For various reasons, a structure may not be eligible for this program. These include:
- Structural Deficiencies: If a site inspection reveals that the building is not structurally capable of supporting or justifying the sound insulation improvements, the building will be made temporarily ineligible until the owner corrects the deficiencies.
- Building or Zoning Violations: Outstanding Building and Zoning Code violations may render a structure temporarily ineligible until all required permits have been obtained and clearance from the Building and Safety Division has been given.
- Outside Program Boundary: The program boundary is defined by the 2020 Noise Exposure Map (NEM) contour line, as shown on the map produced by Federal Aviation Administration (FAA). Properties outside this boundary are not eligible for this program.
- New Construction, and All Housing Built After 1998: Considered to be land-use compatible. Therefore, these properties are not currently eligible for sound insulation grant funds.
- Currently Meets Interior Noise Standards: Any property for which conformance to the current standards (interior level of 45 dB CNEL) is shown to exist will not be eligible for this program. Interior noise level will be determined by the acoustical noise testing.
