nope. varies greatly. find out before you start how much it will be and work in the budget.

Thank you! I have original drawings and doing a renovation project -finishing my basement into an apartment and some changes to rooms in the house

The cost for a licensed architect to produce construction plans is generally proportional to the scope of work. In our area, independent architect's fees are typically 7% to 8% of construction cost to produce a "biddable" set of plans for new construction projects and 12% of the cost for a remodel.

for new build ours were more like 3-4%. Which puts it way closer to 12k than your other numbers even for a smaller house. Definitely a fair amount of money but necessary in my opinion.

the type/amount of work an architect can do may also vary. Some are project managers of sorts and can oversee the construction . That can cost more. others just do the drawings. Ours was more the latter type. It seems that you are asking just for drawings costs and not for anything else, like preparing applications, board hearings, or oversight?

"Is there an average cost for architect drawings?"

No. It would be like averaging fruit. Every project is different. Find a few architects that you like the work they do and you feel you could work well with, and have them each give you an estimate of what it would cost for them to provide defined architectural services for your project.

The time required to design and oversee renovation work is so unpredictable that I provide an hourly rate and a budget range. Fees from start to finish of a project are usually between 3 and 6% of construction cost but I'm in an expensive construction cost area..

On the other hand, renovations that don't require moving exterior walls and foundations have limited options so things don't often get out of hand. But I've had clients who were so slow to approve a final design that their family got larger and we had to start again.

The cost of architect rural drawings and support will always be less than the cost of mistakes and assumptions of service and skill when dealing with a drafter employed by a builder.
