What You Need to Know about ADU Requirements in Corona, CA

Those Corona, California, homeowners who are considering building an accessory dwelling unit (ADU) are wise to do so. Also known as in-law apartments and backyard cottages, additional dwelling units (ADUs) are a novel approach to the housing shortage. A detached structure is one possible auxiliary structure for the main home, but another option is to convert an existing building into a secondary residence. To help you better understand accessory dwelling units (ADUs), I'll go over the history, current rules, and potential financing sources for ADUs in Corona, California.

Understanding ADU Size Limits

Detached ADUs can generally be built up to 800 square feet. However, approximately 391 cities and counties allow ADUs to be as large as 1200 square feet. Some places have specific restrictions, limiting detached ADUs to 1000 square feet for 2+ bedrooms, 850 square feet for 1 or fewer rooms, or 800 square feet due to bulk and massing limits.

Attached ADUs and converted structures have their own rules. For attached ADUs, the attachment should not exceed 50% of the existing square footage of the home. When converting an existing structure into an ADU, there are no size restrictions; the largest existing accessory structure in your jurisdiction determines the maximum size. Junior ADUs (JADUs) generally have a maximum size of 500 square feet when converted from existing space.

Navigating Local Rules and Guidance

While state laws provide general guidelines, it is crucial to check with your local city or county for specific rules related to your property. Understanding these local regulations can help you plan your ADU project effectively and avoid any potential setbacks.

Exploring California ADU Grants

CalHFA provides subsidies of up to 40,000 to cover pre-development expenditures, which further bolsters ADU building. Site preparation, building plans, permits, soil testing, impact fees, property appraisals, and energy studies are all potential components of these expenses. Homeowners in California may apply for grants to help defray the costs of building accessory dwelling units (ADUs).

Looking at Prefab ADUs and Backyard Office Pods

Prefabricated ADUs, or prefab ADUs, are becoming increasingly popular due to their cost-effectiveness (due to California ADU grants) and quick installation. These units are built off-site and then transported to your property for assembly. They can be a great option for homeowners looking to add extra living space without the hassle of traditional construction.

Backyard office pods are another innovative use of ADUs. With more people working from home, these small, standalone units provide a quiet and productive workspace just steps away from your main home. They can be customized to suit your needs and are a great way to separate work life from home life.

As you plan your ADU project, it is essential to stay informed about any new laws or regulations that may affect your plans. In 2024, California is expected to introduce new ADU laws, which could impact size limits, permitting processes, and other aspects of ADU construction. Keeping up-to-date with these changes can help you navigate the ADU construction process smoothly.
