16 Home Improvement Jobs I’ve Learned You Can’t Legally Do Yourself

You’ve got the skills and the drive to tackle that never-ending honey-do list around your house—like refinishing those floors or fixing that annoying leak. But before you swing that hammer, let’s talk about the legal side of DIY for a second.

Not all home projects are just a matter of skill and elbow grease. Some of them—yep, even the ones you’re totally capable of handling—might actually need a permit, or even a pro to sign off on them. And trust me, you don’t want to mess with your local building codes. Skipping out on a permit might not land you in a courtroom drama, but it could hit you with some annoying fines or, even worse, having to tear down all that hard work.

So, what should you do? Always check with your local authorities first. Building regulations can change fast, and you definitely don’t want to get halfway through a project only to discover it’s not on the up-and-up anymore.

These are 16 home improvement jobs that’ll get you into some hot water for doing yourself.

Stove Conversions

Switching your kitchen’s stove from electric to gas might sound simple, but it actually involves quite a bit of expertise. This type of conversion requires not only a gas line but also electrical adjustments. Because of the dual nature of this setup, both a licensed plumber and an electrician are typically needed to make sure everything is done safely and up to code.

These professionals will handle the installation and make sure that both the gas and electrical systems are functioning correctly and safely. Remember, regulations vary by state and locality, so these experts will also make sure your new stove meets all local codes.

Installing Lighting

Installing or replacing light fixtures might seem like an easy, everyday project, but there’s a lot at stake if it isn’t done correctly. Faulty wiring is a leading cause of house fires, which is why any significant lighting project should always involve a professional.

If a fire were to happen due to improper installation, not only could you face the loss of your home, but your insurance might not cover the damages if the work wasn’t permitted or done by a licensed electrician. Believe me, you don’t want that!

To protect your home and make sure that everything is up to standard, it’s best to hire a professional who knows what they’re doing and can navigate the local regulations.

HVAC Repairs or Installations

Tinkering with your HVAC system might seem like a good way to save a few bucks, but it’s a risky move that could end up costing you more than you bargained for. In many states, you need specific licenses to handle the potentially dangerous materials involved, like freon in air conditioners, which can lead to serious health issues like respiratory problems or even asphyxia if mishandled.

Here are a few HVAC projects that typically require professional expertise and a permit:

• Installing or replacing a furnace or air conditioning unit
• Major repairs that involve gas lines or refrigerants
• Expanding your HVAC system to new areas of your home

Doing this work without the proper certifications can be super dangerous and may also void your warranty and leave you liable for any resulting damages.

Backflow Preventer Installation

Installing a backflow preventer is super important for keeping your water supply safe from contamination. While it might seem like an easy DIY project, most places in the U.S. actually require a permit for it. This is to ensure the device is installed correctly and prevents any contaminated water from flowing back into the public water system.

Usually, you’ll need to hire a licensed plumber for the installation. Given the serious health risks associated with improper installation, following these regulations isn’t just about following the law, it’s about ensuring the safety and cleanliness of your water.

Well Installation

If you’re thinking about installing a well on your property, there are a few things you need to know. Drilling a well is more than just making a hole in the ground -it requires precise knowledge of geological formations and water safety.

Many jurisdictions mandate the use of licensed well drillers to make sure that the water drawn is safe and does not adversely affect the local water table. Even if it’s not legally required, relying on a professional’s knowledge and equipment is a smart choice so that you know your well is sustainable, safe, and compliant with any local environmental standards.

Roofing Projects

Thinking about replacing your roof? Hold off on grabbing those shingles and hammer. Roofing projects often require permits, especially for major jobs like a complete shingle replacement or structural modifications.

Local building authorities need to ensure that any structural changes meet safety standards and adhere to building codes, which can vary widely from one state to another. Common roofing jobs that might need a permit include:

• Complete replacement of roofing materials
• Structural changes, such as altering the roofline or installing skylights
• Adding roofing to new constructions or extensions

To avoid any legal or safety issues, your best bet is to contact local building authorities for the specifics about what’s required in your area before you begin. This ensures your roof work is legal, safe, and up to code.

Large Fence Projects

Planning to put up a new fence? It’s a great way to define your property boundaries and boost privacy, but first, you might need to tackle some legalities. In most places, if your fence exceeds six feet or involves more complex structures, you’ll likely need a permit. These permits ensure your fence meets local zoning laws and safety standards.

Always talk with your local building authority before you start digging. They can provide guidelines specific to your area, helping you stay compliant and neighbor-friendly.

Fireplace and Wood Stove Installation

Thinking about cozying up next to a new fireplace or wood stove this winter? While installing a prefabricated unit might seem pretty straightforward, any modifications or venting installations will definitely require a closer look -and likely a permit.

