ADU Specialist

Thinking about building an ADU or guest house on your property?

ACCESSORY DWELLING UNITS | IN-LAW UNITS | VACATION RENTALS | BACKYARD COTTAGE | GRANNY FLAT

Adding an Accessory Dwelling Unit, or also known as a Granny Flat, is the perfect way to have a dignified living space for your senior family member to be close to home, but also have their own living quarters to call their own.

Turn an empty space in to the perfect guest suit for friends and loved ones.

If you’re a Central Coast homeowner looking for a way to add a room to your home, whether it be for a family member, a vacation rental, or just a guest space for when friends come to visit, you’ve come to the right place. Our team at Frantz Construction can help you design and build the perfect Accessory Dwelling Unit (ADU) for your home. 

ADU’s, also called in-law units, granny flats, and backyard cottages, are independent living spaces that are autonomous from your main home or living area. They are very simple in design and footprint, typically ranging from 750 – 1200 square feet and they are often outfitted with ADA accessibility features for safe and self sufficient living. 

Frantz Construction is your Central Coast ADU specialist ready to turn an empty space into the ideal guest suit. From concept to completion, we will manage and execute every aspect of the process to create the perfect ADU for your family.

They put a lot of pride and care into the work they did. I’m very happy with the finished product.
