If you're planning a custom home in Georgia, the Carolinas, or anywhere in the Southeast, that question comes up early. It also comes with a lot of confident but conflicting answers. The truth is more specific — and more useful — than most of what you'll find online.
This guide explains what each role actually does, when the law requires a licensed architect (and when it doesn't), and how to put together the right team for a luxury custom home. The short version: most high-end single-family homes in Metro Atlanta and across the Southeast are designed by experienced residential designers, not architects — legally, deliberately, and with excellent results. Whether that's the right path for your project depends on the specifics.
The Three Roles, at a Glance
Before unpacking each one, here is the clearest distinction between the three:
- A licensed architect is a state-credentialed professional who can apply a professional seal to construction documents and assumes legal responsibility for their technical correctness.
- A residential designer produces the same deliverables — floor plans, elevations, sections, schedules, construction details — without the state license, which is permitted by law for most single-family residential work across the Southeast.
- A builder (general contractor) takes those documents, prices them, hires subcontractors, manages the site, and delivers the finished home.
| Role | Primary Scope | When Legally Required | Best Fit |
|---|---|---|---|
| Licensed Architect | Full building design, code and life-safety compliance, commercial and complex residential | Multi-family, mixed-use, commercial, and certain higher-risk occupancies; varies by state | Projects requiring an architect's seal, or where the client specifically wants a licensed professional |
| Residential Designer | Custom home design and complete construction documentation; engineering coordination | One- and two-family residences in most Southeast states; confirm with local building department | Luxury single-family custom homes where design depth and buildability expertise matter |
| Builder / General Contractor | Pricing, subcontractor management, site execution, schedule and budget | Licensed contractor required for construction above certain cost thresholds; not a design credential | Converting a complete set of construction documents into a built home |
In a typical luxury custom home project, the designer works with you for six to eighteen months developing the design and producing permit-ready construction documents. The builder then works for twelve to twenty-four months executing them. These roles are sequential — and that order matters more than most clients realize.
What a Licensed Architect Does
An architect has completed an accredited architecture degree (typically a five-year B.Arch or three-year M.Arch following a bachelor's degree), served several thousand hours of supervised internship under a licensed architect, and passed the multi-part Architect Registration Examination. That credential allows them to use the protected title and to apply their professional seal to construction documents — meaning they accept legal and professional responsibility for the technical accuracy of the design.
On a custom home project, an architect typically handles the full design process: programming, schematic design, design development, construction documents, and often construction administration. Residential architecture fees generally range from six to twelve percent of construction cost, depending on scope and location.
Architects are required by law for most commercial and multi-family projects. For single-family residential work, the requirements vary significantly by state — which leads directly to the next question.
Do I Need a Licensed Architect for a Custom Home?
For most luxury single-family homes in the Southeast, the answer is no — not legally. But "not legally required" and "not beneficial" are different questions, and it's worth understanding both.
When the Law Requires an Architect (State by State)
The following is a general summary of residential exemptions in the states where we most commonly work. This is not legal advice; statutes change and local jurisdictions sometimes impose additional requirements.
Georgia — O.C.G.A. § 43-4-14 explicitly exempts construction documents for one- and two-family residences and domestic outbuildings from the architect seal requirement, regardless of cost and with no square-footage cap. The seal requirement applies to other building types, including single-story structures over 5,000 square feet for certain occupancies and any multi-family or commercial work. For the standard luxury single-family custom home — the projects we design most often in Metro Atlanta — a qualified residential designer can produce permit-ready documents that local building departments, including Fulton, Forsyth, Cherokee, and Gwinnett counties, will accept.
South Carolina — S.C. Code § 40-3-290(C) similarly exempts one- and two-family dwellings (including townhouses) within the prescriptive scope of the South Carolina Residential Code from the architect requirement. Other carve-outs exist for farm buildings and small non-residential structures under three stories and under 5,000 square feet. Assembly, institutional, educational, and hazardous occupancies always require an architect's seal regardless of size.
North Carolina — N.C. Gen. Stat. § 83A-13 allows unlicensed designers to prepare plans for single-family residences up through eight attached units with grade-level exits, provided the structure is freestanding. There is no explicit square-footage cap on these exempt residential projects. Subsection (d) also preserves an individual's right to prepare plans for buildings intended for their own use.
