Franchise Investment Overview
This page is a straight look at what it costs to open an Ellery ADU Studio location. The numbers below are ballpark ranges based on what we know ADU design-build operations require in 2026, not a legal offering document. Every market differs, every buildout differs, and the only numbers that matter are the ones you’ll receive in writing after we’ve walked through your territory together. What we can tell you now is that the ADU category is structured differently than most home-service franchises, because the revenue per project is high and the sales cycle is long. That changes the math on how much working capital you need before the first permit gets pulled.
Estimated Startup Investment
The table below reflects a startup range for an independently owned and operated Ellery ADU Studio location. We built these estimates around the reality of running a design-build operation: you need a professional space to meet clients, a licensed team to produce drawing sets, and enough cash to carry operations through the permitting queue. The franchise fee is a one-time payment. The rest is what it takes to open the doors and keep them open until signed contracts convert to progress payments.
| Item | Estimated Range |
|---|---|
| Franchise Fee | $45,000 - $65,000 |
| Design Studio Buildout & Equipment | $35,000 - $70,000 |
| Vehicles & Field Equipment | $25,000 - $55,000 |
| Initial Marketing & Launch | $20,000 - $40,000 |
| Working Capital (first 6 months) | $75,000 - $120,000 |
| Total Estimated Investment | $200,000 - $350,000 |
A few notes on these numbers. Working capital is the largest line item for a reason: ADU projects run on a permit-and-draw schedule, not a service call schedule. You’ll carry design costs, plan check fees, and build mobilization before your first progress payment lands. The marketing budget assumes a digital-first launch in a defined territory, including photography of completed local projects and a documented photo record system from day one. Equipment includes CAD workstations, a plotter, field tablets, and the vehicle wrap that puts your license number where clients can see it.
What’s Included
The franchise fee is not a list of promises. It’s the cost of entering a system that already runs the way Nadia Ellery has run the studio since 2015. Here’s what it covers:
- Brand license and territory rights for your defined market area, so you’re not bidding against another Ellery location three streets over.
- Initial training program covering the ADU Design & Permitting process, Garage Conversion ADU, New Detached ADU, Junior ADU & Interior Conversion, and ADU Site Prep & Utilities, including how to write a fixed-price contract that holds up in plan check.
- Launch marketing system with templates, local SEO architecture, and the photo-documentation workflow that becomes your client-facing proof system.
- The Haven Standard operations manual, including the written-quote process (Clause 1), the 365-Day Done Right Promise language, and the client communication cadence that eliminates the “where is my permit” phone call.
- Prefab and modular brand coordination training covering Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, so you can specify and coordinate these systems within the single-contract model.
- Ongoing support and systems access including drawing review, permit coordination templates, and the buying power on materials that keeps your bids competitive against local GCs.
Financing & Next Steps
Third-party financing for equipment and startup costs is commonly available through SBA-eligible lenders and specialty franchise finance companies, though Ellery ADU Studio does not provide financing directly. Most candidates bring a combination of liquid capital and an SBA loan or home-equity position, and the working capital requirement is designed to reflect what a real design-build operation needs to survive the first permit cycle. We’ll walk you through the standard lending landscape when we talk, including what lenders typically want to see from an ADU business model.
