Plans typically start at $1,800, delivery runs 3–6 weeks, and every set ships with the engineer’s stamp Utah permit offices require. Call (435) 623-0897 or request a quote online.
Most Utah drafting services produce pretty floor plans but can’t stamp them. We do both — drafting AND engineering under one roof — so your house plans go from sketch to building-permit-ready without ever leaving our office. That’s the practical difference between a drafter and an engineering firm with a drafter on staff.
Our Drafting Services
“House plan drafting” can mean a lot of different things — a quick floor plan sketch, a full custom home design, an addition drawing for a building permit, or stamped engineered blueprints for a builder. Ludlow Engineering’s drafting services cover the full range. Here’s what we do most often for Utah clients:

Looking for custom house plans in Utah? Most homebuyers we work with end up here for one of two reasons: either they bought stock house plans online and discovered they don’t account for Utah’s snow loads, seismic zones, or local building codes — or they fell in love with a lot and need a custom design that actually fits it. Either way, we draft from scratch.
Custom house plans drafted by Ludlow Engineering include everything a Utah builder needs to break ground:
- Site plan showing the home’s location on your lot
- Floor plans for each level with dimensions and room labels
- Exterior elevations for all four sides of the house
- Building sections showing how the home is constructed vertically
- Foundation plan engineered for your soil and snow loads
- Roof framing plan
- Electrical, plumbing, and HVAC schematic layouts
- Door, window, and finish schedules
- Construction details for non-standard conditions
- Engineer’s stamp on the structural elements
Common Utah-specific design considerations we handle as standard:
- Wasatch Front snow loads — ranging from 30 psf in the valley to 100+ psf above 6,500 feet
- Seismic design category — D2 or higher for most of Utah, requiring engineered shear walls and hold-downs
- High-altitude building envelope — different insulation and vapor-barrier requirements above 6,000 ft.
- Wildland-urban interface fire codes — for benchland, foothill, and Park City area homes
- Local jurisdiction quirks — Salt Lake City, Park City, Provo, and St. George each have their own plan-check expectations
Utah House Plans for Every Style
Utah’s housing styles range from traditional craftsman homes on the Wasatch Front to modern mountain contemporaries in Park City, southern Utah desert designs, and rural acreage homes in central Utah counties. We’ve drafted Utah house plans across all of them — and our team will draft the architectural style you want, not the style we have on file.
Residential Drafting Services for Utah Homeowners
Our residential drafting services cover everything a homeowner needs drafted between “I have an idea” and “the builder broke ground” — whether that’s a brand-new home, an addition, a basement finish, a remodel, or a shop building.
Most residential drafting projects we take on in Utah fall into one of these buckets:
New Construction Home Plans
A full set of architectural and engineered drawings ready for building department submission. This is the most common residential drafting project — a Utah homeowner has bought a lot, has a builder in mind, and needs drawings to apply for their permit. Delivery typically runs 4–6 weeks for a custom home, less for modifications to an existing plan.
Additions & Remodels
Drafting for additions, second-story expansions, basement finishes, garage conversions, and significant remodels. These often require both architectural drafting (the new space) and as-built drawings of the existing structure, so the new work ties cleanly into what’s there.
Accessory Dwelling Units (ADUs)
ADUs are increasingly common in Salt Lake City, Provo, and other Utah jurisdictions that have eased zoning. We draft both attached and detached ADUs to whatever the local jurisdiction’s specific requirements are.
Shop Buildings & Accessory Structures
Detached shops, garages, barns, and other accessory buildings. Rural Utah homeowners often need these stamped for permit purposes — we draft and engineer in one package.
Architectural Drafting Services
Our architectural drafting services produce the technical drawing set that a building department requires for permit issuance. The terminology overlaps with “house plan drafting” — but architectural drafting specifically refers to the discipline of producing detailed building drawings: floor plans, elevations, sections, details, and schedules.
