Pre-Approved ADU Program

The City of Laguna Niguel has established the Pre-Approved ADU Program to streamline the process of constructing accessory dwelling units (ADUs) within the City. Residents can choose from three pre-approved plan sets based on their preferences, featuring different sizes and architectural styles available for download. This page aims to assist users interested in taking advantage of the program by providing helpful resources, including handouts that explain the program, answer frequently asked questions, outline the process, and offer considerations to keep in mind when planning to construct an ADU.

Benefits of the Program

The Pre-Approved ADU program streamlines the process of obtaining permits and building an Accessory Dwelling Unit (ADU) for individuals who may not be familiar with construction and development.
Users can download the plans for free, which helps eliminate the need to hire design professionals.
Since the plans are pre-approved, the permitting timeline is shortened, and only the site plan and the final location of the ADU require review.
ADUs provide opportunities for older family members to age in place with nearby support while maintaining their independence.
