Frequently asked questions

  • Do I need a building permit for a detached 3 car garage?

    Yes, in most cases, especially within city limits. Some jurisdictions and properties on farmland can be exempt. Be sure to verify for your chosen job site.

    Some key points to consider:

    First, ensure your 3-car garage plans comply with zoning ordinances, then apply for a building permit. Larger buildings or those with more occupants face stricter regulations.

    Submit certified plans: Building officials require third-party certified plans for the structure and foundation. A reputable manufacturer should provide these.

    Understand zoning: Determine if your site is zoned commercial or residential and understand specific requirements.

    Plan for permit processing: The permit application process can be lengthy.

    Prepare an official site plan: a licensed surveyor or structural engineer should design an official site plan necessary for the permit applications.

    Keep permits on-site: Once you have the necessary permits, keep them ready for any required inspections at the job site.

    Adhere to approved plans: inspectors will reference the certified blueprints throughout construction. If design changes occur, submit new certified plans and apply for new permits to avoid delays and fines.

  • What are my options for installation?

    When it comes to erecting your detached 3-car garage, you have three options.

    Do-it-yourself (DIY). We only advise going this route on smaller buildings (under 2,000 square feet) and if you have previous construction experience.

    Self-manage. With a self-managed project, you are responsible for hiring and managing the various sub-trades, including the concrete company for the foundation, the steel erectors to construct the kit, plumbers, electricians, etc.

    Hire a General Contractor (GC). For a completely hands-off option, you may want to consider hiring a GC who will manage the entire project on your behalf, from pulling permits and installation to the final inspection. Expect to pay 10-20% for the services of a GC.

  • Why are your buildings more expensive than other options I have seen online?

    Our suppliers sell only commercial-grade, pre-engineered metal buildings (PEMBs) engineered with solid steel I-beam framing.

    The majority of buildings you will have seen online are light-gauge tubular metal buildings. The price difference is due to tubular structures weighing less than half of a PEMB, which impacts the overall cost as steel is sold by weight. It’s a classic case of apples and oranges!

  • What financing options are available for detached 3 car garages?

    The simple answer is, "Sure you can." Here are the most common options for financing a new 3 car detached garage.

    Consider home improvement loans for smaller projects like garages or shops.

    Home Equity Line of Credit (HELOC) is more flexible and has competitive rates, but you must use your home as collateral.
    Construction loans are ideal for larger residential and commercial projects.

    Farm credit for agricultural and farm building projects is the final option.
