Driveway, landscaping and final steps: the last 6.5% of a new house

What the final steps include

The stage's share has stayed fairly steady over time, between 5.9% and 7.0% of construction cost in NAHB surveys since 2013.[1] But it varies a lot from one house to the next, because lot size, driveway length and how much outdoor living space you want change it far more than the house itself does.

Driveways: what moves the price

The driveway averaged $9,635 in the NAHB survey, but that number assumes a typical lot.[1] Its real cost depends on:

• Length and width. The biggest factor. A house set far back from the road on a rural lot can need a driveway many times longer than a suburban one, and a three-car garage needs a wider apron.
• Material. Gravel is usually the least expensive up front, asphalt sits in the middle and concrete and pavers cost more. Each has different maintenance needs.
• Base preparation. Soft soil, fill or poor drainage need more excavation and a thicker base.
• Slope. Steep driveways need more grading, drainage and sometimes retaining walls.
• Connection to the road. A new curb cut, culvert or apron in the public right-of-way usually needs a permit and may have to meet the local road authority's standards.

Landscaping, grading and drainage

Landscaping averaged $9,269 in the NAHB survey.[1] On a new build, it starts with final grading: shaping the soil so that water drains away from the foundation and off the lot without flooding neighbors. Then come topsoil, lawn or ground cover, plants, trees and any irrigation.

The factors that move the price:

• Area. Larger lots mean more grading, topsoil, seed or sod.
• Soil condition. Construction often leaves compacted subsoil; good topsoil may need to be brought in.
• Lawn method. Sod is instant but costs more than seed; seed is cheaper but needs time and water.
• Plants and trees. Larger specimens cost more and need more care to establish.
• Irrigation and lighting. Easier to install before lawns and beds are finished.
• Local rules. Some HOAs and towns require a minimum number of street trees, a front lawn or erosion control before final approval.

Ask the landscaper to start with a simple plan of the lot showing where water will go, where the lawn and beds will be, and where trees will be planted, keeping them clear of the septic field, the utility lines and the foundation. A plan on paper is cheap; moving a tree or a bed later is not.

Grading and erosion control are the parts not to skip. Bare soil around a new house can wash into the street, the storm drains and your foundation. Our guide to land clearing and site prep covers the stormwater rules that apply during construction.

Decks, patios and porches

Outdoor structures averaged $4,722 in the NAHB survey, a national average across homes with very different amounts of outdoor space.[1] Preferences vary by region. In the Census highlights for 2025, 24% of homes completed in the Northeast had a porch only, 11% a deck only and 4% both a patio and a deck, and 26% of detached homes sold in the Northeast had no outdoor features at all.[2]

Covered porches are built with the house and priced into the framing, roofing and finishes. Decks and patios can often be added later, but plan for them now: leave a door in the right place, run power and lighting, set the ledger or footings if needed, and grade the area so it drains. A deck high off the ground needs more structure, railings and stairs than a low patio.

Final clean-up and the punch list

Clean-up averaged $3,183 in the NAHB survey.[1] It covers removing construction debris, cleaning windows, floors, fixtures and cabinets, and sometimes a final dumpster haul. Ask whether your contract includes a professional clean before move-in.

This is also when the punch list happens: walking the house with the builder and listing every small fix, touch-up and adjustment. Take your time, use painter's tape to mark problems, and get a written list with dates. Some items, especially landscaping in winter, may be finished after move-in; get those in writing too.

Who does the work, and how to get it priced

Final steps are usually a mix of trades. The site contractor who did the clearing and excavation often does the final grading. A paving contractor pours or lays the driveway. A landscaper handles topsoil, lawn and planting, and sometimes irrigation and lighting. A deck builder or the framing crew builds decks and porches. The builder may manage all of them or leave some to you.

Because so many trades are involved, final steps are where gaps appear between bids. One builder includes sod on the front yard only; another includes seed everywhere. One prices a concrete driveway to the garage; another prices gravel to the property line. Ask every builder for the same written scope: driveway material, length and width; areas to be graded, seeded or sodded; the number and size of trees; any irrigation; and what clean-up is included. Our guide to comparing builder bids explains how to line them up.

Season matters too. Paving and planting depend on the weather. If your house is finished in winter, some of this work may be scheduled for spring. Make sure the contract says what will be finished, by when, and how any money held back for it will be released.

Small extras that add up

A handful of small exterior items are easy to forget because they are not in any one trade's scope. Check who is providing each of these: the mailbox and house numbers, gutters and downspout extensions, hose bibs, exterior outlets and lighting, a front walkway, steps to the back door, fencing, and a pad for trash bins or an outdoor HVAC unit. None of them is expensive on its own, but together they can add a noticeable amount at the very end of the job, when the contingency is lowest.

What you can defer, and what you should not

If the budget is tight at the end, some final steps can wait. But check first whether any of them are required for the certificate of occupancy, the lender's final inspection or HOA approval. Ask specifically about permanent stairs and handrails at doors, final grading, erosion control and the driveway surface, because local rules differ on which of these must be finished before a house can be occupied.

• Usually safe to defer: decks and patios that are not needed for access, ornamental planting, outdoor lighting, fences and upgraded driveway surfaces.
• Do not defer: final grading and drainage, gutters and downspout discharge, erosion control, and anything the inspector, lender or HOA requires.

The best protection is to budget the stage from the start rather than funding it from whatever is left. In the calculator, the Final Steps stage holds all five lines; replace the driveway and landscaping averages with quotes based on your site plan.
