How to Build a Realistic
Renovation Timeline

Most homeowners come into a renovation thinking the timeline starts the day they sign the contract and ends the day they move back into the kitchen. That's the construction phase. It's about half the actual project.

The other half is everything before construction (design, permits, ordering) and everything after (punch list, warranty walk-through, ESA closeouts). When the full timeline is laid out, what felt like a 10-week kitchen project is actually 22-26 weeks from first call to closeout.

Here's how to build a realistic renovation timeline for an Ottawa project, what each phase actually takes, and how to spot a contractor's schedule that's wishful thinking.

The five phases of a real renovation timeline

Every renovation runs through these five phases in order. Compressing or skipping any of them creates downstream problems.

1. Discovery and design: measure-up, layout, selections
2. Estimate and contract: pricing, negotiation, signature
3. Permits and pre-construction: permits, ordering, scheduling
4. Construction: demo through punch list
5. Closeout: final inspections, warranty, holdback release

I'll walk through each one with realistic Ottawa duration ranges based on what we actually see across hundreds of projects.

Phase 1: Discovery and design (3-8 weeks)

Most homeowners underestimate this phase the most. It includes: initial site visit, conceptual layout, schematic design, design development, materials selection, and final drawings.

For a kitchen-only renovation with one designer iteration, expect 3-4 weeks. For a full-floor renovation with multiple iterations, 6-8 weeks. For an addition or new construction with structural design and engineering, 8-16 weeks.

Where this phase stalls: selections. Tile, hardware, lighting, plumbing fixtures, paint, cabinet finish. We supply selection sheets with deadlines for each. Homeowners who pick within the deadline window keep the project moving. Homeowners who treat selections as casual decisions add weeks.

The fix is a decision register: each selection has a date by which it must be locked, and the consequences of missing the date are written down. We use a simple spreadsheet that lives shared with the homeowner.

The renovation timeline is built before construction starts. The contractor who can't show you a decision deadline schedule is going to discover decision delays during the build, when they're expensive.

Phase 2: Estimate and contract (2-4 weeks)

Once the design is locked, the contractor builds a fixed-price estimate. This takes 1-2 weeks for a kitchen, 2-3 weeks for a larger renovation, longer for additions and structural work.

Then there's a back-and-forth on scope, allowances, and finishes that typically runs 1-2 weeks. Then contract review by the homeowner (often involving a real estate lawyer on larger-value projects) takes another 1 week.

What slips this phase: scope changes mid-estimate. Every time the homeowner adds or removes something during pricing, the estimator has to redo affected sections. We've had estimates take 8 weeks because the homeowner kept adjusting the scope. Lock the design before estimating begins, or accept that the estimate phase will stretch.

Phase 3: Permits and pre-construction (4-14 weeks)

This is the silent phase. Nothing visible is happening at your house. The contractor is filing permits with MyServiceOttawa, ordering long-lead materials, and locking the trade schedule.

City of Ottawa permit review times in 2026:

• Kitchen or bathroom permit (no structural): 2-4 weeks
• Basement legalization (under Bill 23): 6-12 weeks
• Side or rear addition: 8-14 weeks
• Coach house or ADU: 10-16 weeks plus committee of adjustment time
• Heritage conservation district: add 4-8 weeks for HCD review

Long-lead orders happen during this same window. Cabinet doors, custom windows, imported tile, specialty stone. The permit phase is also when these are placed so they arrive in time for installation.

What slips this phase: a permit that gets bounced back for missing details. Each round of revision adds 2-4 weeks. The first submission needs to be complete and accurate. A contractor who's pulled hundreds of Ottawa permits gets first-time approval most of the time. A new contractor often runs through 2-3 rounds.

Phase 4: Construction (varies by scope)

Build durations for typical Ottawa scopes, assuming a competent contractor with a real schedule:

Bathroom renovation

Standard bathroom: 4-6 weeks. Heritage home or full demolition with new plumbing: 6-9 weeks. Add 1-2 weeks if shower glass is custom-fabricated.

Kitchen renovation

Mid-size, no walls moved: 8-10 weeks. Kitchen with wall removal and structural work: 10-14 weeks. Full kitchen with custom cabinetry from in-house shop: same as the others (the cabinet shop runs in parallel).

