Why build an ADU?

ADU stands for Accessory Dwelling Unit. Also known as tiny home, granny flat, in-law unit, or garage apartment.

Make the most of your Accessory Dwelling Unit (ADU) by renting it out. This offers you a consistent stream of income from tenants. By doing so, you not only earn extra money but also step into the role of a landlord, making your property work harder for you. It's a smart way to capitalize on space you already own.

Rent out for profit

Leverage your ADU as a rental property, providing a lucrative source of steady income from tenants and becoming a landlord.

Maximize home value

Elevate your home's market value by adding an ADU, making your ADU property investment even more rewarding.

Take care of loved ones

Accommodate loved ones, like an elderly parent, in your ADU, ensuring their safety and comfort all while maintaining independence and privacy.

ADU Types

Different types of ADUs

Though backyard homes are typically the most familiar, ADU structures come in various types. The illustration below shows the four primary types of ADU structures.
ADUs can be built using a variety of construction methods, including pre-fabricated, modular, shed, container, panelized (in pieces), and stick-built. Each construction method has its own advantages and disadvantages in terms of cost, time, and customization.
Detached ADU
A Detached ADU is a standalone structure separate from the main home, typically located in the backyard. These units offer maximum privacy and flexibility for use as a rental, guesthouse, or home office.
Garage Conversion ADU
A Garage Conversion ADU transforms an existing garage into a livable unit. This is often the most cost-effective way to add an ADU without expanding the building footprint.
Addition / Attached ADU
An Attached ADU is built as an extension to the main house, sharing at least one wall. It can be added to the side, rear, or top of the existing home.
