You got a quote for permit drawings. Maybe it was $1,200. Maybe $6,000. And you have no real way to tell if that's fair because every firm hides pricing behind "contact us for a quote," and every forum thread on the subject dead-ends at "it depends." This is the page that actually gives you numbers. Here's what permit drawings cost, why the ranges are so wide, and how to tell a fair quote from a bad one.
How much do permit drawings cost? The short answer
Most residential permit drawings run somewhere between $500 and $8,000, depending on the project. A small remodel sits at the low end. An ADU or a new custom home sits at the high end. Commercial tenant improvements are their own animal and can run higher.
Here's the pricing logic underneath that range. A drafter typically charges $50–$150/hour or $0.25–$0.75 per square foot. An architect typically charges $100–$250/hour or 5–15% of construction cost. If all you need is the permit set the drawings that get your project approved you're paying the lower end. If you need full architectural design plus construction oversight, you're paying the upper end. Same building, very different scope, very different bill.
That's the honest headline. Now let's break it down so you can walk into your quote conversation knowing exactly what you're paying for.
What's actually in a permit set?
Quick but important, because this is where most of the confusion starts. A permit set is the production document the drawings a plan reviewer needs to approve your project. It is not the full architectural design package. That distinction is a big reason two quotes can look so different.
A typical residential permit set includes:
Site plan your property, the structure, setbacks, and what's changing
Floor plans existing and proposed layouts, dimensioned
Elevations exterior views of each affected side
Sections cutaway views showing how the building is built
Roof plan slopes, drainage, framing direction
Foundation plan especially critical in regions with expansive clay soil
MEP notes mechanical, electrical, and plumbing coordination
What a permit set is not: hours of design exploration, 3D renderings, material boards, or someone managing your contractor. Those are real services. They're just not what "permit drawings" means. When a quote balloons, it's often because it quietly includes design work you may not need or because it's missing pieces you'll get billed for later.

How much do permit drawings cost by project type?
This is the part nobody publishes. Ranges below are typical US figures for the drawings themselves (permit set preparation), not construction. Structural engineering is usually separate more on that below. Geography moves these numbers: dense metros and jurisdictions with heavy plan-review requirements cost more.
Project typeTypical range (drawings)What's usually includedMain variableSmall bathroom / kitchen remodel$500 – $2,000Floor plan, basic elevations, notesWhether walls or plumbing moveGarage conversion to living space$1,500 – $4,000Floor plan, elevations, egress, insulation / energy notes, light structuralNew openings and structural workRoom addition / bump-out$2,000 – $5,000+Site plan, floor plans, elevations, sections, foundationSize and roof tie-in complexityADU (accessory dwelling unit)$3,000 – $8,000+Full set: site, floor, elevations, sections, foundation, MEP notesIt's a small house everything scalesNew custom home (full CD set)$5,000 – $15,000+Complete construction document setSize, custom detailing, engineeringCommercial tenant improvement$3,000 – $25,000+Varies by use, occupancy, and code scopeAccessibility, fire / life safety, MEP
A few notes on the ranges that matter most for the work we quote:
Garage conversions look simple and often aren't. The drawing itself is straightforward, but the second you add a bedroom, cut in an egress window, or convert the space into a dwelling, you're into structural, energy, and sometimes fire separation requirements. That's what moves a $1,500 job to $4,000 not padding, just scope.
ADUs are priced like the small homes they are. A permit set for an ADU carries nearly everything a house does: site plan, full floor plans, elevations, sections, foundation design, and MEP coordination. Mid to upper range is normal, and a suspiciously cheap ADU quote usually means something's about to be billed separately.
Commercial tenant improvements are why that last row spans so wide. A cosmetic office refresh and a restaurant build-out are both "TI," but one needs a floor plan and the other needs accessibility compliance, grease trap plumbing, fire rated assemblies, mechanical loads, and often a licensed stamp. In most jurisdictions commercial work also requires an architect's or engineer's seal, which lifts the floor on price. When someone quotes commercial TI, the number tells you almost nothing until you know the use and the code scope behind it.
What drives the price up beyond the base quote?
Here's where homeowners get surprised. The base drafting fee is rarely the whole bill. These add ons are legitimate but if a quote doesn't mention them, ask, because you'll meet them eventually.
Structural engineering. Often required and usually not included in a drafting quote. Budget a separate fee (commonly a few hundred to a couple thousand dollars) whenever you're adding load, cutting openings, or building new foundation which, in expansive soil regions, is most of the time.
