Corona ADU: What You Need To Know

Corona ADU: What You Need To Know

If you’re looking to add a little more excitement to your life and current living situation, consider a Corona ADU. An ADU is an attached Dwelling Unit – typically, these are apartments built on top of or next to an existing single-family home. They offer the same great features and amenities as a traditional apartment, with the added bonus of accessing your backyard and house (or garage) from inside the unit.

What Are The Benefits of a Corona ADU?

A 2 story prefab ADU, or accessory dwelling unit, is a unique type of housing that has recently become popular in California. 

Some of the benefits of owning a Corona ADU include:

-They’re perfect for people with much extra space who don’t want to live in an apartment or condo.

-They’re affordable and easy to build.

-They can be used as primary or secondary residences.

-They allow you to customize your home exactly how you want it.

What are The Permits Required For a Corona ADU?

Corona ADUs typically require a permit from the City of Corona if the structure is less than 1500 square feet. The structure also needs a license from the County if it’s greater than 1500 square feet and a permit from the State if it’s within 100 feet of any public water or sewer line.

Some guidelines need to be followed when building an ADU, including ensuring that the dwelling meets all applicable fire codes and building standards.

When is The Best Time To Build a Corona ADU?

There is no definitive answer to this question as it depends on several factors, including the climate where the 2-story prefab ADU will be located and the specific needs of the homeowners. However, if you’re looking to build an ADU in a temperate climate, such as in California or the Northeast, the best time to do so is typical during the winter months. In hot climates, such as Arizona or Florida, building an ADU during the summer can be risky due to intense heat and humidity.

If you have questions about building an ADU, consult with your local building department and an experienced builder. Here are some tips to get started:

2. Get the proper permits. You’ll need tickets for structural elements (like the roof), mechanical systems (like HVAC), and exterior finishes (e.g., siding or trim). Speak to a qualified professional to help you determine which permits you to need and how much they’ll cost you.

3. Consult with a builder. If you don’t have the expertise or time to build an ADU, consider hiring a qualified builder. There are plenty of experienced professionals out there who can help guide you through the construction process, from design to finish work.
