Cost Factors for Building Your Own Home
Key cost factors for building your own home include the size of your home, design type, building materials, interior features, customizations, and where you live.
Size
Plan on spending $60 to $110 per square foot for most self-builds. You might trim that to about $40 per square foot if you do a good chunk of the work yourself—or pay $200-plus per square foot when you bring in a full crew or pick high-end finishes. Labor and materials make up the lion’s share of the bill, and both swing with local market rates.
In general, building a small two-bedroom house costs between $93,000 to $155,000, while a three-bedroom home ranges from $248,000 to $310,000 . A four-bedroom house may cost anywhere from $388,000 to $465,000 or more.
| House Size in Square Feet | Average Cost Range |
|---|---|
| 800 | $48,000–$88,000 |
| 1,000 | $60,000–$110,000 |
| 1,500 | $90,000–$165,000 |
| 2,000 | $120,000–$220,000 |
| 2,700 | $162,000–$297,000 |
| 3,000 | $180,000–$330,000 |
| 4,000 | $240,000–$440,000 |
| 5,000 | $300,000–$550,000 |
Home Type
Two-story layouts usually cost more than single-story builds because adding an extra level means more time, labor, and safety gear. In contrast, tiny homes are some of the most affordable home types to build and make a great option for permanent living or as a guest house. Some popular home types and their average costs include.
| Home Type | Average Build Cost |
|---|---|
| Tiny Home | $45,000 |
| Modular Home | $270,000 |
| Log Cabin | $75,000 |
| Bungalow | $150,000 |
| Mid-Century Modern Home | $775,000 |
| Ranch-Style Home | $315,000 |
| Dome House | $175,000 |
Materials
Materials costs typically account for about 60% of your total construction costs. These costs will vary depending on the materials you choose—for example, highly durable and eco-friendly materials will have a higher upfront cost, although they may save you money on repairs and utilities costs in the long run.
Home Features
Interior elements like HVAC, cabinets, and appliances will add to your total cost. Some elements, such as HVAC, should be planned early so that your home designer can integrate them into the building plan. Most homeowners spend around $8,700 for an HVAC system.
Cabinets cost an average of $3,400 , while basic appliances for your home average $10,500 . If you’re worried about staying on budget, you can delay choosing some appliances like your refrigerator and laundry machines until home construction is done; however, it’s a good idea to plan the general size and style of appliances so you can ensure that your contractor builds enough space for everything you want to include.
Customizations
If you choose to design a custom home rather than build from premade floor plans, you’ll need to budget for architecture and design as well as contractor costs. In general, custom homes cost $200 to $550 per square foot. If you choose to design a custom home, hiring an architect generally ranges from $3 000 to $8,000, while a high-end custom home designer averages $30,000 to $50,000 per project.
Other Cost Factors for Building Your Own Home
In addition to the basic costs of building your home, it’s also important to account for other factors like labor, permitting, and exterior elements.
Prep
Working with raw land? Budget for tree, brush, or debris removal—and demolition if an old structure sits on the lot. Need excavation? Set aside another $80 to $5,050.
Labor
Even a DIY build still calls for skilled help from general contractors, plumbers, electricians, and architects. Some key labor costs include:
| Type of Labor | Average Cost |
|---|---|
| Architect | $6,700 per home design |
| Plumber | $45—$200 per hour |
| Electrician | $50—$100 per hour |
| General Contractor | $280,000 per home build |
Permits and Fees
Building permit fees can cost anywhere from $150 to $2,000, depending on where you live and the type of home you’re constructing. Check with your local permitting office before you begin designing your home to see if your area has any building restrictions.
You may also need to pay for water and sewer inspections, which cost around $5,000 . Additionally, once construction is complete, expect to pay between $2,000 and $3,800 to connect your home to services like water and sewage.
Exterior Elements
Exterior elements like fencing, landscaping, and driveways can be an effective way to make your home look complete. Fencing costs typically range from $10 to $30 per foot, while hiring someone for landscaping averages $70 to $150 per hour. Adding a gravel driveway costs around $1,500, while a paved driveway averages $4,400.
Other Structures
Installing a garage, deck, or other home structure will add to your total construction costs. Building a detached garage costs between $19,200 and $45,000 for a standard two-car garage, depending on where you live and features like automatic doors. Building a deck costs anywhere from $4,400 to $12,500 on average, with costs varying depending on the size of your deck and the materials used.
Building Your Own Home vs. Buying a New Home
Whether it’s more affordable to build or buy a home depends on several factors, primarily land costs. If you already own a plot of land, it’s usually more affordable to build your own home. This also gives you flexibility in terms of the size and style of your hom, so you can build something that fits your budget.
However, if you also need to purchase land, it may be more cost-effective to buy a finished home. This will depend on where you live and the types of homes available, as house costs vary significantly by state.
When calculating home building versus buying costs, it’s also important to consider custom features and additional living costs. If customizations are very important to you, it may be difficult to find a premade house that has everything you want, so building your own may pay off in the long run. On the other hand, most premade homes come ready to live in. When you’re building your own home, you’ll have to budget for where you’ll live during the construction process, which often takes around a year.
Budgeting for Building Your Own Home
Building your own home requires hiring an array of professionals and budgeting for materials, labor, and other building costs. However, there are several steps you can take to ensure this project meets your budget:
Consider purchasing a developed lot: Land that has already been used for residential purposes is usually cleared and includes utility hookups, which can save you time and money on preparation and municipal connections.
Use a premade design: Hiring architects and engineers to design a custom home plan can add roughly 30% to your total building costs. Premade designs are quicker and more affordable, and there is a wide array available, so you can find something that suits your style.
Avoid building a basement: Basements are a major hidden cost for homes. Excavating the land is costly, and they pose an insurance cost and repair risk in climates that are prone to flooding. Instead, consider adding an extra room if you’re looking for a little more space.
Talk to multiple pros: Contact several professional home builders in your area for quotes on building your home.
Include a contingency budget: Even with the best team, unexpected events like weather problems or shipping delays can prolong the building process. Budget roughly 20% of your total costs as a backup against the unexpected.
Build for the long term: While lower-quality materials cost less upfront, they can incur major repair costs in the long run. If you’re able, consider long-term features like energy-efficient heating systems and insulated windows to increase the lifespan of your home and save on utilities costs. Many municipalities also offer grants and subsidies for eco-friendly building, which can save you money on your total building cost.
