Basement Renovation FAQ

QUESTIONS 01

How Much Does the Renovation Cost?

The cost of a space renovation varies depending on the size of the space and the overall scope of the project. Adding features such as a bathroom, kitchenette, or a separate living suite will increase the total investment. Key factors that determine the budget include waterproofing, plumbing upgrades, and high-quality insulation.

QUESTIONS 02

Do you need a permit to finish the lower level?

In most cases, yes. A building permit is required if your your project involves electrical work, plumbing, structural changes, or the creation of a new legal living space. These permits ensure that the work complies with local building codes and safety standards.
