Thinking about adding space, value, or flexibility to your property? A custom-built Accessory Dwelling Unit (ADU) may be exactly what your home—and your lifestyle—needs.

At St. Paul Contracting, we help Southern California homeowners design and build ADUs that are not only beautiful and functional, but also packed with long-term benefits. Whether you're housing family, generating passive income, or increasing your home's value, an ADU is a smart move.

Newly built ADU in Southern California with private entrance, modern design, and rental potential, constructed by St. Paul Contracting. — From added income to more room for family, ADUs deliver flexibility, privacy, and long-term value. Let **St. Paul Contracting** design and build the perfect ADU for your property.

💰 1. Increase Your Property Value

One of the biggest reasons homeowners build ADUs is the significant increase in property value. In California, homes with permitted ADUs can sell for up to 30% more than those without.

An ADU adds finished square footage to your lot, which immediately boosts your home's market appeal and resale value—especially in competitive areas like Rancho Cucamonga, Ontario, Upland, and across Southern California.

💸 2. Generate Monthly Rental Income

With rising rent prices, an ADU can provide steady, passive income. Whether you’re renting to long-term tenants or listing on Airbnb (where permitted), an ADU can offset your mortgage or become a new income stream altogether.

Many homeowners are now earning $1,500 to $3,000/month renting out ADUs—making it one of the most profitable home improvements available today.

👪 3. A Private, Comfortable Space for Family

Have aging parents, returning college students, or guests that visit often? ADUs offer a private, self-contained living space right on your property—perfect for multigenerational living without sacrificing independence.

ADUs are also a popular option for home offices, art studios, or guest suites, giving your family more room to breathe without a full-scale home addition.
