IS IT WORTH IT TO ADD AN ADU?

Adding an Accessory Dwelling Unit (ADU) to your property isn’t just about extra space—it’s a smart investment that can significantly boost your income and property value. Whether you rent it out short-term or long-term, an ADU offers steady cash flow that can help cover mortgage payments or fund other expenses.

In San Diego’s competitive housing market, demand for rental units is high. An ADU gives you a flexible way to meet that demand while maximizing your property’s earning potential. Plus, many homeowners see an impressive return on investment—often recouping costs within just a few years through rental income alone.

Beyond immediate earnings, ADUs also add lasting value to your home. When it comes time to sell, buyers often pay more for properties with an additional, self-contained living space.

Even if you choose to live in the ADU or offer it to family, you’re freeing up your main house, potentially saving on housing costs or enjoying multigenerational living with privacy.

With relatively low construction costs compared to building a new home, plus streamlined San Diego permitting processes, now is a great time to consider an ADU. It’s a win-win: extra space that pays for itself.

Ready to start building your income? Let’s talk about making your ADU project profitable and hassle-free.

WILL I GET CAUGHT UP IN PERMITS?

Navigating the permitting process for an ADU can seem daunting, but in San Diego, recent changes have made it much easier and faster than before. The city has streamlined regulations and offers clearer guidelines to help homeowners get their projects approved smoothly.

While any construction project involves paperwork and inspections, ADU permits are now prioritized to encourage more affordable housing options. Many homeowners find that with the right planning and an experienced team, securing permits is straightforward and hassle-free.

That said, understanding local zoning rules, setback requirements, and building codes is key to avoiding delays. Working with professionals who know San Diego’s permitting process can save you time and stress, ensuring your ADU meets all standards from the start.

Keep in mind, minor hurdles may pop up depending on your property’s specifics, but overall, the process is designed to be manageable—even for first-time builders.

In short, while permits require some effort, they’re far from impossible to get. With good guidance and preparation, your ADU project can move from concept to reality without headaches.

But we are here to help, we are experts in navigating permits and working with the city to ensure you get the home of your dreams!

CAN I FINANCE MY ADU?

Yes you can! Building an ADU is a smart investment, and there are plenty of financing options to help make it affordable. From home equity loans and construction loans to specialized ADU financing programs and government grants, there’s a solution for almost every budget. Many lenders now recognize the value ADUs add, making it easier to qualify. Plus, rental income from your ADU can help offset loan payments. With the right plan, financing your dream ADU is easier than you think!
