A three-bedroom ADU is a full home, not an accessory space. With three private bedrooms, two full baths, and proper living and kitchen areas, it gives a whole household room to live without compromise, and it is the largest, most complete build Hive offers.
Every three-bedroom is site-built on your lot, from the foundation to the final inspection, designed around your property and how your family will use it. Turnkey pricing starts at $457,628 and covers design, permitting, and construction under one contract, with no hidden allowances. Start with the layout below, then we tailor it to your household from there.
Model E-1188
A full home should fit the family. Reconfigure the bedrooms, open up the living space, adjust the baths, or have us design a fully custom three-bedroom from the ground up. The layout here is a starting point for your home, not a fixed plan.
A FULL-SIZE RESIDENCE
A three-bedroom is a full house in every way, poured on its own foundation, framed and finished in place on your property to California code. Three bedrooms, two baths, full plumbing, and real living space, a permanent residence that stands on its own and adds lasting value to the property you already own.
The size of a real house, because it is one.
Room for Every Generation
A three-bedroom home is the home families build when everyone needs to be together and still have their own space. Grown parents, children, and grandparents can share one property, each with private rooms and a full home around them, close enough for daily life and independent enough for everyone’s sanity. As the family changes, the home changes with it, without anyone having to leave.
One property, room for everyone in it.
SANTA BARBARA & VENTURA COUNTY
Three private bedrooms, two full baths, and full living and kitchen space, the layout a whole household needs, not a scaled-down version of one. Everyone gets their own room, and the home lives like a primary residence. The plan is fit to your lot rather than squeezed onto it.
One contract covers design, engineering, permitting, site work, and construction through final inspection, with real, itemized pricing and no hidden allowances. As the largest build in the lineup, a three-bedroom carries more square footage, more rooms, and more finish work, which is where the investment goes.
The home families build to keep parents, children, and grandparents on one property without anyone giving up privacy. Each generation gets private bedrooms and a full home around them, close for daily life yet independent day-to-day. It also serves a large household that simply needs the room.
Hive manages permitting in Santa Barbara and Ventura County and builds in compliance with current state ADU law and local codes, including coastal-zone, fire, and septic requirements. A full-size home offers the most structural and utility details of any ADU, and we manage all of them for you.
