Ottawa renovation timelines run 2-3x longer than most homeowners expect. Here are realistic 2026 timelines from design to completion for every common project type, with Ottawa-specific factors that extend or compress schedule.
Design: 4-8 weeks (longer for custom cabinets). Permits: 3-5 weeks. Cabinet lead time: 8-16 weeks (custom 12-22 weeks). Construction: 4-8 weeks once materials arrive. Total: 16-28 weeks from initial design to completed kitchen. Faster is possible (semi-custom cabinets + simple layout) — 10-14 weeks. Slower for high-end custom: 28-40 weeks.
Design + product selection: 3-6 weeks. Permits: 2-4 weeks. Tile/fixture lead time: 4-8 weeks (custom 8-14). Construction: 3-5 weeks. Total: 12-20 weeks for primary bathroom; 8-14 weeks for powder room. Multi-bathroom projects can run partially in parallel if you have second bathroom available.
Design: 3-6 weeks. Permits: 4-8 weeks (longer if SDU — see SDU guide). Construction: 12-18 weeks for typical 1,000 sq ft finished basement; 20-32 weeks for full SDU with kitchen/bath. Total: 18-32 weeks (32-44 weeks for legal SDU). Inspections add 1-2 weeks between stages.
Design: 8-16 weeks (architect-led longer). Engineering: 3-6 weeks. Permits: 8-16 weeks (longer with Committee of Adjustment). Construction: 16-32 weeks depending on size and complexity. Total: 10-16 months from initial design to completion. Add 3-6 months for heritage or COA-required projects.
Cosmetic whole-house: 16-26 weeks. Major whole-house (kitchen + baths + finishes + some mechanical): 26-40 weeks. Full gut: 36-60 weeks. Heritage gut: 48-72 weeks. Most homeowners must move out for full gut: 8-14 month rental typically needed.
Peak season delays (April-August): 4-8 weeks longer due to contractor capacity. Winter exterior work limits: roofing/siding/concrete generally pause Dec-March. Permit office wait times: standard 3-5 weeks but spring 2026 has been running 5-8 weeks. Heritage district projects: +6-12 weeks for heritage review. Committee of Adjustment: +4-6 months for any variance. Supply chain: most kitchen/bath products at normal 4-8 week lead time in 2026, but specialty items (Italian tile, European appliances) ...
Total: 16-28 weeks from initial design to completion. Construction itself is only 4-8 weeks; the rest is design, permits, and cabinet lead times. Faster is possible with semi-custom cabinets and simple layouts (10-14 weeks).
Primary bathroom: 12-20 weeks total. Powder room: 8-14 weeks. Construction itself: 3-5 weeks. Lead times for tile, vanities, and fixtures dominate the schedule.
Typical 1,000 sq ft finished basement: 18-32 weeks. Legal SDU with kitchen and bathroom: 32-44 weeks. Permits and design dominate the early timeline; construction itself is 12-32 weeks.
10-16 months from initial design to completion. Permits often take 8-16 weeks (longer with Committee of Adjustment). Construction itself is 16-32 weeks depending on size. Heritage and COA add 3-6 months.
Combination of: permit office wait times (3-8 weeks), peak season contractor capacity constraints (April-August), supply chain on specialty products (12-24 weeks for European), Ottawa-specific freeze-thaw scheduling limits (no roofing/siding in winter), and the layered nature of building/electrical/plumbing/HVAC permit reviews.
