2018 International Building Code - Columbia, Missouri · 2018 International Building Code • Very few consequential changes. ... provision was a response to the Station Nightclub

2018 International Building Code • Very few consequential changes. • Definitions added or amended for clarification purposes: Sleeping Unit-Single unit providing rooms or spaces for one or more persons that includes permanent provisions for sleeping and can include provisions for living, eating and either sanitation or kitchen facilities but not both. Such rooms or spaces that are also part of a dwelling unit are not sleeping units. Repair Garage-A building, structure or portion thereof used for servicing or repairing motor vehicles. (Replicated from the IFC) Greenhouse-A structure or thermally isolated area of a building that maintains a specialized sunlit environment used for and essential to the cultivation, protection or maintenance of plants.

GREENHOUSES

• In a greenhouse, the environment is such that it is maintained exclusively for, and essential to, the aggressive propagation of plants used by commercial growers for plant production. (Exempt from building thermal envelope requirements per IECC C402.1.1)

• It is acceptable for other activities to be conducted in a greenhouse, such as retail sales, educational research, conservation, education and assembly use. The occupancy class of a greenhouse will be determined accordingly.

• Greenhouses not classified as another occupancy shall be classified as Use Group U.

302.1 Classification of Occupied Roofs

• Although the City of Columbia already interpreted the code this way it has been clarified that occupied roofs are to be assigned one or more occupancy classifications in a manner consistent with the classification of uses inside the building, based upon the fire and life safety hazards posed by the rooftop activities.

• For example, where a rooftop contains a restaurant having an area/occupant load for 50 or more persons, the occupied roof would be classified as an A-2 occupancy in order to address those hazards associated with such an assembly use.

311.2 Classification of Self-Service Storage Facilities

Again, the City of Columbia already interpreted the code this way but it has been clarified that self-service storage facilities, due to the reasonable expectation it will contain a considerable amount of combustible materials, shall be classified as a Group S-1 moderate-hazard storage.

311.1.1 CLASSIFICATION OF ACCESSORY STORAGE SPACES

• Regardless of size, storage rooms and storage spaces that are accessory to other uses are to be classified as part of the occupancy to which they are accessory.

• The key point is the hazard level that storage brings to the building. It is assumed that accessory storage uses pose little additional hazard above the occupancies which they serve.

• Where storage activities pose a significantly higher hazard than the other uses in the building, they will not be considered accessory.

503.1.4 Allowable Height and Area of Occupied Roofs

• A roof level or portion thereof shall be permitted to be used as an occupied roof provided the occupancy of the roof is an occupancy permitted by Table 504.4 for the story immediately below the roof. The area of the occupied roof shall not be included in the building area as regulated by Section 506. (Any elements that enclose the occupied roof area are limited to a maximum height of 4 feet above the roof’s surface.)

Exceptions: 1. The occupancy located on an occupied rood shall not be limited to the occupancies allowed on the story immediately below the roof where the building is equipped throughout with an automatic sprinkler system and occupant notification is provided in the area of the occupied roof. 2. Assembly occupancies shall be permitted on roofs of open parking garages of Type 1 or Type 2 construction.

Table 705.2 Extent of Projections

• The minimum required clearance between the edge of a projection and the line used to determine the fire separation distance has been significantly decreased.

1004.8 Occupant Load Calculation for Business Use

• The method of calculating occupant load in business areas has been revised, which will typically result in reduced design occupant loads. However, higher design occupant loads can now be assigned to concentrated business areas such as telephone call centers and similar uses.

• The occupant load factor for business areas changes from 100 sf to 150 sf.

• For concentrated business use areas the occupant load factor changes to 50 sf.

1603.1 Construction Documents

• Construction document requirements for environmental and special loads have been updated for rain, snow and wind forces and their components.

• The roof slope factor, Cs, has been added to the required list of snow load data and factors.

• Rain load data is added to the list of design loads required on construction documents.

• Special loads, such as loads of machinery or equipment, shall be specified by their descriptions and locations.

1604.3.7 Deflection of Glass Framing • 1604.3.7 Framing supporting glass. The deflection of framing members supporting glass subjected to 0.6 times the “component and cladding” wind loads shall not exceed either of the following: • 1. 1/175 of the length of span of the framing member, for framing members

having a length not more than 13 feet 6 inches (4115 mm). • 2. 1/240 of the length of span of the framing member + 1/4 inch (6.4 mm),

for framing members having a length greater than 13 feet 6 inches (4115 mm).

• The limits do not allow a reduction to this design load for deflection analysis as was previously permitted in footnote f in the 2015 IBC Table 1604.3.

Table 1607.1 Deck Live Load

• Table 1607.1 is now consistent with the provisions in the 2010 and 2016 editions of ASCE 7 for minimum uniformly distributed live loads on decks and balconies by increasing the deck live load to one and one-half times the live load of the area served.

• Not required to exceed 100 psf.

