Remodel drawings without an architect: what is legal (by state, general)
In most states you do not need an architect to draw a remodel of a single family house. The exemptions are real but narrow, they differ by state, and a local building official can still ask for a licensed professional. Here is how the rules are built and what eight large states say.
Not legal advice. This is a general summary of statutes we read on 2026-10-08. Laws change and local building departments add their own requirements. Before you rely on any exemption, confirm it with your building department or a licensed professional in your state.
How the rules work
Every state licenses architects and engineers, and each licensing law says which buildings require a licensed professional to prepare the plans. Almost every state then carves out exemptions, and the biggest one usually covers one and two family houses. Inside an exemption, anyone may prepare the drawings: the owner, a contractor or a building designer.
Three separate questions decide whether your drawings need a stamp:
- The building type. A detached house is usually exempt. A condo unit in a larger building often is not.
- The work. Non-structural interior changes are the easiest case. Removing a bearing wall, adding a story or changing the structure brings in engineering, even in an exempt house.
- The local building official. Even where state law exempts a house, the official can require a licensed professional for unusual construction.
What eight states say

| State | Exempt residential work (summary) | Watch out for | Source |
|---|---|---|---|
| California | Single family woodframe dwellings up to two stories plus basement; multiple dwellings up to four units of woodframe, two stories | The building official may require an architect or engineer if any part deviates from conventional light wood frame construction. Section 5538 is commonly read as also covering nonstructural interior alterations; confirm locally. | Bus. and Prof. Code 5537 |
| Texas | Single family and dual family dwellings and their associated buildings | An unlicensed preparer may not call themselves an architect or architectural designer | Occ. Code 1051.606 |
| Florida | One and two family residences and townhouses up to three stories, and domestic outbuildings, regardless of cost | A condo unit in a larger building is not a one or two family residence | F.S. 481.229 |
| New York | Residence buildings of 1,500 sq ft gross or less; certain alterations up to $20,000 ($10,000 in New York City) that do not affect structure or public safety | Larger houses and many NYC filings need a registered architect or engineer | NYSED guidance, NYC DOB |
| Washington | Residential buildings up to four dwelling units, plus garages and sheds, regardless of size | Local officials can still require engineering for structure | RCW 18.08.410 |
| Illinois | Detached single family homes on a single lot; two family woodframe buildings up to two stories plus basement | Multifamily buildings, including condo units, are not exempt; interior changes affecting life safety or structure are not exempt. Chicago practice is stricter. | 225 ILCS 305/3 |
| Georgia | One and two family residences and domestic outbuildings, regardless of cost | Condo units in larger buildings are not covered | O.C.G.A. 43-4-14 |
| North Carolina | Family residences up to eight attached units, each with its own exit at grade | Stacked flats without a grade level exit per unit are not exempt | G.S. 83A-13 |
Other states follow the same pattern with their own limits. Search for your state's architecture practice act and look for a section titled exemptions or exceptions, then call your building department.
What is almost always outside the exemption
- Structural changes. Removing or cutting a bearing wall, new beams or headers beyond standard span tables, foundation work and additions usually need an engineer's calculation or stamp, even in an exempt house. The International Residential Code requires engineered design for elements beyond its prescriptive limits (section R301).
- Condos and apartments in larger buildings, where both the state law and the building's association commonly require a licensed professional.
- New dwelling units such as ADUs, which bring in zoning, fire separation and often state specific rules.
- Commercial or mixed use buildings, which follow different thresholds entirely.
What "without an architect" looks like in practice
A typical non-structural remodel of a detached house, such as a kitchen relayout or a bathroom gut without wall removal, can usually go to the permit counter with drawings prepared by the owner, the contractor or a drafting service. The set normally includes existing and proposed plans, demolition, electrical and plumbing sheets. Our article do I need drawings for a kitchen remodel permit lists the sheets.
If the job crosses into structure, the common pattern is a split: a drafter prepares the plans, and a licensed engineer designs and stamps only the structural item, for example a beam letter. That is usually cheaper than a full architect's set, but ask your building department whether it accepts that split.
Honest titles matter
Several states restrict the words "architect", "architectural" and "architecture" to licensed professionals. An unlicensed drafter should describe the work as drafting or building design and never imply a license. If someone offers to "get your plans stamped" without telling you which licensed professional reviewed them, walk away.
How we handle it
We prepare drawings only for work that sits inside these exemptions: non-structural remodels of detached one and two family houses. We do not stamp drawings and we are not architects or engineers. If your project needs a licensed professional, we will tell you at intake rather than after you pay. See permit-ready drawings for the scope, and as-built drawings if you only need the existing house drawn.