Why bother with permits for something as simple as a fireplace? Safety first:

• Venting requirements: Proper installation is crucial to ensure toxic fumes are correctly vented out of your home, preventing potential carbon monoxide poisoning.
• Fire safety: Incorrect installation could pose serious fire hazards. Consulting with your local fire marshall or building department can guide you on safe practices and any specific requirements.

Structural Changes

Considering making some big changes to your home, like knocking down walls or adding extensions? First, you should probably know that structural changes can significantly affect your home’s integrity. In fact, most U.S. jurisdictions will require the input of a licensed structural engineer to make sure that changes like these don’t compromise your home’s safety.

For projects such as removing walls to open up space or extending your home’s footprint, you’ll probably need a permit. Each state has its own regulations, so you’ll need to check with your local authorities. They’ll assess your plans to make sure all structural modifications are up to code, ensuring the long-term stability and safety of your home.

Gas Line Installation and Repairs

Dealing with gas installations and repairs carries some pretty big risks, including potential gas leaks that could lead to fires or carbon monoxide poisoning. That’s why, across most states, only a licensed professional is permitted to handle these jobs.

If you’re planning to install a new gas stove, replace a water heater, or repair existing gas lines, hiring a certified technician isn’t just a legal requirement, but a must-have for safety. Each state will have guidelines and permit requirements for these types of projects to ensure that they are executed safely, minimizing risks to you and your family.

Deck Building

Yes, most deck constructions require a permit, and here’s why: safety is paramount. A poorly built deck poses serious risks, not just to your family but also potentially affecting your home’s structure.

Here’s what you need to know about deck permits:

• Safety standards: Permits ensure that your deck adheres to local safety codes, especially important for elevated structures.
• Contractor requirements: Professional builders generally won’t risk their licenses by skipping the permit process, so following the rules helps everyone involved.
• Avoiding utility mishaps: Part of getting your permit will likely include having utilities marked to avoid accidents like hitting an electrical line. You can use services like Call811 to handle this.

If you aren’t sure about the condition of an existing deck, resources like the North American Deck and Railing Association offer checklists to help ensure it’s safe and up to code.

Pool Installation

Installing a pool isn’t as simple as just digging a hole and filling it with water. In most U.S. jurisdictions, pool installation is regulated and typically requires the involvement of licensed professionals.

Due to the complex nature of pool construction and the potential risks involved (like improper installation leading to leaks or collapses), it’s a job for experienced and licensed installers.

Remember to always check with your local building department for specific pool installation guidelines and permit requirements. This ensures your pool complies with local safety standards and zoning laws.

Tree Removal and Major Pruning

Before you grab that chainsaw, know this: not all tree removals are a DIY green light. Rules vary widely based on where you live. Some areas require permits, especially for large or heritage trees—these are trees recognized for their age, size, or historical significance. For instance, places like Portland, Oregon, mandate a special permit for removing these significant trees.

If you’re unsure about the specifics, it’s always a good first step to avoid legal headaches. You can also talk to an arborist. These tree experts can assess the health and risk of your tree and advise on the best course of action, whether that’s trimming back branches or taking down the whole tree.

And remember, removing large trees close to buildings or power lines is super risky and generally better left to professionals who have the right tools and know-how.

Electrical Repairs

When it comes to DIY electrical work, you really need to know when to call in the experts. Certain projects require permits because they pose significant safety risks if done incorrectly. Here are a few examples of electrical jobs that typically need a professional touch and a permit:

• Installing new electrical outlets or light fixtures
• Replacing circuit breakers
• Installing a central vacuum system
• Converting a kitchen range from electric to gas
• Upgrading or repairing hard-wired electrical systems

These projects involve extensive knowledge of your home’s electrical system and adherence to local electrical codes, designed to prevent fire hazards and electrocutions. For safety and compliance, just leave this work to licensed electricians.

Major Plumbing Projects

Plumbing work usually requires a pretty deep understanding of both the jobs and local codes, which is why many big plumbing projects are illegal to DIY. Here are some common plumbing jobs that generally require a permit:

• Moving a plumbing fixture more than six feet
• Installing a new plumbing fixture where one didn’t previously exist
• Major pipe repairs or replacements
• Installing or repairing septic systems and water heaters

These jobs can lead to serious problems, like leaks, floods, and contamination if you don’t do them right.

Septic System Installation

If you’re thinking about installing a septic system, you should know this typically isn’t a DIY project. Most local regulations require the installation to be done by a state-licensed plumber or a registered contractor. The reason is simple: septic systems involve complex installation processes that have to adhere to specific health and environmental standards.

Before starting any work, make sure to contact your local health department or building authority to understand the specific requirements and permits needed. They can guide you through the process and help make sure your installation is done safely and in compliance with local laws.
