We want to add in-floor radiant heating to our basement in a Port Moody townhouse strata — is $8,000 to $12,000 a fair estimate, and will the strata likely require an engineer's report before approving it?

For a Port Moody townhouse strata, $8,000–$12,000 is a reasonable mid-range estimate for in-floor radiant heating in a basement, though the final number depends heavily on whether your slab can be cored for hydronic tubing or whether you're going electric — and yes, your strata will almost certainly want documentation before approving the work.

Electric vs. Hydronic — The Decision That Drives Everything

The two systems have very different cost profiles and strata implications. Electric radiant (mat or cable systems) is the more common choice in Metro Vancouver strata basements because it doesn't require a boiler, manifold, or connection to the home's heating system. A typical 800–1,000 sq ft basement electric radiant installation runs $6,000–$11,000 installed, including the thermostat, electrical panel upgrade if needed, and labour. It sits within your $8,000–$12,000 range comfortably for a mid-sized basement.

Hydronic radiant (hot water tubing) is more efficient long-term but significantly more complex in a strata townhouse. It requires a boiler or connection to an existing hot water system, a manifold, and PEX tubing either embedded in a thin concrete topping slab or run through a sleeper system above the existing slab. In a strata context, the boiler and any shared mechanical connections immediately trigger strata scrutiny. A hydronic system in a townhouse basement typically starts at $15,000–$25,000 once you factor in the boiler and installation — well above your estimate range. If your contractor quoted $8,000–$12,000 for hydronic, clarify exactly what's included.

The Strata Approval Question

Port Moody strata corporations are governed by BC's Strata Property Act, and any alteration to a strata lot that affects the structure, common property, or shared systems requires written strata council approval — often a bylaw-defined process requiring a formal alteration agreement. In-floor radiant heating almost always triggers this because it involves modifications to the concrete slab (even for electric systems, penetrations for conduit are involved), changes to the electrical system, and potentially affects the unit below or adjacent units if there are any shared assemblies.

Whether an engineer's report is required depends on your strata's specific bylaws, but for anything involving the slab — coring, cutting, or adding a topping layer — most Port Moody stratas will request one. If you're in a newer townhouse development (post-2000, common in Port Moody's Inlet Centre or Heritage Mountain areas), the slab may be post-tensioned concrete, which absolutely cannot be cored or cut without a structural engineer's assessment. Cutting a post-tensioned tendon is a catastrophic structural failure risk. Your contractor must confirm the slab type before any work begins — this is non-negotiable.

Practical Steps Before You Commit

Start by pulling your strata's bylaws and submitting a written alteration request describing the system type, scope of work, and contractor credentials. Ask your strata manager directly whether an engineer's letter is required — many will tell you upfront. Budget $1,500–$3,500 for a structural engineer's review if the strata requires it, and factor that into your overall project cost.

For the heating system itself, make sure your contractor pulls the required electrical permit through the City of Port Moody and that the work is inspected by Technical Safety BC. This protects you with the strata and with your home insurer. Any contractor doing the electrical component must be a licensed electrical contractor — this isn't a grey area in BC.

One Metro Vancouver-specific note: Port Moody's basement moisture conditions vary considerably between hillside properties near Burrard Inlet and flatter areas near Ioco Road. Before installing any radiant system, confirm your basement slab is dry and that there's no active moisture infiltration — radiant heat won't cause moisture problems, but finishing over an existing moisture issue always will.
