A cross-border architectural practice — working on projects in both Mexico and the western United States — requires navigating two separate licensing systems that do not recognize each other. Understanding the requirements in Arizona, California, and Nevada is the first practical step for any architect or client managing a project that crosses the border.
The US Licensing Framework
Architecture in the United States is regulated at the state level. Each of the fifty states maintains its own licensing board and its own requirements for licensure. There is no federal architecture license. An architect licensed in Colorado is not automatically licensed in California or Arizona — each state requires separate application and approval.
The practical mechanism that allows architects to work across state lines is NCARB (National Council of Architectural Registration Boards) certification. An architect who obtains NCARB certification has documented their education, experience, and examination record in a portable format that most state boards accept as part of a reciprocal application. It does not eliminate the requirement to apply in each state, but it simplifies and accelerates the process significantly.
Arizona, California, and Nevada: Key Differences
Arizona is administered by the Arizona State Board of Technical Registration (AZBTR). Arizona participates in NCARB reciprocity, meaning an architect with NCARB certification who is licensed in another state can typically apply for Arizona licensure through a streamlined process. Arizona's requirements include the standard ARE passage and evidence of professional experience meeting the AXP (Architectural Experience Program) requirements.
California's licensing board (California Architects Board, CAB) is known for being more stringent than most states. California does not offer automatic reciprocity even for NCARB-certified architects. The CAB reviews each application individually and may require California-specific examination components. Architects practicing in the California market should plan for a longer licensure timeline than in Arizona or Nevada.
Nevada's State Board of Architecture, Interior Design and Residential Design accepts NCARB certification and offers reciprocal licensing that is generally straightforward for licensed architects from other states. Nevada's construction market — particularly in Las Vegas and Reno — includes a significant volume of hospitality and residential projects relevant to architects working in the Mexico-US corridor.
The Mexican Side of the Equation
In Mexico, architecture practice requires a cedula profesional issued by the Secretaria de Educacion Publica (SEP). This is the professional license that allows an architect to sign and seal construction documents submitted to Mexican authorities. A foreign architect — including one licensed in Arizona, California, or Nevada — cannot sign those documents without a Mexican cedula.
The practical approach for cross-border practice is a collaborative structure: a US-licensed architect handles the US side of any binational project, and a Mexican-licensed architect serves as architect of record on the Mexican side. Both bring full competency in their respective regulatory environment.
In MÉTODO, our studio has principals licensed in both Mexico and the United States, which allows us to manage projects on both sides of the border without needing an external compliance partner for routine permitting matters. This is unusual and is one of the specific capabilities we bring to clients who own or develop property in both countries.
What This Means for Clients
If you are a client with property in both Mexico and the US — common among families who maintain residences or develop projects in both markets — the licensing structure matters for how you select your architect.
An architect who is licensed only in Mexico cannot legally practice on your US-side project without a US-licensed collaborator. An architect who is licensed only in a US state cannot sign for your Mexican project without a Mexican partner. Both are workable arrangements, but they add coordination complexity.
An architecture firm with licensed professionals on both sides can manage the full scope of a binational project with fewer handoffs. Fewer handoffs mean fewer miscommunications, fewer duplicated efforts, and a more consistent design vision across both projects.
The ARE and What It Covers
The Architect Registration Examination (ARE) is the national professional examination required for architecture licensure in all US states. It consists of multiple divisions covering programming and analysis, project planning, building systems, construction and evaluation, and practice management. The full examination process typically takes one to three years to complete depending on preparation and scheduling.
Architects trained in Mexico's licenciatura en arquitectura programs (typically five years) who intend to seek US licensure should evaluate whether their education will be accepted by the relevant state board. NCARB provides a foreign credential evaluation service. The outcome varies by institution and program content.
Próximos pasos
If you are planning a project that involves sites or properties in both Mexico and the US, clarifying the licensing requirements early prevents delays later. The architect selection conversation should include a direct discussion of who will serve as architect of record on each side of the border.
