Answering Your Common ADU Questions

Frequently Asked Questions

ADUs are typically detached from the main house as stand-alone structures but can also be attached through options like a simple open-air breezeway or a seamless addition. ADUs are often used to house family members, serve as pool houses, or provide guest quarters, making them a popular way to increase a property’s usable space.

An ADU is built as a standalone house on its own lot, offering the freedom and flexibility to create your ideal living space. Unlike other compact living solutions, an ADU home provides a fully independent dwelling that allows for privacy and a true sense of ownership. With the ability to customize its design and layout, an ADU on its own lot can be tailored to fit your unique lifestyle while adding value to your property.

In many municipalities, properties zoned as single-family or multi-family can accommodate an ADU, provided there is sufficient space. While the most common placement is in the backyard, ADUs can also be located in the side yard or even in front of the main house, as long as setbacks, local regulations, and easements are met. Additionally, ADU have the flexibility to be built on their own lots as standalone houses, offering a completely independent living solution.

Our Acorn ADU homes come fully finished, featuring a full kitchen, bathroom, living space, and optional bedrooms to suit your needs. Each home is built with quality materials and craftsmanship, offering a range of standard features, including:

  • LP siding (board & batten/LAP)
  • Lifetime Dimensional Composition Shingles
  • Milgard white windows and French doors (6′)
  • Luxury Vinyl flooring (Urban Floor)
  • Shaker cabinets
  • Butcher block countertops
  • Subway tile backsplash
  • 3 options for fixtures
  • Fiberglass shower
  • Stainless steel appliances
  • Stackable washer/dryer
  • Interior and exterior paint
  • Can lights
  • Decor plugs and switches
  • 125 amp panel
  • Water heater / Rinnai V65E (Gas)
  • Mini Split unit

Plus, we offer dozens of upgrades to customize your ADU and make it uniquely yours!

Because our ADU homes are stick-built on-site, we offer extensive options to customize our base models or even create a completely custom-built ADU home from scratch. From floor plans and room sizes to kitchen fixtures and design details, we’ll help you craft the perfect space you’ve always imagined.

Some of the key elements you can customize include:

  • External color and finish materials (including options to match your primary home)
  • Internal finishes from floors to tile to countertops to appliances and more!
  • Internal wall colors
  • Shower features — metal shower or porcelain showers, glass doors, and more
  • Kitchen features — sink styles, countertop materials, cabinet colors, and beyond

And that’s just the beginning—nearly every aspect of your new ADU home can be tailored to your vision. Have questions about customizations? Reach out today to speak with one of our experts!
