In a Vancouver condo the floor you like is rarely the deciding factor. The strata bylaws are. Nearly every building in Metro Vancouver sets a minimum impact sound rating for hard flooring, and installing without approval can mean tearing the floor out at your own cost. This guide explains the ratings, the four floor types that usually pass, and the paperwork that gets an approval through in one round.
1. IIC and STC, in plain language
- IIC (Impact Insulation Class): how much footstep and dropped-object noise reaches the unit below. This is the number in most strata bylaws.
- STC (Sound Transmission Class): how much airborne sound, such as voices and TV, passes through. Less commonly specified for flooring.
- The rating belongs to the assembly: concrete slab, underlay, floor and the ceiling below are all part of the tested number. A product alone does not have a building rating, which is why boards ask for the test report.
- Typical requirements: IIC 50 is the common minimum in Metro Vancouver; newer towers often specify 55 to 65.
2. The four floors that usually pass
| Floor | Why it works in a condo | Material / sq ft |
|---|---|---|
| Engineered hardwood | Real wood over a stable core; floats or glues over concrete; best resale value | $3.49–$13.99 |
| SPC vinyl plank | Waterproof, most planks include an IXPE pad that meets a basic bylaw | $2.59–$6.05 |
| Cork | The best sound absorber of the four, warm underfoot | $1.09–$1.69 |
| Laminate | Lowest cost; choose planks with attached underlay to hit the rating | $1.69–$3 |
Rain-tracked-in moisture at the entry is the other Vancouver factor. If your unit opens onto a patio or you have pets, waterproof vinyl plank is the lower-risk choice; hardwood is the better long-term value in a dry unit.
3. Choosing the underlay
- Attached pad: many SPC and laminate planks come with IXPE or cork bonded on. Do not add a second layer unless the manufacturer allows it, because the floor can flex and the locks can fail.
- Separate acoustic underlay: needed for most engineered hardwood floating installs, and any time the board wants a higher number. Quiet Walk Plus reaches IIC 71 in its tested assembly.
- Glue-down hardwood: ask about an acoustic membrane or an adhesive with sound-reduction data, since there is no underlay layer.
- Moisture: over a concrete slab, use an underlay with a vapour barrier or lay 6 mil poly first.
4. Strata approval checklist
- Request your building's flooring bylaw in writing, including the required IIC number.
- Choose the floor, then request the acoustic test report for the assembly from us.
- Submit the spec sheet, the test report, your installer's certificate of insurance and the planned work dates.
- Book the elevator and loading bay once approval comes through; most buildings restrict move-in hours.
- Keep the approval email: it protects you if a neighbour complains later.
- Allow two to four weeks for the approval process before your install date.

Frequently asked questions
What IIC rating does my strata require?
Most Metro Vancouver buildings require IIC 50 or higher, and many newer towers ask for 55 to 65. The number is in your bylaws; ask the property manager for it in writing.
What is the difference between IIC and STC?
IIC covers impact noise such as footsteps; STC covers airborne noise such as voices. Flooring bylaws usually specify IIC.
Can I install hardwood in a condo?
Usually yes, with an approved acoustic underlay. Some older buildings restrict hard surfaces, so check before you buy.
Does vinyl with an attached pad need underlay?
Normally no, and adding one can void the warranty. If you need a higher rating, ask which underlay the manufacturer approves.
How long does strata approval take?
Two to four weeks is typical. Councils often meet monthly, so submit early.
