Building ADUs in Mission Valley?
Live in the heart of San Diego and want to add extra space? Let’s build you the perfect little home that fits your property and your budget!

We follow the City of San Diego’s official ADU rules in Information Bulletin 400—covering size limits, where you can place your ADU, and how to get your permit quickly. That way, your ADU is totally legal, looks polished, and the permit process is smooth.
Let’s make your “more space” dream a reality—fast, friendly, and fully approved!
Why Mission Valley is Perfect for ADUs
You picked a great place to live! Mission Valley is right in the middle of everything – close to downtown, great restaurants, shopping, and those trolley lines that make getting around super easy.
Here’s the cool part: your property could be worth a lot more with the right ADU. We’re talking about possibly adding 30% to your home’s value. Plus, you could rent it out and make some serious monthly income!
Here’s what Mission Valley homeowners get with an ADU:
- Extra money every month (renters pay $1,800-$2,500+ for nice ADUs here!)
- Your home becomes worth way more
- Perfect space for family who want to be close but independent
- Home office space that’s actually separate from your house
- Smart use of your property in this busy area
Whether you’re near Fashion Valley, living in Civita, or anywhere else in Mission Valley, we know exactly how to make it work on your property.
- Studio or One-Bedroom Cottage Perfect for young professionals who want to live in Mission Valley. Small but smart design makes it feel bigger than it is.
- Two-Bedroom ADU Great for families or roommates. More space means you can charge more rent too!
- Garage Conversion Turn that garage into a cool living space. Way more valuable than storing old boxes!
- Two-Story ADU Got a smaller lot? We’ll build up instead of out. You get more space and your renter might get better views.
- Inside Your House ADU We can turn part of your existing house into a separate apartment. Sometimes this is the smartest option.
- Hillside ADU Living on one of those Mission Valley slopes? No problem! We’ve built on tricky lots before.
