NAICS Code for Architecture and Design Services
Federal architecture and design contracting covers building design, landscape architecture, interior design, graphic design, and specialized design services across federal construction, facilities, and program communications work. NAICS selection matters because design disciplines have distinct codes with very different size standards, and misclassification routes you to the wrong competition pool.
Primary NAICS codes for architecture and design
541310: Architectural Services ($12.5M size standard) Building architecture, building design services. The primary NAICS for architecture firms providing building design for federal construction.
541320: Landscape Architectural Services ($9.5M size standard) Landscape design and outdoor space planning services.
541330: Engineering Services ($25.5M, up to $47M) Engineering design services. Firms providing engineering alongside architecture often primary here because size standard is higher.
541340: Drafting Services ($9.5M size standard) Technical drafting and drawing services. Narrow NAICS for firms specializing in drafting without full design services.
541410: Interior Design Services ($9M size standard) Interior design services for commercial and federal spaces.
541430: Graphic Design Services ($9M size standard) Graphic design, visual communications, and creative design services. Different from architectural design.
541490: Other Specialized Design Services ($17M size standard) Specialized design services not classified elsewhere — industrial design, fashion design, specialized technical design.
Secondary NAICS codes to consider
541350: Building Inspection Services ($12.5M) For design firms that also provide commissioning or inspection services.
541360: Geophysical Surveying and Mapping ($19M) For design firms doing subsurface investigation as part of design services.
541370: Surveying and Mapping (except Geophysical) ($19M) For land surveying and mapping services adjacent to design work.
541922: Commercial Photography ($9.5M) For design firms with significant photography practice.
Which code should be your primary
Architecture firms (building design) primary under 541310. This is the default and correct for most federal architecture work.
Landscape architecture firms primary under 541320.
Multi-discipline firms (architecture + engineering) face a strategic choice. 541310 at $12.5M is significantly lower than 541330 at $25.5M-47M. Many integrated A/E firms primary under 541330 engineering when the work mix supports it, because the size standard gives much more runway.
Interior design firms primary under 541410.
Graphic design firms primary under 541430.
Specialized design (industrial, exhibit, custom design) — 541490.
Size standard considerations
Design NAICS have some of the lowest size standards in professional services. 541310 at $12.5M, 541410 at $9M, 541430 at $9M, 541922 at $9.5M. Firms graduate out of small business status quickly.
Strategic considerations:
- Multi-discipline firms can often legitimately primary under 541330 engineering ($25.5M-47M) rather than 541310 architecture ($12.5M), extending small business runway significantly
- Architecture firms considering 541330 should confirm the work mix supports engineering primary — misclassification triggers size protests
- Design firms with strong graphic design practice alongside architecture can pursue 541430 for communication work and 541310 for building work as secondary NAICS
Federal demand snapshot
GSA Public Buildings Service (PBS) is a major federal architecture buyer for federal building design, renovation, and space planning.
Army Corps of Engineers contracts extensive A/E services for military construction (MILCON), civil works, and international engineering support.
VA contracts architecture and interior design for medical center construction, modernization, and renovation. Medical environment design is a distinct specialty with consistent VA demand.
NPS (National Park Service) and other Interior Department agencies contract landscape architecture and visitor facility design.
DoD service branches contract A/E services for installation development, family housing, and MILCON projects.
Smaller agencies contract interior design and graphic design for office build-outs and program communications.
Set-aside patterns at design NAICS
Design services see consistent small business set-aside activity.
SDVOSB set-asides are common in A/E work, particularly at VA medical center renovation and Army Corps engineering projects.
8(a) set-asides drive significant design contracting volume.
WOSB set-asides appear — several design NAICS are on the eligible list.
HUBZone set-asides see design activity, particularly for projects in HUBZone-located facilities.
Common entry paths
1. A/E IDIQ positioning at Army Corps and VA. Army Corps of Engineers runs several major A/E IDIQs for different regions and disciplines. VA maintains A/E IDIQs for medical center work. Getting on these is substantial capture investment but opens significant volume.
2. GSA Architect-Engineer Schedule. GSA's MAS includes A/E services SINs. Schedule positioning is a broader-access path than individual IDIQs.
3. Specialization in building types. Healthcare design, judicial facility design, museum/cultural facility design, secure facility design — federal buyers value specialists with demonstrated building type expertise.
4. Teaming on MILCON projects. Military Construction at major installations typically includes A/E services through integrated prime contracts. Subcontracting to primes on MILCON is a path to past performance.
5. Graphic design via GSA PSS. Federal graphic design needs are spread across agencies. GSA Professional Services Schedule with 541430 SIN is the primary accessibility vehicle.
Common mistakes at design NAICS
Commercial design aesthetic mismatched to federal. Federal facilities have specific functional requirements, security considerations, 508 accessibility for physical space, historic preservation constraints, and sustainability standards. Commercial design sensibilities don't translate directly.
Missing Brooks Act considerations. A/E services at federal agencies are typically contracted under the Brooks Architect-Engineer Act, which is qualifications-based selection rather than price-based. Federal A/E proposals emphasize qualifications over pricing differently than commercial work.
Underestimating submittal and review cycles. Federal A/E projects have extensive review cycles (30/60/90/100% design reviews, stakeholder reviews, code reviews). Schedule realistically.
Ignoring sustainability and LEED requirements. Most federal construction requires specific sustainability performance (LEED Silver or higher, Energy Star, Federal Building Personnel Training Act requirements). Budget the sustainability design expertise.
