parents, in-laws, or adult children — on your land, not in your house.

04
Home office / studio

A separate workplace on your property. Tax-deductible in many jurisdictions for self-employed buyers.

05
Guest accommodation

Premium guest house for visiting family, clients, or rented privately during peak season.

06
Backyard granny flat

In Australia, the granny-flat regulation framework makes Capsul ADUs especially fast to permit — typically council-approved in weeks, not months.
