How much would it cost to soundproof a yoga studio above a residential unit in an Ottawa mixed-use building?

Soundproofing a yoga studio above a residential unit in an Ottawa mixed-use building typically costs $20,000–$50,000 depending on the studio size, the existing floor-ceiling assembly, and the specific activities involved. This is one of the more challenging commercial soundproofing scenarios because yoga studios generate both airborne noise (music, instructor voice amplification, group chanting) and impact noise (footfall during vinyasa flows, mat drops, and especially high-impact activities like hot yoga jump-throughs). The Ontario Building Code requires a minimum STC 50 and IIC 50 between commercial and residential spaces, but for a yoga studio you should target STC 55–60 and IIC 60–65 to avoid ongoing complaints from the tenant below.The floor is the single most important element and will consume roughly 50–60 percent of your total budget. A professional floating floor system involves installing a resilient underlayment — products like Pliteq GenieMat RST, Regupol, or equivalent — over the existing subfloor, followed by a new plywood subfloor layer that sits entirely on the resilient mat without any rigid connection to the walls or structure. This costs $8–$18 per square foot installed, or $8,000–$18,000 for a typical 1,000-square-foot studio. On top of the floating floor, you will want a thick commercial rubber yoga flooring ($4–$8 per square foot) which adds both impact absorption and mass. The combination of floating floor plus rubber surface can achieve IIC 60–70, which is the range where impact noise from above becomes barely perceptible in the unit below.Walls, Ceiling, and Mechanical SystemsAirborne sound — particularly amplified music and bass from a sound system — requires attention to the walls and ceiling as well. If the studio has a dedicated sound system (most do), the bass frequencies will find every structural connection and flanking path. Adding sound isolation clips with hat channel and double 5/8-inch Type X drywall with Green Glue to the walls costs $15–$25 per square foot installed and brings wall performance to STC 55–62. If the existing ceiling is exposed structure or a basic drywall finish, a decoupled ceiling assembly with isolation clips adds $12–$20 per square foot, or $12,000–$20,000 for the full studio ceiling — expensive but often necessary for music-heavy classes.Do not overlook the HVAC system. Yoga studios require significant ventilation — especially hot yoga studios — and ductwork shared with the residential unit below is a direct sound pathway. Acoustic duct silencers cost $300–$800 each and you may need 3–6 depending on the layout. All duct penetrations through the sound-rated floor must be isolated with resilient connections and sealed with fire-rated acoustic sealant. Budget $2,000–$5,000 for mechanical noise control. You will also need vibration isolation pads under any rooftop or in-unit HVAC equipment to prevent mechanical vibration from transmitting through the structure.A building permit is required for this scope of work in Ottawa since you are modifying fire-rated assemblies and commercial spaces — apply through 3-1-1 or ottawa.ca. Your landlord or condo corporation will also need to approve the work, and they may require an acoustic engineer's report both before and after construction to confirm code compliance. For a project of this complexity and cost, starting with a professional noise assessment ($800–$1,500) is essential to identify exactly where the noise is transmitting and target your budget effectively.