Revisions. Most firms include a set number of revision rounds. Go past it and you're billed hourly. This single line item is where "cheap" quotes quietly get expensive.
Expedited turnaround. Need it in a week instead of three? That's a rush fee at most shops.
As-built survey. If no accurate existing drawings or property survey exist, someone has to measure and document what's there first. That's an added cost, not a given.
MEP coordination drawings. Simple projects fold these into notes. Bigger or commercial projects need dedicated mechanical, electrical, and plumbing sheets.
Permit filing and follow-up. Some firms file with the city and manage plan check comments for you. Some hand you the PDF and wish you luck. Both are valid just know which you're buying.
Resubmittals. If plan check kicks the set back, corrections and resubmittal may or may not be included. Ask before you sign, not after.
None of these are scams. They're the difference between a price for drawings and a price for getting your project through permitting. The trick is knowing which quote you're holding.
Drafter vs architect: what the price difference actually reflects
A drafter quoting $0.30/sqft and an architect quoting $2/sqft can both be doing honest, legitimate work. The gap isn't quality of linework. It's scope, liability, and licensing.
An architect is licensed and can stamp drawings, legally certifying code compliance and carrying the professional liability that comes with it. That's real value on projects that require it: new homes, complex builds, and most commercial work. A drafter can't stamp, which is exactly why they cost less and why they're the right, fully sufficient choice for the large share of residential projects that don't need a seal.
So a cheaper drafter isn't cutting corners, and a pricier architect isn't gouging you. They're selling different things. Which one your project actually requires is a separate question worth getting right before you spend a dollar we break it down in Draftsman vs Architect: Which One Do You Actually Need?
How do I know if my quote is fair?
Price alone won't tell you. Scope will. Before you sign anything, ask these five questions the answers separate a real quote from a number pulled out of the air.
What's included in this fee? Drawings only? Revisions? Permit filing? Get it itemized.
Does this include structural engineering, or is that separate? This is the most common hidden cost. Nail it down up front.
How many revision rounds are included? And what's the hourly rate once you exceed them?
If the permit gets rejected, are corrections included? Plan check comments are normal. Find out who pays to address them.
What's the turnaround time? And is there a rush fee if you need it faster?
A firm that answers these clearly and in writing is a firm you can trust with the job. A firm that gets vague when you ask is telling you something. Print this list, or send it as is to every quote you're comparing it's the fastest way to make wildly different numbers actually comparable.
Red flags in a permit drawing quote
Keep an eye out for these. Any one of them is worth a second conversation:
Vague scope with no itemization. "Permit drawings $2,500" and nothing else. What's in it?
No revision policy. If they won't put revision terms in writing, expect surprise invoices.
A rock bottom price with zero mention of code or jurisdiction research. Cheap drawings that ignore your city's requirements cost more than expensive ones that don't you pay in rejected submittals and delays.
No mention of local code compliance or who handles resubmittals. If the plan check fails, you want to already know whose problem that is.
FAQ
How much do architectural drawings cost for a new home?
For a full construction document set, expect roughly $5,000 $15,000 or more from a drafter or designer, driven by size and custom detailing. If you hire an architect for full services, pricing usually shifts to 5–15% of construction cost, which on a larger home is significantly more. What you're paying for at the high end is design and oversight, not just drawings.
Is a drafter cheaper than an architect for permit drawings?
Yes, usually noticeably cheaper a drafter runs $50–$150/hour versus $100–$250/hour for an architect. That reflects licensing and liability, not drawing quality. For most residential projects that don't require a stamped seal, a drafter's permit set is completely sufficient.
What is included in a permit set?
Typically a site plan, floor plans, elevations, sections, a roof plan, a foundation plan, and MEP coordination notes the drawings a plan reviewer needs to approve the work. It does not include full design exploration, renderings, or contractor management. That's the line between permit set preparation cost and full architectural design.
How much does a permit drawing cost for an ADU?
Usually $3,000–$8,000 or more for the drawings, because an ADU is a complete small dwelling and the set includes nearly everything a house does. Structural engineering and any required survey are often separate. Local energy and code requirements can push it higher.
Why are my permit drawing quotes so different from each other?
Almost always scope, not overcharging. One quote may be drawings only while another includes revisions, structural coordination, and permit filing. Use the five questions above to line them up on equal footing once you do, the "expensive" quote is often the honest one.
