Your Backyard Is an Income Stream
If you're sitting on a backyard in Simi Valley, Thousand Oaks, or anywhere in Ventura County, you're sitting on income. That empty space behind your house isn't dead weight, it's a revenue stream. And in 2026, the math is getting better every month.

ROI: The Math That Matters
In Ventura County, your ADU pays for itself in 5 to 7 years even with conservative vacancy and maintenance assumptions. After that, it's pure profit. Better yet, your property value is also climbing.
Example: Simi Valley Standard ADU
- Build Cost: $150,000
- Monthly Rent: $2,000
- Annual Gross Income: $24,000
- Annual Net Income (after costs): $18,900
- Annual ROI: 12.6%
- Payback Period: ~6 years (with appreciation)
Property Value Increase: The Hidden Win
Research from UC Berkeley's Terner Center shows ADUs increase total property value by 15 to 25% above the cost of construction. Even at the conservative end, you're breaking even on construction costs immediately. Then rent covers everything else.
Tax Implications: What You Actually Keep
Rental income is fully taxable at your marginal rate (likely 32 to 35% combined federal + state in California). But deductions reduce taxable income: mortgage interest, property taxes, maintenance & repairs, depreciation, insurance, utilities, advertising.
Depreciation is a big win. On a $150,000 ADU, standard depreciation saves $1,000 to $1,500/year in taxes for 27.5 years. Work with a CPA for the best strategy.
