If you are planning to remodel in St. Johns County, the safe starting point is to check permit requirements before work begins. The county says an owner or authorized agent who plans covered construction, enlargement, alteration, repair, demolition, an occupancy change, or regulated electrical, gas, mechanical, or plumbing work must apply to the building official and obtain the required permit.
That does not mean every update to a home follows the same path. The scope of work, the property, and the systems involved all matter. Here is a practical way to start the conversation.
Start by defining the work
Write down what will change, not just the room name. A kitchen project, for example, may involve only finishes, or it may also change plumbing, electrical, ventilation, walls, or layout. An outdoor project may involve a new structure, connections to the home, or regulated systems.
A clear scope helps you ask better questions about permits, plans, inspections, and responsibilities.
Ask whether the project changes a regulated part of the home
St. Johns County's guidance specifically includes work involving a building or structure and regulated electrical, gas, mechanical, or plumbing systems. If your project enlarges, alters, repairs, removes, converts, or replaces one of those systems, ask the county or the professional handling the work how permitting applies to that exact scope.
Do not rely on a neighbor's project or a general rule of thumb. Two homes can have different conditions, records, or requirements.
Understand what plan review considers
The county says plan submittals are reviewed for compliance with the Florida Building Code, Land Development Code, and other applicable laws. That review is one reason the details of the project matter early.
Before finalizing a design or signing off on a scope, ask:
- What drawings or documents will be needed?
- Which parts of the work may need separate trade permits?
- Who will prepare and submit the permit application?
- Who will respond if the county requests additional information?
- What inspections should the homeowner expect during the work?
These questions do not replace a determination from the building official. They help make responsibilities visible before construction starts.
Check property-specific constraints too
St. Johns County notes that restrictions in county public records may limit development and that water-management districts, state agencies, or federal agencies may require additional permits. Those constraints can be relevant even when the project seems straightforward.
For an addition, renovation, patio, deck, or other change to a property, it is worth asking early whether there are recorded restrictions or outside approvals to investigate. Addressing that question before work begins can help avoid treating a property-specific issue as a surprise later in the process.
Clarify who is responsible for the permit process
Ask the county who may submit the permit for your exact project. When speaking with a contractor or design-build team, ask who will handle the application, what that work includes, and how required inspections will be coordinated. Confirm any licensing, registration, or insurance requirements with the appropriate county or state authority rather than relying on a general assumption.
A simple pre-project checklist
Before moving from an idea to construction, gather:
- A written description of the proposed work
- The property address and parcel information
- Questions about structural or system changes
- Any known deed, HOA, or site restrictions to investigate
- The name of the person or company expected to handle permit responsibilities
- A list of licensing, registration, or insurance questions to verify with the appropriate authority
For a current, property-specific answer, contact the St. Johns County Building Department with the property address and a written description of the proposed work. Ask what permit category applies, what documents are required, and who may submit them.
The bottom line
A remodel may need a permit when it involves the kinds of construction or regulated systems identified by St. Johns County. The right answer depends on the actual scope and property, so confirm requirements with the county before work begins. Early clarification of the scope, documentation, permit responsibilities, and property constraints gives you a more organized starting point for the project.
