Frequently asked questions
-
Do I need a building permit?
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 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 form, structure and foundation. A reputable manufacturer should provide these.
- Understand zoning: determine if your site is zoned commercial or residential and understand specific requirements and building prices.
- 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 at the job site ready for any required inspections.
- Adhere to approved plans: inspectors will reference the certified blueprints throughout establishment. 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 building, 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 establishment experience.
- Self-manage. With a self-managed outline, 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 Head Contractor (GC). For a completely hands-off option, you may want to consider hiring a GC who will manage the entire design 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-steel gauge tubular metal structure. The difference in building pricing is due to steel tubular structures weighing less than half of a PEMB, impacting the overall cost and starting price as steel is sold by weight. It’s a classic case of apples n’ oranges!
-
What financing options are available for metal buildings?
Here are the most common options for financing a new building.
- Consider home improvement loans for smaller projects like workshop garage, detached garage or pottery shops.
- Home Equity Line of Credit (HELOC) is more flexible and has competitive and rates, but you must use your home as collateral.
- Establishment loans are ideal for larger residential and commercial plans.
- Farm credit for agricultural and farm building projects is the final option.
-
Why must doors and windows be 2' from corners and the roof eave?
Maintaining a 2-foot distance from the corners and the eave of a steel building's roofline ensures structural integrity, safety, compliance with building codes, and practical build considerations.
- Support and stability: corners provide critical support, and keeping framed openings away from corners guarantees stability.
- Load distribution: a two-foot distance also ensures even load distribution, preventing structural issues.
- Foundation stability: this prevents compromising the foundation and framing during high wind or snow loading.
- Ease of build: Simplifies the installation of door and windows view
- Insulation and energy efficiency: the corner and eave areas are critical for the building's thermal envelope. Keeping openings away from these areas allows continuous insulation in these high-heat-loss areas. It also prevents thermal bridging at structural connections, improving the building's overall energy performance.
- Weather protection: placing openings away from corners helps prevent water from seeping in and allows for sound flashing installation around openings, reducing exposure to wind-driven rain in vulnerable corner/eave areas.
- Clearance for framing: a minimum 2-foot clearance allows room to frame and support the door or window opening correctly. This space is needed to fit wall girts between the corner column and door/window jamb.
Our manufacturers often recommend adding 8-10 inches to the minimum 2-foot distance for buildings with bypass sidewalls to account for the bypass girt depth.
