Do You Need an Architect to Build a House? (2026)

Updated November 2026. This page used to be a checklist for choosing an architectural firm. Before that choice comes an earlier question many owners ask us: do you need an architect at all? The page now answers it with state law, then shows how to pick a firm if you do. Statutes and NCARB pages read November 13, 2026.

Often no, for a single-family house, but it depends on your state and your design. As of November 2026, Florida law says no one has to be an architect to plan a one- or two-family home, regardless of cost (Fla. Stat. 481.229). Texas and California have similar exemptions with limits. Engineers, codes and your building department may still require sealed drawings for parts of the job.

It feels like a new house must need an architect. In many states it doesn’t, at least not by law. Lots of homes go up from plans drawn by a home designer, a drafter or the builder’s own team. The real question is whether your plan, your lot and your budget need one.

Do you need an architect to build a house in your state?

Each state writes its own rule, and they differ in the details. Here are three large ones, from the statute text:

Building somewhere else? NCARB keeps a state-by-state licensing requirements tool, and your state board or building department can tell you what a permit needs. Call before you pay anyone for drawings.

Who can draw house plans if not an architect?

Where the law allows it, several people can.

• A home designer or drafter. Often cheaper and quick for simple layouts. Ask for permit sets they’ve had approved in your county.
• The builder’s design team. Common with semi-custom homes. Handy, but the plans may be tied to that builder.
• A licensed engineer. Needed for structural parts, foundations on poor soil or high-wind design, whoever draws the rest.
• You. Some owners draw their own plans for simple projects. Expect the building department to ask hard questions.

Whoever draws them, the plans still have to meet the building code. The rule only drops the license; it doesn’t lower the bar.

When is an architect worth hiring anyway?

Hire one when the design is hard. A steep or odd-shaped lot, a view you want to frame, a tight setback, a historic district, a big custom home or an unusual frame all gain from an architect’s training. So does a job where you want one person to run the engineers, the consultants and the builder.

Licensure is demanding. NCARB explains there is no national license: each of the 55 U.S. jurisdictions sets its own rules, which typically combine education, experience and an exam. In its 2026 report, NCARB says the number of licensed architects grew in 2025.

Do you need an architect for a home addition?

Usually not by law in the three states above, for a one- or two-family home. Florida’s exemption covers enlarging or altering those homes, and Texas covers them under the same section. In California, the woodframe and two-story limits still apply. What decides it in practice is the permit office: it may ask for structural details on new framing, which can mean an engineer.

For permits, lien papers and the cleanup after, see what to do during and after a renovation.

How do you choose an architectural firm?

Start with three to five firms. Ask neighbors who built or remodeled, ask local builders who they like working with, and look at projects you admire. A builder’s view is useful because they see how complete a firm’s drawings are.

Then match the firm to the job. Size and type should fit. A residential architectural firm that designs custom homes works very differently from one that does schools or warehouses. Ask for two or three past clients and call them: did the project stay close to budget, and would they hire the firm again? Then check the license with your state board. In Florida, the Board of Architecture and Interior Design regulates architecture businesses as well as individual architects.

NCARB’s guide to becoming an architect explains the path, and the 2026 NCARB by the Numbers report tracks the profession. Our post on how to choose an architect for your real estate project goes deeper on portfolios and communication.

How do architects charge, and what goes in the contract?

Three ways are common: a percentage of construction cost, a fixed fee for a defined scope, or hourly billing. Some firms mix them. Line proposals up by phase, from schematic design to construction documents to site visits during the build. The lowest proposal sometimes leaves out construction administration, which is where a lot of mistakes get caught.

Put it in writing before design starts. A good agreement lists the scope by phase, the fee and payment schedule, what counts as an extra, how many revisions are included, who owns the drawings and how either side can end it. AIA Contract Documents publishes standard owner-architect and residential agreements that many firms use as a base. Need marketing images before the house exists?

What about buying the land, and selling the finished home?

Many projects start with a lot. Our guides to getting a land loan and what to know before you buy land cover the money side. The Beycome buyer program has no upfront fee and is open to every buyer on properties listed by other agents (the commission credit can’t apply where no buyer-agent commission is offered, like most FSBO lots, or on homes listed by Beycome sellers). Beycome keeps 1% of the price, $1,499 minimum, and credits the rest at closing with lender approval. Rebate rules vary by state, and the credit isn’t offered in Alabama or Tennessee.

Buying or selling in Florida or Texas? Beycome Title handles the closing: $99 prepaid in Florida and $299 in Texas, and it also closes in Michigan, Ohio, Illinois and Indiana.

When the house is done, Beycome lists it on the major home search sites and the MLS within 2 business days of a complete questionnaire. A flat fee MLS listing starts at $99 in most states, with $0 due to Beycome at closing, in 17 states and DC. Read how to sell new construction before you set the price.
