New Construction Landscaping: What's Included, What You'll Pay Extra For - Realtor Cas Cassandra Marks

Published October 15, 2026. QUICK ANSWER: Most builders include only basic landscaping with a new construction home: grading, front yard seed or sod, and minimal foundation plantings. Backyard grass, trees, fencing, irrigation, and patios are usually a buyer expense, and every builder is different, so get the specifics in writing before you sign. In western Washington there is an added protection: WSU Extension reports that builders are required to stockpile and replace existing topsoil, or amend the soil with compost, so landscaped areas meet a post-construction soil standard of about 8 inches of soil with at least 5% organic matter for lawn and 10% for planting beds (Washington Department of Ecology BMP T5.13). Clark County publishes its own implementation procedure for builders. Ask your builder how the lot's soil depth was verified, avoid compacting it with heavy equipment, and do not alter grading or drainage features. This guide covers what's typically included, what costs extra, how to ask the right questions, and how to protect your yard's soil and drainage.

New Construction Landscaping: What's Included, What You'll Pay Extra For

The budget line most buyers skip, and the one that shows up the week after closing.

⚡ Quick Answer

What landscaping comes with a new construction home? Usually the basics: grading, front yard seed or sod, and minimal foundation plantings. Backyard grass, trees, fencing, irrigation, and patios are typically a buyer expense, and every builder is different, so never assume. In western Washington there's one added protection: builders are required to restore the soil in landscaped areas to a post-construction standard of about 8 inches of quality soil, which is why "the yard is just dirt" isn't the whole story. Ask what's included in writing, and ask how the soil depth was verified.

It's the week after closing. The house is perfect, the boxes are stacked, and then you look out the back window at a rectangle of bare dirt and realize nobody told you the yard was your job. It's one of the most common new-build surprises I see, and it's almost always avoidable with a few questions asked before signing.

This covers what builders typically include, what usually costs extra, one local rule about soil that works in your favor, and what to get in writing. If you haven't toured yet, what to ask on your first builder model home tour includes landscaping in the list of things to ask beyond the base price.

What Landscaping Is Usually Included With a New Construction Home?

The basics, and not much more

New Construction Landscaping

Across the builders and landscapers I looked at, the standard package is consistent: grading, front yard grass (seed or sod, depending on the builder), and a few foundation plantings. Anything beyond that, including full backyard grass, extra planting beds, trees, fencing, irrigation, and patios, is usually a separate buyer expense.

Some builders include more, and a few include less. That's the point: it varies, and it's easy to assume your builder is the generous one. Treat landscaping the way you'd treat any other line item, which means it should be spelled out in the builder's purchase agreement, not described in a brochure or promised at the sales desk.

Is the Soil in a New Build Yard Really Just Dirt?

In western Washington, there's a standard it has to meet

Construction strips and compacts a lot of ground, and in the past builders sometimes left yards with very little topsoil, planted on compacted layers of subsoil. That's changed here. According to WSU Extension's guide to landscaping in Washington, builders in western Washington are now required to stockpile existing topsoil during grading and replace it before landscaping, or bring in and amend soil, to meet the state's post-construction soil quality and depth standard, known as BMP T5.13.

The numbers are specific: at least 8 inches of soil, with at least 5% organic matter for lawn areas and 10% for planting beds. Where the native topsoil isn't there, the builder adds compost to reach that standard. Clark County publishes its own implementation procedure for builders on how to meet that requirement with on-site soils, including a minimum 8 inches of topsoil at the time of home completion, certified by a qualified soil professional.

💡

What to do with that: ask your builder how the soil depth on your specific lot was verified, and keep any documentation they give you. Exemptions and details can vary by project, so treat this as a good question, not a guarantee. And if you hire a landscaper, don't let heavy equipment compact or scrape that topsoil. The WSU Puyallup research cited in that guide found compost worked into the soil to about 8 inches improved soil health for more than five years.

What Will You Pay Extra For After Closing?

The list is longer than most buyers expect

Backyard grass. Often seed or sod beyond the front yard is on you, and sod gives an instant lawn but costs more than seed.

