Anywhere from $29 to $25,000 — depending on who draws it, what your county requires, and how fast you need it. For most homeowners pulling a single-family residential permit, the realistic range is $29 to $400.
The Five Price Tiers in 2026
InQI AI site plan generator — from $29/month
The AI Site Plan Generator creates a scaled, editable site plan from any US address or Assessor's Parcel Number (APN) in under 60 seconds. Built from county parcel records and aerial imagery. Export to PDF, DXF, or SVG. Includes setback lines, lot dimensions, and existing structure detection.
Online drafting service — $89 to $259
You provide the address and project description; they deliver a PDF in 24 hours. Works well for straightforward residential lots. No editing or iteration.
Local drafter or permit expediter — $150 to $400
Local knowledge can help with specific county requirements. Typical 2–5 business day turnaround. Usually a PDF-only deliverable.
Architect-drawn site plan — $2,000 to $20,000+
Part of a full architectural package. Appropriate for complex projects, commercial work, or when you need construction documents alongside the site plan.
Licensed surveyor — $475 to $3,200 (residential); up to $25,000 for commercial parcels
Physically field-measured, stamped, and legally certified. Required for mortgage lending, boundary disputes, subdivision applications, and a small number of strict municipal permit applications.
What Actually Changes the Price
Whether your county requires a stamp. Stamped surveys cost 5–10x more than non-stamped site plans and take weeks, not hours.
Lot size and complexity. Irregular lots, significant slope, multiple structures, and recorded easements all increase time and cost.
Turnaround time. Rush orders cost 50–100% more from drafters and surveyors.
Required detail level. A basic deck permit site plan needs far less than a full ADU permit package.
