Can I add an ensuite to my master bedroom in a split-entry home in Riverview?

Yes, you can typically add an ensuite to your master bedroom in a split-entry home in Riverview, but you'll need to navigate both structural considerations and municipal permits since this involves plumbing rough-in work.

Split-entry homes in Riverview (very common from the 1970s-1990s) actually offer some advantages for ensuite additions. The upper level where your master bedroom is located usually has adequate floor joist depth to accommodate new drain lines, and you're likely close to the existing plumbing stack. The key challenge is often finding space within the bedroom itself and ensuring proper drainage slope to connect to your main waste line.

Structural and plumbing requirements are significant here. You'll need to verify that your floor joists can handle the additional load of fixtures, tile, and water. Most split-entries have 2x10 or 2x12 joists on 16" centers, which typically work fine, but an engineer should confirm if you're adding a heavy soaker tub. The new plumbing will need to tie into your existing waste stack, and you'll need adequate fall (minimum 1% grade) for the drain lines - this sometimes means lowering the ceiling below or raising the floor slightly.

For permits in Riverview, you'll need to contact the Town of Riverview Development Services since this involves both building and plumbing permits. The building permit covers the structural modifications, electrical work for new outlets and ventilation, and ensures the addition meets National Building Code 2020 requirements (effective May 1, 2025 for new applications). The plumbing work must be done by a licensed plumber (licence issued by NB Dept. of Justice and Public Safety - Technical Inspection Services), and you'll need a plumbing permit from TIS at 1-888-659-3222.

Ventilation is critical in New Brunswick's climate - you'll need a proper exhaust fan vented to the exterior (not into the attic) to handle moisture. Many split-entries have moisture issues already due to our clay soils and freeze-thaw cycles, so proper vapor barriers and ventilation are essential.

Budget-wise, expect $25,000-$45,000 for a basic ensuite addition in your split-entry, or $45,000-$75,000 for a luxury renovation with high-end fixtures. This includes the plumbing rough-in ($3,000-$5,000), electrical work ($1,500-$2,500), flooring, tiling, fixtures, and permits. Costs can increase if you need structural modifications or if access to existing plumbing is challenging.

Start by measuring your master bedroom to see where an ensuite could realistically fit - even a 5'x8' space can accommodate a three-piece bathroom. Then contact a licensed plumber to assess your existing plumbing configuration and determine the best connection point to your main stack.
