Budget and Financing for your next Custom Home in Utah.

A project manager examines the financial plans for a new home, ensuring every detail aligns with the budgetary constraints.

When I meet with potential clients one of the largest concerns I get is wether or not I will be able to stay on budget because with financing a new costum home build comes the following questions:  How much does it cost to build a custom home per square foot? How accurate is the initial estimate—can I expect cost overruns? How do allowances work, and what can make my project go over budget? What financing options are available for building a custom home? Are there ways to save money without sacrificing quality?

So with that it mind, I thought I would answer each one of these and throw in a bonus answer. Here is my best shot...

1. How much does it cost to build a custom home per square foot?

The honest answer is: it depends.**

The cost per square foot varies widely based on:

    •    The complexity of the design

    •    The level of finishes and fixtures you choose

    •    The site conditions (for example, whether the lot requires excavation or has utility access)

In our area, most custom homes range anywhere from $310 to $700+ per square foot.

To give you a more precise estimate, we start by discussing your vision, style, and priorities. After developing preliminary plans and specifications, we’ll provide a detailed proposal tailored to your project.

2. How accurate is the initial estimate—can I expect cost overruns?

We put a lot of care into providing accurate estimates up front. However, it’s important to understand that certain factors can affect the final cost:

    •    Changes you request after construction begins (called “change orders”)

    •    Unforeseen site conditions (for example, unexpected rock or poor soil)

    •    Fluctuations in material or labor costs

We work closely with you to define clear specifications and allowances to minimize surprises. Regular budget updates during construction help you stay informed and make decisions proactively. Our goal is transparency and no hidden fees.

3. How do allowances work, and what can make my project go over budget?

Allowances are pre-set budget amounts for items you haven’t selected yet—like cabinetry, flooring, or lighting fixtures. For example, your contract might include a $50,000 allowance for cabinetry. If you choose options exceeding that amount, the difference is added to the project cost.

The most common reasons projects go over budget are:

    •    Upgrading materials or finishes beyond the allowances

    •    Making design changes after construction has started

    •    Unexpected site-related issues

    •    Expedited timelines requiring overtime or rush orders

To avoid overruns, we guide you through selections early and help you understand how each choice impacts the budget.

4. What financing options are available for building a custom home?

Most clients use a construction loan, which is a short-term loan that covers the building phase. Here’s how it usually works:

    •    Your lender provides funds in stages (“draws”) as construction progresses

    •    You pay interest only on the funds disbursed

    •    When the home is complete, the loan converts to a standard mortgage (sometimes called “construction-to-permanent financing”)

We’re happy to recommend local lenders experienced in custom home construction and can coordinate directly with them to streamline the process.

5. Are there ways to save money without sacrificing quality?

Yes—smart planning makes a big difference. Here are some strategies:

    •    Simplify the design: Reducing complexity in the footprint and rooflines can save significantly.

    •    Prioritize must-haves vs. nice-to-haves: Focus your budget on spaces you’ll use most.

    •    Select cost-effective finishes: There are many materials that offer durability and style without a premium price.

    •    Make decisions early: Late changes can be costly.

    •    Work with an experienced builder: Careful project management and trusted trade relationships help control costs.
