Explore Studio ADU Floor Plans

A studio ADU is the most efficient way to add a separate, self-contained space to your property. It is the lowest-cost build Hive offers and the easiest to fit on a tight or coastal lot, while still giving you a full kitchen, a private bath, and an open living and sleeping area under one roof.

Every studio is site-built on your lot from foundation to final inspection, designed around your property’s setbacks, lot coverage, and site conditions. Turnkey pricing starts at $172,328 and covers design, permitting, and construction under a single contract, with no hidden allowances. Browse the layouts below, then start with the one closest to what you need; we tailor it from there.

Start Small, Change Anything

A studio is a starting point, not a fixed plan. Adjust the layout, the finishes, or the footprint, or have us design a fully custom studio from the ground up. Either way, it is built around your lot and exactly how you will use the space.

NOT PREFAB, SITE-BUILT

Small Footprint, Real Construction

A studio is compact, but it is built like any house: poured on its own foundation, framed and finished in place on your property. The result is a permanent, code-built structure that adds to your home and lasts, not a shed or a factory box.

A small build, done to full-house standards.

WHY A STUDIO ADU

The Simplest Way to Add Space

A studio is the simplest, most affordable way to get onto your property’s long-term plan. With the smallest footprint Hive builds, it fits narrow side yards, tight lots, and coastal parcels where setbacks rule out anything larger, and it works as a home office, guest space, or room for a single adult.

A small space that does a lot.

Where a Studio ADU Fits Best

Small-Lot Friendly

The most compact-footprint Hive builds and the most forgiving on a difficult lot. Studios fit into narrow side yards, shallow rear setbacks, and tight infill or coastal parcels where a larger unit would exceed lot coverage limits. Every layout is adjusted to your property rather than forced onto it.

What Your Investment Covers

One contract covers design, engineering, permitting, site work, and construction through final inspection. Pricing is real and itemized, with no hidden allowances, and a studio’s simpler structure keeps it the lowest-cost build we offer. Where a site needs a major utility upgrade or extensive grading, it is scoped up front.

Ways to Use It

A home office for remote work, a private guest suite, a detached room for a single adult or college student, or caretaker’s quarters. A studio adds real, self-contained space, with its own entrance, kitchen, and bath, without the cost or footprint of a full second home.

Permits, Handled

Hive manages permitting in Santa Barbara and Ventura County and builds to the current state ADU law and local code, including coastal-zone, fire, and septic requirements. A studio’s lower structural complexity often moves through plan check more smoothly, and we handle the process for you end-to-end.
