A licensed architect typically charges 5 to 20 percent of construction cost to design a new home, according to HomeAdvisor. On a $500,000 build, that is $25,000 to $100,000. A residential home designer usually costs far less, with custom house plans running about $1 to $10 per square foot, according to Fixr. In Oklahoma, a home of one or two stories generally does not require a licensed architect.
That gap is large enough to change a budget, so it is worth knowing what each professional does, what the law requires, and when paying more makes sense.
What is the difference between a home designer and an architect?
An architect holds a state license to practice architecture. That license takes a professional degree, years of supervised experience, and a multi-part exam. Architects design every kind of building, from houses to hospitals, and in Oklahoma only a licensed architect may use the title.
A home designer, also called a building designer, specializes in residential work. Designers are not licensed as architects, so they cannot call themselves architects. Many hold a professional credential instead. The American Institute of Building Design created the Certified Professional Building Designer (CPBD) credential, which requires more than six years of work experience, submitted work samples, and an exam.
The practical difference for a homeowner is focus. An architect is trained across all building types. A good home designer has spent a career on houses: how families use them, how builders build them, and what they cost.
Do you need an architect to design a house in Oklahoma?
Usually not. Oklahoma's architecture law lists which building types must be designed by a licensed architect. According to the Oklahoma Board of Architects, residential buildings of one or two stories in the residential use groups it lists can be designed by either an architect or someone who is not licensed. Above two stories, an architect is required.
The Board adds an important caveat: local or state authorities can require an architect even where state law does not. Some building departments also require a licensed engineer to stamp structural drawings. Call your city or county before you hire anyone, and ask what it needs to issue a permit.
How much does an architect charge to design a house?
Architects bill in several ways. HomeAdvisor reports these national ranges:
|
Billing method |
Typical range |
|---|---|
|
Percentage of construction cost |
5% to 20% |
|
Hourly |
$125 to $250 per hour |
|
Per square foot |
$2 to $15 |

A percentage fee often covers more than drawings. It may include site visits and construction administration, where the architect reviews the builder's work against the plans. Ask exactly which phases a fee includes before you compare quotes.
How much does a home designer charge?
Home designers and drafters usually bill by the square foot or a flat fee. Fixr puts the average cost to draft house plans at $1,000 to $6,000, with these ranges by plan type:
|
Plan type |
Typical cost per square foot |
|---|---|
|
Stock plans |
$0.35 to $0.75 |
|
Modified stock or semi-custom plans |
$0.50 to $1 |
|
Custom plans |
$1 to $10 |
Source: Fixr, accessed October 2026.
The spread inside the custom range is about detail and service. A basic drafting job and a full custom design with 3D modeling, multiple revision rounds, and a builder-ready construction set both count as "custom plans." You can browse our stock plans, and our post on stock plans vs custom design explains when each makes sense.
What does each cost on a 2,500-square-foot home?
Using the $500,000 example from our post on custom home costs in Oklahoma City, here is how the national ranges compare. These are illustrations, not quotes.
|
Professional and method |
Design fee on a 2,500 sq ft, $500,000 home |
|---|---|
|
Architect, 5% to 20% of construction |
$25,000 to $100,000 |
|
Architect, $2 to $15 per sq ft |
$5,000 to $37,500 |
|
Home designer, custom plans at $1 to $10 per sq ft |
$2,500 to $25,000 |
What matters is what the fee buys, and our post on what a complete set of house plans includes shows what to look for. A cheaper plan set that leaves your builder guessing can cost more in change orders than it saved in design fees. Our guide to how much house you can afford to build helps you set the overall budget first.
When does hiring an architect make sense?
An architect is the right call when:
- The building is taller than two stories, or your jurisdiction requires an architect
- The project includes commercial space, or will be used for something other than a private home
- You want the same professional administering construction under a formal contract
- The site or structure is unusual enough to need extensive coordination with engineers
A home designer is often the stronger value for a one- or two-story custom home, a barndominium, or a modern farmhouse, where residential experience matters more than a license to design any building type.
How do you choose the right designer for your home?
Whoever you hire, ask these questions first:
- Will I see the home in 3D before it is built?
- Can any qualified builder price and build from these plans?
- How many revision rounds are included?
- Will you help me understand what the design will cost to build?
- What happens after the plans are done?
Then check credentials. You can look up an architect's license on the Oklahoma Board of Architects website, and you can verify a designer's CPBD status with the National Council of Building Designer Certification.
We model every home we design in 3D, so you can walk through it room by room before a builder ever prices it. Book a design consultation and we will walk you through what a custom design includes and what it costs.
Frequently asked questions
Is a home designer cheaper than an architect?
Usually, yes. HomeAdvisor puts architects at 5 to 20 percent of construction cost. Fixr puts custom house plans from designers and drafters at about $1 to $10 per square foot. On a $500,000 home, that difference can be tens of thousands of dollars.
Do I need an architect to build a house in Oklahoma?
Generally not for a one- or two-story home. The Oklahoma Board of Architects says residential buildings of that height in its listed use groups can be designed by an unlicensed individual or an architect. Local authorities can still require one, so check with your building department.
How much does an architect charge to design a house?
HomeAdvisor reports 5 to 20 percent of construction cost, $125 to $250 per hour, or $2 to $15 per square foot. Percentage fees often include construction administration, so compare what each quote covers.
What is a Certified Professional Building Designer?
A CPBD is a home designer certified by the National Council of Building Designer Certification, part of the American Institute of Building Design. Certification requires more than six years of experience, work samples, and an exam.
Can a home designer's plans get a building permit?
Yes, when the home falls within what state and local rules allow a non-architect to design. Some building departments require an engineer's stamp on structural drawings, so ask what your jurisdiction needs before you submit.
