A plain-English guide for homeowners: what needs a permit, how long it takes, the inspection cutoff that catches people out, and how to check that your contractor is real.
This page exists because the question comes up on almost every job, and because the answers are scattered across a city website, a state statute and a code book. Here is the practical version for homeowners in Lake Mary.
Read this as orientation, not as authority. Codes, fees and procedures change. The City of Lake Mary Building Division is the only authority on what your specific project requires, and their permit portal and staff are genuinely helpful. Confirm before you rely on anything below.
The Lake Mary Building Division enforces the Florida Building Code, 8th Edition (2023), together with the 2020 National Electrical Code, along with state statutes and city ordinances. That matters to you in one concrete way: when a permitted job opens up existing work, the affected work is evaluated against today’s code, not the code in force when the house was built. This is why a panel replacement in a 1997 home frequently turns up grounding, bonding, AFCI or GFCI items that were perfectly legal at the time and are not now.
| Work | Permit | Notes |
|---|---|---|
| Panel replacement or service change | Yes | Always. Includes amperage changes and relocations. |
| New branch circuit | Yes | Any added circuit. |
| EV charger installation | Yes | Hardwired or receptacle-fed. |
| Generator or transfer switch | Yes | Often a gas or mechanical permit too. |
| Pool, spa or lanai wiring | Yes | Bonding requirements are strict and heavily inspected. |
| Rewiring, additions, remodels | Yes | Usually rough-in and final inspections. |
| Whole-home surge device at the panel | Usually | It is work inside the service panel. Confirm with the city. |
| Replacing a light fixture | No | Like-for-like replacement. |
| Replacing a switch or receptacle | No | Like-for-like. Replacing with GFCI is still fine. |
| Changing a breaker | Generally no | Same size, same type. Changing size is a different matter. |
Ask for the permit number. The most common way homeowners get burned is a contractor who says the permit is handled and never files. Ask for the number, and confirm the final inspection was passed and the permit closed. Any legitimate contractor will hand you both without hesitating.
Florida licenses electrical contractors through the Electrical Contractors’ Licensing Board within the Department of Business and Professional Regulation, under Chapter 489, Part II of the Florida Statutes. Two things follow from that:
Also ask for a certificate of insurance naming general liability and workers’ compensation. If an uninsured worker is injured in your home, that can become your problem.
Lake Mary turns over steadily — corporate relocations along the I-4 corridor keep the market moving. Unpermitted electrical work is one of the most common findings that stalls a closing, because a buyer’s inspector spots a panel that does not match the permit history and the lender’s underwriter wants it resolved. Resolving it under a 30-day contract deadline costs multiples of what doing it properly would have cost, and it happens with the leverage entirely on the buyer’s side.
The permit is not bureaucracy you are paying to satisfy. It is the documentation that the work in your walls was done to code and inspected by someone with no financial interest in saying so.
Florida law does allow an owner-builder exemption in limited circumstances for work on your own homestead property that you do not intend to sell or rent for a period after completion, and it requires you to appear in person and sign a disclosure statement acknowledging you are acting as your own contractor. In practice it is rarely a good idea for electrical work. You take on the liability, you must do the work personally rather than hiring unlicensed help, and any mistake follows the property title. For panel and service work, use a licensed contractor. Confirm current requirements directly with the City of Lake Mary Building Division before relying on any summary, including this one.
Straightforward residential electrical permits — panel changes, EV circuits, generator connections — are commonly issued within a few business days, and simple ones can be same-day or next-day. Anything requiring plan review takes longer. Inspections are the faster part: requests made before the 2:00pm cutoff are scheduled for the next business day. Timelines vary with the department's workload, so treat these as typical rather than guaranteed.
Three things, in rising order of expense. First, it surfaces during a home sale — buyers' inspectors flag unpermitted panel work constantly, and it can stall or kill a closing. Second, your insurer may deny a claim if a loss traces back to unpermitted work. Third, the city can require the work to be exposed and inspected retroactively, which sometimes means opening walls. There is usually a path to permitting existing work after the fact, but it costs more than doing it right the first time and occasionally means redoing it.
Generally no. Direct like-for-like replacement of a switch, receptacle or light fixture is normally treated as maintenance. The moment you add a circuit, change amperage, relocate a panel, run new wiring, or install a generator or EV charger, you are in permit territory. When in doubt, call the Building Division and ask — it is a two-minute phone call and they would far rather answer it than red-tag the work later.
