The ROI of a basement renovation in Toronto ranges between 65% - 75% ROI, with projects that create rental income can reach 140% - 200% ROI when factoring in both resale value and rental income. This means a well-planned basement renovation can significantly boost your property’s market appeal and generate ongoing cash flow.

Average ROI Percentages and Value Increase

• Standard Finishes (no rental unit)  -  A typical $60,000 investment often increases resale value by $39,000 - $45,000, equating to 65% - 75% ROI.
  
  
• Legal Apartment Suite  -  Adding a code-compliant rental unit dramatically improves returns, with resale value increases of $80,000 - $120,000 and potential ROI of 170% - 200%.
  
  
• High-End Finishes  -  Enhancements like a full bathroom, egress windows, or a separate entrance can push ROI to the upper end of the range.
  
  

Actual Statistics and Local Market Data

• Finished Basements in Toronto typically recoup 70% - 75% of costs at resale, according to 2025 regional reports.
  
  
• A legal rental suite can generate $1,700 - $2,400 per month in rent, with the average rent for an unfinished one bedroom in Toronto at $2,078 as of June 2025. This allows homeowners to recover renovation costs in 4 - 6 years.
  
  

Key ROI Drivers

• Legal Compliance  -  Meeting city standards for a secondary suite (egress windows, separate entrance, fire code) is the single most important ROI factor.
  
  
• Added Amenities  -  A full bathroom, additional bedroom, and quality finishes make the space more appealing to buyers and tenants.
  
  
• Neighbourhood Demand  -  High-demand areas of Toronto see stronger resale gains and faster rental uptake.

How a Legal Basement Apartment Boosts ROI in Toronto

Turning a basement into a fully legal apartment suite transforms it from simple finished space into a long-term income asset, making it one of the most profitable home upgrades in Toronto. The combination of immediate resale value increase and steady rental income can push overall ROI from the typical 65 - 75% range to 140 - 200% or more.

Why a Legal Apartment Suite Delivers Higher ROI

1. Dual Value: Resale + Rental Income

A code-compliant basement suite adds two layers of financial benefit:

• Resale Premium  -  Buyers are willing to pay a significant premium for a turnkey rental unit that meets city zoning and fire codes. Toronto real estate agents often cite a $80,000 - $120,000 boost in market value for homes with legal secondary suites.
  
  
• Ongoing Rental Revenue  -  Unlike a standard finished basement, a legal suite generates monthly cash flow, which buyers also factor into their purchase price, further inflating your resale value.
  
  

2. Market Demand and Scarce Rental Housing

Toronto’s tight rental market means well-designed basement apartments remain in high demand. With vacancy rates often below 2%, a self-contained suite with a private entrance, kitchen, and bathroom attracts reliable tenants and commands strong rents.

Revenue Projections and ROI Scenarios

Typical Rental Income:

• Monthly Rent: $1,700  -  $2,400 (depending on location and finishes)
  
  
• Annual Rent: $20,400  -  $28,800
  
  

Example ROI Calculation:
Suppose you invest $90,000 to convert a basement into a legal one-bedroom apartment.

Scenario A: Resale Only

• Added resale value: $110,000
  
  
• ROI from resale = ($110,000 ÷ $90,000) × 100 = 122%
  
  

Scenario B: Rental Income + Resale After 5 Years

• Annual rent: $24,000
  
  
• 5-year rental income: $120,000
  
  
• Total gain (resale + rent): $110,000 + $120,000 = $230,000
  
  
• ROI = ($230,000 ÷ $90,000) × 100 ≈ 255%
  
  

Break-Even Timeline

• At $2,000/month rent, your annual net (after 10% expenses) is roughly $21,600.
  
  
• You recoup your $90,000 investment in about 4 - 5 years, even before considering resale appreciation.

Factors That Influence Revenue

• Neighborhood: Central Toronto or areas near universities and transit hubs command the highest rents.
  
  
• Suite Design: A separate entrance, full kitchen, and in-suite laundry can add $200 - $400/month in rent.
  
  
• Utilities & Management: Expect to budget about 10 - 15% of rent for maintenance, utilities (if included), and occasional vacancy.
