Whether you’re adding a master suite, expanding our kitchen, or building a second story, a  home addition is one of the biggest investments you’ll make in your home. Proper planning can  save thousands of dollars, reduce delays, and ensure your newly finished space serves a  purpose that is right for you.  

Here’s what every homeowner should know before beginning a home addition project. 

Define Your Goals  

Think about why you are adding more space to your home. Taking the time to clearly define  your goals up front will help shape every decision that follows. Create a list of priorities of  must-haves and nice-to-haves. Ask yourself questions like:  

• How will you be using this new space? 
• Are your needs temporary or long-term? 
• How important is resale value? 
• Is remodeling your existing space a better option? 

Understand Your Property  

Before drawing plans and getting too far ahead into the project, determine whether your  property can accommodate an addition. Getting a professional site evaluation early in the  process can prevent expensive redesigns or permit delays later. Review items like:  

• Property setbacks 
• Easements 
• Flood zones 
• Existing utilities 
• Septic or well location 
• HOA restrictions 

Establish Your Budget  

There is more to consider than simply the costs of construction. A professional contractor can  help you estimate these costs, but as you plan ahead it's important to consider the following  when creating a budget: 

• Design or engineering fees 
• Permits 
• Utility upgrades 
• Site construction work 
• Finishing selections 
• Contingency (10-15%) 

Design Around Your Lifestyle 

Think long term. The perfect addition will be able to solve today’s problems while preparing for tomorrow. Consider questions like: 

• Will you age in place? 
• Would you like ADA compliant doorways and fixtures? 
• Future first-floor bedroom? 
• A larger kitchen? 
• Future family gathering space? 
• More natural light? 

Choose the Right Addition

Garage Addition

Second Story

Obtain Proper Permits 

Depending on the township, most additions require a combination of the following permits with inspections occurring between each phase of the project: 

• Zoning approval 
• Building permit 
• Electrical permit 
• Plumbing permit 
• HVAC permit

Select Materials Early  

Many delays can occur because of homeowners waiting too long to choose finishes. Ensure  that your contractor has clear communication on what all of your options are and when the  deadline for your decision is to keep the project on schedule. Early selections keep the projects  moving.  

Prepare for Construction  

Construction affects daily life. A good contractor will explain the process before it begins, but it is  helpful to know what to prepare for ahead of time. Plan for things like:  

• Dust control 
• Noise 
• Parking of work vehicles around the property 
• Material deliveries 
• On-site dumpsters or outhouses 

Work With a Design-Build Contractor  

Having one team in charge from concept to completion improves communication, minimizes  costly surprises, and can save you headaches. A professional company like this will manage the  design, budget, permits, scheduling, and construction, along with any subcontractors that may  be involved in building a multifaceted addition.  

Don’t Forget the Exterior  

It’s easy to spend so much time focusing on the interior of the space and how it will be used,  that the finishing exterior touches that make the addition look seamless can get forgotten. When  finished properly, visitors shouldn’t be able to tell where the original home ends and the addition  begins. You should consider the following:  

• Matching rooflines 
• Siding 
• Windows 
• Trim 
• Gutters 
• Exterior lighting
