If you need more livable space for peace of mind,

let us build you a backyard home.

Invest in your backyard  to add more livable space for rental income, work, home school, man cave, she shed, guest house, home for your adult kid or parent.

Our advantage:

Fast track to more living space.

One site visit. Multiple backyard home options – from modular to traditionally built, and everything in between. Ordinance and zoning research. Budget estimate.

Permit support. Financing support. Budget & quality control.
Get up to three units on your single home lot with no zoning change.

Backyard home, officially called Accessory Dwelling Unit (ADU), also known as granny unit, secondary home, in-law unit, garden or backyard cottage, coach house, casita, pool house or even a bunkie, is the best, and fast, way to add more space to your house. It is not a shed, it will have eating, living, hygiene and sleeping facilities. Its permitting is streamlined. You can get it built in 6 months. It is flexible in use and can be rented out when not needed by the family. A detached unit does not trigger tax increase for the main house. It increases the home value. Investing in your backyard is literally a no regret move.

Building an Accessory Dwelling Unit (ADU) is the best way to add living space fast and, when built right, a great investment that increases your family wealth, as soon as construction is over.

Let us get started and build your ADU – Detached, Attached or Junior; Panelized, Modular or Custom. We have a plan for any shape and a crew for every kind.

We do the work on your behalf, so you don’t have to.

“Single application” to multiple builders

We are your construction broker. That means multiple estimates. Do not lock yourself out of options by signing with one builder (or his sales person) too soon – check all possible ADU options that will work on your property and select the best fit. Browse existing models or create new – in your backyard. See our growing ADU portfolio here.

I was glad to see that your content to homeowners was accurate and varied. It wasn’t a “sales pitch” like I’ve seen from others.

Accessory Dwelling Unit – what does it mean? A secondary home, on the same lot as the main house, that provides sleeping, eating and hygiene comforts. It can be detached, attached or converted from existing space.
