The simple roles: architect, designer, contractor
On most building projects, these roles work together—but they are not the same job.
An architect designs and coordinates building plans, especially when code, zoning, layout, and permitting details matter. A designer may help with visual design or planning, but licensing and the ability to stamp drawings varies by state and by what your project requires. A contractor builds the project based on approved drawings and permits.
If you’re adding space, changing a structure, or building new (including ADUs), you’ll usually want to start with the right design professional for permit-ready drawings—and then hire a contractor after plans are developed.
Architects: design, coordination, and permit-ready drawings (with state-specific stamping rules)
Architects typically handle the design process from early concept through construction documents. This includes thinking through how the building will work day-to-day, how it fits the site, and how it meets building codes.
In many states, only licensed architects (or licensed engineers for certain technical disciplines) can “stamp” drawings required for permits. “Stamping” generally means the professional is legally responsible for the work covered by the drawings, according to their license.
Rules vary by state and city. Some jurisdictions allow other licensed professionals to stamp certain plan types, but you’ll still want your drawings to match local permit requirements.
Designers: what they do well—and where licensing limits may apply
A designer can be a great fit for parts of a project, like interiors, space planning, or design direction. However, whether they can produce drawings that are acceptable for permitting depends on their training and—most importantly—whether they are legally allowed to stamp drawings in your location.
For example, an interior designer may help with finishes and layout, but an interior update often still needs code-compliant coordination (like structural changes, egress, fire safety, or accessibility). If your project affects walls, structural elements, plumbing/electrical scope, or site conditions, you may need a licensed architect or a licensed engineer depending on the work.
When you talk to a designer, ask directly: “Can you provide drawings that are permit-ready for my jurisdiction?” If the answer isn’t clear, that’s a sign you should confirm licensing and responsibilities before moving forward.
Contractors: construction, pricing, and buildability
Contractors translate approved plans into a built project. They handle budgeting, scheduling, construction means and methods, and coordinating subcontractors like framing, electrical, plumbing, HVAC, and roofing.
A contractor usually bids after drawings and specs are far enough along to estimate the work. If plans are still vague, costs can shift later because the scope is unclear (for example, window sizes, insulation details, or required fire separations).
Even with great design, a contractor can only build what the approved drawings require. That’s why permit-ready drawings and clear scope matter before you lock in a budget.
How to choose the right professional for your scope and budget
Start with your project category. New builds, structural changes, additions, ADUs, and many commercial projects usually need a licensed architect for permit-ready drawings. Smaller cosmetic projects may not.
Next, match the scope to deliverables. Ask what you’ll receive at each stage: concept options, schematic design, permit drawings, and (if applicable) construction documents. If “permit-ready” is part of your goal, confirm who will prepare and stamp (if required) the drawings for your local authority.
Budget timing matters too. Typical architect fees can range around 5%–15% of construction cost depending on complexity, deliverables, and local requirements. Fees are not one-size-fits-all, but having a realistic range helps you compare proposals. If you want a deeper breakdown, see Architect fees explained.
If you’re not sure who to start with, we can help. Studio Northing is a FREE service that connects you with a licensed architect for your project scope—so you can ask the right questions and move forward with confidence: Get matched.
- Confirm whether permit-ready drawings are required for your city/county and who can legally stamp in your area.
- Ask what deliverables you’ll get (concept, schematic, permit drawings, construction documents).
- Compare proposals for scope clarity, not just price—unclear scope can cost more later.
Questions to ask before you hire (so you don’t get stuck later)
Use these questions in your first call or consultation. They’re designed to clarify responsibility, process, and timing—especially when you’re new to the US permitting and construction system.
1) “What exactly will you deliver for my project?” You want named deliverables, not vague promises.
2) “Are the drawings intended to be permit-ready for my jurisdiction?” If needed, ask who will submit and stamp drawings (and what depends on local rules).
3) “How does the process work step-by-step, and what happens if the city requests changes?” Good professionals explain how revisions are handled and when costs could increase.
4) “How is your fee structured, and what’s included at each stage?” For many projects, fees are tied to stages. If you’d like guidance on typical structures, start with Architect fees explained.
5) “When can I expect permit submission and what documents do you need from me?” For example, surveys, existing plans, and site information can affect timelines.

In plain English
Architects, designers, and contractors each play different parts—know who can legally stamp permit drawings in your area, then match the right professional to your project scope using clear deliverables.
Always hire a licensed architect, and verify the state license yourself before work starts. General information, not architectural, engineering, or legal advice.
