Pool house FAQs

What is a pool house?

A pool house is a structure separate from the home, located near the pool, which provides storage for pool equipment and essentials and a space to change without tracking pool water through your main house. Larger pool houses may also offer space to relax and entertain.

Depending on the size, a pool house may have one or all of the following amenities:

  • Bathroom

  • Shower

  • Changing area

  • Seating or lounge area

  • Game or recreation area

  • Kitchen

  • Extra living space

  • Guest bedrooms

  • Storage and shelving

How long does it take to build a pool house?

Building a pool house takes 2 to 3 months on average for a custom-built pool house with a washroom, changing room, storage, and seating. A custom pool house that acts as a guest house, complete with a kitchen, bathroom, bedroom, and living area can take 4 months to a year to construct.

Installing a prefabricated pool house or shed typically takes 1 to 3 days.

How much value does a pool house add to a home?

Most pool houses add value to a home by providing extra living or storage space and improving your property's aesthetic value. How much value it adds depends on the size and type of pool house you build and whether it appeals to potential buyers.

A pool house is typically a permanent structure that increases a property's total square footage. Non-permanent structures do not add square footage but may still add value for homeowners who spend a lot of time at the pool or entertaining outdoors.

Can I build a pool house on my property?

You can build a pool house on your property in most cases if you have the space for it. Most cities require a permit to build a pool house, though structures under 200 square feet may not require a permit in some areas.

Check your city building and zoning laws, and HOA regulations if applicable, to confirm the requirements.

How big is a typical pool house?

A typical pool house is 100 to 500 square feet, depending on the property size, layout, available space, and the pool house's intended use. Smaller pool house sheds provide a changing area and storage for pool equipment and essentials. Larger models may include a bathroom, shower, and lounge area.

Can you build a pool house yourself?

You can build a pool house yourself if you have the necessary construction skills. Most pool houses require the same expertise to build as regular homes. You'll likely need one or more permits depending on the size and features. Consult with a licensed contractor to ensure your structure is safe and up to code.

Getting estimates from pool house builders

Follow these guidelines when searching for a pool house builder:

  • Discuss options with friends or family members who have pools and pool houses.

  • Search for pool house builders who are licensed, bonded, insured, and have been in business for at least 5 years.

  • Check out their reviews on HomeGuide and Google.

  • Ask for a portfolio of past projects and local references.

  • Get an itemized contract and guarantee in writing before the work begins.

  • Work out a payment schedule and make sure the work is complete and has passed any required inspections before you submit your final payment.

Questions to ask

Ask the following questions to make sure you're hiring the right contractor to build your pool house:

  • Are you licensed, bonded, and insured?

  • How many pool houses have you built?

  • Can you provide references and a portfolio?

  • What is your lead time?

  • Can you match my house siding?

  • Do you do interior finish work?

  • What customizations do you offer?

  • Will you be doing the work, or do you use subcontractors?

  • What does the estimate include?

  • What extra costs typically come up when you're building a pool house like mine?

  • What do I need to do to prepare the property?

  • Do you handle leveling the yard and laying the foundation?

  • How much clearance do you need for material delivery?

  • What permits do I need, and do you handle the permitting process?

  • Do you have financing options?

  • Do you require a deposit, and if so, how much is it?
