How Much Does It Cost To Build A House In Southern California

In the United States, Southern California (commonly referred to as SoCal) is a region of the country generally considered to be south of San Francisco and north of El Paso. It includes Los Angeles County and Orange County, which are composed of multiple metropolitan areas with their own distinct cultures and economies. SoCal also contains several other major metropolitan areas in addition to these two: San Diego County; Riverside County; San Bernardino County; Ventura County; Santa Barbara County; Imperial Valley; and Inland Empire or Greater Los Angeles Area.

The Three Phases Of Building A House In Southern California

The process of building a house in Southern California is broken down into three phases: land acquisition, architectural design, and construction.

The first phase is land acquisition. This involves determining if the land you want to build on is suitable for building; checking the title; acquiring a survey and making sure there are no easements or covenants that would affect your ability to build; hiring an engineer or architect to do plans for your home based on local regulations; getting permits from various agencies including the county planning department and fire department, where applicable.

What Goes Into The Cost Of Building A New House In Southern California?

When you’re building a new house, the cost of each step of construction is divided into three parts:

  • Materials and labor (which includes paying for materials and subcontractors)
  • Permits and inspections (which include building inspector fees, utility deposits, and fees, and permit fees)
  • Financing costs (loan interest, points or loan origination fees, etc.)


The cost of land varies depending on the location. In general, the more desirable a property is the higher its value. The price of land can be determined by the size of your lot and its location. For example, if you’re looking to build in an area that has lots of development and little space left for new construction (like Orange County), then you should expect to pay more for your lot than if you were building in an undeveloped area with plenty of available lands (like Riverside County).

Land prices are also subject to market trends and demand, specifically what type of homes people want to buy now and where those homes need to be built. Developers will often purchase large tracts of undeveloped land with an eye toward future growth potential before selling smaller pieces off as individual properties throughout time at varying prices based on demand factors like location or whether there’s limited availability nearby due to existing development plans already underway elsewhere in town.”

Architectural Design

Architectural design fees can range from $5,000 to $50,000. The initial design of the house and the site plan are included in these fees, as well as the construction documents and permit application.

The final price will depend on how much work has been done before you hire an architect and how detailed your plans are. In general, it’s best to be ready with drawings before hiring an architect so that he or she doesn’t have to waste time designing something from scratch.


Excavation is the process of removing dirt, grass, and other materials from a site in order to prepare it for construction. When you first start the construction process, everything needs to be leveled out so that your foundation can be properly laid down. There are two main ways that excavating can be done: by hand or using machinery. Hand excavation is typically used on sites where there is limited space and may require more time and effort than mechanized methods do.

Machine-assisted excavation uses specialized equipment such as bulldozers and excavators to dig up the material quickly without requiring as much human labor. The cost of machine-assisted excavation will vary depending on what type of equipment you use but tends to be cheaper than hiring workers who need full-time hours throughout the day while also paying them benefits like health insurance or paid vacations


Your foundation is the base of your house. It’s what will hold up the walls, floors, and roof. A poor foundation can result in cracks in your walls, leaks in your roof, and even structural damage to the home as a whole. If your foundation isn’t properly designed or installed, it could cost you thousands of dollars down the road when repairs become necessary.

So how much does it cost to build a house? Well, here’s where things start getting complicated, because there are so many factors involved in determining how much money will go into building a house from scratch (or tearing down an old one).


When you buy a house, you’re going to want to know that it’s safe and sound. That means the structure must be well-built, and that begins with the framing stage.

While there are many different types of framing materials (wood, steel, and concrete), they all serve the same purpose: providing a skeleton for your house. Framing is one of the most time-consuming parts of building a home – but also one of the most important steps in making sure that your house lasts for years to come.


Siding is the exterior covering of a building. It’s used to protect the structure of a building and can also be an important part of the overall appearance of a building. There are many different types of siding available for use on homes in Southern California, including vinyl siding, wood siding, and stone veneer. The cost varies depending on what type you choose because each comes with its own advantages and disadvantages.

The cost will depend on various factors such as size, quality, and materials used. Generally speaking though if you want something more expensive but durable then expect to pay more than if you just want something basic but less expensive

Windows, Doors, and Cabinetry

Windows and doors are an important part of any home. They provide the ability to let in light, air, and a view. A well-designed house will have windows that let in plenty of natural light and fresh air, which can be especially helpful for those with allergies or asthma. Windows also keep your home cool during the summer months when the temperature outside rises above 80 degrees Fahrenheit (24 Celsius).

Windows come in many different shapes and sizes, so you’ll need to decide which style fits your needs best. You can choose from casement windows (single hinged sash) or double-hung ones with top hinged sashes that open inwardly on both sides at once as well as fixed panels such as picture frames along with other types like fixed panels; bay/bow windows; sidelights; transoms (smaller versions of bow/bay) leaded glass panes etcetera…

When choosing between wooden interior doors vs fiberglass options there are several things to consider including price range availability maintenance requirements durability design aesthetic appeal sound absorption capabilities safety features ease of access maintenance requirements etcetera…


The cost of roofing is a big part of the total cost to build a house, and it’s a very specialized trade. The materials are expensive, so you want to get your money’s worth by having the best roofer on board. This is why it’s important to use an architect or designer who knows how to work with local contractors, rather than just hiring one directly from out of state.

