Before you begin building an ADU, it is crucial to understand the Oceanside ADU permit requirements:

What is an ADU?

An Accessory Dwelling Unit (ADU) is a secondary residential unit built on a single-family residential lot. ADUs are also called granny flats, in-law suites, or guesthouses. ADUs are typically smaller than the primary residence and can vary from 150 to 1,200 square feet. ADUs can be attached to the main house, detached, or built as a separate structure on the property.

Types of ADUs Allowed in Oceanside

Three types of ADUs have permissions in Oceanside: attached, detached, and garage conversion.

The attached ADUs get connected to the main house. You can build them above the garage, as an addition to the existing home, or in a basement that meets the height requirements.

Detached ADUs are separate units on the same property as the main house. You can erect them in the rear or side yard but not the front yard.

Garage conversion ADUs refer to turning an existing garage into a living space. This type of ADU is only permitted if the garage is legally allowed and meets the City's standards for development.

Requirements for Building an ADU in Oceanside

Before you begin building an ADU in Oceanside, you must obtain a city permit. The requirements for building an ADU in Oceanside are as follows:

  • Setbacks: The ADU must comply with all setback requirements for the zone in which it is located.
  • Height: The maximum height of an ADU is 16 feet.
  • Parking: One off-street parking space is mandatory for an ADU.
  • Plumbing: The ADU must have its own water and sewer connection unless it is a garage conversion.
  • Not for Sale: The ADU cannot be sold separately from the main house.

In addition to the abovementioned requirements, you must pay some fees to obtain an ADU permit in Oceanside. The fee subheadings for ADU permits in Oceanside are as follows:
