Who’s Your DADU

Options for Building a DADU

Customizable Floor Plans, Pre Approved and Prefab Kit Units we build them all! If you love a pre approved design we can help make alterations to fit your aesthetic & our architects can help you design your Dream DADU.

Option 1: Prefab DADUs:

Factory-built units delivered to the site mostly complete; faster and often more cost-effective.

Option 2: Pre-Approved DADUs

Plans already reviewed and approved by the city for faster permitting; a middle ground in cost, speed, and customization.

Option 3: Custom-Built DADUs

Designed and constructed from scratch to fit specific site needs and homeowner preferences; most flexible but often pricier and slower.

Considering Your DADU Options

After you have an idea how you want your DADU to look you have to determine what type of Construction will best meet your needs.

There are several paths you can take when designing and building your DADU—whether you prefer a ready-made prefab unit, a fully custom design, or a streamlined pre-approved plan. If you’re not a designer, don’t worry—we’ll help you navigate your options and find the best fit for your property, budget, and long-term goals.

A 4th Option is an ADU

The main difference between an ADU and a DADU is that an ADU is attached to the primary home, while a DADU is a separate structure. Homeowners often choose an ADU when they have unused space like a basement, attic, or garage that can be converted into living quarters. It’s also a great option for those who want to expand their existing floor plan—adding a new section to the home for guests, aging parents, or rental income—while keeping everything under one roof for convenience and accessibility.