Fencing. Rarely included. If you have pets or kids, it's usually the first backyard project.

Irrigation. New plantings and sod need consistent water to establish. Our dry summers make this matter more than buyers expect.

Trees, shrubs, and extra planting beds. The builder's few foundation plants are a starting point, not a finished yard.

Patios, walkways, and retaining walls. The most expensive category, and where costs vary the most.

Window coverings and exterior lighting. Not landscaping strictly, but they land on the same post-closing list.

Costs vary widely. The sources I reviewed put a basic backyard of sod and a few plantings in the low-to-mid thousands, and a fuller project with a patio and irrigation far higher, but those are mostly national figures. For a real local number, get two or three bids before closing and add the total to your move-in budget, alongside the other costs in new construction closing costs, property taxes, and HOA fees. Run the combined total through the new construction home affordability calculator so it doesn't surprise you.

What Should You Know About Drainage Before You Landscape?

Plan water first, plants second

New Construction drainage

In our wet climate, where water goes matters more than what you plant. Before you add a patio, raised beds, or a new lawn, find out how your lot drains and whether it has drainage easements or stormwater features. Don't regrade, block swales, or build over anything you're not sure about. Ask your builder for the lot's drainage plan and what you can and can't build over.

Walk the yard after the first heavy rain and see where water collects. I cover that check in the first-year maintenance checklist. If water pools against the foundation because the grading was done incorrectly, that can be a builder issue, not a landscaping one, which is covered in what the builder's warranty covers. Document it and report it in writing early.

What Should You Ask Your Builder About Landscaping Before You Sign?

Seven questions, answered in writing

Exactly what's included in the front, side, and back yards, and is it seed or sod?

How was the topsoil depth on my lot verified, and can I have the documentation?

Is any irrigation, fencing, or exterior lighting included?

When will the landscaping be completed? Can it be finished after closing, depending on the season?

Who waters and maintains the new plantings until they establish, and are plants or sod covered by any warranty?

Does the community's HOA have landscaping or fence rules and deadlines for the backyard?

Is a landscaping credit or package available as an incentive? Builder incentives are worth asking about in this category too.

If you plan a fence, outdoor kitchen, or patio lighting, tell the builder before construction gets far along. Exterior outlets and a gas line stub are cheap to add early and expensive later, the same logic as the infrastructure choices in Design Center 101.

Bottom Line

Budget for the Yard Before You Close, Not After

Most builders give you a basic front yard and leave the rest to you. Get what's included in writing, ask how your soil depth was verified, find out how your lot drains, and collect a couple of local bids so the backyard doesn't land on a credit card. A good yard takes time, and a good start takes a few questions asked early.

Frequently Asked Questions

New construction landscaping, common questions

Does a new construction home come with landscaping?

Usually only the basics: grading, front yard seed or sod, and minimal foundation plantings. Backyard grass, trees, fencing, irrigation, and patios are typically a buyer expense, and it varies by builder, so confirm in writing.

Do builders in Washington have to provide topsoil?

In western Washington, WSU Extension reports that builders must stockpile and replace existing topsoil or amend soil with compost to meet a post-construction standard of about 8 inches of soil, with at least 5% organic matter for lawns and 10% for planting beds. Details can vary by project, so ask your builder how your lot's soil was verified.

Is sod or seed better for a new construction yard?

Sod gives an instant lawn but costs more and needs consistent watering to root. Seed is cheaper and works well for larger areas but takes longer to fill in. Many buyers sod the front yard and seed the back.

How much should I budget for landscaping a new build?

It varies widely. A basic backyard with sod and a few plants is typically in the low-to-mid thousands, while a fuller project with a patio, fencing, and irrigation can cost much more. Get two or three local bids before closing and add the total to your move-in budget.

Can I change my yard's grading or drainage?

Be careful. Some lots have drainage easements or stormwater features, and changing grading can cause water problems. Ask your builder for the drainage plan before regrading, blocking swales, or building over anything you're unsure about.
