A straight answer to "how much does a site plan cost" in 2026: anywhere from $35 to $25,000 — depending on who draws it, what your county wants, and how fast you need it. For most homeowners pulling a single-family permit, the realistic range is $35 to $400. For commercial or stamped work, expect $1,000 and up. Here's how those numbers break down.
The Five Price Tiers in 2026
Site plan costs cluster into five tiers based on who produces the drawing and what level of certification you need.
InQI AI site plan generator — $35 to $75 per address. InQI generates a scaled, editable site plan from any US address or Assessor's Parcel Number (APN) in under 60 seconds. Pricing is per address, with three tiers — Foundation ($35), Foundation Pro ($55), and Foundation InSight ($75) — that unlock progressively more data: aerial imagery, the editor, codes and zoning context, smart binders, and the InQuest context-aware AI. No drafter, no waiting.
Online drafting services — $89 to $259. Companies like GetASitePlan draft from county parcel data and deliver a PDF in 24 hours. Add-ons stack: vicinity maps run about $20, topographic contour lines add $40, rush under 12 hours can double the base. These plans are non-certified.
Local drafter — $150 to $400. A drafter in your area can include details an online service may miss, like septic locations or a neighbor's fence line. Turnaround is 2–5 business days.
Architect-drawn plans — $2,000 to $20,000. Architects price by project scope, not by drawing. A site plan inside a larger design package is rarely billed separately. Hourly rates run $100–$250.
Licensed surveyor — $475 to $3,200; up to $25,000 for complex commercial parcels. A surveyor's plan is a legal document with stamps and seals — you pay for liability and a field visit, not just the drawing. Most counties only require this for boundary disputes, mortgage lending, subdivisions, or specific permit categories.
What Actually Changes the Price
Five factors move the number more than anything else:
Whether your county requires a stamp. Stamped surveys cost 5–10x more than drafted plans. Most counties don't require a stamp for standard residential permits, but some do — call the permit counter first.
Lot size and complexity. A flat half-acre rectangle costs less than a sloped, irregular three-acre parcel. Topographic contours alone can add $40–$200.
Turnaround time. Rush jobs cost 50–100% more. A 6-hour rush at an online drafter often matches a 3-day standard order at a local one.
Required detail. Driveways, fences, accessory structures, well/septic, parking, and landscape each push you up a package tier.
Whether you need ongoing access. A drafter delivers a static PDF. An InQI project lets you keep editing the plan, layer in code checks, and revisit aerial imagery — useful when a county asks for a revision two weeks later.
How InQI Compares on Cost and Time
InQI generates a scaled, editable site plan from any US address or APN in under 60 seconds, drawing from the same county parcel and topographic data your building department uses. Direct comparison on a typical residential project:
Method | Typical cost | Turnaround |
$35–$75 per address | Under 60 seconds | |
Online drafter | $89–$259 | 24 hours (rush extra) |
Local drafter | $150–$400 | 2–5 business days |
Licensed surveyor | $475–$3,200 | 1–3 weeks |
InQI's three tiers are designed for different needs: Foundation ($35) is the entry point — site plan, aerial imagery, and the editor. Foundation Pro ($55) adds InQuest, the context-aware AI that pulls in your project's data when you ask it questions. Foundation InSight ($75) is the most complete tier — every data point from Foundation and Pro plus the InQuest AI Consensus Engine.
If your project still needs a code or zoning check before you submit, Codes.IQ looks up the rules for your specific address — setbacks, buildable area, height limits — so you can confirm compliance against the same plan you just generated.
Frequently Asked Questions
How much does a site plan cost for a building permit?
For a standard residential permit, $35–$400 is the common range. InQI starts at $35 per address and generates the plan in under 60 seconds; an online drafter or local drafter typically falls between $89 and $400 with a 1–5 day turnaround. Whether your county will accept a non-stamped plan varies by jurisdiction — call your building department's permit counter and ask.
Why are surveyor site plans so much more expensive?
A licensed surveyor performs a field measurement, carries professional liability, and stamps the drawing as a legal record. You're paying for the certification, not just the drafting work. Most residential permits don't require this — but boundary disputes, subdivisions, and certain commercial projects do.
Is an InQI site plan accepted by counties?
InQI generates plans from official county parcel and aerial data. Acceptance depends on your county's specific submittal requirements. Most jurisdictions accept a clearly scaled and labeled site plan that shows property lines, setbacks, structures, and the proposed work. Confirm with your local building department before submitting.
What's the cheapest way to get a usable site plan?
For a single project, InQI's Foundation tier at $35 per address is the cheapest usable option — generated in under 60 seconds and editable in the browser. Online drafting services start around $89 if you'd rather have someone deliver a PDF for you. Most online services include minor revisions; surveyors and architects typically bill revisions outside the original scope.
What's the difference between Foundation, Foundation Pro, and Foundation InSight?
Foundation ($35) includes the AI site plan, aerial imagery, and the editor — the entry point for a single project. Foundation Pro ($55) adds InQuest, InQI's context-aware AI assistant trained on your project's data. Foundation InSight ($75) includes everything in Foundation and Pro plus the InQuest AI Consensus Engine, which compares signals across multiple data sources to surface the highest-confidence answer for code, zoning, and feasibility
questions.
Get Your Site Plan in Under 60 Seconds
Skip the drafter wait. Sign up for free and run your address or APN through InQI — you'll have a scaled, editable site plan ready to mark up before a drafter would have replied to your email. Plans start at $35 per address.
Once it's drawn, check your zoning and setbacks in Codes.IQ so the plan is right the first time you submit.
