Franchise Investment Overview
We believe in putting numbers on paper before asking for a commitment. That’s why this page gives you a straight, ballpark look at what a Fielding ADU Builders franchise costs to open. These are marketing estimates, not a legal offering. They exist so you can decide whether this is worth a serious conversation. ADU construction is a trade with real trucks, real tools, and real payroll. If you have run a construction business or managed field crews, the ranges below will make sense to you fast.
Estimated Startup Investment

The table below reflects what we have seen across markets we have studied. Ranges vary by city, lot sizes, and whether you start with one crew or two. The numbers are ballpark figures meant to frame the conversation, not a final price sheet.
| Investment Category | Estimated Range |
|---|---|
| Franchise Fee | $55,000 – $85,000 |
| Equipment & Vehicles | $40,000 – $90,000 |
| Initial Marketing & Launch | $25,000 – $50,000 |
| Working Capital (first 6 months) | $80,000 – $150,000 |
| Total Estimated Investment | $200,000 – $375,000 |
Working capital is the biggest line for a reason. An ADU build runs months from permit to final inspection. You’re carrying labor, materials, and site costs before the final invoice clears. If you’ve built additions before, you know what that float looks like. If you haven’t, the training covers it, but you should still plan for it in your bank account, not just on paper.
What’s Included
The franchise fee buys you a running start, not a logo and a handshake. Here’s what comes with it:
- Brand license and territory. You operate as Fielding ADU Builders in a defined area. You are an independent local business working to The Garrison Standard, same as every location in the family.
- Training for you and your lead field supervisor. We cover estimating, permitting, scheduling, crew management, and what happens when a job goes sideways. Which it will, because construction.
- Launch marketing playbook. Local website, service-area targeting, the written-price offer, and the 365-Day Done Right Promise positioned in your market from day one.
- Operating systems. Written price templates, guarantee language, job-scheduling tools, and the reporting that keeps a construction business honest.
- Prefab and modular platform fluency. We train your team on Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. That means you can bid conventional builds or factory-built units depending on the lot and the budget.
- Brand standards and ongoing support. Background-checked, uniformed crew expectations. Live-person phone coverage. The Garrison Code, in writing, from your first project onward.
Financing & Next Steps

Third-party financing options exist for equipment, vehicles, and startup working capital. Banks and SBA lenders see ADU construction as a growing category, and having a franchised brand with written pricing and a written guarantee helps in those conversations. We do not provide financing directly, and we never guarantee a lender will approve you. What we do is give you clean numbers and a clear picture of what the first year looks like.
The process from here is simple. You call, we talk, and if it looks like a fit we send you the formal documents. Those documents contain the official figures for your market, the full agreement terms, and everything a serious investor needs to make a decision. Nothing on this page replaces those documents.
If you want the real numbers for your territory, call (361) 315-4177 or request the information kit below. Someone picks up. It is not a voicemail tree.

What the Franchise Fee Does Not Buy
We are direct about this because it matters. The fee does not buy guaranteed revenue. It does not buy a book of customers. It buys the system, the training, the brand, and the standard. The work of building the business is yours. What we give you is a method that has held up since 2006 under the Garrison Partners name. The Garrison Code is not a slogan on a wall. It is five commitments: show up inside the window we gave, price in writing before any work starts, do it by the book the first time, leave the site clean and squared away, and stand behind the work for a full year. If a franchisee cannot live by those, this is the wrong business for them.
Why ADUs and Additions, Specifically

ADU construction is not a fad. Municipalities across the country are rewriting zoning to allow accessory dwelling units on single-family lots. Homeowners are looking for rental income, space for aging parents, or room for adult kids who cannot afford a house. The demand is there. The supply of disciplined, permit-correct, written-price builders is thin. Homeowners are worn out by no-shows and prices that move at the door. A franchise that shows up on time, prices in writing, and guarantees the work has a genuine edge. That edge is what you are buying.
Fielding is an old building-trade surname. It sounds like a firm that has framed a few homes. That was the point when the name was chosen. We wanted a name that sounded like it belonged on a trailer parked outside a job site, not a tech startup.
Who Should Inquire
This opportunity fits people who have run crews, managed construction schedules, or owned a trade business. It also fits investors with the discipline to hire a strong operations lead and hold them to the standard. What it does not fit is someone looking for passive income. Building is active work. Permits move slowly in Los Angeles, and they move slowly in most other metros too. Reed Calloway, our owner, has a dry observation or two about LA permit timelines, but only because it is accurate. If you want to build square, permitted, and finished on schedule, call (361) 315-4177. We’ll talk real numbers.
