support@dwellingunits.comFrequently Asked Questions
How accurate are the calculator budgets?
Our calculator analyzes real-time product prices from major national retailers. However, actual material and delivery costs can fluctuate depending on your regional US location and local sales taxes. We always recommend adding a 10% to 15% contingency buffer to your budget plans to cover unexpected expenses such as site leveling, specialized tools, or delivery surcharges.
Do you provide local building contractors or assembly crews?
No, DwellingUnits is an informational, computational platform and planning utility. We supply the comprehensive DIY blueprints, R-value insulation calculations, and parts lists, but we do not direct building crews or provide manual structural contracting services. This allows us to remain fully unbiased and independent in our product recommendations.
Do I need a building permit for an under-120 sq. ft. structure?
In many jurisdictions across the United States, accessory structures that measure under 120 square feet do not require a building permit, provided they do not have permanent plumbing or electrical wiring. However, setbacks from property lines and height restrictions still apply. We highly recommend checking with your local county or municipal zoning department before laying your foundation.
