How Much Does a Basement Remodel Cost?

Kitchen and bath remodeling costs differ. The cost to remodel a basement can vary widely depending on the size of your basement, the extent of the renovations, and choices in finishes. In general, you can expect to spend between $15,000 and $35,000 for a basic to mid-range basement remodel. High-end luxury basement renovations with added bathrooms, wet bars, and other amenities can cost $70,000 or more.

Cost Per Square Foot for Basement Remodels

Looking at basement renovation costs per square foot can give you a good baseline for setting your budget. On average, expect to spend:

  • $100 – $200 per square foot for a basic basement remodel

  • $200 – $300 per square foot for a mid-range remodel with some custom features

  • $300+ per square foot for a high-end luxury basement

So if you have a 700-square-foot basement, you may spend around $70,000 to $210,000 depending on the finishes and amenities you choose.

What Impacts Your Basement Remodeling Costs?

Many factors influence the overall expense of refinishing a basement. Here are some of the biggest cost drivers to factor into your basement remodeling budget:

Size of Your Basement

The overall square footage and layout of your basement’s size directly impact the cost of remodeling it. The larger the area you want to renovate, the more expenses will add up for things like:

  • Basement walls and flooring: Larger basements require more drywall, framing materials, and flooring to cover the space. For example, finishing 700 square feet can cost over $14,000 more in materials than a 500 square-foot basement.

  • Furnishings and storage: Bigger basements will also need more furniture, storage cabinets, custom shelving, and built-ins to utilize the available room. These amenities can drive costs up quickly.

  • Plumbing: If you’re adding bathrooms or a wet bar, larger basements may need additional or longer piping runs which ramps up labor and material costs.

  • HVAC: Heating and cooling expenses scale up with basement square footage. It takes more powerful HVAC systems and additional ductwork to reach bigger spaces.

  • Electric and lighting: The larger your remodeled area, the more lighting, electrical outlets, AV wiring, etc need to be installed. This is especially true if finishing separate activity rooms.

  • Hallways and divisions: Basements with multiple rooms, hallways, and divisions are more complex to remodel than open-concept layouts. You need to account for costs to frame new walls, hang drywall in separate areas, finish trims properly around doorways, etc.

On the other hand, smaller basement spaces with less plumbing, simple lighting plans, and open floor plans can cost significantly less to remodel. A small basement renovation may range from $15,000-$30,000 while a sprawling 1,000+ square foot basement with multiple rooms and bathrooms will cost over $100,000 in many cases.

Level of Finish

An RSMeans data analysis found the typical cost per square foot for remodeling a basement falls in the range of $109.93 to $174.67 depending on the finishes and features included.

Are you looking for a simple unfinished basement with utilities and drywall? Or a luxuriously finished basement with custom built-ins, wet bars, and home theater rooms? The level of finish drives cost more than any other factor. Basic basements start around $15,000 while luxury remodels can cost over $100,000.

Structural Changes

Making structural changes like moving walls, adding support beams, installing egress windows, or finishing a basement with exposed pipes can significantly increase basement renovation costs. Here’s a breakdown:

  • Moving Walls: Eliminating or relocating walls to create an open-concept basement is a major undertaking. You need engineering approval, new load-bearing structures put in place, framing materials, drywall, flooring adjustments, and trim work. All said structural wall changes run $200 – $500 per linear foot.

  • Support Beams: If eliminating walls or ceilings, new steel I-beam supports must be properly sized, situated, and installed to prevent settling. Support beams alone can cost $3,000 to $15,000 depending on basement size.

  • Egress Windows: Egress windows involve specialized contractors to cut concrete foundation walls and install well-graded window wells leading outside. This provides emergency escape and rescue openings. Completing egress window updates ranges from $1,500 to $5,000 per window depending on challenges.

  • Exposed Pipes: Finishing a basement with open ceiling frameworks and exposed pipes, wires and ductwork (aka an “open concept basement”) cuts costs significantly compared to drywall ceilings. But some insulation and box work is still needed for a clean look.

Plumbing and HVAC

Any plumbing or HVAC work tacks on major expenses to your basement renovation budget, including:

  • Drain Lines: If you’re adding bathroom fixtures, wet bars, or laundry sinks, the work involves jackhammering concrete floors to access dirt beneath to install new drain lines. Combined with associated permits and labor, this plumbing can cost $7,000 to $15,000+.

  • Water Lines: Similarly, bringing water lines and supplies to new fixtures or appliances in a basement remodel runs pipes through floors and walls. Copper piping and professional connections are expensive.

  • HVAC Systems: Heating and cooling basements are crucial but require extending existing ductwork across open rafters or dropping ceilings to conceal everything. HVAC installations in remodels run $4,000 to $10,000.

  • Ventilation: Bathrooms and wet bars need added ventilation per code. Installs trigger electrician costs, permits, and carpentry expenses for vents leading outside.

Carefully consider which plumbing elements are must-haves versus nice-to-haves so you can scale the scope if needed to control these major expenses in your basement remodeling budget.

Electrical and Lighting

Updating old electrical panels, wiring new circuits, and installing recessed lighting, dimmers, and home theater setups ramps up costs quickly:

Circuit Boxes: A 200 amp panel (required for finished basements) costs $1,800 to $3,500 to install. New downstream circuits run $800 to $1,500 per room.

Wiring: All new code-approved wiring is ideal, including NM cables, conduit, junction boxes, and GFCI outlets. This can cost around $3,000 for a 700-square-foot basement.

Switches and Dimmers: Any switched fixtures like recessed lighting need dimmers or basic switches mounted in the walls and wired properly. These small parts and professional labor add a few thousand more.

AV Setups: Multi-room audio systems, whole house music, and home theater wiring can cost anywhere from $1,000 to the tens of thousands depending on the components chosen and the complexity of the configuration.

