It’s important to note that the following discussion of architectural fees is specific to Tulsa, Oklahoma and the South-Central region of the U.S. While fee structures may vary in other areas, this guide provides a breakdown of how architectural services are structured locally, including available service tiers and key budgeting considerations to help homeowners navigate their projects with confidence.
One of the most frequent questions homeowners ask when planning a residential project is: "How much will architectural services cost?" Whether designing a custom home, renovating an existing structure, or planning an addition, understanding how architectural fees are structured is key to making informed decisions.
A home is more than just a structure—it’s where you live, rest, connect, and create lasting memories. Unlike commercial buildings designed for business or public use, a home is deeply personal. It should reflect your lifestyle, support daily routines, and provide a comfortable, functional, and inspiring environment. Because of this, residential architecture extends beyond cost alone, incorporating design efficiency, aesthetics, usability, and long-term value.
This guide offers a clear breakdown of architectural fees, service tiers, and essential budgeting principles to help homeowners make informed decisions about the spaces they will live in and experience every day.
1. How Residential Architectural Fees Are Structured
Architectural fees for residential projects are typically hourly-based, ensuring flexibility and transparency in cost. While total fees typically do not exceed a percentage of construction costs, the final cost depends on the level of service required.
Service Tiers
Architectural services are divided into three tiers to match different project needs:
- Tier 1: Permit/Builder’s Drawings (Hourly, with a case-by-case cap)
- Tier 2: Enhanced Drawings & Interior Selections (Hourly, with a case-by-case cap)
- Tier 3: Comprehensive Drawings & Full Coordination (Hourly, typically not exceeding 15% of the cost of work)
This tiered structure ensures that homeowners receive the appropriate level of service while maintaining cost predictability and efficiency.
Hourly Rates
Architects and interior designers generally charge $100 to $250 per hour.
2. Understanding Residential Architectural Services
The range of architectural services varies based on project complexity. Whether you need basic permitting drawings or full-scale design coordination, services can generally categorized into three tiers to help homeowners select the best fit for their needs.
Tier 1: Permit/Builder’s Drawings (Hourly, case-by-case cap)
Designed for homeowners who need only the fundamental documentation required for obtaining permits and guiding construction, this tier includes:
- Cover Sheet
- Site Plan
- Foundation Plan
- Floor Plans
- Roof Plan
- Exterior Elevations (basic material indications)
- One Wall Section
Tier 2: Enhanced Drawings & Interior Selections (Hourly, case-by-case cap)
For homeowners seeking enhanced design detail and interior coordination, this tier includes Tier 1, plus:
- Lighting Plan
- Basic Electrical Plan
- Lighting & Plumbing Selections (itemized, not drawn)
- 3D Exterior Rendered Views
- Limited Interior Design: Mood Boards, Finish & Product Selections (itemized, not drawn)
Tier 3: Comprehensive Drawings & Full Coordination (Hourly, typically not exceeding 15% of the cost of work)
The most detailed service level, ideal for custom homes and high-end renovations, this tier offers fully integrated design solutions. It includes all Tier 2 services, plus:
- Fully Coordinated Exterior Elevations (materials + details)
- Complete Wall Sections & Unique Conditions
- Detailed Plan & Section Drawings (interior & exterior)
- Detailed Electrical Drawings
- Plumbing Plans
- Enlarged Floor Plans
- Fully Coordinated Schedules Integrated into Drawings
- 3D Interior Rendered Views

3. Construction Administration & Oversight
Architect's Fees for Construction Administration are generally hourly as required.
Beyond the design phase, architects offer construction administration services to oversee project execution. The level of involvement depends on the contractor’s skill, experience, and management capabilities. Some contractors require minimal support, while others need extensive coordination.
Construction Administration Services Include:
- On-Site Meetings with homeowners & contractors
- Site Observation Reports to document construction progress
- Reviewing Contractor Submittals for material compliance
- Responding to RFIs (Requests for Information) from the builder
- Certifying Payments to verify proper billing
- Conducting Punch List Reviews before project completion
- Issuing Certificates of Substantial Completion
Since construction oversight varies based on contractor efficiency, this phase remains hourly-based to allow flexibility in addressing project-specific needs.
4. Factors That Influence Architectural Fees
Several factors affect the total cost of architectural services:
Project Complexity
Homes with intricate features—such as vaulted ceilings, complex roof structures, historic restorations, or custom millwork—require more detailed planning, leading to increased fees.
Project Size
Larger homes require additional planning, but the tier-based fee structure ensures that costs remain proportional to the project’s scale.
Scope of Services
Choosing Tier 1 vs. Tier 3 significantly affects costs. More comprehensive service tiers demand additional design hours and consultant coordination.
Project Timeline
Compressed project timelines often necessitate overtime, faster design approvals, and quicker consultant collaboration, which can result in increased costs.
Owner’s Decision-Making Process
While architects anticipate design adjustments as part of the creative process, the number of revisions often depends on the homeowner’s ability to make timely and decisive choices.
- Clients who frequently revise or expand project scope will require additional architectural hours.
- Clear and efficient decision-making helps control costs and streamline the project timeline.
5. Architectural Fees: An Investment in Quality, Efficiency & Value
Hiring an architect isn’t just about getting drawings—it’s an investment in thoughtful design, long-term efficiency, and overall project success.
Maximize Functionality & Efficiency
A well-planned home enhances usability, minimizes wasted space, and improves energy performance, reducing future operational and maintenance costs.
Avoid Expensive Design Mistakes
Poorly conceived layouts and inefficient floor plans can create costly construction and usability issues. A well-designed home anticipates future needs and ensures long-term satisfaction.
Enhance Property Value
Homes with intelligent layouts, high-quality finishes, and architectural integrity tend to appreciate in value. Investing in great design benefits both everyday living and future resale potential.
6. Smart Strategies for Managing Architectural Fees
To ensure you get the most value from architectural services:
- Define Your Project Scope Early: The more clarity at the start, the fewer costly revisions later.
- Understand the Fee Structure: Choose a service tier that aligns with your project needs.
- Select the Right Service Tier: Choose a level of design appropriate for your budget & goals.
- Communicate Often: Regular check-ins with your architect prevent misunderstandings and budget overruns.
- Review Contracts Carefully: Ensure all fees, deliverables, and responsibilities are clearly outlined.
