There are also additional variables that may or may not be out of your hands and can affect your project, such as change orders, delays, and inspections. We will discuss how some of them affect the process and how long some of its phases usually take.

Finding a Lot

Finding the right lot can take from a month to a couple of years, especially if there aren’t many options available in the area where you want to build your home in, whether it’s because there aren’t many unbuilt lots or the ones available aren’t just right for you budget. Moreover, finding a lot that meets your expectations in terms of size and type will also take some time.

Design Period

No matter if you decide on purchasing the lot first and then hiring an architect to design your house or do it the other way around, this step of the process will definitely take a while as you also need to find the right architect and interior designer to help you with the basics of building a house and the rest of the process.

Although it’s necessary to have the drawings ready for some interior details, you can start going over your preferences, style, and even make some decisions with your interior designer to save time in the process.

Plan Review and Permitting

This step of the process is highly unpredictable, as it depends on how efficient the municipality is in reviewing the plan and issuing the permits. In addition to the municipality, it’s probable that you will be subject to HOA plan review and approval if your lot is located within a homeowner’s association. Therefore, it’s quite helpful to hire an experienced architect and a professional home builder who are also familiar with the municipality and the homeowner’s association where your lot is located to understand what they will require during the plan review.

Choosing a Home Builder

An important aspect of choosing a builder is when you hire them. Despite most clients think that hiring a builder too early might limit them from the best price; however, not only does hiring them since the beginning accelerate the process, but it also saves you money in the long run. On the other hand, if you choose to bid the project to multiple general contractors, picking the lowest bid isn’t necessarily the best decision. Moreover, a fair bidding process could take from 3 to 6 weeks, which will delay the whole project.

Furthermore, making sure the contract is solid and clear for both parties is crucial. Therefore, it’s important to take a couple of days or even a week to set clear expectations and avoid misunderstandings between the home builder and the owner.

Lot Preparation

Before you begin the construction, some preparation of the lot is needed. How long this preparation will take depends on its original condition, as there could be vegetation or rocks that need to be cleared, for instance. Moreover, the soil condition might have an impact too as poor soils need extra preparation and compaction before the build can start. Commonly, lot preparation can take from 1 to 4 weeks as long as no problems arise.


The following step after the lot preparation is the actual construction, which starts with the underground utilities, such as plumbing. Afterward, it’s time to pour the foundation. These two steps take around 1-3 weeks. Then, you can start with the framing, which also includes the rough installation of casement or picture windows and sheathing. This part of the process might take around 12 weeks, but it depends on other factors like the size of the home.

Next, you can continue with the installation of electrical, mechanical, low-voltage wiring, and plumbing.
