Architect, residential designer or drafter? Who does what on a Tennessee home

Four words get used for the people who draw houses: architect, designer, draftsman and engineer. They are not interchangeable. In Tennessee, architect and engineer are licensed titles, as is landscape architect. Designer and draftsman are not. This guide explains who does what, where the licensing line sits and what to ask before you commit to a plan source for a house in Tennessee.

It is general information, not legal advice. Requirements differ by building type, size and jurisdiction, and they change, so the final word belongs to your local building department. Native Plans draws residential plans within those limits, and our FAQ on licensing and engineering covers how we handle stamps.

What is a draftsman?

A draftsman, also called a drafter or CAD technician, turns design decisions into drawings. They may work from sketches, a marked-up plan, a builder's standards or a stock plan. They are often strongest on the mechanics of a set: dimensions, framing layouts, schedules and sheet coordination. Drafters work inside builders, design firms and engineering firms, and on their own.

Drafting is a skill, not a license. A drafter does not take responsibility for a sealed set, and quality varies, so ask to see finished sets from real projects.

What is a residential designer?

Residential designer, building designer and home designer all describe someone who designs houses and prepares the drawings to build them without holding an architect's license. The titles are not tightly regulated, so training and experience vary. Some designers have degrees in architecture, some came up through building, and some hold voluntary professional credentials. Ask what they hold and verify it.

A good residential designer works on program, layout, massing, elevations and the construction details of a house, and knows how it will be framed and priced. Ask what they have drawn, what was built from it and who engineers the parts that need engineering.

What is the difference between an architect and a residential designer?

The difference is the license. An architect has met a state's education, experience and examination requirements and holds a license to practice. In Tennessee, as in other states, the title is protected, so someone who is not licensed should not call themselves an architect. An architect can seal drawings within the scope of the license, and can offer services beyond drawings, such as consultant coordination and observation during construction when contracted.

The line matters when the law, or the building department, requires a licensed professional's seal. That raises the question most builders actually have.

Do you need an architect to build a house in Tennessee?

Not always. Tennessee requires a licensed architect or engineer for many building types, but exemptions can apply to some residential work, depending on factors such as the type of building, how many units it has and its size. Local jurisdictions can add their own rules on top.

We are not going to quote a threshold from memory. A wrong number here costs you a permit delay, and the rules are the building department's to apply.

Other parties may ask for more than the law does. A lender, an HOA or design review board, a historic or hillside overlay, a floodplain, or a difficult site can each lead to a sealed set or an engineer's report even where the state does not require one.

Ask these questions, in this order.

1. Call the building codes or permits office for the city or county where the lot is. Give the building type, number of units, approximate size and construction method, and ask which drawings they require for a permit.
2. Ask whether any part of the drawings must be sealed by a licensed architect or engineer, and which parts. Structural, foundation and truss drawings are common candidates. Confirm for your project.
3. Ask about local reviews that apply to the lot: zoning, overlays, floodplain, stormwater, historic or design review.
4. Ask for the submittal checklist, the format and the number of sets.
5. Ask your lender, your insurer and any HOA or review board what they require separately.
6. For a licensing question rather than a permit question, contact the state board that licenses architects and engineers, the Tennessee Board of Architectural and Engineering Examiners.

Write down each answer with the date and the name of the person you spoke to. That record helps if requirements are applied differently later.

Who can draw up house plans?

Architects, engineers for their parts, residential designers, drafters, builders and sometimes owners all prepare house plans. Whether a given person can produce the plans for your house depends on the project-and-jurisdiction rules above. Whoever draws them, the building department judges the result by whether it shows the project clearly enough to review against code.

Can you draw your own house plans without an architect? Owners sometimes do. The set still has to meet the department's requirements and be buildable by the contractor, which is the harder part.

Do house plans need to be stamped?

A stamp or seal means a licensed professional takes professional responsibility for the sealed work, within the limits of the license. A set can carry more than one seal, for example one for structure and another for the building.

Whether yours needs one is the question above. If a seal is required, a licensed architect or engineer does the sealing. A designer or drafter cannot sign in their place.

Can an architect build a house?

An architect's license covers design services. Construction is licensed separately, as contracting, and an architect is not a contractor by virtue of the license. Some firms hold both and offer design-build. Ask who holds which license and who is accountable for what. Most houses are built by a licensed builder working from drawings.

What should you ask before hiring a designer or drafter?

The title tells you less than the work does. Before you commit, ask for the following.

• Finished sets from houses that were built, and a builder you can call about one of them.
• Who engineers the structure, the trusses and the foundation, and whether that work is inside their proposal or separate.
• How they handled plan review comments on past projects, and who answers the building department.
• How revisions are tracked, priced and approved.
• Which parts of the set they cannot do themselves, and who does those parts.

Do I need an architect or a designer?

A residential designer or drafter often fits when the program is clear, the building is a single-family house or similar small residential type, and the builder is running the project.

Bring in an architect when the jurisdiction or the lender requires it, when the project is large, multi-unit or mixed in use, when the site or structure is complex, or when the owner wants full architectural services including design leadership and construction observation. Many projects use both, with an architect or engineer on the sealed parts and a designer on the rest.

An interior designer replaces neither. Interior designers work on finishes, fixtures, lighting and furnishings, and coordinate them with the builder. Their decisions need to land at the right point in the build, which our selections timeline lays out.
