Cost To Build A Duplex In Texas

Building a duplex in Texas can be a great way to get into the home-building business. If you’re looking for an investment that will pay off in many ways, this is it. You can build your duplex in any area of the state and still have a good income.

When you build a duplex, you’ll have two units with separate entrances but sharing some common areas. You can rent one side out and live in the other or sell both units as soon as you finish building them. This will allow you to make money from renting out one unit or both of them long after they’re built.

The cost to build a duplex in Texas can start at around $160,000 for a custom duplex home. If you’re looking for something more affordable, and want to save some money on the project, then consider building with a modular or manufactured home instead.

Duplex Home

A duplex is a building that has two units. A duplex home is great for investors because it provides them with a steady stream of income and allows them to build equity while they wait to sell their property.

Duplex homes can also be built on small lots, which makes them an affordable option for many buyers. In most cases, you will only need one garage for parking your car(s), saving you money on the cost of construction and land use fees.

Custom Duplex Home

A custom duplex is a home that has two separate dwellings built on the same lot and connected by a shared wall. This means you can design your own duplex house with your own unique floor plan, rather than just buying one of several pre-designed models. The average cost to build a custom duplex is $200 per square foot and ranges from $200-$500 per square foot depending on how much customization you want. The benefits include:

  • Your home will be unique and tailored to your personal needs.
  • You can save money by using existing materials instead of building everything new just for yourself.

Modular Duplex Home

Modular duplex homes are built in a factory and transported to the building site. They come with the same quality as conventional duplex homes, but they can be built in less time than conventional duplex homes.

Manufactured Duplex Home

If you’re looking for an affordable duplex, one option is to build a manufactured duplex or “modular duplex.” Manufactured duplex homes are built in a factory and then transported to the site where they’re assembled. They’re more affordable than custom-built homes, modular homes, and site-built duplexes.

Foundation Cost

Foundation Cost Varies Depending on Size

It’s important to note that foundation costs can vary greatly depending on the size of the duplex you’re building. The average cost for building a duplex is $70-90 per square foot, but this figure can be much higher or lower depending on the size of your home and what kind of foundation you choose. If you want your duplex to be well-built and sturdy, consider spending more money than average on foundations.

Foundation Cost Includes Concrete, Rebar, Excavation

In addition to considering how much concrete will be needed in order to build a large or small duplex, it’s also important to think about whether or not your project will require rebar (steel rods) during its construction phase. If so, consider adding an additional $7-$8 per square foot onto your overall budget for rebar materials alone. And don’t forget about excavation costs either: if there are trees on any part of your property where those trees need cutting down first before building begins then expect those costs as well.

Roofing Cost

The average cost of roofing installation in Texas is $3,000. The standard roofing material used in Texas is asphalt shingle, which costs $2,500 per unit. This includes all labor costs for installation as well as materials such as nails, screws and flashing tape. If you are looking for something different or more durable than asphalt shingle then consider tile or metal roofing instead. Tile and metal roofs both last longer than asphalt shingles but they come with a higher price tag – expect to pay an average of $8,000-$10,000 per unit installed on your home.

Flooring Cost

The flooring is one of the most important parts of a home, so you want to make sure that you get it right. There are many types of flooring to choose from and the cost will vary based on what type you select.

For example, Engineered hardwood floors can be less expensive than solid wood floors but they don’t offer the same level of durability or ease of installation as real wood boards do. Tile is less expensive than carpet but can be slippery when wet and difficult to clean if they’re not installed correctly by professionals. Carpet is great because it hides dirt well, absorbs sound, and provides cushioning underfoot (especially important if you have children). But carpets require regular professional cleaning in order for them not to look dirty after just a few months.

Lighting Cost

You will also have to consider the cost of lighting, which is typically a small part of your total project. The cost depends on how many lights you want, where they’re placed and what type of bulbs are used. Your best bet for saving money on this aspect is to buy energy efficient bulbs and install dimmer switches or motion sensors.

Framing Cost

Framing is the skeleton of a house. It’s what supports the walls, floor, and roof. As such, it’s one of the most important parts of building a home. The cost to frame can vary depending on how large your house is, but it will generally be between $5-$12 per square foot.

Timber framing and stick framing are two different methods that can be used for framing in Texas duplexes. Timber framing involves using thick timbers (usually 2x4s) for structural support instead of nails or screws which makes it significantly more durable than stick framing since less maintenance will be needed over time because there are fewer places where water can get into wood structures built with this method compared to those made with traditional materials like lumber boards or plywood sheeting which may warp due to moisture damage over time if not properly treated before installation (more on this below). On top of being structurally superior though – timber framed houses tend to last longer because they’re built much differently than other types too: rather than just having drywall panels covering everything up inside an outer layer thereof; instead there is usually some kind of insulation within these spaces between each joist so that no heat transfer occurs as easily through them either way.

