Should you build a custom home or a home in a housing development in California?
Within the traditional design-bid-build construction delivery model, the owner is responsible for separately collecting bids and entering into contracts with two or more companies. In this way, the owner takes on the bulk of the responsibility for budgeting and contracting and may take a substantial amount of responsibility for the design process. Increased collaboration from the earliest stages of project development can lead to significant budget savings and more efficient schedule creation.
How Much Does It Cost to Build a House in California?
The conceptual phase involves taking a project need and advancing it to a general scope of work in support of a request for funding authorization. The major tasks are determining the project’s alignment/footprint, identifying stakeholders, and financial analysis to calculate either the benefit-cost ratio (public) or the return on investment and payback period (private). The conceptual phase ends with authorization of funding to advance the project’s design. In this phase, the project owner and estimators need to understand subsurface and environmental conditions, and to begin factoring in potential utility conflicts into the project schedule.
Minimizes Owner Risk
Project changes can lead to significant turmoil when multiple parties are involved under separate contracts, as each tries to shift the responsibility and increased costs off to the others. The combative nature of the change process can lead to delays and increased costs. Though relationships are fundamentally different between the two models, the steps involved in the project process look fairly similar. Let's look at the steps involved in the design-build process, its key advantages, and how it fits into the future of construction.
Cost to Build a House in California by House Style
Contractors on design-build are involved in the process from the outset and can consult or suggest changes to project designs very early in the process. On a design-bid-build project, the owner, the architects and engineers will work together to complete the design before a contractor ever bids on the project. During preconstruction, the owner will scope suitable sites and develop a rough design and budget.

Another study by the Construction Institute found that design-build projects had a 6% reduction in change orders, 102% faster delivery speed, and 3.8% less cost growth compared to design-bid-build. Design-build projects bundle designers and developers under the same contract. By bundling, you forgo the bidding process and chance to select a contractor based on price. Also, many design-builders won't begin a detailed design until they've been hired, making it harder to shop around. Most of the cost to build a house in California will come from the materials.
However, the overall cost will vary based on the size of the home and the quality and type of materials you choose throughout the build process. Material prices also vary considerably based on your location even within the state, as well as the demand and availability. Half of the cost to build a house in California will come from the materials. The below cost breakdown doesn’t include the price of land and permitting, which can increase your budget significantly depending on where you’re building your home. E-Bidding platforms like our own Bid Express have begun to incorporate scoring and evaluation features to make them flexible enough to use for both design-build and unit price contracts.
And contractors bidding on designs can be more confident that the subsurface utility conditions in the design match the reality they’ll find when they begin work. The design-bid-build project delivery method is a more multitiered approach than design-build. First, a design team works with the project owner to prepare the programming, design the project, and draft the contract.
If you accept their design proposal, you pay the agreed upon compensation for those services. If you don’t accept the design proposal and go on to the construction phase, you would only pay whatever was agreed upon for development of the design and other pre-construction services. As with any project delivery method, a comprehensive, fair, and unambiguous contract is critical to maintaining relationships and completing a successful project. A design-build must communicate and collaborate effectively, and cooperate with the owner and any subcontractors brought in later in the project phases. The Washington Department of Transportation (WSDOT) used the DBB project delivery method to improve a bridge at the Wenatchee River crossing.
Through the site selection process, the owner starts to form a picture of the project's scope, budget, and schedule to determine its viability further. During project conception, collaboration with design-build teams offers the advantage of pulling in the architects and engineers early to help shape the project. The design-build method is most often understood by comparing it with the more traditional design-bid-build method, which involves an owner entering into two main contracts. First, the owner contracts the architecture and design process to one firm, then enters a second contract with a general contractor to complete construction on the project. In design-build construction, an owner enters into a single contract to cover both the architectural design services and the physical construction of the build, streamlining the collaboration, communication, and coordination process.
When and if adjustments are necessary, each subcontractor or team must independently determine the most suitable course of action, taking into account factors such as project timelines, budgets, materials, and other processes. The Owner must manage two separate contracts which all-too-often creates an adversarial relationship between the designer and the contractor. If something goes wrong or an unforeseen circumstance requires changes, the designer and contractor blame one another for the cost overruns or schedule changes, often leading to litigation and delays which add to the project cost. In particular, design-build can be a great fit for projects without complex designs, such as infrastructure or road projects, and any building projects that the owner and design-builder have previous experience with. After receiving the bids, the original architect or engineer and the project owner evaluate them. Since submitted bids will not follow a uniform structure, the solicitation team may engage in an activity called bid-leveling, where they standardize bid formats as much as possible for more informed comparisons.
Design-build has grown in popularity recently, as many owners recognize its benefits for their projects. Recently, the design-bid-build method has been challenged due to the disadvantages listed above. Design-build is proving to deliver a better balance between cost and quality. Since architects aren't involved in the execution and implementation phase they lack insight on product availability, fluctuating market costs, and coordinating logistics. They may design a solution without considering the current price of copper, systems that may be backordered, etc.

Additionally, if you want a large lot or property spanning several acres, you'll unlikely find that with a housing development. Building your dream home in California means you'll need to consider all the necessary permits to complete the project, particularly if you want a pool or porch. For example, in downtown Napa and Santa Rosa, the average land listing is $900,000 to $1.5 million, respectively.
Many PDB owners select their design-builder before the design and project details are worked out (also called design-assist). In the PDB model, the owner works closely with the design-builder throughout all project phases, including design. We hope this article has provided you with a basic overview of these delivery methods to help you make the choice that is right for you and your project.
In the design-bid-build method, the project owner must oversee communications with the architect, engineer, construction firm, and sometimes others. This method simplifies communication by making the design-builder the single point of contact, removing much of the project burden from the owner’s shoulders. During the build phase, the general contractor manages the project, hires subcontractors and coordinates all construction activities. Their responsibilities include procuring materials and equipment, supervising the workforce and ensuring compliance with design specifications and project timeline. The original architect or engineer often acts as the owner’s representative, periodically providing updates on progress and inspecting the contractor’s work.
This only raises the importance for design builders of tackling utility challenges from the outset. The way that these phases are organized and overlap—and the different stakeholders involved in each phase—is the key difference between different types of project delivery methods. The different structures of a delivery method can have big implications for subsurface utility strategy.