What’s in an Architectural Drafting Package
A typical Ludlow Engineering architectural drafting package for a Utah residential project includes:
- Cover sheet with project information, code summary, and sheet index
- Site plan showing the building’s location on the lot with setbacks and easements
- Floor plans for every level — fully dimensioned with room labels, window/door tags, and wall types
- Building elevations — north, south, east, west — showing exterior materials and finish heights
- Building sections showing wall, floor, and roof construction
- Wall sections for typical wall conditions
- Roof plan
- Construction details for non-standard intersections, eaves, foundations, etc.
- Door and window schedules
- Finish schedules if requested
For structural components — foundation engineering, framing engineering, lateral load calculations — our in-house engineers add stamped engineered sheets to the architectural set. See the engineered blueprints section below.
Floor Plan Drafting Services
Floor plan drafting is the discipline of producing accurate, scaled, two-dimensional drawings showing the interior layout of each floor of a building. It’s the foundation of every architectural drawing set — and sometimes it’s the only deliverable a client needs.
Common situations where Utah clients need standalone floor plan drafting services:
- An architect has done the conceptual design and just needs construction-ready floor plans
- An interior designer needs accurate as-built floor plans to design from
- A homeowner wants to evaluate remodel options before committing to full drafting
- A real estate professional needs marketing-quality floor plans for a listing
- A homeowner wants 2D floor plan drafting services for a permit they’re submitting themselves
Floor Plan Design Services
If you’re earlier in the process and want a designer to help you think through the floor plan itself — not just draft what you’ve already sketched — that falls under our floor plan design services. We meet with you, understand how you live, and propose layouts that fit your lot and budget. Then we draft the chosen design.
Engineered Blueprints & House Plan Engineering
An engineered blueprint is an architectural drawing set that includes structural engineering — sealed by a licensed Professional Engineer. Utah building departments require engineered drawings for most new construction, additions, and significant remodels. Without an engineer’s stamp, your permit application gets returned.
This is the single biggest practical advantage of working with Ludlow Engineering instead of a standalone draftsman: our drafters and engineers are in the same building. There’s no handoff, no coordination delay, and no risk of the engineer needing changes the drafter doesn’t want to make. The plans come out the door stamped, complete, and ready to submit.
What Engineered Blueprints Include
Beyond standard architectural drawings, engineered blueprints add:
- Foundation engineering — sized to your soil conditions, frost depth, and local geology
- Structural framing plans — joist, beam, and rafter sizes engineered to span and load
- Lateral load calculations — shear walls, hold-downs, and connections engineered to Utah seismic standards
- Snow load calculations — roofs designed to your site’s specific snow load
- Engineer’s stamp and signature on every structural sheet
- Code compliance statements referencing the applicable IBC or IRC edition
House Plan Engineer vs. House Plan Drafter
A house plan drafter produces the drawings; a house plan engineer certifies that the building those drawings describe will actually stand up. Most building departments require both. At Ludlow Engineering we provide both functions in-house — so you get one contract, one timeline, and one team accountable for the deliverable.
Home Plan Drafting
“Home plan drafting” and “house plan drafting” are essentially the same thing — both describe the process of producing detailed drawings for a residential building. We use them interchangeably. The deliverable is the same: a complete set of architectural drawings ready for your Utah builder and your local building department.

Who Draws House Plans for You?
A common question from first-time clients: “Who is actually drawing my house plans?” The answer at Ludlow Engineering: a professional drafter — typically with a background in architectural technology or construction — working under the direction of our licensed engineers. Your floor plan is drawn by someone who does it every day, then reviewed by an engineer who’ll personally stamp it. You’re not handed off to a junior contractor halfway through.

Our House Plan Drafting Process
Every drafting project follows the same five-phase process. We’ll explain it on the first call.
Sketch & Programming
We meet with you to understand the goal — how you live, how big the home is, what the lot allows, and what the budget supports. We rough out a sketch.
