How Much Does It Cost to Add a Bedroom and Bath in Minneapolis, MN? [2026 Data]

Many homeowners in Minneapolis, MN, choose to expand their existing homes rather than move, especially in established neighborhoods where larger homes can be difficult to find, and housing inventory remains competitive. Whether you're creating a private primary suite, adding space for a growing household, or improving your home's functionality, the cost to add a bedroom and bath in Minneapolis, MN, averages $108,258, with most projects ranging from $39,300 to $122,616.

Project costs vary based on the size of the addition, bathroom layout, and the materials and finishes selected. In Minneapolis, MN, homeowners may also encounter expenses related to foundation work, winter construction conditions, permitting requirements, and upgrades to plumbing, electrical, or HVAC systems. Understanding these local cost factors can help you establish a realistic budget and plan your addition with confidence.

Bedroom and Bath Addition Cost Factors 

Several factors influence the cost of a bedroom and bathroom addition in Minneapolis, MN, with the largest expenses tied to the bedroom's size, the type of en suite bathroom, and the materials and finishes selected. Demolition, site preparation, foundation work, and any required plumbing, electrical, or HVAC upgrades can also account for a significant portion of the total project budget.

Size of Primary Bedroom

A bedroom and bathroom addition costs an average of $170 per square foot. This rate can range from $85 to $230 per square foot, depending on the features you include and the finishes and materials you choose.

The footprint of a primary bedroom alone can range from 200 to 400 square feet. A primary bathroom can add another 50 to 200 square feet on top of that. Larger additions require higher material and labor costs, as detailed in the table below.

Type of En Suite Bathroom

Bathrooms are far more expensive to build on average than bedrooms, so expect the cost to add a bathroom to take up the majority of your project budget. If you're planning an en suite, understanding what an en suite bathroom is can help you determine which layout best fits your needs.

Your costs will vary significantly depending on the type of bathroom you want for your addition, as well as factors such as standard master bathroom sizes. Costs per bathroom type in Minneapolis, MN, break down as follows:

Materials

A primary bedroom requires a wide range of materials, from lumber for framing and support to a concrete foundation, siding, roofing, drywall, paint, doors, windows, electrical and plumbing equipment, and flooring. Expect to pay anywhere from $10,500 to $105,000 on materials alone, or $42,000 on average.

Demolition and Prep

Before construction can begin on your new bedroom and bathroom addition, the space must be completely cleared of landscaping features. Expect demolition and prep to cost between $1.35 and $2.10 per square foot.

Home Addition Pro Costs

The cost of hiring a home addition pro in Minneapolis, MN, includes more than construction labor alone. Your total project budget may also cover permits and inspections, licensing and insurance requirements, sales tax, and project management or general contractor fees that help keep the addition on schedule and compliant with local building codes. 

Labor

Labor for a bedroom and bathroom addition in Minneapolis, MN, accounts for 40% to 60% of the total project cost. Home addition contractors and specialized trades often charge the equivalent of $75 to $125 per hour, though most projects are quoted as a fixed-price contract.

For a bedroom and bathroom addition, permit and inspection costs often range from $1,500 to $5,000 or more, including building, plumbing, electrical, mechanical, plan review, and state surcharge fees.

Licensing, Insurance, and Certification

Minnesota requires residential building contractors to hold a state Residential Building Contractor license. Licensed contractors carry liability insurance and workers' compensation coverage, with these compliance costs built into project pricing and overhead rather than billed as separate line items.

Sales Tax

The combined sales tax rate in Minneapolis, MN, is just over 9%. Contractors pay sales tax on many building materials used in a home addition and factor those expenses into project estimates, though labor charges for permanent home improvements are not typically taxed separately.

Project Management and General Contractor Fees

Does Adding a Bedroom and Bath Increase Home Value?

For many Minneapolis, MN, homeowners, a bedroom and bathroom addition is both a lifestyle upgrade and a long-term investment. If you're wondering whether adding a bedroom increases home value, the answer is often yes, although the increase in resale value rarely matches the full construction cost.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