Virginia — Va. Code § 54.1-402.A.1 exempts unlicensed designers from preparing plans for single-family homes, two-family homes, townhouses, and multifamily dwellings up to three stories — broader on the multifamily side than Georgia or South Carolina, but with a height cap that the others do not impose. The exemption excludes electrical and mechanical systems and does not extend to "unique design of structural elements" or to high-hazard occupancies, both of which require a licensed architect.
Florida — Fla. Stat. § 481.229 is among the most permissive in the region, exempting one- and two-family residences, townhouses, and domestic outbuildings from the architect requirement regardless of cost, square footage, or height. Farm buildings are exempt, and other building types under $25,000 in construction cost are generally exempt, with the exception of schools, auditoriums, and structures intended for public assembly.
Tennessee — Tenn. Code Ann. § 62-2-102(b) exempts one- and two-family dwellings and their domestic outbuildings, with no explicit square-footage or height cap. Assembly, institutional, and educational occupancies always require a registered architect or engineer regardless of size.
Alabama — Ala. Code § 34-2-32(b) takes a narrower approach: the residential exemption covers single-family residences only (not two-family dwellings, unlike Georgia or Tennessee), with no square-footage cap on those single-family homes. Other building types are exempt only below 2,500 square feet, and assembly occupancies always require a registered architect.
The practical takeaway: If you're building a single-family custom home anywhere in Georgia or across most of the Southeast, you are not legally required to use a licensed architect. Confirm specifics with your local building department before signing any design contract.
When You Might Choose an Architect Anyway
The legal exemption is not a reason to avoid architects — it's a reason you have a choice. There are legitimate situations where a licensed architect is the better fit:
- Your project includes a multi-family component, mixed-use element, or commercial space
- Your jurisdiction has imposed requirements beyond what state law mandates
- The structural systems involved are unusually complex
- You personally prefer the credential and the professional accountability that comes with it
The real question is not "architect or designer" but "is this person, with this experience, the right partner for this project?" The credential matters less than the judgment, the process, and the depth of residential experience behind the drawings.
What a Residential Designer Does
A residential designer produces complete construction documents for new homes, additions, and renovations: floor plans with full dimensions, exterior elevations with material callouts, building and wall sections, roof plans, interior elevations for kitchens and bathrooms, door and window schedules, finish schedules, electrical plans, structural coordination drawings, and specification notes.
The deliverables are functionally identical to what an architect would produce. The difference is the credential, not the document set.
Where residential designers often have an edge on luxury custom homes: depth of focus. A firm that designs nothing but high-end single-family residences develops a granular understanding of the details that drive cost, complexity, and livability in that specific building type — complex roof geometry, custom millwork sequencing, integrated outdoor living, the relationship between siting and natural light, the spatial flow that makes a home feel effortless rather than oversized. An architect with a broad commercial practice can design a beautiful home. A designer who has done nothing else for two decades typically understands the residential details at a different level.
Design fees for residential designers typically range from 1.5% to 3.5% of construction cost for full-service engagements on new construction, with phase-limited scopes running lower. For a $2.5M home in Metro Atlanta, that range puts design fees roughly between $37,500 and $87,500 depending on size, complexity, and scope of involvement during construction.
What a Builder Does
The builder — also called a general contractor or GC — holds the construction contract with you. Their job is to take a complete set of construction documents and deliver the physical home: hire and coordinate subcontractors across every trade, procure materials, manage the construction schedule, run the job site, handle inspections, and field questions from the design team as they arise.
Builders are paid through the construction contract itself, typically structured as a fixed-price (lump sum) contract, a cost-plus contract with a fee or percentage markup, or a guaranteed maximum price arrangement. In Metro Atlanta, total construction cost for luxury custom homes typically runs $350 to $600+ per square foot, depending on finishes, structural complexity, and site conditions.
A good builder is more than an executor. They identify problems in the documents before those problems become expensive field conditions. They suggest cost-saving substitutions that preserve design intent. They manage subcontractors who deliver consistent quality on a schedule. When a designer's documents are clear and complete, a good builder's job becomes measurably easier — fewer RFIs, fewer allowances, less time spent resolving ambiguity in the field. That relationship between documentation quality and construction efficiency is something we think about on every project we design.
A builder whose documents are vague or incomplete faces a different job entirely: constant improvisation, frequent change orders, and budget variance that rarely resolves in the client's favor.
The Practical Reality: Design First. Always.
