Key Elements in the Pomona Building Code for STC
The main things established by the Pomona building code for STC are;
Minimum Requirements for STC by Pomona Building Code The Pomona Building Code will detail the minimum STC value required in walls, floors, and ceilings in various regions of the building. A commercial or apartment unit’s interior partitioned wall must have at least an STC of 50 to ensure acoustic separation.
- Construction Materials: The code provides for materials such as soundproof drywall, insulation, and acoustic sealants to achieve the required STC rating. All these materials minimize sound transmission in walls, floors, and ceilings.
- Specific Applications: The code has various STC ratings depending on the intended use of the building. For example, in apartment buildings, the STC rating for walls between apartments should be higher than that of partitions within an apartment.
- Soundproofing Design Considerations: The Pomona code offers the following considerations for designing soundproofed spaces. These include decoupling, mass-loaded vinyl, and acoustic panels for enhanced sound insulation.
Why is STC Important in Building Codes?
Ensure Privacy and Comfort
An STC rating in the Pomona Building Code primarily aims at satisfying privacy and comfort within a given building. Poor sound insulations result in noise disturbance and dissatisfies the occupants. For instance, without correct soundproofing, the persons residing in an apartment structure would be able to hear every type of noise from footsteps through conversations, which results in poor privacy.
Legal Health Standards Compliance
Apart from comfort enhancement, compliance with the Pomona Building Code for STC ensures that buildings comply with local noise regulations. Excessive noise may cause stress, sleep deprivation, and even hearing impairment; hence, buildings must meet these standards.
Noise Reduction
The Pomona Building Code is concerned with the reduction of noise pollution from both inside buildings and from external sources. Through specific STC ratings, buildings can play a role in quieter neighbourhoods and communities that promote quality of life among their inhabitants.
How to Attain the Desired STC Rating in Pomona
Selecting the Correct Materials
For construction professionals to meet the Pomona Building Code for STC, they have to use the right materials. Materials that can increase sound insulation include the following:
- Acoustic Insulation: These are specialized insulation materials that can be used to fill cavities in walls and ceilings. They help in absorbing sound and reduce its transmission.
- Double-Stud Walls: It is possible to create separate layers of studs in building walls that help to isolate sound, thereby increasing the overall STC rating.
- Mass-Loaded Vinyl (MLV): This is a heavy material that is often added to walls or ceilings to block sound effectively.
- Acoustic Sealants: Sealing gaps around doors, windows, and joints with acoustic caulk prevents sound from passing through those openings.
Design Considerations for Soundproofing
In addition to the materials, the Pomona building code for STC encourages the adoption of construction techniques that can enhance soundproofing. A few of these include:
Decoupling refers to the separation of two surfaces, such as the wall and the ceiling, through which sound cannot travel throughout the structure.
Floating Floors
The installation of a floating floor on a layer of soundproofing material could reduce sound transmission between floors.
- Adding mass to walls and ceilings: The STC rating of walls and ceilings can be significantly improved by using soundproof drywall or heavy-duty plywood.
What Are the STC Requirements for Different Types of Buildings?
Residential Buildings
Specifically focused on preventing noise between living spaces is the Pomona Building Code for STC in apartments or townhouses. It says that walls between apartments are set to meet at least an STC rating of 50, while floors and ceilings between units, likewise, are set to an STC rating of 55.
Commercial Buildings
For commercial spaces, the Pomona Building Code may require different standards depending on the building’s use. Offices or retail spaces typically have less stringent STC requirements compared to residential units. However, spaces such as meeting rooms or sound-sensitive areas, such as theatres, may have higher requirements.
Mixed-Use Buildings
In mixed-use buildings where both residential and commercial spaces exist, the Pomona Building Code for STC imposes stronger sound insulation between residential and commercial units. In this category of buildings, some of the walls separating residential units from commercial or retail areas require an STC rating of 55 or greater. Other interior walls inside these units must have an STC of 50 or more.
Errors to Avoid in Meeting the Requirements for STC
Failure to Account for All Noise Sources
One common mistake is only addressing noise between rooms but ignoring sound coming through windows or doors. The Pomona Building Code for STC requires a holistic approach to soundproofing, where all surfaces contribute to sound isolation.
Using Insufficient Materials
Another common error is using materials that do not meet the minimum STC standards. Drywall, for instance, cannot be used on walls with higher STC requirements as it will not achieve sufficient sound insulation.
Failure to Address Flanking Paths
Flanking noise can pass through a wall if it has been inadequately sealed. It is important to account for all possible flanking paths including gaps around windows, door frames, or openings in ventilation.
Comparison of STC Ratings in Different Areas

How STC Rating Impacts Property Value
STC rating in buildings impacts not only the noise level but also impacts the value of the property. In places where noise pollution is high, or privacy is more valued, properties that have an STC rating or better are preferred. This is particularly true in multi-family buildings where the noise between units can impact tenant satisfaction and the overall attractiveness of the property.
Effect on the Value of Residential Property
- Increased Potential Rent: Properties with higher STC ratings (better sound insulation) tend to command higher rents because of increased privacy and comfort.
- Longer Tenancy: Tenants are more likely to stay longer in a building with superior soundproofing, resulting in lower turnover rates and reduced vacancy periods.
Effect on Commercial Property Value
Enhanced workplace comfort; higher productivity; better use in buildings
- A high STC rating inside may allow for a better atmosphere, comfort, and employee performance in commercial buildings and result in higher office space worthiness.
- Attract the Noise-Sensitive Businesses
- Only specific businesses like law firms, design companies, and music studios may be looking to occupy a space for some quiet environment.
Pomona Building Code for STC: Comparison with Other Areas
STC Ratings in California
Pomona’s building code for STC is generally consistent with California’s general building regulations. California, as part of the California Building Standards Code, requires specific STC ratings for different types of buildings. However, local jurisdictions such as Pomona may add more requirements based on the needs of the community.
For example:
California Building Code (CBC) mandates that residential units have STC ratings of 50 for walls and 55 for floors between units. This complies with the city of Pomona’s requirements for multi-family residential buildings.
In non-residential or mixed-use buildings, though the requirement is more relaxed, the emphasis is on sound isolation between spaces. For example, between commercial and residential areas.
Pomona vs. Los Angeles
In contrast to Pomona, other cities around Los Angeles have more stringent requirements for STC ratings for mixed-use buildings. In some zones, STC ratings go as high as 60 or higher for the walls dividing residential and commercial spaces. This is more so on projects near transportation hubs, as noise pollution can be particularly high.
National Building Code Standards
On a national level, the International Building Code (IBC) gives general guidelines for STC ratings but allows for local jurisdictions to enforce more stringent standards based on environmental factors. Pomona is an urban area and follows the IBC but adds local stipulations based on noise levels, density, and building type.
