What if I want to make changes during the renovation?

Changes during renovation are completely normal - most homeowners make at least a few adjustments once they see the work in progress. The key is understanding how to manage changes properly to avoid delays, cost overruns, and potential disputes.

How Change Orders Work

Professional contractors use formal change orders for any modifications to the original scope. This written document outlines the specific change, additional costs (or credits), timeline impact, and requires signatures from both parties before proceeding. Never agree to verbal changes - this protects both you and your contractor.

In Ottawa's renovation market, typical change order costs include a 10-15% markup on materials and labor to account for scheduling disruption and procurement challenges. Minor changes like switching paint colors might have minimal impact, while structural modifications could add weeks to your timeline.

Common changes homeowners request include:

• Upgrading fixtures or finishes after seeing initial installations


• Adding electrical outlets or lighting once furniture placement becomes clear


• Modifying storage solutions in kitchens or bathrooms


• Adjusting secondary suite layouts during the permit review process

Budget and Timeline Impact

Most experienced contractors recommend setting aside 10-20% of your total budget for changes and unforeseen issues. In Ottawa's older housing stock (many homes built pre-1960), discovering outdated wiring, plumbing, or structural issues is common once walls are opened.

Timeline impacts vary significantly - cosmetic changes might add 1-2 days, while structural modifications requiring new permits could extend your project by 4-8 weeks. The Ontario Building Code requires permit amendments for certain changes, particularly in secondary suite conversions where egress windows, ceiling heights, or fire separations are affected.

When Changes Become Problematic

Avoid making changes during critical phases like electrical rough-in or permit inspections, as this can cause expensive delays. Changes to load-bearing walls, plumbing stacks, or HVAC systems typically require engineering review and permit modifications through the City of Ottawa Building Code Services.

Be decisive about finishes early - changing tile selections after installation begins often means paying for both removal and replacement costs. Similarly, structural changes discovered during demolition should be addressed immediately rather than deferred.

The best approach is thorough planning upfront, but when changes are necessary, work with your contractor to understand the full implications before proceeding.