Strip away the credentialing distinctions and the typical luxury custom home in Georgia involves two primary parties: a design professional and a builder, with engineering consultants — structural, civil, MEP — brought in for specific scopes.
The most consequential sequencing decision you'll make is which one you hire first. The correct answer is the designer.
Hiring a builder before design is complete locks you into that builder's preferences, subcontractor relationships, and pricing assumptions before you have anything concrete to bid. You also lose your negotiating leverage on the construction side before you've even used it.
The right sequence: engage your designer, complete design through construction documents, then bid those documents to two or three qualified builders. That is the only way to get comparable pricing, verify that your project is actually buildable within your budget, and walk into the construction contract with full information on both sides.
Builders should be involved during design development for preliminary pricing conversations — not before, and not in place of a designer doing their job. The right order for hiring designer, builder, and engineers goes deeper into the sequencing.
How Daniel Allen Designs Fits Into This
Daniel Allen Designs is a luxury residential design studio. Our founder, Daniel Sievers, spent over twenty years as a custom home builder before transitioning to full-time design. That construction background is not a credential we mention in passing — it's embedded in the way we draw.
We call it the Builder's Eye. It's the reason builders tell us our documents are easier to price and easier to build than typical residential drawings: fewer allowances, fewer RFIs, fewer surprises at framing. It's also the reason we can have an honest conversation with your builder during design development, because we've been on the other side of that table.
We design primarily for luxury single-family residences in Metro Atlanta — Buckhead, Sandy Springs, Johns Creek, Alpharetta, Milton, Roswell — and for clients nationwide. Our process runs from concept through permit-ready construction documents, with construction administration available to support your builder through the build.

Frequently Asked Questions
What is the difference between a licensed architect and a residential designer?
A licensed architect has completed an accredited degree, a supervised internship, and passed the multi-part Architect Registration Examination. They can apply a professional seal to construction documents in their licensed state. A residential designer produces the same deliverables — floor plans, elevations, sections, schedules, construction details — without that state license, which is legal for most single-family residential work across the Southeast. For most luxury custom homes in Georgia and neighboring states, homeowners have a legitimate choice between the two.
Do I need a licensed architect to build a custom home in Georgia?
In Georgia, no. O.C.G.A. § 43-4-14 exempts construction documents for one- and two-family residences and domestic outbuildings from the architect seal requirement, regardless of cost and with no square-footage cap. A qualified residential designer can produce permit-ready construction documents that Metro Atlanta building departments will accept. The seal requirement does apply to multi-family, mixed-use, and certain commercial building types. Confirm with your local building department if your project includes anything beyond a standard single-family residence.
Can a residential designer produce the same documents as an architect?
For residential design and construction documentation, yes. An experienced residential designer produces the same deliverables: floor plans, exterior elevations, building sections, roof plans, interior elevations, door and window schedules, finish specifications, and structural coordination drawings. The differences appear in licensure (designers cannot stamp drawings), scope (most architects work across building types; residential designers focus exclusively on residential), and depth of residential-specific experience. For projects that legally require an architect's seal, we coordinate with a licensed architect of record or refer the work entirely.
Do I hire a builder before or after a designer?
Hire your designer first. The design phase establishes what you are building; the builder's role is to construct what the designer documents. Hiring a builder before design is complete removes your ability to bid the project competitively and costs you leverage on the construction contract. The right sequence: hire designer, complete through construction documents, then bid to two or three qualified builders.
How are design fees and construction costs typically structured?
Residential designers typically charge 1.5% to 3.5% of construction cost for full-service new construction engagements, or on a phase-based flat fee for limited scopes. Licensed architects on residential projects generally run 6% to 12% of construction cost. Builders are paid through the construction contract — fixed-price, cost-plus, or guaranteed maximum price — with construction payments made as monthly draws against completed work. In Metro Atlanta, luxury custom home construction typically runs $350 to $600+ per square foot depending on finishes and complexity. Design fees generally represent 2% to 5% of total project cost; the remainder is construction.
What if I'm building outside Georgia?
State licensing exemptions vary. South Carolina, North Carolina, Florida, Tennessee, and Alabama all have residential exemptions for one- and two-family homes, but the specifics differ — particularly around multi-family thresholds, square-footage limits, and occupancy types. We've summarized the key statutes above. Always confirm with your local building department before signing a design contract, and consult an attorney if your project has mixed-use or commercial components.