Deck Collapse

IBC 3109 Swimming Pools, Spas and Hot Tubs

• 3109.1 The design and construction of pools shall comply with the City of Columbia 2015 “Swimming Pool Ordinance and Guide for Swimming Pool Design and Operation”. This document may be found in Chapter 11, Article VIII, Ord. No. 22439.

• 3109.2 Barrier requirements must meet the standards of the 2018 International Swimming Pool and Spa Code (ISPSC) Section 305.

• Where spas or hot tubs are equipped with a lockable safety cover complying with ASTM F1346 and swimming pools are equipped with a powered safety cover that complies with ASTM F1346, the areas where those spas, hot tubs or pools are located shall not be required to comply with Sections 305.2 through 305.7.(Barrier Requirements)

2018 International Existing Building Code Section 1106-Storm Shelters

1106.1 Addition to a Group E occupancy. Where an addition is added to an existing Group E occupancy located in an area where the shelter design wind speed for tornados is 250 mph in accordance with Figure 304.2(1)of ICC 500 and the occupant load in the addition is 50 or more, the addition shall have a storm shelter constructed in accordance with ICC 500.

2018 IEBC Section 1106 Storm Shelters Continued

1106.1.1Required occupant capacity. The required occupant capacity of the storm shelter shall include all buildings on the site, and shall be the greater of the following: 1. The total occupant load of the classrooms, vocational rooms and offices in the Group E occupancy. 2. The occupant load of any indoor assembly space that is associated with the Group E occupancy. Exceptions: 1. Where an addition is being added on an existing Group E site, and where the addition is not of sufficient size to accommodate the required occupant capacity of the storm shelter for all of the buildings on-site, the storm shelter shall at a minimum accommodate the required capacity for the addition. 2. Where approved by the code official, the required occupant capacity of the shelter shall be permitted to be reduced by the occupant capacity of any existing storm shelters on the site

2018 International Fire Code (IFC) Section 1103.5.1

Section 1103.5.1 was expanded to have a retroactive requirement requiring “Where alcoholic beverages are consumed in a Group A-2 occupancy having an occupant load of 300 or more, the fire area containing the Group A-2 occupancy shall be equipped with an automatic sprinkler system in accordance with Section 903.3.1.1. This provision was a response to the Station Nightclub fire of 2003 in Warwick, Rhode Island that killed 100 people and injured 230. The characteristics of the Station Nightclub and activities associated with the fire were discerned to be very dissimilar to the establishments/activities that would be effected by this provision in Columbia, Mo. An amendment was proposed and adopted to delete this new provision.

2018 International Fire Code (IFC) Section 3105

• In the 2015 IFC Section 3105 was introduced regulating Temporary Stage Canopies. A Temporary Stage Canopy is defined as “A temporary ground supported membrane-covered frame structure used to cover stage areas and support equipment in the production of outdoor entertainment events. The 2018 IFC expanded these regulations to govern all Temporary Event Structures which are defined as “Any temporary ground-supported structure, platform, stage, stage scaffolding or rigging, canopy, tower supporting audio or visual effects equipment or similar structures not regulated within the scope of the International Building Code.”

2018 International Fire Code (IFC) Section 3105 Continued

• The BCCC and Fire Department agreed this change to the code, in particular the associated documentation and special inspections, was over-reaching/burdensome for the needs of our community. An amendment was proposed and adopted to replace “Temporary Special Event Structure” with the 2015 language of “Temporary Stage Canopy.” The intent is to enforce these requirements for Temporary Stage Canopies only as in the 2015 IFC. Other temporary structures will be evaluated for safety per IBC standards.

2018 INTERNATIONAL RESIDENTIAL CODE

• Very few major changes. Mainly reformatting and clarification. • Many previous amendments have been removed because the

code caught up with us or the commission believed they are no longer necessary.

• Enforcement of Manual J requirements changes. • New standards for location of electric meters.

City of Columbia Code of Ordinances Sec. 27-96 – Meter Location

Meters shall normally be installed outdoors in a location approved by the department. New Standard: Meter will be mounted on the dwelling at the closest point from the transformer or secondary box (No more than 6 feet back from the corner), such that the service conduit does not cross under sidewalks, driveways or other obstructions. Meters mounted at other locations on the dwelling will be approved only if the customer furnishes and installs the conduit system per Water & Light standards and inspection. These standards will be: -3" schedule 40 PVC conduit -36" radius bends -Slip joint coupling below meter -3 feet of earth cover -Conduit to be installed from meter to 10 feet from transformer or secondary box. -Conduit must be inspected by CWL prior to backfill.

DESIGN CRITERIA & MANUAL J • Table R301.2.(1) Climatic and Geographic Design Criteria NOW INCLUDES Manual J

criteria. • The requirement for a Manual J assessment or engineered equivalent has been in the

IRC for several editions. To assist the designer, jurisdictions will now include variables for Manual J assessments with other climatic and geographic design criteria available from the building department.

