Rainy days limit your space

More square footage means considering Burnaby’s rainy months. The new space must keep the weather out while connecting to the yard. If damp boots and wet jackets pile up, the addition can feel more like a hallway than a room.

A home addition here can also enhance your outdoor living. A main-floor bump-out next to the kitchen can turn a cramped dining nook into a bright eating area that opens onto the back deck.

Expand Your Living Space

Adding onto your home lets you stay in the neighborhood you love while gaining the space your family needs. Instead of losing your Burnaby yard, a well-planned addition connects to your existing exterior for a unified look and more usable space. Home additions in Vancouver begin with a solid structure that keeps the inside dry, no matter the weather outside.

We frame the addition with strong materials and cover it in siding that matches your house, whether that’s HardiePlank, cedar, or a fresh coat of paint. Installing windows and doors seamlessly ensures the whole exterior works as one weathertight system, so you won’t have to deal with drafts or moisture later.

Why It Matters in Burnaby

Burnaby’s mid-century bungalows and split-level homes sit on lots that give you space to expand without crowding the yard. When the original exterior needs updates, an addition is a great time to bring everything together. That’s why many Burnaby homeowners choose us to manage the entire exterior project.

The region’s heavy rains require proper siding overlap, overhangs, and high-quality caulking. We connect the new addition to the old without moisture problems and match trim and paint for a smooth appearance. Every material is built to withstand coastal freeze-thaw cycles.

Weathertight Assembly Techniques

Framing for a home addition in Burnaby starts with pressure-treated plates and engineered rim joists. These materials help resist moisture from the ground. We align new wall planes with the existing house so the siding fits well, avoiding ledges where water could collect. We tape all joints in the sheathing to create a strong air and water barrier before putting on the cladding.

For siding installation, we follow rainscreen principles. Vertical strapping over the water-resistive barrier creates a drainage gap behind fiber cement or cedar lap siding. We use sloped sill pans for window and door openings, along with flexible flashing at the jambs. A backer rod with high-grade sealant helps manage Burnaby’s heavy seasonal rains.

Engineering Drainage Planes

Keeping the building envelope continuous between the old and new structure is important in Burnaby’s damp climate. We overlap the new water-resistive barrier with the existing weather barrier at the tie-in, shingle-fashion, so moisture drains outward. Flashing at the base of the addition directs water away from the foundation, which helps prevent moisture from rising into the wall assembly.

The wall assembly is designed to dry to the outside. A ventilated rainscreen gap behind the cladding allows any incidental moisture to escape. The vapor-permeable housewrap lets the sheathing dry inward if needed. We adjust the fastening patterns for siding and trim based on local wind exposure, using closer spacing at corners and edges to keep the sealant effective during coastal storms.

Burnaby Permit Requirements for Additions

For a home in Burnaby, any change to the building’s footprint or increase in floor area is classified as a home addition and requires a building permit. This includes expansions to existing accessory structures such as garages, decks, and patio covers. Permit applications for alterations and additions must be submitted online through the City’s My Permits Portal. A printed copy of the approved permit package and drawings must be kept on site for inspections.

For residential home additions, the City requires the use of its building permit process. Additions must be applied for as an Addition or Floor Addition scope of work. Adding a new secondary suite requires a new building permit, which cannot simply be added as a revision to an existing permit. Separate permits are required for trades such as electrical, plumbing, and gas when they are part of the home addition work.

Burnaby’s Zoning Bylaw No. 14815 sets zoning districts, yard setbacks, height limits, and lot coverage rules that home additions must follow. Any addition that increases floor area or changes the building footprint must fit within the applicable setbacks and regulations for its zoning district. Additions that create new dwelling units or significantly increase density may require rezoning or development permit approvals before a building permit can be issued.
