// ADU Construction

A second home on your property

An accessory dwelling unit is an independent residential unit on the same lot as your home. Detached, attached, or converted — Avorino designs, permits, and builds it all.

Four ways to build

01

Detached ADU

Standalone unit in your backyard — maximum privacy and design flexibility. Popular for rental income or multigenerational living.

02

Attached ADU

Extension connected to your home with its own private entrance. Shares a wall for cost savings while maintaining complete independence.

03

Garage Conversion

Convert your existing garage into a fully permitted living space. The most affordable option — starting at $75K with the fastest turnaround.

04

Above-Garage ADU

Second story above your garage. Keeps parking, adds living space, and maximizes your lot without sacrificing yard area.

Starting at $75K for conversions, $250K+ for new builds
