Planning to add a new room, garage, or even a second story to your home? Home additions are exciting projects, but before you pick up a hammer or hire a contractor, there’s a crucial step you can’t skip: getting the proper permits.
In this blog, we’ll walk you through why permits are needed, what types of home additions typically require them, and how to navigate the permitting process smoothly.
Why Are Permits Important?
Permits are legal approvals issued by your local building authority. They ensure that your construction plans comply with zoning laws, safety codes, and building regulations.
Here’s why you shouldn’t skip them:
Safety: Permits ensure your addition meets safety standards.
Insurance: Unpermitted work may not be covered by homeowner’s insurance.
Resale Value: When you sell your home, unpermitted additions can lower your value or complicate the sale.
Fines & Legal Issues: Building without a permit can result in hefty fines or orders to tear down the addition.
What Types of Home Additions Require Permits?
While requirements can vary depending on your city or county, the following usually require permits:
Room additions (bedrooms, sunrooms, etc.)
Garage or carport construction
Second-story additions
Structural changes (e.g., removing or adding load-bearing walls)
Roof expansions or extensions
Plumbing and electrical work
Decks over a certain height (usually 30 inches)
Accessory Dwelling Units (ADUs)
Even small projects, like converting a basement into a living area, often require approval. Always check before starting.
Steps to Get a Permit for a Home Addition
Here’s a step-by-step breakdown of how to obtain a permit:
1. Check Local Building Codes
Visit your city’s website or building department to learn about the specific codes and zoning rules for your area. Every location has unique requirements.
2. Prepare Your Plans
You’ll need detailed architectural drawings or blueprints showing your addition’s dimensions, materials, electrical, and plumbing layouts.
3. Submit Your Application
Fill out a permit application and submit it along with your plans to your local permitting office. Some areas allow you to apply online.
4. Pay Permit Fees
Fees vary based on the size and complexity of your project. Be sure to ask about the total cost upfront.
5. Wait for Approval
The building department will review your plans. They may ask for revisions if something doesn’t comply. Once everything checks out, you’ll receive the green light.
6. Schedule Inspections
Throughout the construction process, inspectors will visit the site to ensure the work follows the approved plans and codes.
Common Mistakes to Avoid
Assuming small additions don’t need permits
Failing to account for setback and zoning rules
Hiring unlicensed contractors
Skipping inspections
If you’re unsure whether you need a permit, it’s better to ask your local building authority than to guess.
What Happens If You Build Without a Permit?
You could face serious consequences:
Stop-work orders
Fines
Difficulty selling your home later
Forced removal of the addition
Correcting unpermitted work later is usually more expensive than doing it right from the beginning.
Final Thoughts
Adding onto your home is a great way to gain more space and increase its value, but make sure to follow the proper permit process to avoid trouble down the line. Permits aren’t just red tape—they’re a key part of a safe and successful renovation.
Before starting your next home improvement project, do your research, talk to professionals, and get the permits you need. It’s the smart (and legal) way to build.
