  • Completing basic interior finishes yourself
  • Installing utilities during home addition projects

Financing Options

Since pool houses are usually considered additions or renovations, financing options include:

Cash-Out Mortgage Refinancing – Tap into home equity at low fixed rates with predictable payments. Only for major projects.

Home Equity Loan – Second mortgages based on equity allowing larger projects.

Home Equity Line of Credit (HELOC) – Revolving credit line giving flexibility for smaller projects.

Personal Loans – Unsecured so higher rates but fast approval for smaller builds.

Credit Cards – Reward points benefits but very high interest makes this a last resort.

Evaluate both rates and monthly payments when choosing financing to align with budget.

Regional Pool House Costs

Where you live also impacts what you can expect to pay when building a pool house:

Northeast and West Coast – Higher material and labor costs in states like New York, Massachusetts, Washington, and California push pricing 20-50% above national averages. Permits also cost more.

Southeast and South – More affordable building costs coupled with temperate weather reduces expenses 10-30% below national averages in states like Florida, Georgia, Texas, and the Carolinas.

Midwest Region – Mid-tier pricing aligned with national averages prevail through states like Ohio, Michigan, Illinois, and Missouri.

If possible, time projects to avoid peak demand seasons for additional cost savings.

Final Words

Building a pool house allows you to extend living space outdoors for entertainment and recreation. But undertaking such a substantial construction project carries major budget implications.

Having realistic expectations around pricing, outlining must-have features, finding ways to save through design and material choices, and financing the project sensibly are all keys to making your dream pool house a reality. What matters most is ending up with a beautiful, functional pool house that matches your needs and lifestyle.
