Commercial renovation in Ottawa — whether it's an office fit-out, retail buildout, restaurant kitchen reconfiguration, medical or dental clinic, or warehouse-to-mixed-use conversion — operates under a different rulebook than residential work. Tenant improvement allowances, lease constraint timelines, after-hours and weekend work requirements, accessibility compliance (AODA), and the layered building, fire, and health permits all influence project scope, schedule, and cost. This page covers the commercial renovation services Ottawa businesses need most, what to look for in a commercial GC, curr...

(3) Restaurant renovations — kitchen reconfiguration, dining room redesign, walk-in cooler/freezer install, code-compliant ventilation. (4) Medical and dental clinic buildouts — operatory rooms, sterilization areas, accessible patient flow, x-ray roo...
Speed-of-permitting matters more — every week of delay costs lease, payroll, and lost-revenue dollars. Commercial GCs structure projects to compress permit-to-occupancy timelines. After-hours and weekend work is common — most retail and office spaces require occupied-property work that limits noise, dust, and access during business hours. Code complexity is higher — commercial spaces trigger Ontario Building Code Part 3 (vs Part 9 for residential), full barrier-free design requirements under AOD...

Most occupied-property commercial work in Ottawa requires noise-restricted and dust-controlled work outside business hours. Common scheduling patterns: nightly 6pm-2am weekday work for high-traffic retail; full weekend access for office spaces (Friday 6pm to Sunday 8pm); 4-week phased closures for restaurants doing major kitchen work. Cost impact: after-hours premium typically 15-30% on labour rates. Plan dust barriers and HEPA negative-pressure containment for any work in occupied space — witho...
Customer-facing commercial spaces in Ontario must meet AODA (Accessibility for Ontarians with Disabilities Act) and Ontario Building Code Section 3.8 Barrier-Free design requirements. Common requirements: barrier-free path of travel from accessible parking through to main customer service areas, accessible washroom (or accessible route to one), 36" minimum door clearances, lever hardware on all customer-facing doors, accessible service counter sections at 34" maximum height. Older Ottawa commerc...
Per-square-foot ranges in 2026: office $80-$280, retail $100-$400, restaurant $250-$700, medical/dental $200-$400, light industrial $50-$120. Total project cost depends on square footage, scope, after-hours requirements, and AODA work needed.
Permits 3-6 weeks, design 4-12 weeks, construction varies dramatically by scope. Typical timelines: small office refresh 6-10 weeks construction; full office buildout 10-20 weeks; restaurant buildout 12-20 weeks; medical/dental clinic 14-24 weeks. After-hours and phased work extends timelines 30-60%.
Yes, virtually always. Building permit, plumbing permit, electrical permit via ESA, plus sector-specific approvals (Ottawa Public Health for food service, TSSA for refrigeration, AODA review for customer-facing space, fire alarm permit if system modified). Heritage approval if applicable.
TI is landlord funding provided to a tenant for buildout costs, typically structured as a per-square-foot allowance ($15-$60/sq ft is common in Ottawa) disbursed against documented invoices. TI accounting requires detailed contractor invoicing and often phased milestone disbursements that affect project cash flow.
Most office, retail, and even restaurant renovations can be phased to maintain partial operations. This requires careful dust barrier and noise containment work, after-hours scheduling, and a contractor experienced in occupied-property commercial work. Cost impact: 15-30% premium on phased/after-hours work.
