How much does an architect cost for a renovation?

Two numbers for two different jobs

Angi's figure is an average across 1,642 projects reported by its own contractors in 2026, with a typical range of $2,189 to $11,550, small jobs from about $550 and large engagements above $50,000 (Angi, marketplace data read from search-result text, not page-verified). An average like that is pulled down by the most common job on a marketplace: a set of drawings for a permit. Angi's separate guide puts drafting blueprints at $1,731 on average, most between $815 and $2,710 (Angi, 2026, same caveat).

The percentage ranges describe something else: an architect who designs the project, produces the drawings, helps with permits and pricing, and stays involved through construction. On a $150,000 remodel, 15 to 20% is $22,500 to $30,000. That is arithmetic on AIA's range, not a quote, and it is a different service from the $1,731 set of drawings.

Why do remodels sit higher than new construction as a percentage? Existing buildings have to be measured, surveyed and worked around. There are more unknowns per dollar of construction, and the drawings have to deal with what is already there.

The four ways architects charge

AIA's consumer guidance says compensation is often based on time, a stipulated sum, a percentage of the cost of the work, the project's square footage, or a combination (AIA, How to work with an architect, read 10 October 2026).

• Hourly. AIA calls this the simplest and perhaps most widely used structure at small firms, usually invoiced monthly and often with a cap. It suits the early stage, when nobody yet knows how big the project is.
• A fixed sum. AIA says this is not recommended until you and the architect have a tightly defined scope, and that some architects charge a separate fee to create that scope first. Once the scope exists, a fixed fee gives you certainty.
• A percentage of construction cost. The ranges above. The fee rises if the budget rises, so ask how it is calculated when the budget moves, and whether it follows the estimate or the final cost.
• A rate per square foot, or a combination: hourly to define the project, then a fixed fee to deliver it. Ask what area counts.

When you pay: by phase

Most architects bill as the work moves through phases. The names vary, but a common sequence runs from concept design, through developed design and construction drawings, to permit and pricing, and then construction. The California Architects Board recommends that your contract set approval points between phases, a payment schedule, the amount of any retainer and how it is applied, and what is owed if the agreement ends early (CAB Consumer's Guide, read 10 October 2026).

1. At signing. Some architects ask for a retainer. The CAB tells homeowners to be wary of excessive advances or retainer fees to begin services. A retainer should be modest and credited against later invoices.
2. During design. Hourly work is usually invoiced monthly (AIA). Fixed fees are usually split across the phases, with an invoice at each approval point.
3. At permit and pricing. The drawings are complete, and this is often the largest invoice.
4. During construction. If the architect visits site and administers the contract, that is billed as the build goes on. Ask how often they will visit and whether it is included (CAB).
5. At the end. The CAB's advice is to make the final payment only when the services are complete.

What the fee does not include

The California Architects Board gives homeowners a list of fee questions to ask. Each one marks something that is often outside the basic fee (CAB Consumer's Guide, read 10 October 2026).

• Consultants. Structural, mechanical, electrical, plumbing, geotechnical, interior design and landscape work are often separate contracts. Ask which are included in basic services.
• Permit and government fees. Paid to the city, not the architect, and on top.
• Additional services. Anything outside the agreed scope, priced hourly or by agreement.
• Reimbursables. Printing, travel and similar expenses, charged at cost or with a mark-up.
• Redesign to meet the budget. The CAB's question is direct: will there be a charge for redesign if it is necessary to meet the construction budget? Get the answer in writing.
• Changes required by the building department, and changes you or the contractor ask for. Each should have a stated price basis.

Where the fee earns its keep

Of the renovating homeowners who set a budget in 2025, 37% exceeded it, and the reasons Houzz recorded were higher-than-expected product and service costs (52%), higher-end materials (35%), unanticipated complexity (32%), scope or design changes (31%) and construction issues (22%) (Houzz, 8 Home Remodeling Trends to Watch in 2026). Three of those are what a design phase is meant to settle before anyone orders materials. Only 8% of renovating homeowners hired an architect that year (Houzz, same study). A fee buys fewer surprises, not none.

Drawings only, and the stamp that does not exist

“How much does an architect charge to stamp drawings” is a search people make (Google autocomplete, US, 10 October 2026). A stamp is not a product. The California Architects Board lists signing someone else's plans among the grounds for disciplining an architect (CAB Consumer's Guide). An architect who puts their licence on drawings has to have prepared or properly reviewed them, and that review is paid work.

Drawings-only is a real service: measured drawings of your house, or a permit set for a defined, simple scope. Angi's 2026 marketplace figure for drafting blueprints, $1,731 on average, read from search results, is the scale of that work. It does not include designing the project, or anyone being on your side during construction.

Questions to ask before you agree a fee

• How is the fee calculated, and what does it cover? (CAB Consumer's Guide)
• Are the consultants' fees inside basic services or on top? (CAB)
• What permit and government fees should I expect? (CAB)
• How are additional services and reimbursables priced? (CAB)
• Will there be a charge for redesign to meet the budget? (CAB)
• How are changes required by the building department, by me, or by the contractor priced? (CAB)
• What fee should I expect for this project, and what happens to it if the scope changes? (AIA, Before you begin your project, 18 December 2024)
