Buying Land to Build a House? What to Check Before You Buy

Sep 8

Buying land can be one of the most exciting steps in planning a new home.

You see the view, the trees, the privacy, or the open space and immediately begin imagining where the house might sit.

But before you buy, there is a much more important question:

Will this property actually support the home, budget, and lifestyle you are planning?

In this video, I walk through some of the most important things I believe homeowners should investigate before buying land to build a house.

What You'll Learn in This Video

Before buying a building lot, you need to look beyond acreage and appearance.

We'll talk about important questions involving:

```
Zoning and building restrictions
```
```
Setbacks and easements
```
```
The actual buildable area
```
```
Access and driveway placement
```
```
Slope and topography
```
```
Drainage and flood conditions
```
```
Soil and foundation considerations
```
```
Water and sewer availability
```
```
Wells and septic systems
```
```
Electric and other utilities
```
```
Site-development costs
```

How the property should influence the house plan

The goal isn't to find a property with no challenges.

The goal is to understand the challenges before you own them.

The Direct Answer

Before buying land to build a house, determine whether the property can legally, physically, and financially support the project you have in mind.

That means investigating more than the property lines.

You need to understand where you can actually build, how the house will be accessed, how utilities will reach it, where water will drain, what kind of foundation conditions may exist, and how much money may need to be spent preparing the land before construction of the house even begins.

Do not decide that a lot is affordable based only on its purchase price.

The real question is:

What will this property cost once it is ready for the house?

1. Find the Actual Buildable Area

A two-acre property does not necessarily give you two acres on which to place a house.

The usable building area may be reduced by:

```
Front setbacks
```
```
Side setbacks
```
```
Rear setbacks
```
```
Utility easements
```
```
Drainage easements
```
```
Access easements
```
```
Septic areas
```
```
Wells
```
```
Flood conditions
```
```
Steep slopes
```
```
Existing utilities
```
```
Deed restrictions
```
```
Environmental conditions
```

This is why property size alone can be misleading.

The first question isn't:

How big is the lot?

It is:

Where can we actually build?

2. Check Zoning, Restrictions, and Easements

Before assuming you can build the home you want, verify what local regulations and private restrictions will allow.

Depending on the property, questions may include:

```
Is residential construction permitted?
```
```
What setbacks apply?
```

Is there a minimum or maximum home size?

```
Are there building-height restrictions?
```
```
Are accessory buildings allowed?
```

Can you build a detached garage or workshop?

Are there restrictions on RV or boat storage?

Are particular exterior materials required?

Are there recorded easements crossing the property?

Are there subdivision or deed restrictions?

Do not assume that because neighboring properties have houses, your plans will automatically be allowed.

Investigate the specific parcel.

3. Understand the Slope

Slope can completely change a project.

Sometimes it creates an opportunity.

A sloping property may make a walkout basement practical, improve views, or allow a home to step naturally into the land.

But slope can also affect:

```
Excavation
```
```
Foundation height
```
```
Retaining walls
```
```
Driveway grade
```
```
Drainage
```
```
Garage placement
```
```
Outdoor living areas
```
```
Construction access
```
```
Landscaping
```
```
Final grading
```

A house designed for a flat property may become expensive or awkward when forced onto a steep lot.

Instead of asking how to make your favorite plan fit the land, ask:

What type of house does this land naturally want to support?

4. Study Where the Water Goes

Water always needs somewhere to go.

Look at the property during or shortly after heavy rain if possible.

Ask where water enters the site, where it travels, and where it leaves.

Drainage conditions can affect:

```
House elevation
```
```
Foundation design
```
```
Driveway placement
```
```
Basement feasibility
```
```
Retaining walls
```
```
Landscaping
```
```
Finished grading
```
```
Stormwater management
```

A low area that looks harmless during dry weather can tell a very different story after several inches of rain.

Good site planning works with natural drainage rather than pretending it does not exist.

5. Investigate Soil and Foundation Conditions

The ground underneath the house matters just as much as the rooms above it.

Different soil conditions can affect excavation, drainage, foundation design, septic feasibility, and construction cost.

Depending on the location and project, you may need information from qualified local professionals regarding:

```
Soil bearing conditions
```
```
Expansive soils
```
```
Rock
```
```
Groundwater
```
```
Fill
```
```
Septic suitability
```
```
Foundation recommendations
```

You don't necessarily need to become an expert in soil.

You need to know when the soil requires an expert.

6. Verify Water and Sewer — Don't Assume

Seeing houses nearby does not mean your property has inexpensive access to public water or sewer.

Ask the utility provider directly.

Determine:

Is service available to this exact property?

```
Where is the connection?
```
```
How far is it from the proposed house?
```
```
Are extension costs involved?
```
```
Are there connection or impact fees?
```
```
Will a road need to be crossed?
```
```
Will pumping equipment be required?
```

A utility may be nearby and still be expensive to reach.

Get property-specific information rather than relying on assumptions.

7. Understand Well and Septic Requirements

If public water or sewer isn't available, the property may require a well, septic system, or both.

That introduces another layer of site planning.

The septic system needs somewhere to go.

The well needs somewhere to go.

The house needs somewhere to go.

