How Much Does a Site Plan Cost? (2026 Price Guide)

A site plan costs anywhere from $29 to several thousand dollars, and the spread comes down to one question: does your permit office need a drawing, or does it need a licensed surveyor's stamp? For a fence, deck, shed, pool, or patio permit, the answer is almost always a drawing. A non-certified, permit-ready site plan runs $89 to $259 from online drafting services, $150 to $400 from a local drafter, and $29 from Ergeon's GIS-based site plan, delivered in about 15 minutes. When the checklist says "certified" or "stamped," a surveyor-prepared plan is required, and that typically runs $1,000 or more with a one to three week wait. An architect's site plan for an addition or new build is in a different category again, often $1,000 to $5,000 as part of a larger set. Here is what each tier costs, what moves the price inside each tier, how to tell which one you need, and how to avoid paying for a survey you do not need.

Site plan cost by who prepares it

This table presents a comparison of different sources for obtaining site plans, including their typical cost, turnaround time, and certification status. It lists options such as Ergeon GIS-based site plans, online drafting services, local drafters, DIY GIS printouts, licensed surveyors, and architects or engineers. Each option is detailed with price ranges from free or low-cost to several thousand dollars, turnaround times ranging from minutes to weeks, and an indication of whether the resulting plans are certified. This information is useful for decision-making regarding site plan procurement based on budget, timing, and certification needs.

The first four rows produce the same category of document: a scaled drawing from county records showing your lot, structures, setbacks, and proposed work. The price difference is speed, how much of the work you do yourself, and how much hand-holding comes with it. The last two rows are different products. A surveyor's plan carries a legal determination of the boundary. An architect's plan is one sheet in a construction set.

What drives the price of a site plan?

Within any tier, a few things move the number:

Certification. The single biggest factor. A surveyor's stamp means fieldwork, deed research, and professional liability, which is why certified plans start around $500 at the very low end and commonly run $1,000 or more. If your permit office does not require it, you are paying for something the reviewer will not use.
Parcel complexity. Large, irregular, or wooded lots cost more from a surveyor and sometimes from a drafter. GIS-based plans like Ergeon's are a flat $29 for standard residential lots.
Project type. An ADU or addition plan needs more detail (lot coverage, parking, elevations) than a fence plan, and drafting services often charge a higher tier for it.
Source documents. If you have a prior survey or plat to trace from, a drafter's work is faster and cheaper. If the drafter has to reconstruct the lot from scratch, the price rises.
Revisions. Permit offices send plans back for missing elements. Some services charge per revision; Ergeon includes one free revision, and several online services include corrections when the city comments.
Turnaround. Rush fees are common for surveyors and local drafters, often 25 to 50 percent. A 15-minute GIS plan has nothing to rush.

What does the $29 Ergeon site plan include?

Ergeon's site plan is built from county parcel records and verified building footprints. For $29 you get a permit-ready PDF, printed at 11 by 17, showing:

Property lines and lot dimensions
The building footprint and other structures
Measured setback distances
Adjacent parcels and street context
Scale and a north arrow

It arrives by email in about 15 minutes, no account required, and one free revision is included if your permit office sends it back. The Project Planner tier adds a proposed fence layout you can print, mark up, and turn into a free Ergeon quote, usually by the next business day. A Hero Render add-on produces a photorealistic image of the property for HOA submissions or listings. It is the same GIS site plan Ergeon uses as the base for its own permit filings, with your fence layout and any other documents the city requires added on top.

One caveat applies to this and every records-based plan: parcel data is a starting canvas, not a legal boundary determination. Only a licensed surveyor can establish your property line. Ergeon's guide to site plan vs. survey vs. plot plan explains where that line sits.

This infographic details the cost differences for obtaining a site plan through three different options: Ergeon, a Drafter, and a Surveyor. Ergeon offers a GIS-based, permit-ready site plan for $29, typically completed in about 15 minutes. Using a Drafter costs between $89 and $400, depending on whether it is an online service or local drafter, with a turnaround time of 1 to 10 days. A certified Surveyor's plan starts at $1,000 and is required only when a checklist specifies the need for a certified plan. The data is sourced from Ergeon’s permit guide and reflects pricing from 2026 cost guides and provider rates. This comparison aids professionals and property owners in selecting the appropriate service level for their site plan needs.

