Pre-Built Sheds Frequently Asked Questions
1. How do I start the process?
For both sheds and office trailers, begin with a site assessment to evaluate accessibility and placement options. Contact our team at (808)319-2847 or email sheds@hpmhawaii.com to discuss your specific needs. For sheds, we recommend finding an experienced professional to help with delivery and installation. For office trailers, our team can provide guidance on site preparation requirements.
2. What are the pricing options?
HPM Sheds range from $7,999-$11,999 plus tax, depending on size. Temporary Jobsite Office Trailers are available for $118,800 purchase or through our flexible rent-to-purchase option. Delivery and installation costs are additional for both products. All pricing is subject to change.
3. What's included with each product?
HPM Sheds include zincalume steel roofing, LP® SmartSide® siding, vinyl windows, and concrete blocks for foundation support. The Temporary Jobsite Office Trailers come with drywall walls/ceiling, LVP flooring, vinyl windows with protection grates, HVAC, LED lighting, data/power wiring, and plumbing connections.
4. What sizes are available?
HPM Sheds come in three sizes: 10'x8', 10'x12', and 10'x20'. We are unable to accommodate any modifications to the sheds. Our Temporary Jobsite Office Trailers feature a 12'x44' layout (528 sq. ft.) with two private offices, open bullpen area, and half bathroom.
5. How long does it take to receive my pre-built structure?
Shed manufacturing typically takes up to 2 weeks from production start. Office trailer availability varies based on current inventory. Contact our team for current lead times for both products.
6. Can I customize either product?
To ensure quality and timely delivery, we're unable to offer modifications or customizations to our standard designs for either sheds or office trailers at this time.
7. What about permits and regulations?
HPM Sheds are designed and built as a utility structure. Under the Hawaii County Building Code, utility structures measuring 200 sq. ft. do not require a permit. However, accessory structures, such as sheds, do need to follow zoning setback requirements per County Code Chapter 25, Article 5. Temporary Jobsite Office Trailer permit requirements vary by county and project location. For specific questions, please reach out to the County of Hawaii Building Division and Planning Departments.
If applicable, please refer to your neighborhood's HOA for any additional requirements.
8. What foundation options are available?
Sheds come with concrete blocks, but alternative foundation systems can be added at additional cost. Office trailers include 6 leveling jacks and require level ground for proper setup.
9. What material is the shed built out of?
Our utility sheds are built using HPM's Pre-engineered Wall Panels and rafter system, with pre-painted Custom Metal Roofing, and engineered LP® SmartSide® Siding panels. Interior finishings, plumbing, and electrical are not included. Shed exteriors are primed and ready to paint and have an unfinished interior with visible studs.
10. Are these products available on other islands?
HPM Shed flatpack kits are available for shipping statewide, with fully assembled units available on Hawaiʻi Island only. For Temporary Jobsite Office Trailer availability on specific islands, please contact our team.
11. How are deliveries handled?
Fully assembled sheds are available for pickup at HPM Building Supply in Keaʻau. Office trailers include a 2" ball trailer hitch for transport. For both products, we can connect you with qualified delivery professionals through our contractor network.
