Who Prepares Each Part of a Residential Permit Package?

One of the biggest misconceptions in residential construction is that "the person who drew the house" is automatically responsible for every document needed for permitting. In reality, a permit package can combine work from several professionals, contractors, manufacturers, and agencies.

Residential Designer / Architectural Professional

This role commonly develops the building layout, floor plans, elevations, sections, and architectural details. Depending on the project, licensing requirements, and scope, an architect or other qualified professional may be involved. The key point for the owner is to define exactly what the design contract includes — and what it excludes.

Structural Engineer

The structural engineer may design foundations, framing systems, beams, columns, connections, and other structural components. Florida projects also require appropriate consideration of project-specific wind and other design loads.

Surveyor

A licensed surveying professional prepares survey documents within the contracted scope, establishing boundary and site information that the design team can use for building placement and coordination.

Mechanical / HVAC Professional

Mechanical documentation can involve HVAC load calculations, equipment selection, duct design, and related permit information. Some jurisdictions specify recognized ACCA calculation methods for new residential work.

Electrical and Plumbing Design

Electrical and plumbing documentation may be prepared or supported by appropriately qualified design professionals and/or licensed trade contractors depending on the project, jurisdiction, and legal scope. Owners should not assume those disciplines are automatically included in an architectural design agreement.

Energy-Compliance Provider

Energy calculations may be prepared using approved Florida compliance methods or software by professionals familiar with the project's envelope and mechanical information. These documents must coordinate with the actual permit plans.

Truss Manufacturer / Truss Engineer

When engineered trusses are used, the truss package is typically developed as delegated engineering based on the building geometry, loads, and support conditions provided by the project team. Jurisdictions may require truss engineering as part of the permit review. Orange County, for example, expressly lists it when applicable.

General Contractor

The contractor's role is not simply to build from whatever drawings arrive. A competent contractor reviews the package for constructability, scope coordination, permitting needs, trade sequencing, and field conflicts. The contractor also coordinates subcontractors, permit processes, inspections, and changes within the limits of the contractor's licensed role.

Building Department and Other Agencies

The building department does not design the project. It reviews the submitted information under the applicable regulatory process. Depending on the property, zoning, development engineering, utilities, health, environmental, or floodplain reviewers may also be involved.

The Owner's Most Important Question

Before paying for a plan package, ask each consultant what deliverables are included. A contract that says "house plans" may not mean electrical design, HVAC, energy calculations, survey, truss engineering, site plan, septic documentation, or permit coordination are included.
