Hard Costs


Hard costs are all the material expenses directly related to the building of the house. These expenses cover the necessary labor and equipment. It also includes the materials for the roofing, flooring, framing, and concrete.

Depending on the project’s quality and location, home construction costs vary from city to city. A value-conscious home in Boulder could be built for $400 to $475 per square foot.

Homeowners should also take into consideration the monthly cost of maintenance for these utilities. 

Soft Costs


Soft costs are all the construction expenses that are indirectly related to the physical construction of the project. These expenses are primarily the permits, land costs, and architectural fees for the construction. Usually, these costs are to be settled even before the construction begins. 

Cost of the Land

Given the mountain landscape and great recreational activities, it is clear that land prices in this area may be higher than most in the region. In March 2021, the city recorded an average home price of $1,557,500. This is the highest median price recorded in Boulder Valley and northern Colorado. 

Lands that are much closer to amenities may be more expensive than those that are located on the outskirts of the city, or vice versa. According to the listing website Zillow, the average cost of land in the area is $532,359, averaging $41.02 per square foot. Currently, the most expensive lot is priced at $2,150,000 and is located on Paragon Drive near the edge of the city. The cheapest is a $24,999 lot on Riverside Drive in Lyons.

Permits and Other Fees 

To ensure the safety of the building, homeowners are required to apply for permits, which are then to be submitted to the local government for review. To apply, homeowners must first register to Boulder’s self-service portal and then find the right application form for their project. 

A building permit in Boulder is issued as a general permit. This means that a fraction of the total cost of the project must be paid according to the schedule of fees stated below. Unless otherwise stated in the general permit, electrical, mechanical, and plumbing fees are also required. The schedule of fees are as follows: 

Due to recent wildfires in the Boulder County, the county is now adopting new fire-resistant requirements for construction of new homes on the eastern grassy plains. According to news reports, building permits submitted on or after the 6th of June shall be required to meet the new requirements. 

Architecture and Design Fees

Plans for the design of a home almost always come first. There are many aspects of the build that are tied to the design. Without a plan, contractors can deviate from the design that homeowners initially wanted for their building. According to Boulder homebuilders, the average range is about 10 to 11% of the total construction cost. This estimate may increase or decrease depending on the scope and complexity of the project.

What Leading Custom Home Builders and Architects that Serve the Boulder Area Say


Boulder is an impressive city, to say the least. It is a great location for anyone who wishes to wake up with a view like the Rocky Mountains and basically be with nature. However, everything comes with a price.

Ryan Richards, Chief Financial Officer of Petra Custom Builders, said changes in supply and demand indicate higher new home construction prices. “Construction in the Boulder area is not likely to slow down, nor are prices likely to decrease for the foreseeable future,” he shared. “The components of demand are all high. The available land to build on is decreasing; builders have [a lot of] work in backlog (with low availability), and supply chain disruptions have been increasing commodity prices and lead times.” 

As the prices in the industry change rapidly, it is becoming more difficult for homebuilders to keep up with the pace. Richards added that it takes several months to complete the construction of the house, and the current market trend guarantees an increase in the final cost. “When starting the design process and targeting a given budget, we need to assume that in six months when the design is completed, the market alone will constitute a 10% addition to the construction costs.” 

Gettliffe Architecture owner Dominique Gettliffe shares similar sentiments in today’s complex property industry. Market fluctuations often affect homeowners who are planning to hire contractors for their own homes. “It is very challenging right now to project any construction cost.” She added that builders may ask to see the design first before giving any quote per square foot. Factors include the cost of materials, shortage of construction labor, and delays in both permitting and construction supplies are affecting the total cost of construction. To further help her clients in budgeting, Gettliffe is advising them to double their budget or reduce plans to meet the price increase. Although there are a lot of major increases in home construction costs, Gettliffe said that the city still has great demands for new homes.


The Future of Boulder’s Residential Construction Industry


Many factors affect a city’s housing market. One of the major reasons is its quality of life. Boulder’s overall atmosphere offers vibrant urban living while being able to come to a rural suburban area surrounded by a spacious landscape and a great climate. 

With supply and demand curves changing unpredictably and mortgage interest rates on the rise, home prices in Boulder could increase further in the coming years. As the city lacks affordable housing, many residents voice their concerns about the livability of the city itself. Although Boulder has its own program on this matter, the rising cost of expenses barely covers the other bills to be able to live comfortably. 

According to moving professionals, the state has seen demand for housing rise in 2020. People bought homes to accommodate the new work-from-home lifestyle. In 2022, this lifestyle continues to fuel the city’s housing market industry. A large portion of luxury custom homes in the area are bought by out-of-state buyers, specifically Californians. Among their reasons is the open landscape allowing breathing spaces and tranquility compared to the congested areas in their previous state. 

A resident may work from home in the morning and be greeted with the fresh mountain air in the evening. Boulder is a small city with a considerable amount of companies and a flagship university within its limit. It is no wonder many may find this akin to exclusivity and may plan to move in. With housing affordability farther beyond its reach, Boulder may focus its attention on the luxury housing market more than any other as it is the one currently in demand.
