Every spring in Regina, the same thing happens: homeowners who spent the winter thinking about a deck start making phone calls in April and find out that the good contractors are already booked into July. Deck season in Saskatchewan is short and the demand is real. If you want a deck built this year, the planning has to happen before the snow is fully gone — not after.

Here is what to understand before you talk to a contractor or pull a permit.

When Does a Deck Require a Permit in Regina?

The short answer: most decks require a permit. The City of Regina generally requires a building permit for any deck that:

  • Is attached to the house (ledger-mounted)
  • Is more than 600 mm (about 24 inches) above finished grade at any point
  • Has any structural element — posts, beams, or footings — regardless of height

A small ground-level platform patio with no attachment to the house and no structural posts may not require a permit, but anything beyond that almost certainly does. When in doubt, call the City of Regina Building Standards office before you start — not after. Unpermitted decks come up during home sales and can be a significant problem.

For a permitted deck you will typically need to submit a site plan showing the deck location relative to property lines, a structural drawing or sketch showing footing depth and beam/joist sizing, and confirmation that setback requirements are met (typically 0.6 metres from side lot lines for accessory structures in Regina, but verify this for your specific zone).

Frost Line and Post Depth — This Is Not Optional

Saskatchewan frost depth in the Regina area is approximately 1.8 to 2.1 metres. This is the depth below which the ground does not freeze in a typical winter. Every deck post footing needs to sit below this line — if it does not, the footing will heave with freeze-thaw cycles, and your deck will rack, lift, and eventually become structurally unsafe.

This is one of the most common corners cut on low-bid deck builds. A footing at 1.2 metres might look fine for a season or two, but it will move. The repair cost — releveling posts, replacing damaged framing — almost always exceeds what was saved on the original build.

Concrete tube forms (Sonotubes) poured to a minimum of 1.8 metres below grade, with a bell-bottom flare at the base, are standard practice in this region. Make sure any contractor you hire can confirm exactly how they handle footings and what depth they are installing to.

Material Choices for Saskatchewan Climate

Saskatchewan climate is brutal on outdoor materials. You get UV exposure, extreme temperature swings (from minus 40 in winter to plus 35 in summer), moisture from spring snowmelt, and freeze-thaw cycling. Material choice matters more here than it does in a moderate climate.

Pressure-treated pine is the most common decking material in Regina and for good reason. It handles the climate well, it is cost-effective, and it is widely available. The current generation of pressure-treated lumber (ACQ or MCA treated) is more corrosion-aggressive than older formulations, so you need stainless steel or hot-dipped galvanized hardware throughout — standard fasteners will corrode and stain the wood. PT pine requires sealing or staining every two to three years to look its best.

Cedar is a premium natural option that handles moisture and UV better than pine, and it looks excellent. It is softer than PT pine, which means it dents more easily. Cost is roughly 50 to 80 percent more than pressure-treated for the decking boards themselves. It still requires a UV-protective finish to prevent graying.

Composite decking (Trex, TimberTech, and similar brands) has become increasingly popular and the quality gap between composite and wood has closed significantly. In Saskatchewan climate, quality composite outperforms wood on longevity — it does not rot, does not require annual sealing, and holds colour well. The upfront cost is higher (typically $12 to $22 per linear foot for decking boards versus $3 to $7 for PT pine), but the reduced maintenance cost over a 10 to 15 year lifespan often makes it competitive on a total-cost basis.

One caveat on composite in Saskatchewan: expansion and contraction across our temperature range is significant. Composite decking must be installed with the manufacturer-specified gap and fastener pattern for your climate zone. Improper installation leads to buckling in summer heat.

What Actually Drives Deck Cost Up

For a basic 12-by-16-foot attached PT pine deck in Regina, expect a contractor-built cost in the $12,000 to $20,000 range including permit, footings, framing, decking, and a simple railing. That range moves based on:

  • Railing type. Cable railing or glass panel railing can add $3,000 to $8,000 over a basic wood or aluminum railing.
  • Stairs. A large landing stair system with multiple runs adds significant labour and material cost.
  • Material upgrade. Switching from PT pine to composite on a mid-size deck adds $2,000 to $5,000 to materials alone.
  • Size and shape. An L-shaped or multi-level deck has more cuts, more posts, more labour.
  • Site conditions. A deck built over a significant slope requires more post height and sometimes engineered footings. This can add $2,000 or more.

Best Time to Build in Saskatchewan

The ground needs to be thawed and workable for footing installation — in Regina that usually means mid-April at the earliest in a normal year, and sometimes into early May. Concrete should not be poured when temperatures are forecast to drop below zero in the first 24 hours after placement.

The practical build window is May through September. The best time to book a contractor is February or March for a May or June start. By the time the snow is gone and you are walking around thinking about a deck, the quality contractors have already filled their spring schedules.

What to Ask a Deck Contractor Before Hiring

  • What footing depth do you install to, and do you have a soil bearing capacity assessment process for unusual sites?
  • Are you pulling the permit and handling inspection scheduling?
  • What hardware do you use with pressure-treated lumber — is it rated for ACQ-treated wood?
  • Can I see examples of decks you have built in the last two seasons?
  • What is your warranty on structural work?

A good contractor will answer all of these without hesitation. Anyone who gets defensive about the permit question is not someone you want building a structure attached to your house.
