Site Plans: The Master Plan for Your Home

Every spring, when my wife and I sit down to plan out what we want to grow for the upcoming season, we take the time to draw out how we want to the garden to be organized. We start with a blank sheet of graph paper, sketch out each section of the garden, and plug and play each veggie and flower where they make the most sense.

When you build a home, this kind of planning is just as important. There's lots of different subcontactors, utility companies, and planning committees that want to know how your building site is going to be laid out. This is equally important for us as the builder, because it helps coordinate all of this information and keep everyone on the same page.

An example site plan. Note all of the different items marked out for reference.

What is a Site Plan?

A site plan is a complete set of technical drawings and documents that describe, in detail, how a building will be constructed on a specific piece of land.

Site plans are different from architectural floor plans, though the two are often confused. A floor plan shows the interior layout of your home, whereas a site plan zooms out to 30,000 feet and answers a different set of questions: Where exactly does the home sit on the lot? How does the land drain? Where do the utilities come in? How does the driveway connect to the road?

Floor plans design the house, site plans design the relationship between the house and the land it sits on.

Before Unshakeable Custom Homes can pull a building permit, a complete set of site plans must be reviewed and approved by the Lincoln County Planning and Zoning Committee. In Star Valley, Wyoming, that means compliance with Lincoln County zoning ordinances, setback requirements, and (depending on your lot) state-level environmental regulations.

Why Site Plans Matter More Than You Think

It's tempting to see a site plan as useless red tape. In reality, the planning phase is where the most important (and often budget driven) decisions are made. This is important because most of us are not building a home by writing a blank check! So why does a site plan matter?

They prevent expensive surprises.

Discovering a problem on paper only costs time to fix. Discovering it after a foundation is poured can cost tens of thousands of dollars. Site plans allow trades to coordinate with us before anyone picks up a tool. Conflicts get resolved in the design phase, not in real time on the job site.

They protect your investment.

A properly permitted build has a clear chain of approvals that any future buyer, bank, or insurance company can verify. A home built without proper documentation can face serious issues at resale, refinancing, or in the event of an insurance claim.

They are a quality control tool.

As a homeowner, your construction documents give you a benchmark. When complete a weekly job site review with us, you can compare what's been built to what was planned. The plans are a shared language between you and us.

They communicate your vision precisely.

Words and sketches are ambiguous, engineered drawings are not! A detail in the plans saying "window header at 9'6" above finished floor" means the same thing to a framer in Star Valley, Wyoming as it does to an inspector in Afton. We work best with that level of precision.

Building a Custom Home in Star Valley, Wyoming: What Makes Our Site Plans Different

Star Valley, Wyoming sits at an average elevation of 5,600 to 6,200 feet, with terrain that ranges from flat valley floor to steep hillside lots. That means no two site plans will look alike. Here's examples of things you may not have seen on a site plan if you've never built in a rural area:

Snow Load & Seismic Requirements

Star Valley, Wyoming's building codes require structural plans to account for significant roof snow loads. In Star Valley, ground snow loads can exceed 100 pounds per square foot. The structural engineer must calculate and specify roof framing to meet or exceed these values.

We also live in an active seismic zone, which creates it's own set of engineering requirements. These relate to shear transfer through a building from seismic activity, as well as high wind speeds.

Ultimately, the structural engineer must have a Wyoming stamp to legally release plans to be built in Wyoming, and they must be built to withstand seismic activity, high winds, and large snow loads.

The old timers used to say that if the wind stopped blowing in Eastern Wyoming, everyone would fall over!

Septic and Well Systems

Most Star Valley, Wyoming lots are not connected to municipal water and sewer. That means your site plan will include a septic system design (designed by a qualified civil engineer and reviewed and approved by the Wyoming DEQ) and a well permit from the Wyoming State Engineer's Office.

The location of both is carefully coordinated on the site plan to meet separation distance requirements from ground water and well systems. This coordination happens at the beginning of the planning stage.

Drainage and Grading

Spring snowmelt (really just water and snowmelt in general!) in Star Valley, Wyoming can move a significant amount of water across a property. Understanding how water will move across your lot, as well as having a qualified excavator on your team that understands how to manage that water, is one of the most important elements of the site plan.

Setbacks and Easements

Lincoln County, Wyoming zoning code establishes minimum setbacks from property lines, road right-of-ways, and waterways. Most parcels also carry easements that affect where your home can be placed. Your site plan will reflect all of these, and we will review them with you before you fall in love with a particular home placement on the lot.

How the Site Planning Process Works with Unshakeable Custom Homes

If you've never built a custom build, here's a simplified look at how creating a site plan fits into the overall timeline:

Step 1: Land Assessment

Before any drawings begin, we will walk your land with you. This is about understanding drainage patterns, prevailing winds, solar orientation, access points, and any constraints that will shape the design of your home. This is that stage that the site plan starts to take shape.

Step 2: Preliminary Design

You work with an architect or designer to establish the home's size, layout, and general form. This phase produces rough floor plans and a basic site plan that we will continue to refine during pre-construction.

Step 3: Design Development

The home design gets refined and engineered, and critical mechanical (think electrical, plumbing and HVAC) systems are designed using energy modeling. We work closely with the subcontracted trades to value engineer and produce any shop drawings needed. This is the phase where trade coordination happens and design conflicts are resolved.

Step 4: Construction Documents

The full drawing set is completed, coordinated, and signed off by the relevant licensed professionals. This is what gets submitted to Lincoln County Planning and Zoning for permit. This drawing set includes the site plan, floor plan, structural drawings, and any mechanical plans (plumbing, HVAC and electrical).

Step 5: Permit Review & Approval

Lincoln County's Planning and Zoning department reviews the submitted plans for code compliance. They may request revisions or clarifications. Once approved, you receive a building permit!

Step 6: Construction Administration

Once construction begins, the plans remain as a living document. Inspectors reference them at key milestones, and we will reference these plans daily as we work through the physical building of your home. Any change to these plans that affect structure, energy compliance, or life safety must be formally documented.

The Bottom Line

A site plan is an important part of the pre-construction and design phase. It's crucial in bringing a design from two-dimensional drawing to your home. Although our site plans can be detailed, a high level of detail allows our carpenters and the subcontracted trades that come in after to have a baseline understanding of your vision.

At Unshakeable Custom Homes, we walk our clients through this process and handle all the red tape we may need to cut through. This white-glove approach allows you to make decisions, and us execute without having to worry if it's being done right.