Exterior Cladding (Siding, Stone, Brick) Cost

Exterior cladding is the material that covers your house—either siding, stone, or brick. The cost of exterior cladding depends on which type of material you choose and where you live.

Here’s a breakdown of some common types of exterior cladding materials:

  • Wood Siding: This is one of the most popular choices because it’s affordable and easy to install. There are many different types including vinyl wood, cedar shingles, pine board sheathing and so on. The average cost per square foot installed is $1-$3 depending on location and type chosen but can vary significantly depending on if there are any custom features involved like adding trim around windows etc.. The installation process takes about two days for an experienced crew working together efficiently; however some more complicated styles might take longer depending on how skilled they are at their job so keep that in mind when planning out your budget.

All Fixtures & Hardware Cost

All Fixtures & Hardware Cost

Fixtures are the things you see, like sinks and faucets. Hardware is the stuff that holds them together, like screws and bolts. This category combines the two into one cost so you can find out how much it will cost to build your duplex with fixtures and hardware included.

Electrical, HVAC, Plumbing Cost

Electrical, HVAC and plumbing costs can vary dramatically depending on the size of your project. The average cost to run an electrical circuit in Texas is $50 per month. If you have an existing house with a basement that needs to be converted into a duplex, this could add up quickly if the electricity is turned off during construction.

The average cost for installing new electrical service will be around $1,500-$2,500 which includes labor costs and materials such as conduits or wiring fixtures that are necessary for connecting fixtures outside your home (elevators). The same goes for adding additional outlets within each unit as well as running new lines from one unit into another; these are all things that require permits before they can be done legally so consult with local officials before beginning any work yourself.

Drywall & Paint Cost

  • Drywall & Paint: $5,000
  • Drywall makes up the structural walls of duplexes. The drywall contractor will install the drywall to create a flat surface, then paint it with a coat of primer and several coats of paint.

Mirrors & Glass Cost

Mirrors and glass in general are great ways to add light and space to a room. They can be used in many different ways, such as:

  • To make a small room look larger by creating the illusion of more open space.
  • To reflect light from windows or other sources, which will increase the amount of natural light in the room.
  • To create additional storage space by using mirrors on closet doors or cabinets.

Insulation Cost

For example, a single-family home in Dallas can have an insulation cost of $1.50 to $2 per square foot. However, in other areas of Texas such as Lubbock and Amarillo the typical cost may be higher—$3 to $3.50 per square foot. The reason for this is that the climate in these cities is much more extreme than Dallas’s moderate climate, which means there’s more variation between winter lows and summer highs. This means you need extra insulation to keep your home at a comfortable temperature year-round.

Cabinetry & Counters Cost

Cabinetry and counters are the most expensive part of a duplex. Cabinetry and Counters should be custom-made to match the rest of your home. They are usually made out of wood, but can also be made out of granite, marble or other materials.

Appliances Cost


  • Furnaces average $2,000.
  • Air conditioners average $3,500.
  • Refrigerators cost an average of $1,100.
  • Stoves cost about $1,200.
  • Washers and dryers come in at about $1,800 for a pair (if you don’t already own one).

Range hoods can run from $250 to over $5,000 depending on their size and features. Dishwashers are usually under $300 but may be closer to $600 for high-end models.

Windows & Exterior Doors Cost

Windows and exterior doors are important features that add value to your home. Window and door costs depend on the size, style, material, and location of your home. Buying windows in bulk can help reduce costs and installation fees. Custom-made windows are more expensive but offer more flexibility when it comes to functionality or design elements like glass panes or shutters. A benefit of customizing your window is that you can choose energy efficient glass such as double pane windows or insulated vinyl sashes which may qualify for tax credits if installed before December 31st 2019.

You can also use custom made doors to add curb appeal to your house by choosing a style that matches its architecture or interior design theme (i.e., rustic farmhouse). Installing a French door adds character while allowing light into dark spaces like basements (if they exist). There are many types of doors available such as sliding glass patio doors which allow natural ventilation during summer months while providing privacy during colder times; however their durability depends on how often they’re used so make sure there’s enough space between each one so air can circulate freely without hitting any surface since this could cause condensation inside otherwise.

Trim & Interior Doors Cost

Trim and interior doors cost depends on the type of doors, the material and the size. Trim and interior doors can be made from wood (pine, cherry), metal (steel), fiberglass or steel.

Trim refers to any moulded board or strip used to cover an opening in wooden framework around a door or window frame. The trim is usually painted after installation so that it matches the wall color.

Interior doors are generally solid but they’re also available as hollow core construction which contains a honeycomb core with insulation material inside it so that it doesn’t feel too heavy when closed and has thermal protection qualities (reduced heat transfer).

The most common styles for interior doors are framed panel doors, solid core with glass panels on either side etc., however there’s no limit when it comes down to design because each client has different ideas about what kind of look they want their home/apartment/duplex project will have.
