Hiring a Home Addition Contractor in the North Metro

A home addition contractor builds new square footage onto your existing house: a room addition, a house expansion, a home add-on, a second story, or a new bathroom where none existed before. Whatever name the project goes by, the work is the same discipline, foundation, framing, roofline tie-in, permits, and finish that matches the house you already own. Powerbuilt Construction is a licensed MN general contractor serving Centerville, Plymouth, Maple Grove, and the greater North Metro, and Bob walks every job himself. Call Bob at (763) 331-2247 and describe what you're working with. Powerbuilt holds MN General Contractor License #BC533891, and we pull permits on every addition we build.

Home addition construction covers a wide range of project types: a main-floor bedroom addition, a garage addition, a second story, a bump-out to expand a cramped kitchen, or a brand-new bathroom built into square footage that doesn't exist yet. Each of those projects has a different cost structure driven by foundation requirements, roof tie-in complexity, exterior finish matching, and how much existing structure we're connecting to. Additions at the smaller end, like a single bathroom rough-in on an existing slab, can be completed for a fraction of what a full two-story addition costs. In some cases you don't need to build out at all; reclaiming an attached garage as finished living space can add the room you're after without a new foundation. We won't quote you a number that doesn't fit your actual house. Every job is different, contact Powerbuilt Construction for an accurate estimate. You can also browse our home renovations page if your project blends addition work with broader remodel scope.

Room Additions, House Expansions, and Home Add-Ons We Build Addition Types

We handle the full scope of residential addition construction, from single-room buildouts to full second-story house expansions.

01

Bathroom Additions

New bathroom construction in space that doesn't have one yet. We handle framing, plumbing rough-in coordination, electrical, tile, fixtures, and finish carpentry. Both above-grade and basement bath additions.

02

Room Additions

Main-floor bedroom, office, or living space additions attached to the existing structure. Includes foundation, exterior walls, roofline tie-in, insulation, and interior finish to match the home.

03

Second-Story Additions

Full second-floor additions built over an existing single-story home. Requires structural assessment of the existing foundation and first-floor framing before we scope the build.

04

Garage Additions

Attached or detached garage construction, including concrete work, framing, overhead doors, and interior finishing. Permitted through the local municipality on every project.

05

Kitchen Bump-Outs

Expanding a tight kitchen by pushing an exterior wall out 4 to 10 feet. Smaller footprint than a full addition, but the structural and exterior work is identical in scope.

06

Accessory Buildings

Standalone structures on the property for storage, workshop, or hobby space. Built to local code with proper permits, not as unpermitted outbuildings.

Straight pricing

The first number is the real number.

A remodel or a new build is one of the biggest investments you will ever make, so the price up front deserves straight talk — and how a contractor handles it tells you how the whole project will go. If they play games before the work starts, they will play games after it. Powerbuilt gives you the best possible price the first time, no haggling and no hard selling, from a reputable company that has to stand behind the work.

You have seen the outfits that come in high, then chip the price down every time you hesitate, tossing in 'free' labor and one-day-only deals to rush a signature. Powerbuilt does not work that way. Bob walks the job, then gives you one straight bid for your addition, in writing, and it holds whether you sign today or next month.

HOW IT WORKS

From Site Walk to Finished Addition

  1. 01

    Site Assessment and Scope

    Bob walks the property, reviews what you want to build, and identifies the structural, mechanical, and permitting requirements. No guessing. The scope gets locked before any number is discussed.

  2. 02

    Permits and Foundation Work

    We pull permits through your municipality before breaking ground. Foundation work comes first: footings, slab, or crawl space depending on what the addition requires and what code specifies.

  3. 03

    Framing Through Finish

    Framing, exterior sheathing, roofline tie-in, insulation, drywall, interior trim, and all finish work. We coordinate subcontractors for plumbing and electrical so you're not managing multiple crews.

LICENSED WORK

Why a License Number Matters on Addition Work

bathroom additions work, professional service in Ham Lake, MN
Home additions aren't remodel work. They involve new foundation elements, exterior wall construction, roofline modifications, and connection to existing structure, all of which require a licensed general contractor in Minnesota. Unlicensed operators can't legally pull permits for this scope, which means you can't get a final inspection, which means your addition doesn't exist on paper when you go to sell or refinance. Powerbuilt Construction holds MN GC License #BC533891. We've completed addition projects from single bathroom builds to full second-story additions, and every one of them closed with a passed final inspection. You're not hiring a handyman for this job. You're hiring a licensed contractor who answers the phone and pulls permits. Call Bob at (763) 331-2247 to talk through what you're planning. We also take on custom home building projects for clients building from the ground up.

Common Questions About Home Addition Construction

What does a bathroom addition cost in Minnesota?
Bathroom addition costs vary based on whether you're building into existing square footage or adding new exterior square footage. A basement bathroom rough-in in existing space costs far less than a full above-grade addition with new framing and a foundation. Costs also shift based on fixture selections, tile scope, and how much plumbing needs to be extended. Every job is different, contact Powerbuilt Construction for an accurate estimate on your specific project.
Do home additions require a permit in the North Metro Twin Cities?
Yes. Any addition that involves new square footage, structural modifications, or new plumbing requires a building permit through your municipality. In Anoka County cities like Andover, Blaine, and Coon Rapids, you'll also need inspections at multiple stages: foundation, framing, rough-in, and final. Powerbuilt Construction handles the permit application process on every addition we build. We won't start framing until the permit is posted.
Can an existing foundation support a second-story addition?
Sometimes yes, sometimes no. It depends on the age of the foundation, the original design load, the size of the proposed addition, and soil conditions. Before we scope a second-story addition, we assess the existing first-floor framing and foundation to determine whether reinforcement is needed. Skipping that step is how second-story additions end up with structural problems five years later. We assess first, scope second.
How long does a home addition take to complete?
A small single-room or bathroom addition typically runs six to twelve weeks from permit approval to final inspection, depending on weather, material lead times, and inspection scheduling. Larger additions, including second stories or full wing additions, run longer. The permit process alone adds two to four weeks before any ground gets broken. We give you a realistic project timeline at the estimate stage, not an optimistic one designed to close the sale.
What's the difference between a bump-out and a full addition?
A bump-out extends an existing room by pushing one exterior wall outward, typically two to eight feet, without adding a separate foundation or roofline structure. It's a smaller scope and lower cost than a full addition. A full addition is an entirely new room or set of rooms with its own foundation, framing, and roof tie-in. Both require permits. The right choice depends on what you need the space to do and how your existing structure is positioned.
Is a room addition the same as a house expansion or a home add-on?
Yes, those are different names for the same work. Homeowners search for a room addition contractor, a house expansion construction company, a home extension contractor, or a home add-on builder depending on the phrasing they grew up with, but they all describe adding new, permitted square footage onto an existing home. Powerbuilt Construction handles the full range under one MN general contractor license, whether it's a single room, a second story, or a larger house expansion. We build these across the North Metro, including Centerville, Plymouth, and Maple Grove.
Does Powerbuilt Construction handle both the general contracting and the subcontractor coordination?
Yes. As a licensed general contractor, Powerbuilt manages the full project including coordinating licensed plumbers and electricians for rough-in work. You're not juggling multiple separate contractors. Bob runs the job and holds the GC license, which means there's one point of accountability from permit application through final inspection. We also handle general building construction for clients with broader scope beyond a single addition.
