Why Spring Is Ottawa’s Prime Renovation Season
Ottawa’s climate makes spring (April-June) ideal for many renovation projects:
- Ground thaws: Excavation for foundations, footings, and landscaping becomes possible
- Optimal temperatures: Concrete curing, exterior painting, and roofing work best in moderate weather
- Longer daylight: More productive work hours for outdoor projects
- Summer enjoyment: Complete outdoor living spaces before peak summer
- Fall completion: Larger projects can finish before winter
However, spring’s popularity means higher competition for contractors, longer permit queues, and potential material delays. Planning ahead is essential.

Planning Timeline: When to Start
For a spring 2026 construction start, here’s your planning calendar:
| Timeline | Action Items |
|---|---|
| November-December 2025 | Define project scope, set budget, research professionals |
| January 2026 | Hire architect/designer, begin architectural drawings |
| February 2026 | Finalize designs, get contractor quotes, select contractor |
| March 2026 | Submit building permit application, order materials |
| April 2026 | Receive permit approval, begin construction |
Key insight: Most homeowners underestimate how long the design and permit phases take. Starting 4-6 months before your desired construction date ensures you don’t miss the spring window.
Building Permit Lead Times in Ottawa
The City of Ottawa has target review timelines for building permits:
| Project Type | Target Review Time |

| Decks, porches, sheds, garages | 5 business days |
| Houses (detached, semi-detached) | 10 business days |
| Home additions | 10-15 business days |

Important: These are target timelines for complete applications. Incomplete submissions, revisions, or peak-season delays can add weeks. Always add buffer time to your schedule.
How to Secure a Contractor for Spring
Good contractors book months in advance for spring. Here’s how to secure one:
1. Start Early (3-4 Months Ahead)
Contact contractors in January for April/May starts. By March, the best contractors are fully booked.
2. Have Drawings Ready
Contractors provide more accurate quotes when you have professional permit drawings. Vague descriptions lead to vague (and often low-ball) estimates.
3. Get Multiple Quotes
Obtain 3-5 quotes to compare pricing and approach. Be wary of quotes significantly lower than others—they often lead to change orders.
4. Check References and Insurance
Verify WSIB coverage, liability insurance, and recent project references. Ask to see completed work similar to yours.
5. Sign a Detailed Contract
Include scope of work, payment schedule, timeline, and change order procedures. Never pay more than 10-15% upfront.
Budget Planning for 2026
Construction costs continue to rise. Here are typical 2026 budget ranges for Ottawa:
| Project | Estimated Cost Range |
|---|---|
| Deck (300-500 sq ft) | $15,000 – $40,000 |
| Basement finishing | $40,000 – $80,000 |
| Home addition (per sq ft) | $300 – $500 |
| Detached garage | $60,000 – $120,000 |
| Kitchen renovation | $30,000 – $75,000 |
| Bathroom renovation | $15,000 – $40,000 |
Budget tip: Add a 15-20% contingency for unexpected costs—especially in older homes where hidden issues may emerge.