Site Evaluation
We evaluate your Utah lot — topography, soils, setbacks, snow load zone, seismic category. If you don’t have a topographic survey, we can produce one in-house. See our topographic survey services.
Schematic Design
You review preliminary floor plans and elevations. We iterate until the design is right. Most projects have 2–3 review rounds here.
Construction Documents & Engineering
The drafter produces the full construction drawing set. The engineer adds structural sheets and stamps the package. You get a final review before delivery.
Permit Support & Construction Observation
We respond to plan-check comments from your building department and provide construction observation services as the project gets built. You’re not abandoned at the permit counter.

Frequently Asked Questions
How much do house plan drafting services cost in Utah?
House plan drafting in Utah typically starts at $1,800 for a custom home plan under 2,500 sq ft. Larger custom homes (2,500–5,000 sq ft) run $3,500–$7,500. Stock plan modifications run $800–$2,000. Basement finishes and small additions start at $800. See our pricing table above for the full breakdown.
Who actually draws the house plans?
At Ludlow Engineering your plans are drafted by a professional drafter — typically someone with a background in architectural technology — working under the direction of our licensed engineers. The same drafter stays on your project from start to finish. Structural sheets are reviewed and stamped by a Utah-licensed Professional Engineer before delivery.
What’s the difference between a house plan drafter and a house plan engineer?
A house plan drafter produces the architectural drawings — floor plans, elevations, details. A house plan engineer certifies that the building those drawings describe will stand up — foundation sizing, framing capacity, lateral loads, snow loads. Utah building departments typically require both. At Ludlow Engineering we provide both in-house, so your plan set comes out stamped and permit-ready.
Do you offer engineered blueprints with stamps?
Yes. Every Ludlow Engineering house plan that requires structural engineering is sealed by a Utah-licensed Professional Engineer before delivery. The seal is what Utah building departments accept on permit applications.
Can I just get floor plan drafting without the full architectural set?
Yes. Standalone floor plan drafting services run $600–$1,800. This is appropriate when you already have an architect or designer and just need clean, scaled, construction-ready floor plans, or when you’re early in the process and want to see the layout before committing to a full set.
How long does house plan drafting take?
A full custom home plan typically takes 6–10 weeks from contract to delivery. Modifications to existing plans run 2–4 weeks. Floor-plan-only deliverables run 1–3 weeks. Timeline depends on size, complexity, the number of review rounds, and how quickly you respond to drafts. We confirm timeline in writing as part of the quote.
Do you draft additions and basement finishes?
Yes. Additions are a large share of our residential drafting work — second-story additions, room additions, garage conversions, and major remodels. Basement finishes typically run $800–$2,200 depending on complexity. Both usually require as-built drawings of the existing structure plus new construction drawings.
Can revisions be made after the plans are completed?
Yes, with caveats. Before construction starts, most revisions are straightforward — though significant changes may require additional drafting fees and a new engineering review. After construction has started, revisions are still possible but more involved — they may require redrawing, new permits, and additional engineer review. Changes that contradict building codes or significantly alter structural integrity may not be permitted.
Do you draft custom house plans for builders?
Yes. We work with Utah homebuilders on production house plans, multi-lot drafting packages, and optional layout variations. Volume pricing is available — call (435) 623-0897 for builder rates.
What software do you use for drafting?
We use industry-standard computer-aided design (CAD) software — AutoCAD and Revit for most projects. Deliverables are available in DWG, DXF, and PDF formats. You receive both digital and printable file sets.
Do you handle building permit submission?
We provide permit-ready drawings and respond to plan-check comments from your Utah building department, but the actual permit submission is typically handled by the property owner or builder. We can guide you through the process and answer questions from the plan-checker on your behalf.
Do you serve homeowners outside central Utah?
Yes. From our Nephi office we serve the entire state — Wasatch Front, central Utah, southern Utah, and northern Utah. Drafting is largely an office-based discipline, so distance is only a consideration when site visits or as-built measurements are required.
