Our Story – From ADU Investment to Airbnb Co-Hosting

In 2023, my wife and I took a leap of faith. We pulled from our HELOC and transformed our three-car garage into a 450 sq. ft. Junior ADU in Fontana, CA. The project took about six months — much faster than building from the ground up since it was a conversion.

During construction, we faced a big decision:

• Should this unit become a long-term rental (12+ months)?

• A mid-term rental (30–90 days, sometimes 120)?

• Or a short-term Airbnb rental (2–3 nights minimum)?

After research (and a lot of late-night conversations), we chose the mid-term rental path. This allowed us to focus on 30-day stays without needing a short-term rental permit from the City of Fontana.

Of course, mid-term meant more investment. We spent an additional $10,000+ on appliances, furniture, and amenities to meet guest expectations. In total, between permits, construction, and furnishing, we invested nearly $100,000 into the unit.

We were nervous — would anyone even book?
To our relief, within a week of listing on Airbnb, our first guest arrived. Bookings continued to roll in, and while we hit bumps along the way, each challenge became a valuable lesson that made us smarter, stronger hosts.

Lessons We Learned

👉 Airbnb hosting today isn’t the same as 5–10 years ago. You can’t just snap phone photos and expect bookings. The competition is fierce, with professional investors spending heavily on design, staging, and SEO.

So why do some properties thrive while others struggle?
It all comes down to adaptability:

• Are you willing to invest in improvements that boost bookings?

• Are you ready to stay competitive in today’s hosting market?

We were — and it paid off.

• Last year, our ROI was 19.78%.

• This year, we’re on track for 21% — far beyond our expectations.
  
  

From Hosting to Helping Owners

The success of our ADU project inspired us to launch Yun Co-Host. Our experience taught us how to:

• Build equity through smart ADU construction.

• Maximize income with Airbnb co-hosting strategies.

• Deliver 5-star guest experiences that drive repeat bookings.
  
  

Now, we want to share what we’ve learned with other property owners. Whether you need help polishing your listing, boosting your booking rate, or even starting your own garage conversion project, we’re here to guide you every step of the way.

💡 Bonus: If you’re considering a garage conversion or ADU project in the Inland Empire, we offer a free consultation on how to start the permit process and avoid common pitfalls.

At Yun Co-Host, our story started with one garage and a dream. Yours can start today.

Our ADU Success Story

In 2023 and 2024, we took on one of the most rewarding projects of our lives: building two Accessory Dwelling Units (ADUs) on our property in the Inland Empire — a 1200 sq. ft. ADU (Unit 2) and a 450 sq. ft. Jr. ADU (Unit 3).

These ADU projects transformed not only our property, but also our financial future:

• 🏡 Without the ADUs, our home’s market value was about $810,000.

• 📈 With the ADUs completed, Zillow now estimates the property at $1.4M.

• 💵 Both units are fully rented and generating steady, consistent income.

This has truly been one of the best investments of our lifetime.

• Jr. ADU ROI: 19.78%

• ADU ROI: 7.19%
  
  

What We Learned from Building ADUs

As you’ll see in the videos above, both ADUs are located on the same single-family lot — clear proof that strategic property improvements can dramatically increase equity and passive income.

These ADU projects also shaped how we approach Airbnb hosting and co-hosting services in Fontana, Rancho Cucamonga, and across the Inland Empire. They taught us the importance of:

• Smart property upgrades that attract quality guests.

• Strong hosting practices that deliver 5-star experiences.

• Adapting to today’s competitive rental market.
  
  

From ADU Projects to Co-Hosting Services

The success of our ADUs is one of the main reasons we decided to step into the Airbnb co-hosting business. We saw firsthand how the right setup can maximize both property value and rental income — and we wanted to share that knowledge with other property owners.

So whether you’re:

• Looking for a trusted Airbnb co-host to manage your rental property, or

• Considering building your own ADU in Fontana, Rancho Cucamonga, or nearby Inland Empire cities to increase equity and passive income…

👉 We’d love to share our experience and guide you through the process.
