What Does a Home Addition Cost in Pennsylvania?

The average home addition cost in Pennsylvania typically ranges from $70,000 to $175,000, with larger or second-story additions often falling between $100,000 and $500,000+. The exact price of a house addition depends on several key factors that can influence your total investment such as.

Type of Addition: Adding a single bedroom, kitchen extension, or family room costs less than constructing a full second story or in-law suite.
Square Footage: The larger the footprint, the higher the material and labor costs.
Location: Building costs vary across Pennsylvania. Urban or high-demand areas may have higher rates than rural communities.
Design Complexity: Custom layouts, vaulted ceilings, or special finishes add to both time and expense to the home addition cost.
Foundation & Structural Work: If new footers, roofing tie-ins, or reinforcement are required, costs increase.
Local Codes & HOA Rules: Permitting, zoning, and neighborhood association approvals can add time and fees to your project.
Material Choices: Premium siding, windows, or roofing can raise your final home addition estimate.

Do You Really Need to Hire Professional Home Expansion Contractors?

Excellent

Choice Windows, Doors & More, Inc.

We recently completed a major renovation with Choice Home Remodeling, and we couldn’t be happier with the results. This project involved a full first-floor layout change, a brand new kitchen, adding a bathroom, and a roof replacement—so it was a significant undertaking. From start to finish, their team handled everything with professionalism, organization, and clear communication.

One thing that really sets them apart is their consistency. We’ve used Choice Home Remodeling for several projects over the years, including smaller jobs, and they approach every project—big or small—with the same level of care, attention to detail, and commitment to quality.

Throughout this renovation, they kept us informed every step of the way and were always proactive when it came to addressing questions or unexpected challenges. The craftsmanship is excellent, and it’s obvious they take pride in their work.

We’re thrilled with how everything turned out and would highly recommend Choice Home Remodeling to anyone looking for a reliable, skilled, and trustworthy contractor.

Response from the owner:Thank you Keith for your kind words and five star review. It is always a pleasure working with you. We can't wait to get your pictures posted to our website!!

They always do a good job, and the installers were friendly. And answered any questions I had.

Response from the owner:Thank you Penne for the review and allowing us to work with you again, this time on your Patio Door. We look forward to how we can assist you in the future.

We recently replaced our original 2007 steel front door and had a great experience with Choice. Tim was very patient and helpful throughout the process, making sure we found the right door for our style and budget. We made three trips before deciding and never felt pressured.

The installer was also excellent—professional, polite, and clearly very skilled. You can tell he takes pride in his work.

We’re extremely happy with the end result and would definitely recommend Choice to anyone looking to upgrade their front door.
