This post is part of AGI’s 7 Lies series. For the full breakdown, read 7 Lies About Gunsmithing That the Internet Tells You.
If you’ve spent any time researching how to open a gunsmith repair shop, you’ve probably run into the same assumption on forums, Reddit threads, and YouTube comment sections. You’ll need a real commercial shop: a storefront, a big open floor plan, a lease, and a business address in town before anyone takes you seriously.
It sounds like common sense. It’s also wrong.
It’s easy to see where the idea comes from. It usually shows up right behind Lie #2. Once people believe gunsmithing takes a mill, a big lathe, and tens of thousands in tools, they naturally assume it takes a big room to hold it all. Most businesses people deal with every day also work out of a commercial address, so a home-based firearms business can sound unofficial, or even illegal.
Commercial shops aren’t bad. Some gunsmiths use one, and some cities require one. The lie is that a big, expensive location is a prerequisite, that you have to sign a lease before you’re allowed to start. That’s the part that stops people before they’ve measured a single foot of bench space or made one phone call to their zoning office.
This is Internet Gunsmithing Lie #3: “You need a BIG Shop or an Expensive Commercial Location.” It’s the third of seven lies the internet keeps repeating about this trade; you can see the full list in 7 Lies About Gunsmithing That the Internet Tells You. It’s worth taking apart carefully, because it’s the lie that turns a realistic plan into an intimidating one.
The Gunsmith Who Started With a Hand-Lettered Sign
One AGI graduate finished his training, got his FFL, and opened with nothing more than a small rented shop and a hand-lettered “gun repair” sign by the road. He had no existing customer base and no advertising budget to speak of. In less than a year, he was backlogged with hundreds of firearms and roughly three months of work.
Look at what’s missing from that story. There was no storefront on Main Street, no big floor plan, no expensive buildout. His space was about as modest as a gunsmith repair shop gets, and it didn’t hold him back for a minute.
That distinction is the whole story. The shop wasn’t what brought in hundreds of firearms. His training was, along with the reputation it let him build one correct repair at a time. The building was just where the work happened. What customers were really paying for was someone who understood how their firearm was designed to function and how to fix it when it didn’t.
Think about it this way. Nobody chooses a watchmaker by the size of his shop. A watchmaker works at a small bench under good light, and customers care only about whether the watch comes back running. Gunsmithing works the same way. A customer handing over a firearm wants it fixed correctly. Square footage never enters the decision.
What the Rules Actually Require
To be fair to the commercial-location idea, it’s worth looking at what the law requires of a gunsmith repair shop, because that’s where most of the nervousness comes from.
Under federal law, gunsmithing is a licensed activity. Federal law defines a “dealer” to include anyone engaged in the business of repairing firearms or fitting special barrels, stocks, or trigger mechanisms. In practice, that means a standard dealer’s FFL, not a special shop license. The federal rules also specifically account for the way gunsmiths work. ATF Ruling 73-13 holds that a gunsmith who works solely in that line of business is not required to keep regular business hours. If the business is run from a private home, a separate portion is designated as the business premises, which needs to be accessible only to the gunsmith’s clientele rather than open to the general public.
Where the location question really gets decided is locally. On ATF Form 7, the application for a Federal Firearms License, applicants certify that their business is not prohibited by state or local law at the premises listed, including zoning ordinances. The form also tells applicants to contact their local zoning department before submitting the application. That’s why the first call to make isn’t to a commercial realtor. It’s to your local zoning office.
AGI walks students through this process during enrollment, and you can see the details on AGI’s FFL and gunsmithing shop FAQ page. For the full licensing walkthrough, see AGI’s guide on how to get an FFL license (link once live).
Some cities do require a commercial location. If yours does, it isn’t the setback it sounds like. You generally need only about 100 to 200 square feet to get started: a small office, a converted room, or a modest portion of a larger building. There are also more options than people expect. Some new gunsmiths sublet space inside an existing gun shop, which can bring a built-in customer base and referral relationships from day one. Others find room in an automotive shop, a machine shop, or another light industrial building, because gunsmithing is light bench work that fits naturally alongside those businesses.
The Real Bottleneck: Reputation, Not Square Footage
The part that rarely gets talked about is that a bigger space can actually work against you.
The first problem is efficiency. The more spread out your workspace, the more time you spend walking between your bench, your tools, and your storage instead of working on the firearm in front of you. In a trade where reputation depends partly on turnaround time, slower work is a real cost, not just an inconvenience.
The second problem is overhead. A large commercial lease is a fixed monthly cost you owe whether or not work is coming in yet. It’s a bet placed before you know how quickly your reputation will build. A home-based setup or a small sublet carries a fraction of that fixed cost. More of your early income can then go toward better equipment, marketing, or a financial cushion, instead of rent on square footage you’re not yet using.
What actually fills a gunsmith’s bench is trust. Nobody gets backlogged because their shop was impressively large. They get backlogged because customers trust the quality of their repairs, and customers in this trade talk to each other. A modest home shop with a reputation for careful, correct work will out-earn a large, expensively outfitted shop with a reputation for mediocre repairs. That reputation comes from understanding Design, Function, and Repair (D, F, & R), not from the size of the building.
