Each option starts with a property review. Ownership, funding and fees are agreed for your property before anything is signed. There is no standard split, financing offer or purchase commitment, and not every lot can be divided or sold separately.
Washington's New Housing Laws
Recent state laws require many Washington cities to allow ADUs and more homes on residential lots. A property that could not add a home a few years ago may be able to now.

Frequently Asked Questions
Is my backyard suitable for another home?
It depends on your city's current rules and on the lot itself: size, shape, access, slope and utilities. A property review is how we find out.
How many homes could fit?
There's no general answer. State law sets minimums for cities; your city's code and your site decide what can actually be built.
Do I need to pay for the construction?
With Build & Own, yes. You fund the new home. In a partnership, funding is set by the agreement. In a sale, the buyer funds development.
Can I sell part of my property?
Sometimes. Condominium ownership, unit lot subdivision and lot division are different routes, and none is available everywhere. We check which, if any, applies.
Can I stay in my home during construction?
Often, but it depends on the work, access and safety. We plan that with you before construction starts.
What happens to my existing mortgage and property ownership?
Your lender and title may need to be involved. We identify what's needed early, and your own advisers confirm it.
How are partnership responsibilities and proceeds determined?
By a written agreement for that property, covering funding, guarantees, decision rights, cost risk and how results are shared. We don't use a standard split.
What does the first review include, and what is paid work?
The first conversation is free and without obligation. A full feasibility study and later services are quoted in writing for the scope you choose.
How long could the process take?
It varies with the city, the design and the permit path. We give you a realistic range once we know the property.
Can I keep the new home as a rental or for family use?
Yes, if that's the path you choose and local rules allow it. We can also help manage it as a rental.