Which tier do you actually need?

Work backward from the permit checklist:

Download the application for your exact project type. The fence permit application, not the general building page. Read the site plan or plot plan section.
Look for the words "certified," "stamped," "sealed," or "licensed surveyor." If they are there, budget $1,000 or more and one to three weeks. If they are not, a drafted plan is what the office expects.
Check whether the boundary itself is in question. A disputed line, missing corner pins on a fence built to the inch, or a lot that has changed since the last survey all point to a surveyor regardless of what the permit requires. Ergeon's guide to property line survey cost covers that decision.
If neither applies, order the cheapest plan that meets the checklist. For a fence permit that is usually the $29 GIS plan, and Ergeon's guide to whether you need a site plan for a fence permit lists what it must show.

The most expensive mistake homeowners make here is calling a surveyor first because that is the only professional they can think of, receiving a $1,500 quote with a three-week lead time, and assuming that is what a site plan costs. For a 6 ft backyard fence, it almost never is.

How does site plan cost compare with the rest of a fence project?

Context helps. Based on Ergeon's last 12 months of projects, most homeowners pay about $22 to $56 per linear foot installed for wood and $36 to $68 for vinyl, so a 150 ft privacy fence runs from the low thousands to around $10,000. Permit fees vary by city, often $50 to a few hundred dollars. Against those numbers, a $29 site plan is a rounding error, a $250 drafted plan is small, and a $1,500 survey is a line item worth questioning unless the boundary genuinely needs it. National averages in Ergeon's wood fence costs and vinyl fence costs guides run roughly $44 to $67 and $44 to $70 per foot.

Can you make a site plan for free?

Sometimes. Many cities accept a hand-drawn, to-scale plan on a printout from the county GIS map for simple residential lots, and if you have a survey or plat from your closing packet, you can trace from it. The trade-offs are time, the risk of a resubmittal for a missing element, and the fact that any property-line error is yours. If the GIS printout is grainy or the lot is irregular, the $29 plan removes most of that risk for less than the cost of a second trip to the permit counter. Ergeon's guide on how to get a copy of your property survey covers where to find existing drawings for free.

How does the site plan fit into an Ergeon fence project?

If your fence needs a permit, Ergeon's project manager handles the filing after you approve the quote, using the same GIS site plan as the base with your fence layout added. The quote happens without a sales visit: draw the line on a satellite map for an instant estimate, confirm slope, gates, access, and removal with a specialist on a live video call, and approve an itemized quote online. Ergeon is licensed, bonded, and insured in every market it serves, holds a 4.81 out of 5 rating across more than 22,000 verified reviews, and typically schedules builds within about 20 days of approval.

FAQ

How much does a site plan cost?
From $29 for Ergeon's GIS-based permit-ready plan, $89 to $259 from online drafting services, and $150 to $400 from a local drafter. A surveyor-certified site plan typically costs $1,000 or more, and an architect's site plan for an addition or new build often runs $1,000 to $5,000 or more.

Why is a surveyor's site plan so much more expensive?
Because it includes a legal boundary determination: deed research, field measurement, monument setting, and a stamp that carries professional liability. A permit office only needs that when the checklist says certified or the boundary is in question.

Does a site plan for a fence permit need a stamp?
Usually not. Most cities accept a scaled drawing from county records for fence, deck, shed, and pool permits. Read the application for the words certified, stamped, or sealed; if they are absent, a drafted plan is what the office expects.

How long does it take to get a site plan?
About 15 minutes for Ergeon's GIS-based plan, one to two days from online drafting services, three to ten days from a local drafter, and one to three weeks from a surveyor.

Is the $29 Ergeon site plan accepted by permit offices?
It includes the elements permit offices ask for: property lines, building footprint, setbacks, scale, and north arrow, drawn from county parcel records and verified building footprints. If your office rejects it, one revision is free, and if it cannot be made right, Ergeon refunds the order.
