ADU Rental Income Calculator: How Much Can You Earn in Sacramento?

The Sacramento ADU Rental Market in 2026

Sacramento's rental market continues to favor ADU owners. With a vacancy rate below 4% and median 1-bedroom rents exceeding $1,500/month, ADUs represent one of the best passive income opportunities in the region. The key factors driving ADU rental demand include Sacramento's growing tech sector, state government employment, UC Davis Medical Center, and a steady influx of Bay Area remote workers seeking more affordable housing.

Current ADU Rental Rates by Area

Rental rates vary significantly based on location, ADU size, and finishes. Here are the current 2026 market rates for ADU rentals across the Sacramento and Placer County region. Studio/1-bedroom ADUs (400–600 sq ft) in Sacramento proper rent for $1,200–$1,800/month. Larger 2-bedroom units (800–1,200 sq ft) command $1,800–$2,500/month. In Placer County communities like Rocklin and Granite Bay, rates are 15–30% higher due to school quality and lower inventory.

Simple ROI Calculation

To calculate your ADU's return on investment, use this formula: Annual ROI = (Annual Rental Income − Annual Expenses) ÷ Total ADU Cost × 100. For example, a $200,000 detached ADU in Sacramento renting for $1,800/month generates $21,600/year in gross income. After expenses (property management, maintenance, insurance, vacancy allowance) of roughly $4,300/year, your net income is $17,300/year — an 8.65% annual ROI. This doesn't include property value appreciation, which typically adds another 3–5% annually.

Factors That Increase Your ADU's Rental Value

Not all ADUs are created equal. These features consistently command premium rents in the Sacramento market:

• Separate entrance and private outdoor space (+$100–$200/month)
• In-unit washer/dryer (+$75–$150/month)
• Central HVAC (essential in Sacramento's hot summers) (+$50–$100/month)
• Modern kitchen with full-size appliances (+$50–$100/month)
• Dedicated parking space (+$50–$100/month)
• Pet-friendly policy (+$25–$50/month pet rent)
• High-speed internet wiring (+$25–$50/month perceived value)
• Energy-efficient design (solar, insulation) — attracts quality tenants

Garage Conversion vs. Detached ADU: Income Comparison

Garage conversions cost $80,000–$150,000 and typically rent for $1,100–$1,600/month due to smaller size and shared-property feel. Detached ADUs cost $150,000–$350,000 but command $1,400–$2,500/month with better tenant retention. The ROI is often similar (7–10%), but detached ADUs offer higher absolute income and tend to attract longer-term tenants who treat the unit more like a standalone home.

Tax Benefits of ADU Rental Income

ADU rental income comes with significant tax advantages. You can deduct mortgage interest (if you financed the ADU), property taxes allocated to the ADU, depreciation over 27.5 years, maintenance and repair costs, property management fees, and insurance premiums. Consult a tax professional familiar with California rental property law to maximize your deductions.
