Schedule a consultation with us, and let’s come up with a design plan that will achieve your goals and add value to your home.

    Is it worth it to build an ADU?

    Adding an accessory dwelling unit to your property in San Diego is undoubtedly worth it, and these are some of the top reasons why you shouldn’t wait any longer before you call your trusted local ADU contractor and schedule a consultation:

    • Increased property value: Building an ADU is one of the most efficient ways to boost the resale value of your home. So, if you’re looking for a house addition project that will provide you with a high ROI, building an accessory dwelling unit is the way to go.
    • Rental income: If you’re looking for an easy way to generate some additional income, you can always turn your ADU into a vacation rental. This option is much better than renting out a spare room on Airbnb because both you and your guests will have complete privacy.
    • Housing for adult children: If your child is almost an adult and on their way to becoming fully independent, then an ADU can be a great temporary housing solution for them. They will still be close to you but have the privacy they need.
    • Functional office space: If you work from home, why not turn your ADU into an office? You’ll have your peace and quiet and a lot of space to meet with your clients.

    As one of the leading ADU builders in the San Diego area, Lars Room Additions is your go-to business if you’re considering building an ADU on your property.
