Are you planning a home improvement project? Before you dive in, understanding building permit requirements is crucial. Many common remodeling projects require permits, but knowing which ones apply to your project can save you time, money, and future headaches. Here’s a clear guide on when a building permit is necessary, what projects typically require them, and the risks of skipping this essential step.

When Is a Building Permit Required?

Building codes and permit requirements vary by location. Still, generally, any project that changes the structure or footprint of your home, or impacts the electrical, plumbing, or HVAC systems, will require a permit. Here are some common projects that often need one:

• Structural Changes: Any project that involves adding or removing load-bearing walls, or creating new rooms.

• Exterior Additions: Building an in-ground pool, adding a deck or porch, or constructing a new garage or shed.

• Major Roofing Projects: Roof replacements often need inspection for safety and adherence to local standards.

• Concrete Work: Installing concrete sidewalks, driveways, or foundation slabs.

Even smaller-scale projects, like adding a new window to an existing wall, usually require a permit because they impact your home’s structure and safety.

Why Permits Matter: Protecting Your Home and Investment

Permits aren't just about local regulations—they’re a safeguard for homeowners. When a permit is issued, the work must pass inspection by city or county officials at various stages. These inspections verify that the work complies with current health and safety codes, protecting your property value and long-term investment.

Michael Harris, president of BRY-JO Roofing & Remodeling, emphasizes the importance of permits. “When you file for a permit, city inspections ensure the work complies with safety codes. This protects homeowners by confirming the project meets structural and health standards.”

Skipping permits can lead to serious problems. For instance, BRY-JO discovered major structural issues in a bathroom addition that previous owners completed without a permit. Non-compliant plumbing, electrical, and framing posed serious risks, including a structural flaw that caused a second-floor room to pull away from the home. Correcting these issues ultimately cost an additional $8,000—an expense that could have been avoided had the original work been properly permitted and inspected.

When Permits Are Typically Unnecessary

For projects that simply refresh existing structures without altering their essential features, a permit is usually unnecessary. This includes updates like:

• Aesthetic Changes: Painting, wallpapering, and replacing flooring or ceiling finishes.

• Interior Decor Updates: Applying new cabinet doors or adding laminate doesn’t require a permit.

However, even if a permit isn’t required, hiring licensed professionals for work involving electrical, plumbing, or structural elements is always a smart choice.

Risks of Skipping the Permit Process

Foregoing a required permit can lead to significant complications. If a city inspector discovers unpermitted work, they may halt the project until you obtain the necessary approvals, potentially leaving you without a functioning kitchen or bathroom for weeks, plus a hefty fine.

Moreover, unpermitted work can impact future property sales or refinancing.  Unpermitted additions can trigger appraisal discrepancies. If the appraiser’s square footage doesn’t match county records, it can lead to issues with loans. Lenders and insurance carriers may view illegal construction as a risk, which could affect your ability to sell or refinance.”

Final Tips for Homeowners: Avoid Costly Delays and Fines

To avoid delays, ensure you obtain any necessary permits before starting your project. If you’re working with a contractor, it’s generally best to have them handle the permitting process. They are familiar with the requirements and can answer questions from inspectors, helping the process go smoothly.

In conclusion, taking the time to understand permit requirements protects your investment and ensures your renovation is done safely and to code. Whether you’re building a new deck or renovating a bathroom, permits are a small step that provides peace of mind and preserves the value of your Pittsburgh home. As a former owner of an award-winning home inspection company I can tell you that about 75% of the decks I inspected failed the inspection and talking to a local code official, his number is higher. The decks were likely constructed without permit.
