Maximizing ROI: How an ADU Can Skyrocket Your Home’s Value in Denver, Arapahoe, Adams & Jefferson Counties
With Denver’s skyrocketing housing prices and a growing demand for affordable living spaces, building an Accessory Dwelling Unit (ADU) is one of the smartest real estate investments you can make. Whether you’re in Denver, Arapahoe, Adams, Jefferson, or Douglas County, an ADU can provide a massive return on investment (ROI) by increasing your home’s value, generating rental income, and making your property more attractive to future buyers.
1. Immediate Property Value Increase
If you own a home in Denver, Arapahoe, Adams, Jefferson, or Douglas County, adding an ADU can increase your property value by 30% to 50%.
✅ Example: A home in Jefferson County valued at $600,000 could jump to $800,000+ after adding an ADU, based on comparative home sales in the area.
🏡 Why? There’s an increasing demand for homes with additional living spaces, but a limited supply. Buyers are willing to pay a premium for a home that already has a fully-permitted, modern ADU ready to go.

2. Passive Rental Income: $3,000+ Per Month. If you live in Denver or surrounding counties, renting out your ADU could generate an additional $2,500 to $4,500 per month, depending on location.
📍 Estimated ADU Rental Income by County:
- Denver County: $3,500 – $4,500/month
- Arapahoe County: $2,800 – $3,800/month
- Adams County: $2,500 – $3,500/month
- Jefferson County: $3,200 – $4,000/month
This means you could earn an extra $30,000 – $50,000 per year—enough to cover your mortgage or retire early!
3. High Demand for Affordable Housing
Home prices in Denver and its surrounding counties are soaring, with median home values exceeding $600,000. Many young professionals, retirees, and families are struggling to find affordable places to live.
🏠 FACT: In Denver alone, the average home sells in just 9 days due to demand. With an ADU, you tap into a massive pool of renters who are looking for affordable alternatives to high mortgage rates.

4. Increased Resale Value & Marketability
When you sell your home, an ADU makes your property significantly more attractive to buyers.
🔷 Homes with ADUs sell 50% faster than those without because buyers recognize the built-in rental potential.
🔷 In competitive counties like Arapahoe and Jefferson, ADUs help properties stand out in a crowded market.
🔷 Multi-generational living is on the rise, making homes with ADUs highly desirable for families.
💡 Tip: If you hire a trusted ADU contractor in Denver, Arapahoe, Adams, or Jefferson, you increase your home’s resale value by $100,000+ almost instantly.
5. ADUs Provide Multi-Generational Living
ADUs aren’t just for renters! Many families build ADUs for aging parents, adult children, or visiting relatives.
🌟 ADU benefits for multi-generational families:
- Saves $4,000+ per month on assisted living costs.
- Keeps family members close but independent.
- Increases home flexibility and future resale value.

6. Denver’s Favorable ADU Policies
🏗️ Denver and surrounding counties are making it easier than ever to build ADUs.
In 2023, Denver relaxed its zoning laws to allow more homeowners to build ADUs. Many cities in Arapahoe, Adams, and Jefferson counties are following suit, recognizing ADUs as an important solution to the housing crisis.
🚀 What this means for you:
- Faster permit approvals for ADU construction.
- More financing options available for homeowners.
- Higher resale value due to increased demand.
