Casita additions are becoming increasingly popular across Arizona.<\/a> Whether you\u2019re building for extended family, rental income, or extra living space, these small structures offer major value. But before you begin construction, there\u2019s one key system that needs your attention\u2014your septic.<\/p>\n

If your property runs on septic, adding a casita with plumbing will affect how your system operates. Arizona has specific guidelines to make sure septic systems are designed to handle the increase in daily use.<\/p>\n

How a Casita Addition Impacts Your Septic System<\/strong><\/h3>\n

Any time a casita addition includes plumbing like a bathroom or kitchenette, your property\u2019s wastewater flow increases. Arizona law requires your septic system to be sized appropriately based on that added flow. Even a small addition can push your existing system past its limit.<\/p>\n

The County will require updated site plans and flow calculations before approving your build. Depending on the size and location of the casita addition, you may need a larger tank, an expanded disposal field, or a brand-new system.<\/p>\n

Why a Separate System Might Be a Smarter Option<\/strong><\/h3>\n

A second septic system is often the right solution when the existing system is too far away or already near capacity. Running long sewer lines from a detached casita to the main home can add unnecessary expense and future headaches.<\/p>\n

In many cases, building a dedicated system for the casita addition makes more sense. It provides flexibility, simplifies maintenance, and keeps usage separated\u2014especially helpful if you plan to rent the space or live in it full time.<\/p>\n