• Building and Site Development (BSD) has required the Manual J to be posted at the final inspection since the 2012 IRC was adopted. We have discovered the Manual J design criteria has not been uniform and accurate.

• With the overwhelming movement toward energy compliance alternatives to the Energy Code it is imperative the Manual J design criteria match the energy compliance documents. BSD will now require the manual J to be onsite at rough-ins to verify these documents match. (Energy Compliance documents contain the inputs for accurate Manual J reports and should be shared with the HVAC contractor!)

TABLE R301.2(1)

MANUAL J DESIGN CRITERIA

Proposed Manual J Checklist

R 302.6 Dwelling-garage fire separation

• The previous amendment requiring five-eighth inch (5/8”)

gypsum board instead of one-half inch (1/2”) gypsum to separate the dwelling from the garage has been removed. Five-eighth inch (5/8”) gypsum is still required for separation from habitable rooms above the garage.

• Separation requirements from the garage are as depicted in Table R302.6 with no amendment.

R303.4 MECHANICAL VENTILATION

• The previous amendment to this section allowed “an insulated duct from the outside connected to the return air or HVAC unit ahead of the filter with a balancing damper may be provided” to meet ventilation requirements.

• This method alone is not consistent with the code or alternative energy compliance methods.

• Mechanical ventilation must be engineered or meet the alternative energy code compliance documents.

R315 CARBON MONOXIDE ALARMS

• R315 .5 Interconnectivity. Where more than one carbon monoxide alarm is required the 2018 IRC requires carbon monoxide alarm devices to be interconnected in such a manner that the actuation of one alarm will activate all of the alarms in the individual dwelling unit. • Physical interconnection is not required where listed wireless alarms are

installed and all alarms sound upon activation of one alarm. • As with smoke alarms this interconnection requirement is amended and

omitted for alterations in dwelling units no more than two (2) stories. • As with the amendment to smoke alarm requirements in alterations the

carbon monoxide alarms may be battery operated if the dwelling unit is no more than two (2) stories.

R326 SWIMMING POOLS, SPAS AND HOT TUBS

Chapter 11 Energy Efficiency

As recommended by the 2019 International Energy Conservation Code Committee it was voted to adopt Chapter 11 as written. This will eliminate previous amendments to this chapter and will also eliminate the “Residential Energy Code Requirements Diagram”. At this time the vast majority of builders here in Columbia are using performance based compliance alternatives (Columbia is well ahead of the curve on this and many other jurisdictions are following this same trend nationwide). These methods provide much more flexibility for dwelling unit components/characteristics. To follow a prescriptive path after adoption of the 2018 IRC will require third party energy code compliance documentation/plans, verification of energy code compliance as built, and third party certification.

Appendix F, Radon Control Methods

• AF103.4.2Concrete joints. (Added this code cycle) Control joints, isolation joints, construction joints, and any other joints in concrete slabs or between slabs and foundation walls shall be sealed with a caulk or sealant. Gaps and joints shall be cleared of loose material and filled with polyurethane caulk or other elastomeric sealant applied in accordance with the manufacturer’s recommendations. Because of significant concrete shrinkage and movement the committee suggested this addition to the appendix would be wasteful and proposed deletion of this requirement. This section is deleted by amendment.

APPENDIX Q TINY HOUSES

A new appendix Q covers provisions for Tiny Houses , defined as dwellings with a maximum floor area of 400 square feet. Many concessions pertaining to ceiling height, room area, lofts, loft access, and egress roof access meeting emergency escape and rescue opening standards are given to make Tiny Houses a viable option.

RESIDENTIAL 2018 IECC Changes Highlights

-Modest improvement in window U-factors for Climate Zone 4 -Do not confuse this minimum window requirement with requirement to meet energy compliance documents.

Window U-Factors R402.1.2 THERMAL ENVELOPE

• Provides allowance for duct insulation in buried duct work (for simulated energy performance analysis)

• 403.3.7-Ducts are considered inside a conditioned space if buried in ceiling insulation per 403.3.6.

Ducts Buried in Ceiling Insulation R403.3.6/403.3.7 THERMAL ENVELOPE

• Increases high efficiency lighting to 90% from 75%. • 90% of permanently installed fixtures shall contain only high

efficiency lamps. • Eliminates the low voltage exception.

High Efficiency Lighting R404.1-LIGHTING

• Increases maximum ERI score from 54 to 62 in climate zone 4. • Clarifies where on-site renewable energy is included for

compliance the building must meet the mandatory requirements of Section R406.2 and the thermal envelope shall be equal to or greater than the requirements of the 2015 IECC.

• The ANSI/RESNET/ICC 301-2014 is now a referenced standard in the code as the basis for ERI calculation. Additionally ANSI/RESNET/ICC 380-2016 is now a referenced standard for building envelope testing.

Less Stringent Target Requirements TABLE R406.4-MAXIMUM ENERGY RATING INDEX
