Own a Ellery ADU Studio Franchise
Since 2015, Ellery ADU Studio has designed, permitted, and built more than 900 accessory dwelling units. Every one of those projects started with a written price and ended with a documented photo record. Now we’re expanding through independently owned and operated territories, and we’re looking for operators who understand that the ADU market isn’t a construction play. It’s a zoning, permitting, and documentation business with a build attached. Ten home-service brands operate under one standard: The Haven Standard. The ADU brand is the one you’re reading about now.
Why This Opportunity
Proven Brand With a Ten-Year Track Record
Ellery ADU Studio has been operating as a design-build studio since 2015, the year California’s ADU law fundamentally changed and permits became the real bottleneck. That timing matters. We built our systems around the actual problem: the drawings, the permit set, and the construction are one contract with one price, so neither the designer nor the builder can point at the other when something goes wrong. Our brand moat is simple: a written price before work starts, a documented photo record on every visit, and a 365-Day Done Right Promise that is put in writing, not spoken. Franchisees inherit that moat on day one.
Recurring Local Demand That Doesn’t Depend on New Construction Cycles
ADUs thrive in high-cost housing markets where homeowners bought between 2015 and 2025 and have equity but not square footage. That describes every metro core and affluent inner suburb in the country. Accessory dwelling units solve a zoning-enabled problem: the garage that isn’t parking cars, the backyard that isn’t being used, the grown child who can’t afford rent, the parent who needs to be nearby. These projects are not discretionary remodels. They’re income decisions, aging-in-place decisions, and housing decisions. Demand persists through rate cycles because the math for the homeowner stays compelling in expensive zip codes.
Marketing and Lead Engine Built on Published Pricing
Most contractors hide their pricing behind a phone call. Ellery ADU Studio doesn’t. Our no-hassle upfront pricing is a Haven Standard requirement: every project is quoted with a written price before any work begins, per Clause 1. The words “call for a quote” do not appear anywhere on our site. That changes how leads behave. Homeowners who research before they contact see a brand that names the price, documents the work, and answers the phone with a live person 24/7. Franchisees run their own local marketing, but they run it with a brand that converts on trust signals most competitors cannot offer: a Free Second Opinion on any written estimate, background-checked and uniformed crews, and a license number that appears on every page, verified rather than claimed.
Training and Support That Replaces Guesswork With Systems
The ADU projects that go wrong are almost always the ones where the designer and the builder each blame the other. Our one-contract design-build model eliminates that split. Franchisees learn our ADU Design & Permitting process, Garage Conversion ADU workflow, New Detached ADU standards, Junior ADU & Interior Conversion approach, and ADU Site Prep & Utilities coordination. They also learn prefab and modular fluency across Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie. Specifying and coordinating those systems inside a single contract is a skill most local builders don’t have. Our support team teaches it and backs it with documentation systems that turn every project into evidence.
Limited Territories Available
We are not opening unlimited territories. Each state has a defined number of protected markets, and when a territory is claimed, it’s off the board. That’s not urgency theater. That’s the structure: a franchisee’s value is tied to their protected local market, their trucks, their license, and their neighbors. Haven does not pretend to be from anywhere. The local business is the franchisee, and a protected territory is what makes that local identity worth building. If you’re considering an ADU franchise, we recommend requesting information sooner rather than later. Once your market is taken by another operator, it’s gone.
