Architect Fees for a Home Remodel, Addition, or New House
Architect fees are not a standard percentage or a universal “plans” price. The useful comparison is the amount of professional work you receive: phases, drawings, meetings, consultants, revisions, permit support, and construction involvement.
What an architect may be doing
Depending on the agreement, residential architectural services can include programming, site and existing-condition review, schematic design, design development, construction documents, bidding or procurement support, and construction-phase administration. AIA describes schematic design as establishing goals, requirements, relationships, and preliminary cost; later phases add detail for pricing and construction. The agreement controls the actual deliverables.
An architect may coordinate structural, mechanical, electrical, plumbing, energy, civil, or specialty consultants, but consultant fees may be separate. Ask whether the proposal includes those consultants or merely coordinates them.
Common ways fees are structured
You may see a stipulated sum, hourly billing, a percentage tied to a stated cost basis, or a combination by phase. A percentage is meaningful only when you know whether it applies to an owner budget, construction cost, a defined portion of the work, or something else. AIA’s current compensation discussion emphasizes that the parties should define the basis and how it changes as the budget develops.
Canadian homeowners may encounter the Royal Architectural Institute of Canada’s scope-first fee framework. It is a tool for defining services and fees, not a mandatory residential tariff or a quote for your project. U.S. and Canadian fee observations should remain separate; a currency conversion does not create comparable market evidence.
What makes a fee higher or lower?
- Existing-building uncertainty: Hidden structure, incomplete drawings, and irregular conditions increase field work and coordination.
- Project complexity: An addition, change of use, historic property, or major structural alteration usually demands more than a simple interior layout.
- Design depth: Concept images, permit drawings, and construction-ready documents are different products.
- Consultant coordination: Structural, MEP, civil, energy, or specialty input adds time and fees.
- Client decisions and revisions: A defined number of review rounds is easier to price than open-ended changes.
- Approval path: Zoning, heritage, variance, or multiple permit authorities can add documentation and responses.
- Construction-phase service: Site observations, submittal review, RFIs, payment review, punch-list work, and closeout may be included, limited, or excluded.
Compare proposals by scope
Ask each architect to state:
- The phases included and the point at which services stop.
- The drawings, specifications, models, schedules, and calculations delivered.
- The assumptions about project size, construction budget, and site information.
- The number of meetings, site visits, bid packages, and revision rounds.
- Consultant responsibilities and whether consultant fees are included.
- Permit submission and response responsibilities.
- Construction administration activities, frequency, and exclusions.
- Reimbursable expenses, travel, taxes, and additional-service rates.
- What happens if the project pauses, changes scope, or is not built.
Do not select a proposal solely because its percentage is lower. A lower fee can reflect fewer phases, less documentation, fewer revisions, or no construction support rather than better value.
Remodel, addition, or new house?
A remodel can be cheaper than new construction in some cases, but existing conditions create uncertainty and coordination work. An addition may combine site, zoning, foundation, structural, envelope, and utility decisions. A new house may have more area to document but fewer unknown existing conditions. There is no reliable universal ordering because location, scope, and professional responsibility matter more than the label.
Whether an architect is required, whether drawings must be sealed, and which professional may provide them are jurisdiction- and project-specific. Confirm those questions with the local authority and the licensed professional before assuming a cheaper service is legally interchangeable.
When construction administration is separate
Design documents do not automatically include construction-phase support. If the contractor asks for clarification, proposes a substitution, or submits a payment application, the person who responds may be working under a separate service scope. Read architect construction administration fees when the question is what happens after design is finished.
The right fee is the one you can explain line by line. If you cannot tell which decision, deliverable, or risk each charge addresses, the proposal is not yet specific enough to compare.
