Restoring a historic Ottawa home costs 20-40% more than renovating a modern home of the same size, reflecting the specialized materials, skilled labour, and regulatory requirements involved. A moderate restoration costs $100,000-$250,000, while a comprehensive restoration can reach $300,000-$600,000+ for large heritage properties. Ottawa has thousands of homes built between 1850 and 1940 in neighbourhoods like Sandy Hill, Centretown, New Edinburgh, Rockcliffe Park, the Glebe, and Old Ottawa Sou...
Ottawa has several levels of heritage protection that affect what you can and can't do with a historic home. Part IV designation (individual property) provides the strongest protection — exterior changes require a Heritage Permit from the City. Part V designation (heritage conservation district) applies to entire neighbourhoods and regulates changes to exterior appearance. Heritage conservation districts in Ottawa include: Centretown Heritage Conservation District, Lowertown Heritage Conservati...
Foundation issues are common in homes 80-150+ years old. Rubble stone foundations (common before 1900) may need repointing ($10,000-$25,000), waterproofing ($15,000-$30,000), or underpinning ($30,000-$75,000) to meet modern standards. These foundations were not designed for modern water management expectations. Knob-and-tube wiring must be replaced in any home being renovated. This original wiring system is a fire hazard and is not compatible with modern electrical loads. Full rewiring costs $8...

Options include restoring existing wood windows ($500-$1,500 per window — often more cost-effective and authentic than replacement), installing custom heritage-style replacements ($800-$3,000 per window), or installing interior storm windows ($200-$400 per window — preserves originals while improving energy efficiency). Exterior tri...
Historic restoration requires contractors with specific skills and knowledge. Not every renovation contractor understands heritage construction methods, appropriate materials, or regulatory requirements. Look for contractors who have completed heritage restoration projects in Ottawa (ask for a portfolio), understand lime mortar, plaster repair, and wood window restoration, are familiar with the City of Ottawa's heritage permit process, and can work with heritage consultants and architects. Heri...
Moderate restorations cost $100,000-$250,000, comprehensive restorations $300,000-$600,000+. Historic restoration costs 20-40% more than standard renovation due to specialized materials, skilled labour, and heritage compliance.
If your home is individually designated (Part IV) or in a Heritage Conservation District (Part V), exterior changes require a Heritage Permit. Interior work is generally unrestricted. Check with Ottawa Heritage Services for your property's status.
Restoration ($500-$1,500 per window) is often preferred — it preserves authenticity and is frequently required by heritage guidelines. Adding interior storm windows improves energy efficiency while keeping the originals intact.
