How Much Does It Cost to Finish a Basement?

Apr 16, 2025

Renovating your basement is one of the most valuable investments you can make in your property. If you want to create more living space, build a rented suite, or install a home theatre, the basement enhances the value of both comfort and property. However, the usual question homeowners ask is: “How much does it cost to finish a basement?”

This guide will explore the basement renovation cost and explain what factors have an impact on the renovation costs for the basement, which helps you make an knowledge decision on your housing improvement project.

Understand the Average Basement Renovation Cost

In Ottawa, the cost of finishing a basement is usually between $30 and $80 per square foot. This extensive price depends on many elements, including design complexity, materials, labor, and upgrades such as a bathroom or kitchen.

Basement Type Cost per Sq. Ft. Total Estimated Cost (for 1,000 sq. ft.)
Basic Finish $30–$45 $30,000–$45,000
Mid-Range $50–$70 $50,000–$70,000
High-End $70–$100+ $70,000–$100,000+

 

Factors that Cause Basement Renovation Costs

1. Size and Design of the Basement

The square in your basement is the first point for estimating costs. A large basement means more drywall, floors, light fixtures, and labor. A simple open space will be given a very low value with more than one room or special functions, such as a cooking house or laundry room.

2. Labor and Materials

Labor often represents 30-50% of the basement’s maintenance project cost. Skilled labor is crucial for framing, electrical installation, drywall installation, plumbing, and flooring. On the other hand, the material may vary depending on your taste and budget.

Popular options include:

  • Laminate or vinyl floor
  • Drywall vs soundproofed boards
  • Pot lights or track lighting
  • Customized cabinets and countertops

3. Permits and Building Code

All basement renovations should follow the local building code in Ottawa. This includes the bedroom, fire-rated materials, and the correct outlet windows for adequate ventilation. Permissions can spend $200 to $2000 anywhere based on the scope of your project. It is necessary to include it in the budget.

At On Points Renovations, we manage all the necessary permits and ensure complete compliance with local building standards.

Major Features and Impact on Costs

Below is a deeper look at the features that significantly affect the renovation costs in the basement:

Drywall Installation

A significant step to eliminate the basement, and the drywall installation usually costs between $2- $3 per square foot, such as materials and labor.

Add a Bathroom

Planning to add a bathroom? Expect to use anywhere from $ 8,000 to $ 15,000 for plumbing, waterproofing, furnishing, and tiling. This is one of the most expensive features, but it provides great value and comfort.

Electrical Work

Installing new outlets, light fixtures, or wiring for a home theatre setup will increase your cost. Basic electric work runs between $1,500 to $5,000, depending on your layout and power needs.

Cost of Painting

Painting is often the final touch. The cost of painting a basement depends on the scale and wall situation, starting from $1.50–$3.50 per square foot.

Flooring

Options such as:

  • Laminate flooring: $2–$5 per sq. Ft.
  • Engineered hardwood: $5–$10 per sq. Ft.
  • Luxury vinyl: $4–$7 per sq. Feet.

Choose based on your budget and design preferences. Laminate is a popular, affordable option that holds up properly in basement environments.

Optional Upgrades (And What They Cost)

Upgrade Estimated Cost
Heated Floors $3,000–$7,000
Soundproofing $1,000–$3,000
Egress Windows $2,000–$5,000
Kitchenette $8,000–$20,000
Home Theatre $5,000–$15,000
Laundry Room $4,000–$8,000
Built-in Storage $2,000–$6,000

These additions can enhance your basement’s functionality, but also raise the total cost.

Hidden or Additional Costs

A correct rule of thumb is to set aside 10–15% of your overall budget for unexpected expenses.

Always plan for additional charges during renovation:

  • Mold or water damage restoration
  • Foundation problems
  • Upgrading insulation
  • HVAC system extensions
  • Material delays or layout changes

DIY vs. Hiring a Professional

Hiring skilled contractors like On Point Renovations guarantees:

  • Quality workmanship
  • Timely project completion
