Here is a practical, step-by-step checklist for residents who suspect their apartment units do not meet soundproofing (STC) standards and want to take action.
Resident Soundproofing Complaint Checklist (STC Non-Compliance)
1. Identify and Document the Problem
Describe the issue: Is it airborne noise (talking, TV), impact noise (footsteps, furniture), or both?
Record when it occurs: Time of day, frequency, duration.
Keep a log: Document specific disturbances over 2-4 weeks.
Record audio/video if possible (without violating privacy).
Talk to neighbors: Are others experiencing the same issues?
2. Review Lease or Sales Agreement
Check for any language about quiet enjoyment, construction standards, or soundproofing claims.
If STC/IIC values or compliance with building codes or advertised features are mentioned, note these down.
3. Research Building Standards
Look up your local building code (e.g. IBC in U.S., Part E in UK, SANS 10400 in South Africa).
Verify the required STC/IIC ratings for walls and floors in multi-family buildings.
Compare with what the builder/developer advertised or was required to build.
4. Request Testing or Proof of Compliance
Submit a written request to the building manager, developer, or homeowners association:
Ask for sound insulation test results (STC/IIC).
Request a copy of the Certificate of Occupancy and any acoustic compliance documentation.
If the developer refuses or delays, move to the next step.
5. Get a Professional Sound Test (Optional)
Hire an acoustical consultant or building inspector to perform:
Field STC/IIC testing of your unit.
Report on any deficiencies or non-compliance.
Request a formal, written report (may help in legal or insurance processes).
6. File a Formal Complaint
To HOA or body corporate:
If you're an owner, file a motion for review or mediation.
To Consumer Protection Agencies:
File with state/provincial or national consumer agencies.
To the Building Authority:
Contact your local municipal building department or code enforcement office.
Provide logs, videos, sound test results, and lease/sale documents.
7. Explore Legal Action (If Needed)
Consult a tenant rights attorney, construction lawyer, or ombudsman.
Possible legal claims include:
Breach of quiet enjoyment
Misrepresentation or false advertising
Breach of building regulations
Latent construction defects
Consider collective action with other residents for stronger impact.
8. Remediation or Compensation
Ask the developer/HOA for:
Remedial works (e.g. soundproofing upgrades)
Rent reduction or financial compensation
Early termination of lease without penalty
Remember to keep all correspondence in writing.
Helpful Tip:
Always remain calm, factual, and documented. Developers and landlords often take concerns more seriously when residents show they have done their homework.
