New Build Inspection in Calgary: PDI, Possession, and Warranty Strategy

Calgary's new-build market produces excellent homes — and predictable categories of deficiency. This guide explains how the builder PDI differs from an independent inspection, how to time each, and how to use the inspection report as a warranty document.

Direct answer: do new homes need inspections?

Yes. Even reputable Calgary builders ship homes with deficiencies — finish issues, mechanical balancing, attic ventilation, grading, and trade-coordination items. The builder PDI is a walkthrough that the builder controls; an independent inspection is your own technical record. Both are useful. Both have a place. Combined, they give you the documentation you need to enforce the Alberta New Home Warranty.

PDI vs independent home inspection

  • PDI — builder-led walkthrough at possession. Documents finish items the builder agrees to address.
  • Independent inspection — third-party technical review. Documents defects and recommends remediation regardless of builder agreement.
  • PDI tends to capture cosmetic deficiencies. Independent inspections add mechanical, ventilation, envelope, and safety items.
  • Both can run at pre-board / pre-drywall, pre-possession, and 11-month warranty milestones.

What new-build inspectors often look for

  • Roof — flashings, vents, and finishing at penetrations.
  • Attic — insulation depth, ventilation balance, bath fan terminations.
  • Exterior — cladding, sealants, decks, grading, window-well drainage.
  • Mechanical — furnace start-up, ducting, HRV/ERV operation, water heater venting.
  • Plumbing — fixture function, drain operation, shut-off accessibility.
  • Electrical — panel labelling, GFCI/AFCI sampling, smoke/CO alarms.
  • Finishes — drywall, paint, trim, flooring, tile, cabinetry alignment.
  • Safety — guardrails, handrails, egress, garage fire-separation.

Seasonal Calgary issues in new builds

Calgary winter possessions create predictable inspection limitations. Snow on the roof and frozen ground hide grading, drainage, and the lower courses of cladding. The AC cannot be tested below 16 °C. Final landscaping and exterior trades may not yet be complete. A good inspector documents these seasonal limitations and recommends a follow-up exterior review in spring.

Warranty documentation strategy

  1. Save every PDI form, builder email, and trade callback.
  2. Photograph every deficiency with date stamps.
  3. Group findings by trade — drywall, HVAC, plumbing, electrical — for the builder's coordinator.
  4. Book the 11-month independent inspection 30–60 days before the one-year deadline.
  5. Submit the inspection report to the builder in writing and copy your warranty rep.

Common new-build deficiencies

  • Bath fans terminating in the attic instead of through the roof.
  • Insulation gaps at attic perimeters and behind kneewalls.
  • Negative grading or poor downspout discharge.
  • Furnace ducting with crushed or disconnected runs.
  • Missing AFCI/GFCI protection on required circuits.
  • Drywall, trim, and tile finish deficiencies after settlement.

Frequently Asked Questions

Do new homes need inspections?
+
Yes. New does not equal defect-free. An independent inspection complements the builder PDI and creates a documentation record useful for warranty claims.
What is the difference between a PDI and a home inspection?
+
The PDI is the builder's walkthrough. An independent inspection is a third-party technical review. They serve different purposes and work best together.
When should I book a new build inspection?
+
Three milestones make sense: pre-board / pre-drywall, pre-possession (paired with the PDI), and 30–60 days before the 11-month warranty deadline.
Can an inspector help with warranty documentation?
+
Yes. The inspection report — with photos, dates, and trade categories — is exactly the kind of record warranty coordinators expect.
What if grading or exterior work is unfinished?
+
The inspector documents what's incomplete and recommends a follow-up exterior review once spring conditions allow.
Can winter limit a new build inspection?
+
Yes. Snow-covered roofs and grading, frozen ground, and AC testing below 16 °C are all winter limitations. A good report flags them clearly.
Should I inspect before possession?
+
Yes. Pre-possession inspections give you time to flag defects to the builder before keys change hands and warranty timelines start.
What if the builder says an inspection is not needed?
+
Politely proceed anyway. The inspection is your record, not the builder's. Reputable builders welcome a clean third-party review.
