2 Bedroom ADU Floor Plans

2 Bedroom ADU Floor Plans (750–1,000 Sq Ft)

The two-bedroom layouts we build in Orange County — for families, roommates and maximum rental value.

The short version

A 2 bedroom ADU typically runs 750–1,000 sq ft — two real bedrooms, a full bath, and a shared living-kitchen space. It’s the layout for a small family, roommates who split rent, or multigenerational living with space to breathe. We build two proven two-bedroom plans — The Tustin (750 sq ft) and The Newport (1,000 sq ft) — both customizable to your lot.

Every plan links to its full page with the 3D layout, specs and what’s included. Browse all sizes on the ADU floor plans hub, or compare 1 bedroom ADU floor plans.

Who a 2-bedroom suits

Small families, roommate pairs, or parents plus a grandchild — and landlords targeting the top of the rent band: two bedrooms consistently out-rent one-bedroom units in every OC city, and roommate demand keeps vacancy low.

What it costs

At the published 2026 rates — $270–$380/sq ft custom detached — a 750 sq ft two-bedroom typically lands around $205K–$285K and a 1,000 sq ft build around $270K–$380K. Run your size in the cost calculator.

The lot question

A 750–1,000 sq ft footprint needs genuine yard room after 4-ft setbacks. Deep postwar lots handle it comfortably; tighter lots sometimes do better with a two-story or above-garage layout that stacks the same bedrooms on half the footprint.

Quick answers

How big is a 2 bedroom ADU?
Typically 750-1,000 sq ft. California entitles qualifying lots to a detached ADU up to 1,200 sq ft, and state law protects at least 1,000 sq ft for ADUs with more than one bedroom — so a true two-bedroom is achievable in every OC city.
How much does a 2 bedroom ADU cost to build?
At 2026 Orange County rates ($270-$380/sq ft custom detached), a 750 sq ft two-bedroom typically runs $205K-$285K and a 1,000 sq ft build $270K-$380K, before site-specific factors. The on-page calculator on our cost guide gives a range for any size.
Does a 2 bedroom ADU rent for more?
Yes — two-bedroom units sit at the top of each city’s band (up to $3,200 in Irvine, $4,000 in Newport Beach) and attract families and roommate pairs, which keeps vacancy low.
Can a 2 bedroom ADU fit on a small lot?
Sometimes — and when the footprint doesn’t fit, stacking does: an attached two-story or above-garage ADU can deliver two bedrooms on roughly half the ground area, up to 25 feet by right.
