Site Plans That Pass Plan Review the First Time

Nearly every Colorado permit application — additions, ADUs, garages, decks, new construction, and change-of-use projects — requires a site plan showing where the work sits on the property. Many applications stall for weeks because the site plan is hand-drawn, missing setbacks, or doesn't show what the reviewer needs. We prepare professional, permit-ready site plans formatted to your specific jurisdiction's requirements: property lines and dimensions, setbacks with the proposed structure's compliance shown, existing and proposed structures, driveways and access, utilities and easements, and grading/drainage where required. When your project needs engineering support behind it — drainage compliance, structural coordination — it's in-house, not a subcontract.

What Your Site Plan Shows

A complete site plan from our firm includes: • Property lines, lot dimensions, and legal description basis • Setback lines with the proposed structure's distances shown • Existing and proposed structures with footprints and square footage • Driveways, walkways, and vehicle access • Utility locations and connections — water, sewer, power, gas • Easements and right-of-ways • North arrow, scale, and datum information • Finished floor elevation and grade relationship • Grading and drainage direction where required • Flood zone notation where applicable We match the format your building department expects — some want a full civil sheet, others a simple plot plan. We prepare both, and we know which cities require which.

When You Can Skip the Surveyor — and When You Can't

For additions, ADUs, and accessory structures, many Colorado jurisdictions accept a scaled site plan prepared from the recorded plat and property dimensions — which is faster and far less expensive than a full boundary survey. We prepare these daily and know which jurisdictions accept them. When a survey is genuinely required — new construction, lot-line adjustments, complex parcels, or jurisdictions that demand a licensed surveyor's certification — we'll tell you plainly, and we coordinate with your surveyor's data so the site plan is built on accurate information. You'll never pay us to guess at a boundary that your city is going to reject.

Cost and Turnaround

Most residential site plans run $300–$900 depending on complexity and what the jurisdiction requires. Turnaround is typically 2–4 business days. Call (888) 305-3967, tell us your city and project type, and we'll quote it directly — including whether you actually need a surveyor first.

Site Plans & Engineering — Frequently Asked Questions

What is a site plan and why do I need one?

A site plan is a scaled drawing showing your property and where the proposed work sits on it — setbacks, structures, access, utilities, and drainage. Building departments require it to verify your project complies with zoning (setbacks, lot coverage, height) before issuing a permit. A professional site plan prevents the most common cause of residential permit delays.

Can I draw my own site plan?

Many jurisdictions accept homeowner-drawn plans, but they're the #1 source of resubmittals — missing setbacks, wrong scales, and unstated assumptions send applications back for weeks. A professionally prepared site plan costs a few hundred dollars and is frequently the difference between a first-pass approval and a month of delay.

Do I need a surveyor before getting a site plan?

Often no — for additions, ADUs, and accessory structures, many Colorado jurisdictions accept a scaled site plan based on the recorded plat. Some projects and jurisdictions do require a licensed survey. Call us with your city and project type; we'll tell you which applies and can coordinate with a surveyor if one is needed.

How much does a site plan cost in Colorado?

Most residential site plans run $300–$900 depending on the jurisdiction's requirements and project complexity. Complex parcels, multi-structure sites, and projects needing grading plans cost more. Call (888) 305-3967 for a firm quote.

How fast can you prepare a site plan?

Typically 2–4 business days. Rush service is available for time-sensitive permits. We deliver in the exact format your building department expects — digital PDF, printed sets, or portal upload.