The roofing materials include shingles (both synthetic and natural), asphalt tiles, slate tiles, and wood shakes/shingles made of cedar or redwood trees from Northern California forests (these are more expensive than their counterparts). Then there are two types of metal: steel and aluminum alloy roofs which are very durable but also come with higher costs due to their durability factor; they last longer than other types because they’re resistant to corrosion caused by weather elements like rainwater runoff etcetera.”

Exterior Trim

Exterior trim is the finishing touch to a house, and it can completely change the look of your home. Trim is made from a variety of materials including wood, metal, or vinyl; it’s installed around windows and doors, on the roof line and eaves of your home, and even in some cases along a garage door if you have one. Some types of trim are more expensive than others because they need special tools to install them correctly but all types still add up when you’re tallying up your total cost to build a house in Southern California.

You may want to consider building with pre-made trims made from composite materials like extruded polystyrene foam (XPS) or expanded polystyrene (EPS). These are lightweight yet durable materials that won’t add much weight onto your structure while maintaining their integrity over time thanks to their high resin content but they also tend not to last as long as traditional wood products such as dimensional lumber so these need are taken into consideration before making any decisions about what type works best for your needs.

If none of these options seems right for what you’re looking for then maybe try going with aluminum instead since it offers both affordability and still maintains durability throughout its lifetime.

Interior Finishes

  • Wood flooring: $1,000 – $2,000
  • Carpeting: $5 per square foot
  • Ceramic tile: $8 per square foot (in-grade) or $9 per square foot (above-grade)
  • Hardwood floors: $5 per square foot on average
  • Laminate flooring: Under $1 per square foot for high-quality products


Flooring is one of the most important aspects of a house, and it’s well worth spending some time thinking about what would look best in your new home. The cost depends on whether you’re installing wood, tile, or carpet flooring and whether you want to hire an installer or do it yourself. If you decide to hire an installer, make sure they are licensed and insured. A good installer will be able to show you samples of their work before starting any work in order for you to see their quality firsthand.

Bathroom Fixtures and Fitting

The cost of bathroom fixtures and fitting can range from $2,500 to $10,000+. The size and style of the bathroom will dictate how much you need to spend on your fixtures.

If you are building a new home, then your contractor will probably install all the fixtures during the framing phase. However, if you are renovating an existing house then you can either choose to buy them locally or online.

Before purchasing anything online just make sure that the store has a good return policy in case something goes wrong with the product after delivery.

Electrical Works

Electrical works cost depends on the type of electrical system you choose for your home, as well as the size and complexity of your home. An average house built with a single level might require about $3,300-$4,500 in electrical costs.

An average two-story house might require anywhere from $5,000-$7,000 depending on the number of outlets and switches needed.

If your home has a basement or attic space where lights are installed, then this will add more to your electricity bill because those areas need their own circuit breakers (around $1,200).

The type of lighting is also an important factor when calculating how much it costs to build a house in southern California: for instance, LEDs can save up to 85% over incandescent bulbs but come at an initial investment cost ($20-$30).


HVAC systems are a big part of the cost of building a home. They make up some 10-15% of the total construction budget, and depending on the climate, can be even more expensive. In warm climates such as Southern California, heat is a critical need for comfort and efficiency, but it’s also important to remember that air conditioning does not necessarily cool off your home as much as you think it does. The most efficient HVAC system for Southern California would be one that keeps your indoor temperatures at 76 degrees F with low humidity (35%). This will allow you to use less energy while keeping everyone happy inside their homes.

The cost of these systems depends on many factors: size; location; number of levels; type (forced hot water heat or natural gas); how efficient they are; etc., but generally speaking, they run around $10-$12 per square foot ($40-$50/sq m). So if you have an 1800 sq ft house (about 160m2), this means that installing an HVAC system could cost anywhere between $16k-$20k. If possible though – look into getting an energy-efficient unit installed instead: these can save money by reducing your monthly utility bills while still providing sufficient cooling power during hot summers

Landscaping Costs

Landscaping costs can vary widely, depending on the size of your property, its features, and what you have in mind for your landscape. You will also have to consider whether you want to do some of the work yourself or if it’s worth hiring professionals to take care of all of your landscaping needs.

Depending on where you live in Southern California, you could pay anywhere from $5 per square foot (for simple lawn care) to $100+ per square foot (for elaborate gardens). It’s important to note that homeowners usually pay these fees out-of-pocket; they aren’t included in the mortgage payment like closing costs are.

How Much Does It Cost To Build A House In Southern California?

The cost of building a house in Southern California depends on the size of your home and where you live. The average cost of building a house in Los Angeles is $3,200 per square foot. This includes labor, materials, and other construction expenses.

In Orange County, the average cost is lower at $2,700 per square foot.

The cost also varies depending on whether or not you’re building detached homes or apartments/condos (the latter will be cheaper).

Building a house is a process that can take years to complete and cost hundreds of thousands of dollars. However, the benefits of owning your own home far outweigh the costs you incur along the way. By knowing exactly how much it will cost before you start building your dream home, you’ll be prepared for when unexpected expenses that arise during construction.
