Build Your ADU in Anaheim: A Step-by-Step Guide for 2025
Accessory Dwelling Units (ADUs) have become a popular solution for increasing living space and generating additional income in Anaheim. However, the construction process can be complex due to local regulations and permit requirements. This guide provides detailed and up-to-date information to help you navigate the process of building an ADU in Anaheim, including pre-approved plans and express services that streamline project approval and construction.
What Are ADUs and JADUs?
An Accessory Dwelling Unit (ADU) is a secondary residential unit that can be either attached or detached from the main home. It provides complete, independent facilities for living, sleeping, eating, cooking, and sanitation on the same lot as the primary residence. ADUs are an excellent way to maximize your property’s use, offering additional space for family, guests, or tenants.
A Junior Accessory Dwelling Unit (JADU) is a smaller version of an ADU, with a maximum size of 500 square feet. It is created within the existing single-family home and must have its own exterior access. JADUs are ideal for those who want to add more living space without constructing a separate structure.

Financial Considerations and Financing Options
Building an ADU requires a significant investment. Consider the following financing options:
- Cash-Out Refinancing: Replace your existing mortgage with a new one and receive additional cash based on your home’s equity to fund your ADU construction. This method often offers lower interest rates, especially if your current mortgage rate is high.
- Home Equity Line of Credit (HELOC): A flexible credit line based on your home’s equity. While quick and cost-effective, it may come with a variable, higher interest rate.
- Construction Loans: Specific loans designed for ADU construction projects are available from some financial institutions.
- Grant Programs: California offers grants of up to $40,000 to reimburse ADU construction costs.
