Subcontractors questions, answered by experts

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.

Depending on your structure, you may not need planning permission. Major excavation, anything that changes the external appearance of your home, or any construction that will affect your neighbors will need planning permission. However, no planning permission is required if you’re just converting an existing space into a root cellar.

A contract should outline the scope of work, timelines, costs, payment schedule, and materials used for clarity and protection.

On average, the cost to transform your garage into a workshop is about $2,000. The overall project cost depends on the type of workshop you want to build and its size. Regardless of the type of workshop, you’ll still need basic workshop spaces and equipment such as a workbench, cabinets, and space for storage and for working.

Most commercial projects take 3-7 days, including curing time, depending on size and weather conditions.
