FAQs for building service design service projects in Diamond Bar, CA

Most municipalities require a building permit before you put up a pool house. Rules and fees vary widely depending on where you live and the local regulations in your area. Check with your local building department or general contractor early on in your pool house project, so permit costs and timelines don’t catch you off guard.

If you’re building a custom pool house, you can expect the entire process to take two to three months from the design phase to the end of construction, or even as much as a year for very large or complex pool houses. If you’re installing a prefabricated kit or shed, the process is much faster, averaging one to three days.

A pool house is generally sized between 100 square feet and 800 square feet, which means its dimensions directly reflect its intended functionality. A compact pool house, measuring 100 to 150 square feet, serves as an efficient storage or utility space, while a pool house of 300 square feet or more offers a comfortable room for changing, relaxation, and socializing. The size you choose depends on the intended use and design of your outdoor space, ensuring that the structure meets your lifestyle needs.

The common types of pool houses include guesthouses, standard pool houses, and sheds. A guesthouse is a small lodge adjacent to the primary home that provides overnight accommodations with essential amenities. A standard pool house is built near the pool to offer storage, changing facilities, and a relaxation zone. A shed is a simple structure designed for storing pool equipment and garden tools. Each type serves a distinct purpose and enhances your outdoor living experience.