Meet with electricians to understand exactly what’s feasible or required within your budget. Controlling lighting, switch, and outlet upgrades is key to electrical savings.

Finishes and Flooring

Final finishes have a major influence on the style of your basement, but also the final costs. For example:

Drywall Texture: Smooth drywall finishes are the most affordable at around $1 per square foot. More dramatic knockdown textures run $4+ per square foot in materials and finishing labor.

Paint: Multiple accent walls or faux treatments add expense compared to two coats of neutral wall/ceiling paint at $0.75-$2 per square foot.

Trim and Moldings: Basic 1×4 pine trim costs under $2 per linear foot. But wider crown moldings, custom baseboard profiles, wainscoting, and other details cost exponentially more in materials and intensive carpentry work.

Flooring: This is one of the single biggest finish expenses. Hardwood floors for a 700-square-foot basement can cost over $7,000. Porcelain or ceramic tile ranges from $3,500 to $7,000. Sturdy waterproof vinyl plank offers huge savings of around $1,500.

Cabinets and Counters: Custom cabinetry and stone counters elevate a basement wet bar or kitchenette exponentially. Semi-custom cabinets cost $7,000+ and granite slab counters run $50-$200 per square foot installed.

Meet with your contractor to strike the right balance between design splurges and budget limitations for finishes. This is where you can scale back easily without sacrificing function.

Major Cost Components of a Basement Remodel

According to the National Association of the Remodeling Industry’s (NARI) 2023 Cost & Value Report, mid-range basement remodels cost an average of $98,239 and recoup about 53% of that in added home value.

To create an accurate basement remodeling budget, you need to look at all the potential work involved. Here are some of the main costs to factor in:


The biggest chunk of your budget will go towards construction labor. This includes framers, drywallers, plumbers, electricians, and finish carpenters. Expect to spend $50-$100 per hour.

Materials and Supplies

Everything from lumber and drywall to sinks, toilets, and lighting adds up. Budget about 40% of the total cost for materials.


Extending ductwork, adding ventilation, and installing climate control ranges from $4,000 to $10,000+.


Adding a bathroom or wet bar includes costs for new drain lines, water lines, fixtures, sinks, etc. Budget $7,000 to $15,000.

Electrical and Lighting

New circuits, wiring, recessed lighting, under-cabinet lighting, and dimmers cost around $3,500 to $7,500 depending on scope.


Hardwood floors in a 700-square-foot basement start around $7,000. Tile floors may range from $3,500 to $7,000.

Drywall and Paint

Hanging, mudding, and finishing drywall then priming and painting costs approximately $2 to $6 per square foot.

Permits and Fees

Don’t forget permit costs, which average $800-$1,500, plus 4-5% of project costs for inspection fees.

Contingency Funds

Also, build in a 10-15% contingency for any unexpected issues or cost overruns that arise.

Tips for Controlling Your Basement Remodel Costs

To make sure your basement remodel doesn’t blow your budget, here are great ways to save:

  • Get multiple bids and negotiate pricing

  • Complete prep work and demolition yourself

  • Shop sales and closeouts for supplies and fixtures

  • Use DIY options where possible (like paint and trim)

  • Scale back finishes or reduce the scope

  • Avoid moving walls or HVAC extensions

  • Install vinyl plank flooring instead of hardwood

  • Use recessed lighting sparingly

  • Consider energy efficient LED lights & fixtures

Also talk to your local building authority about rebates, tax incentives, and special financing programs that may be available in your area to help offset the investment into your home.

Every 500 square foot of finished basement space adds approximately 15% to your home’s value. So a basement remodel is a smart return on investment that quickly pays for itself when it comes time to sell.

Financing Your Basement Remodeling Project

A basement renovation often costs somewhere between $20,000 to $50,000. Very few homeowners can fund that fully out of pocket. Here are some of the most common ways to pay for basement remodeling projects:

Save up over Time

Open up a special savings account and set aside a fixed amount from each paycheck towards your basement renovation fund. It may take a few years to save up enough, but this approach allows you to pay cash.

Home Equity Loan

Many homeowners opt to take out a home equity loan or line of credit based on their home’s value. The benefit is low-interest rates and flexible payment options. Just be sure your monthly payments fit comfortably within your budget.

Credit Cards

You can charge basement remodeling expenses to a credit card short term. But interest rates are usually very high, so this is one of the most expensive financing routes. Make sure to pay off the balance as fast as possible.

Refinance Your Mortgage

Some homeowners wrap basement remodeling costs into a cash-out mortgage refinance. While interest rates are low, refinancing comes with upfront fees and closing costs.

Home Improvement Loans

Banks and credit unions often offer home improvement-specific loans with fixed rates and terms up to 20 years. This spreads payments out over a long period, but results in higher interest costs over time.

Grants and Rebates

Research any local, state, or federal tax rebates, grants, and incentive programs available. Some utility companies and municipalities offer rebates or financing plans for energy-efficient upgrades as well.

The most budget-friendly way to finance a basement remodel is to combine methods – for example, saving up over a few years while also taking advantage of a low-interest home equity loan or line of credit. Creating a financial plan from the start helps ensure you don’t overextend your budget.

To Sum Up

Remodeling your basement is a complex, expensive undertaking that requires careful planning and budgeting. While every project varies, you can expect to spend around $100-$200 per square foot for a mid-range to high-end remodel. Factors like the basement’s size, structural changes, and the extent of finishes and features impact the overall investment.

Get multiple detailed quotes, understand all potential costs, and build contingencies before setting your basement remodeling budget. Combining savings with low-interest financing over time is the most cost-effective way to fund your basement project. In the end, the added living space, functionality, and home value far outweigh the initial costs.
