adding a backyard cottage to your property isn’t just about extra space — it’s a smart financial move. In cities like Rancho Cucamonga and Ontario, homeowners are turning unused yards into income-generating assets through ADUs — also known as guest houses, tiny homes, or rental units.
With housing demand rising across the Inland Empire, an ADU can generate consistent ADU rental income California homeowners rely on. Whether you’re planning to rent it out full-time, use it for family members, or list it on short-term platforms, building a legal, high-quality unit is the first step toward long-term returns.
At WM Construction, we’ve helped over 127+ families since 2014 turn their backyards into valuable living spaces — all with clear contracts, free plans, and no surprises.
How Much Can You Earn from ADU Rental Income in California?
Rental prices vary depending on location, size, and finish quality, but here’s what recent data shows:
- A 500–700 sq ft ADU in Rancho Cucamonga rents for $2,200 – $3,000/month
- In Ontario, similar units average $2,000 – $2,800/month
- Energy-efficient, modern designs with private entrances attract higher occupancy and longer tenants
That means potential annual income of $24,000 to $36,000 — enough to cover a mortgage, support aging parents, or fund retirement.
But to get top dollar, your ADU must be well-built, code-compliant, and designed for comfort. That’s where experience matters.
We’ve been remodeling homes in Rancho Cucamonga and Ontario since 2014 — more than 10 years of real work, one home at a time. With over 10 years of experience, we know exactly how to design ADUs that rent fast and retain value.
Why More Homeowners Are Choosing ADUs in the Inland Empire
The shift toward accessory dwelling units isn’t a trend — it’s a response to real economic needs.
California has legalized ADUs to address housing shortages, making permits easier and construction faster than ever. Cities in San Bernardino County now offer streamlined approval processes, especially for detached units under 1,200 sq ft.
An ADU adds immediate square footage, increases your property value by up to 30%, and gives you flexibility:
- Rent it out for passive income
- House aging parents or adult children
- Use as a home office or creative studio
And because customer satisfaction is our #1 priority, every project we finish comes with a signed client form — proof that you’re happy before we walk away.
We get the job done right — not rushed, not delayed, not half-finished.