The driveway needs somewhere to go.

Future garages, workshops, pools, patios, or other improvements may also need room.

Those uses can compete for the same portion of the property.

That is why septic planning shouldn't happen after the house has already been placed on the site.

8. Think About the Driveway Before the Floor Plan

The driveway connects the road to one of the most important parts of the house—the garage.

Study:

```
Road access
```
```
Sight distance
```
```
Culvert requirements
```
```
Driveway slope
```
```
Length
```
```
Curves
```
```
Drainage
```

Snow or weather conditions where applicable

```
Construction access
```
```
Delivery-truck access
```
```
Garage orientation
```

A garage that looks perfect on the floor plan may create an awkward driveway once the plan reaches the actual property.

The house, garage, driveway, and road should work together.

9. Verify Your Utilities

Electricity, gas, internet, and other services deserve attention before you buy.

Ask where each service is located and what it may cost to reach the proposed house location.

A long distance from the road to the house might provide wonderful privacy.

It may also mean longer runs for:

```
Electricity
```
```
Water
```
```
Gas or propane
```
```
Internet
```
```
Driveway
```
```
Drainage
```
```
Temporary construction utilities
```

Those costs can consume money you expected to spend on the house itself.

10. Estimate the Cost of Making the Property Buildable

The purchase price of the land is only the beginning.

Depending on the site, preparing it for construction could involve:

```
Surveying
```
```
Clearing
```
```
Tree removal
```
```
Excavation
```
```
Fill
```
```
Rock removal
```
```
Retaining walls
```
```
Drainage
```
```
Utility extensions
```
```
Well
```
```
Septic system
```
```
Driveway
```
```
Culverts
```
```
Foundation upgrades
```
```
Landscaping
```
```
Engineering
```

This is why I believe the land budget and house budget have to be considered together.

Spending more on an easier property can sometimes produce a less expensive overall project than buying cheaper land that requires extensive development.

Let the Lot Help Design the House

One of the most important principles in residential design is simple:

The property should help shape the home.

Study:

```
Where the best views are
```
```
Where the sun rises and sets
```
```
Where neighboring homes sit
```
```
Where privacy matters
```
```
How the driveway approaches
```
```
How the property slopes
```
```
Which direction water drains
```
```
Where utilities enter
```
```
Where outdoor living makes sense
```

Then begin developing the house around those conditions.

A home that belongs on its property will usually work better than one that was designed somewhere else and forced onto the site later.

A Common Mistake

One of the biggest mistakes is buying the property emotionally and investigating it technically afterward.

I understand why this happens.

You walk the land.

You see a beautiful view.

You imagine the porch.

You picture children or grandchildren playing outside.

Before long, you've mentally built the house.

That excitement is part of what makes building a home special.

But give yourself permission to enjoy the property and still investigate it objectively.

Falling in love with a lot should not stop you from asking what it will take to build there.

What I've Learned From Residential Design

Over nearly five decades of residential design and building-material experience, I've seen how dramatically the building site can influence a project.

Two houses with similar square footage can have very different construction costs simply because they sit on different properties.

One site may allow straightforward excavation, a simple foundation, short utility runs, and an easy driveway.

Another may require extensive grading, retaining walls, long utility extensions, difficult access, special foundation work, or a complicated septic system.

That doesn't automatically make the second property a bad choice.

It means those conditions should be part of the decision before the purchase price convinces you the property is affordable.

Questions I Would Ask Before You Buy the Lot

If we were reviewing a property together, I would want answers to questions like these:

Where are the actual property boundaries?

```
What setbacks apply?
```
```
Are there recorded easements?
```
```
Are there private restrictions?
```
```
Where is the practical buildable area?
```
```
How does the property slope?
```
```
Where does stormwater travel?
```

Is any portion of the property in a flood-prone area?

```
What do we know about the soil?
```
```
Is public water available?
```
```
Is public sewer available?
```

If not, can the property support a well and septic system?

```
Where is electrical service?
```
```
How will the driveway reach the house?
```

Is there room for the garage orientation you want?

Can construction vehicles reach the building site?

What site-development costs should be added to the budget?

Does the lot actually support the house and lifestyle you are planning?

You may not have every answer immediately.

But those are exactly the kinds of questions worth asking before closing on the property.

Your Next Steps

Before purchasing land to build:

Obtain and review reliable property information.

Verify zoning and setbacks with the appropriate local authority.

Review easements and private restrictions.

```
Identify the actual buildable area.
```

Investigate slope, drainage, flood, and soil conditions.

Verify utilities directly with the providers.

Investigate well and septic requirements when applicable.

Think through driveway and construction access.

Develop a preliminary site plan before becoming committed to a house plan.

Estimate site-development costs and include them in your total project budget.

Then decide whether the property is right for the project—not simply whether you like the property.

Confirm zoning, setbacks, easements, and restrictions before buying.

Study slope, drainage, soils, utilities, and access.

Understand well and septic requirements when public services aren't available.

Include site-development expenses in the total project budget.

Don't force a favorite floor plan onto the wrong property.

```
Let the land help shape the house.
```

Understand the property before becoming financially and emotionally committed to it.
