Local Building Regulations And House 
Rewiring
Electricity powers many appliances and critical equipment in modern households and businesses, such as indoor climate control systems, water heaters, refrigerators, lighting and computers. We often take the safety and availability of our household and business electrical connections for granted without considering the demands modern appliances place on an electrical system. Inadequate wiring can cause several problems, including tripping breakers, damaging equipment and starting fires.
An experienced, licensed electrical contractor can evaluate the adequacy of your electrical system and recommend ways to upgrade it and enhance safety. In Florida, upgrading or rewiring the electrical systems of homes and businesses requires permits and must comply with state and local codes and building regulations.
Benefits of Rewiring and Upgrading Electrical Systems
Today’s households and businesses rely on an array of electrical devices to improve comfort, enhance efficiency and perform routine tasks. If you live in an older home, your electrical system may not be able to support the demand. You may notice lights flickering, breakers tripping or a reduction in power as you turn on and use appliances.
The electrical systems of older homes may not meet current codes. Service panels that support modern home electrical needs are often rated between 200 and 400 amperes depending on factors such as the size of your home and energy usage. Service panels in older homes typically have ratings of 100 amperes, which may not support usage. Overloaded systems can cause wiring and circuitry to heat up, causing fires.
Current building codes in Florida require important electrical safety features. Installing ground fault circuit interrupters in wet areas such as bathrooms and kitchens protect from shocks. Installing arc fault circuit interrupters prevent wires from overheating or arcing, a major cause of house fires.
Rewiring brings peace of mind. You know that your upgraded electrical system can handle your household’s load and reduce the likelihood of shocks and fires. Rewiring may also lower your homeowner’s insurance premiums by reducing the risk of fires and appliance failures.
Florida Electrical Codes and Regulations
Florida adheres to the National Electrical Code 2020 and the Florida Building Code, 8th edition of 2023. Electrical work in Florida must meet current codes and pass inspection. Working with the certified electricians from Sarasota Mr. Sparky ensures that your rewiring project will meet Florida’s current building codes and regulations.
Building permits are required in Florida for changes in structural components, including electrical, plumbing and mechanical systems. Sarasota County’s building permit guidelines provide detailed information about when a permit is required and the permitting process.
Permits for electrical work must be drawn by certified electrician. However, Florida allows homeowners to pull permits and complete electrical work themselves on primary residences. A homeowner permit includes several restrictions and conditions. It requires that you do the work yourself. If you hire a licensed professional for part of the work, that person must pull another permit. You must adhere to codes and pass inspection. Importantly, you cannot use an unlicensed person for the work. If you violate the terms of the permit, the work may not be approved, and you may have to apply for a new permit.
