Study Notes
Occupancy Classification
- Determining occupancy classification is a crucial first step in researching building codes.
- If a building has two occupancy types, the larger one is deemed the main occupancy while the smaller is classified as accessory.
- Subcategories of occupancy classifications influence more than just occupancy load; they affect various safety requirements.
- Locations of fire-resistance-rated walls are pivotal in buildings with multiple occupancy classifications.
Mixed Occupancy
- Two different occupancies separated by a non-rated wall can be categorized as separated mixed occupancy.
- The number of occupants receiving care in assisted living determines if it’s classified as institutional or residential occupancy.
Childcare and Educational Classifications
- The classification of a preschool as institutional or educational does not depend solely on the number of children receiving care.
- Space size does not determine if an indoor pool is classified as A-3 or A-4 occupancy.
Occupancy Classifications for Specific Uses
- Key occupancy classifications for restaurant design under the International Building Code and Life Safety Code include Assembly, Business, and Mercantile.
- The Life Safety Code categorizes institutional occupancies as Detentional/Correstional, Healthcare, Daycare, or Residential Board and Care.
Risk Factors and Measurement
- Various hazardous situations in buildings are referred to as risk factors.
- Gross square footage is used when measuring building area, encompassing all miscellaneous spaces.
Hazardous Occupancies
- Codes classify hazardous occupancies into four main categories: Fire, Explosive, Physical, Health.
- Determining occupancy classification involves assessing the type of activity, potential hazards, and occupant numbers.
Life Safety Code and Occupancies
- The Life Safety Code differentiates between new and existing occupancies, with certain scenarios not creating a new occupancy.
- Residential and Institutional occupancies can have different subclassifications based on occupant counts.
Education and Residential Occupancies
- Some building types, like nursing homes, may not always be regarded as residential occupancy.
- Restaurants are less likely to be classified as mixed occupancy compared to other types.
Americans with Disabilities Act Regulations
- Certain occupancy classifications, like factories, are less regulated under the Americans with Disabilities Act compared to others.
Accessory Occupancies and Mixed Occupancy Compliance
- Accessory occupancies must not exceed 10% of the primary occupancy’s area, though this condition might not always be true depending on guidelines.
- In mixed occupancy buildings, compliance with the most stringent classification is required for non-separated mixed occupancies.
Occupant Load Calculation
- To increase a space’s occupant load beyond calculated limits, additional exiting and prior approval from a code official are necessary.
- The occupant load is not relevant when determining construction type but is required for defining occupancy loads based on load factor and square footage.
Space Use and Occupant Loads
- For spaces with multiple uses, the occupant load is determined by the use indicating the highest concentration of people.
- Determination of fixed seating includes criteria such as immovability, continuity, and permanence.
Live/Work Units
- Live/work units are defined as such if the residential portion is less than the nonresidential, with their total area regulated by codes.