How Much Space Does Gunsmithing Actually Take?
Here’s the detail that quietly dismantles this myth: most firearms just aren’t that big. Even a long-barreled shotgun, one of the longest common firearms you’ll work on, runs roughly 4 feet overall. Handguns, most rifles, and the vast majority of repair jobs are considerably smaller.
Picture the physical footprint of a typical job. A firearm is laid out on a bench and disassembled into its parts, surrounded by the hand tools and rotary tool covered in Lie #2. Even with a vise, a parts tray, and room to move your hands freely, that fits comfortably on a bench, not a sprawling floor plan.
Gene Kelly’s own guideline is about 8 to 10 feet of bench space, and AGI’s FAQ puts the overall footprint at roughly a 10-by-20-foot area. More space is nice if you have it, but it isn’t a requirement to get started.
So What Does a Starter Gunsmith Repair Shop Actually Look Like?
If a home gunsmithing shop still sounds like a compromise, here’s what one looks like in practice:
A spare room, a garage, or a shed. This is the realistic starting point for most people figuring out where to start a gunsmithing shop. It’s a legitimate way working gunsmiths operate, and plenty of established gunsmiths never move beyond it, because it keeps working.
About 8 to 10 feet of bench space. That’s enough for disassembly, repair, and reassembly on nearly any firearm that comes through the door.
Good lighting and secure storage. You need to see small parts clearly, and firearms in progress need to be stored securely.
The tool setup from Lie #2. Hand tools, a Foredom-style rotary tool, and the few additions that come later as jobs demand them.
No storefront trappings. There’s no requirement for a separate entrance, a waiting room, or a retail counter. You can add those later if your business model calls for them.
Getting Started: What the Process Actually Looks Like
If you’re weighing where to start a gunsmithing shop, here’s the order that makes sense for most people:
- Check your local zoning rules first. Confirm whether your city or county allows home-based firearms business activity. A call to your local zoning office, or the sample process AGI provides during enrollment, usually answers this faster than people expect.
- If you’re renting, talk to your landlord early. Your home will be the licensed premises on your FFL application, so it’s better to have that conversation upfront than to be caught off guard later.
- Measure the space you already have. A spare room, a garage corner, or part of a shed with 8 to 10 feet of usable bench space is enough for most gunsmithing work.
- If home-based isn’t an option, look small. About 100 to 200 square feet of commercial space covers what you need, and a sublet inside a gun shop, automotive shop, or light industrial building can work too.
- Build your setup around the work. Choose your bench, lighting, and storage based on the tools and workflow from Lie #2, not on filling a bigger space than you need.
Notice that “lease a large commercial storefront” doesn’t appear anywhere on that list. If a zoning answer or a landlord conversation doesn’t go your way, that’s a solvable logistics problem, not a dead end. A different property, a sublet, or a small commercial space usually gets you to “yes” with an extra step or two.
Common Questions About Starting a Gunsmith Repair Shop
How much space do you actually need to start a gunsmith repair shop?
About 8 to 10 feet of bench space covers most repair work, since even long-barreled shotguns run only about 4 feet overall. AGI puts the overall footprint at roughly 10 by 20 feet, which a spare room, garage, or shed can usually provide.
Can you legally run a gunsmithing business from home?
In many areas, yes. Federally, gunsmithing is done under a dealer’s FFL, and the ATF does not require a gunsmith’s premises to be open to the public or to keep regular business hours. The deciding factor is local: your city or county zoning has to allow firearms business activity at your home address, so check with your local zoning office before you commit.
What if your city requires a commercial location for gunsmithing?
You generally need only about 100 to 200 square feet, which fits a small office, a converted room, or part of a larger building. Subletting space inside an existing gun shop, or finding room in an automotive or light industrial building, are both realistic options.
Do you need a storefront to be taken seriously as a gunsmith?
No. Customers care whether their firearm gets fixed correctly, not whether the repair happened at a commercial address or a home-based shop. Reputation, word of mouth, and consistent quality build a gunsmithing business far more than square footage. A bigger, more spread-out shop can even slow you down.
The Bottom Line
The idea that you need a big shop or an expensive commercial location isn’t really about space at all. It’s about whether the person at the bench can fix what comes across it. A storefront doesn’t guarantee that. An 8-to-10-foot bench in a converted garage, run by someone who understands Design, Function, and Repair, will outperform a sprawling, expensively outfitted shop run by someone who’s guessing.
The graduate with the hand-lettered sign didn’t get a three month backlog of customers wanting him to work on their guns because of his building. He got there because his customers trusted his work, and that trust came from his training. That knowledge is what AGI has spent over 30 years teaching people from home.
If you’ve been holding back because you assumed you’d need a lease and a storefront before you could start, make two calls first: one to your zoning office, and one to a tape measure. The question was never “can I afford a commercial shop?” It was always “do I have the skill to fill whatever bench I work at?” Once you answer that honestly, the rest of the decision tends to take care of itself.
