Understanding the Total Cost of Building a Tiny Home or ADU

Before you apply for a loan or hire a contractor, it’s essential to get a full picture of the total costs involved. Beyond the structure itself, costs often include:

Site Preparation

Grading, excavation, or clearing land

Utility Connections

Water, sewer, gas, and electricity

Permits and Inspections

Local zoning and building code compliance

Foundation Work (For ADUs)

Concrete slabs or raised foundations

Design and Architecture Fees

If customization is needed

Appliances and Finishes

Flooring, cabinetry, and built-ins
For a permanent ADU, total costs typically range from $100,000 to $250,000+, depending on location, size, and complexity. A Tiny Home on Wheels (THOW) may cost less upfront, typically between $50,000 and $120,000, but there may still be costs associated with delivery, utility hookups, and site placement.

Evaluating Your Financing Options

Once you understand your budget range, the next step is to explore financing. Here are the three most popular loan options for homeowners financing a Tiny Home or ADU using their home equity:
Each of these options has different qualifications, rates, and structures—so it’s important to consult with a loan advisor who specializes in ADU and Tiny Home financing.

How to Estimate What You Can Afford

When calculating what you can afford, don’t just look at your loan pre-approval amount.

Factor in:

  • Monthly Cash Flow: Will you have new rental income or utility bills?
  • Long-Term Plans: Is this unit temporary, or will it serve a permanent purpose?
  • Tax Impacts: Will the unit raise your property taxes or qualify for deductions?
  • Maintenance and Insurance: New units mean new costs.
A simple way to get started is to use a loan affordability calculator or request a free consultation with an ADU loan specialist.

The Benefits of Smart Budgeting

By taking the time to understand your budget and financing options upfront, you’ll avoid common setbacks like project delays, underfunding, or overspending. More importantly, you’ll be able to move forward confidently knowing your investment aligns with your lifestyle, your property goals, and your financial future. 

Knowing what you can afford is not just about numbers—it’s about peace of mind. Whether you’re planning a cozy backyard cottage, an income-generating unit, or a comfortable place for aging parents, smart planning starts with knowing your financial limits and making informed choices.
