New construction budget and home remodel costs: What to expect
If you’re just beginning your project, it’ll be a while before you have a budget in hand, but you’re no doubt wondering what to expect. Here’s an introduction to the expense categories you’re likely to find in your project budget.
The first time you see a budget for your new construction or remodeling project, you’ll want to be sitting down. Preferably at a table with your builder so you can ask all your questions. A budget for a custom home could easily climb into the seven figures and will no doubt include dozens of businesses, so it’s going to be complex.
However, taking the time to truly understand it will help you feel confident in your decision-making and your builder’s expertise. Ultimately it can build the foundational trust you’ll need to work together effectively.
Let’s take a look at the major categories of expenses associated with building so you’re not surprised when you look at your own budget for the first time.

Your guide to building a new home
What are the main expense categories in a project budget?
A typical budget for a new construction home or major remodel will be hundreds of line items long. This isn’t that. Instead it’s a look at the main categories of expenses you’re likely to see in a project budget with details about what’s typically grouped under each category. Keep in mind there will be costs associated with both materials and labor.
For example, the cost of windows includes the window units, installation materials (flashing tape, sealant, nails), any equipment rentals (like a boom), and the labor required to install the windows.
That level of detail can quickly become overwhelming, so we’ve deliberately kept this list simple, which means it’s not comprehensive. It’s an overview of what’s typical.
Site work
What’s included? Site work expenses may include things like:
- Building permit fee is what’s required by your local government in order to build a new home or remodel an existing home.
- Impact fee is what your local government charges to offset the impact a new home will have on infrastructure and services, like utilities, schools, public safety, and recreational facilities.
- Water and sewer inspection fees are charged by your local government when inspectors come to assess that all required conditions related to plumbing and sewer lines have been met.
- Architecture is the fee you pay your architect for designing your home and any other services rendered during the construction phase, like project management.
- Engineering is the fee paid to any engineers consulted.
What should I expect to pay my pros?
Builders’ fees vary, but a typical range is 10–20% of the total construction costs. Interviewing several builders before hiring will help you gain an understanding of the typical rate in your area — learn more about hiring a good builder. Architects’ fees vary, but 8–15% of the total construction costs is typical — learn more about hiring a good architect.
Foundation
What included? Foundation expenses may include things like:
- Excavation of the foundation and driveway as well as any grading required on the site.
- Foundation materials, like rebar, gravel, drainage tile, and the labor plus equipment required to construct the foundation.
- Concrete pouring for footings and slabs, concrete blocks used to build the foundation, and more.
- Retaining walls material, drainage materials, footings, and more.
- Backfill, or moving dirt and other materials in a way that supports the foundation, allows for drainage, and more will likely include equipment rental and labor costs.
Framing
What’s included? Framing expenses may include things like:
- Framing, or the materials needed to build the bones of the house, including lumber, nails and fasteners, weather resistive barrier (WRB), flashing, and more.
- Trusses, or the structural supports under the roof, are often bought prefabricated.
- Sheathing, or all that’s required to install the material, often oriented strand board (OSB), that’s layered over framed walls, the roof, and floors to provide structural stability, and more.
- Structural steel needed to support the framing, and could also include rental of equipment, like a boom.
Exterior finishes
What’s included? Exterior finishes may include things like:
- Exterior wall finish the actual siding, along with trim; and any extras, like shutters.
- Roofing materials, installation materials, and labor.
- Windows and doors products; installation materials, like flashing; equipment, like renting a boom; and the labor to install.
- Garage doors the doors themselves and all related details, like installing the openers.
How much will windows and doors cost?
We asked this question to a number of builders, and most felt allocating 10–15% of the construction budget was fairly typical. Of course, the actual cost will depend on your project’s design. For example, modern homes might be on the higher end because expansive glass is a signature feature of this style.
Major system rough-ins
What included? Major rough-ins expenses may include things like:
- Plumbing pipes to spigots and fixtures. Radon mitigation could fall here too.
- Electrical wiring to light fixture installation and any outdoor lighting systems.
- HVAC makes up the heating, ventilating and air conditioning systems as well as things like a kitchen hood vent, bathroom fan, dryer vent, dehumidifier, etc.
Interior finishes
What included? Interior finishes may include things like:
- Insulation
- Drywall
- Interior trim (baseboards, stairs, handrails, etc.)
- Glass and mirrors
- Painting and wallpaper
- Lighting
- Cabinets
- Countertops
- Tile
- Appliances
- Flooring
What’s value engineering?
Value engineering is the process of deciding how to balance functionality, quality, and cost by making changes to the design, methods, or materials originally planned for. Practically it’s what happens when a project is over budget, and it becomes necessary to reduce the square footage, swap in less costly finishes, and take other cost-cutting measures.
Builders and architects advise against value engineering the building envelope, or the components that protect your home from the elements, like your walls, windows and doors, roof, and foundation.
"[When value engineering] try to start with the things that can be changed later. Keep the building envelope and HVAC systems, and scale back on finish quality and square footage. Try to spread the cuts across all line items, rather than taking the quality out of a single component, like windows."Nick Schiffer, Owner of NS Builders
Remember, you can upgrade your countertops later or put up wallpaper after the fact, but it’s going to be a lot more costly to open up your walls and replace low-quality windows that failed prematurely.

Final steps
What’s included? Final steps may include things like:
- Landscaping
- Decks, patios, and porches
- Driveway
- Cleanup
Other costs
What’s included? Other costs may include things like:
- Land/lot is where you’ll build your home, of course. It’s a necessary prerequisite and not something the builder will provide, unless they’re also a developer.
- Job site conditions are the necessary items your builder will need during the project, like dumpsters, temporary utilities, temporary fencing, equipment rentals, etc.
- Upgrades like fireplace(s), a pool, hot tub, or sauna — really, the list is endless. Features like these will add complexity and cost.