Basement finishing

Basic finish (no bathroom): 6-8 weeks. With bathroom and bedroom: 10-14 weeks. Legalization for second-unit per Bill 23: 14-20 weeks including the additional waterproofing, fire separation, and egress windows.

Second-storey addition

Roof off, second storey on, finishes complete: 16-26 weeks. Significantly longer if exterior work has to wait for spring.

Side or rear addition

Foundation through finished interior: 14-22 weeks. Add 2-4 weeks for garage demolition or driveway impact.

Full-home renovation

Whole-house gut and finish: 26-40 weeks. Whole-house with addition: 36-52 weeks.

Coach house or ADU

Foundation to occupancy: 28-40 weeks including the full permit cycle.

The hand-off buffers nobody schedules

Inside the construction phase, every trade hand-off needs 1-2 buffer days. Drywall taper finishes Friday, primer goes up Monday, paint Tuesday. Without buffers, the moment one trade slips by a day the entire schedule cascades.

A real schedule includes:

• 1 buffer day between framing and electrical rough
• 1 buffer day between rough-in and inspection
• 2 buffer days between inspection and drywall (in case of revisions)
• 2 buffer days between drywall taping and paint primer (mud cure time)
• 1 buffer day between paint and trim install
• 2 buffer days between cabinet install and countertop template
• 10-14 days between countertop template and stone install

Sum the buffers and you get 2-3 weeks per renovation that look like "padding" but are actually realistic. A schedule without these buffers is a schedule that will slip.

Phase 5: Closeout (2-4 weeks)

The phase that's almost always shorter than expected by the homeowner and longer than expected by the contractor.

What happens here: punch list completion (small fixes, paint touch-ups, hardware adjustments), final inspections (ESA, building, plumbing, gas), final walk-through, manufacturer warranty registrations, document handover (drawings, permits, warranty certificates).

Then there's the 60-day Construction Act holdback period before the final 10% gets released. This is a legal requirement, not optional. The renovation isn't financially closed until that period ends.

For a typical kitchen, expect 2-3 weeks of closeout activity. For a larger project, 4-6 weeks. The contractor is mostly off site by week 1; the remaining time is paperwork and waiting periods.

The total timeline math

Let's add it up for two common Ottawa scopes.

Kitchen renovation (typical)

• Discovery and design: 5 weeks
• Estimate and contract: 3 weeks
• Permits and pre-construction: 6 weeks
• Construction: 9 weeks
• Closeout: 3 weeks
• Total: 26 weeks (about 6 months)

Side addition with kitchen tie-in

• Discovery and design: 8 weeks
• Estimate and contract: 4 weeks
• Permits and pre-construction: 12 weeks
• Construction: 20 weeks
• Closeout: 4 weeks
• Total: 48 weeks (about 11 months)

Compare those numbers to the timeline a homeowner usually walks in with: "we're hoping to be done in 3 months." The gap between expectation and reality is where the disappointment lives. Setting the right expectation up front protects everybody.

How to read the schedule the contractor gives you

When you receive a proposed schedule, check for:

1. All five phases included with separate dates
2. Permit phase explicitly carved out with realistic city review times
3. Long-lead items called out (cabinets, stone, tile, windows) with their order and arrival dates
4. Inspection windows after each major phase, with buffer days
5. Decision deadlines for any selections still open at signature
6. Substantial completion and final completion dates separately
7. Holdback release date 60+ days after substantial completion

If the schedule has all 7, you're working with a contractor who's run hundreds of these and knows where the real time goes. If the schedule is "12 weeks total, here's the start date," start adding weeks back.

The single biggest accelerator

Lock every selection before construction starts. Every tile, every fixture, every hardware finish, every paint colour. The faster homeowners can do this, the more compressed the construction phase becomes.

Our fastest projects are the ones where the homeowner spent two extra weeks in design making decisions instead of leaving them open. The construction phase ran 30% shorter because nothing waited on a selection.

The slowest projects are the ones where homeowners "want to see how it comes together" before deciding on tile or hardware. They arrive at the cabinet install with no countertop chosen, the countertop slot expires, the next slot is three weeks out, and the project loses a month for a decision that should have been made eight weeks earlier.

If you do nothing else from this article, lock your selections.
