Serving Troy Michigan

Troy is home to 87,294 people on 33.45 square miles along I-75, with the Big Beaver Road business district and the Somerset Collection, more than 180 stores joined by a skywalk, at its center.

Its accessory building rules start early: a permit is required once a structure passes 36 square feet or 4 feet in height. Any carport you can park under crosses that line.

Custom Steel Buildings in Troy

You won’t find the word “carport” in Troy’s zoning ordinance. A detached carport is reviewed under Sec. 7.03 as an accessory building: rear yard only, one story or 14 feet, and a size formula tied to the area of your lot.

Steel suits a project that will be reviewed on paper. Our frames are engineer-certified, can be stamped by a licensed engineer when a permit calls for it, and are sized for the 25 psf of ground snow the code sets for Oakland County.

Frequently Asked Questions

How much does a metal building cost in Michigan?

Pricing depends on the size, steel gauge, roof style, and any add-ons like insulation, walk-in doors, or windows. Most projects range from a few thousand dollars for a basic carport to well over $20,000 for a fully enclosed, insulated workshop. We provide a full itemized quote before you commit to anything, so there are no surprises.

How long does metal building installation take?

Most standard carports and garages are installed within a few days to a week once materials arrive on site, depending on size and site preparation. Larger custom buildings or those requiring a poured foundation can take longer. We’ll give you a realistic timeline as part of your quote.

Do you install steel buildings in the winter?

Yes — Michigan winters don’t stop us. Steel buildings and pole barns can be installed year-round, though site conditions like snow and frozen ground may affect scheduling for foundation work. We’ll walk you through what to expect for your specific project and location.

What's the difference between a pole barn and a steel building?

A pole barn uses a post-frame construction method — large posts set into the ground or on piers support the roof — which is typically more cost-effective for large, open spans like agricultural storage or workshops. A steel building (or metal building) usually refers to a fully engineered, pre-fabricated steel frame system, often used for garages and commercial structures. Both can be fully enclosed, insulated, and customized — the right choice depends on your use case and budget, and we can help you decide.

What areas of Michigan do you serve?

We install across the entire state, from Southeast Michigan and West Michigan to Mid-Michigan, Northern Michigan, and the Upper Peninsula. Visit our Service Areas page to find your specific city or region.

Do I need a permit for a steel building in Michigan?

Permit requirements vary by township and county — some areas require a permit for any structure over a certain size, while others have different rules for open carports versus enclosed buildings. We help confirm exactly what’s required for your specific location before your project starts, and can guide you through the process.

Can I finance a steel building?

Yes. We offer flexible financing options so you can get your building now and pay over time, instead of paying the full cost upfront. Terms and approval depend on the size of your project — see our Financing page for details or ask your quote specialist.

Are your buildings engineer-certified?

Do you offer DIY metal building kits?

Yes — for customers who want to handle their own construction, we offer metal building kits with all the materials and hardware needed. We also offer fully installed options if you’d rather leave the labor to our crews. Either way, you get the same engineer-certified components.

Can a metal building be insulated?

Yes — insulation can be added during the original installation or as a retrofit later on. We offer spray foam and reflective insulation options, both of which help control temperature and reduce condensation inside the building year-round.
