Purpose. The purpose of this Building Safety Code is to secure and promote the safety, health and general welfare of the people of the Northern Marianas by providing standards for the location, design, material, construction, enlargement, maintenance, use, occupancy, and moving of buildings and structures in the Commonwealth. This Code and its implementing rules and regulations are dedicated to the development of better building construction and greater safety for the citizens and residents of the Commonwealth of the Northern Mariana Islands.” –ARTICLE 1, PUBLIC LAW 6-45 Building Safety Code created and governed by the following Public Law 6-45 CNMI Administrative Code, Title 155-10.1 Adoption of International Building Code, 2009 Edition Building Safety Code Division Personnel Weston Thomas A.

A permit is required by the 2009 International Building Code as follows: “Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure to erect, install, enlarge, alter, repair, remove, convert, or replace any electrical, gas, mechanical, or plumbing system, the installation of which is regulated by this code, or to cause any such work to be done, shall first make application to the building official and obtain the required permit.” Section 105.1 In addition, the CNMI Administrative Code Title 155-10.1-040 states: “It shall be unlawful to construct, enlarge, alter, remove or demolish, or change the occupancy of a building, public or private, from one use group to another, without first filing an application with the building safety official in writing and obtaining the required permit therefore, except that ordinary repairs as defined in Section 155-10.1-005 (d) which do not involve any violation of the Safety Code…” Examples of when to obtain a permit Changing the use of a residential home to a restaurant Constructing a new building Enlarging/Extending an existing building or existing home Altering a Means of Egress system (Exit routes) Repairing structural members/Load bearing members When does the WHOLE BUILDING have to come into compliance with the CNMI Building Safety Code? There are FOUR ways that the ENTIRE/WHOLE building must comply with the codes. They are: 1. When the USE of the building or structure is changed 2. When the building or structure is INCREASED in FLOOR SPACE OR NUMBER OF STORIES 3. When ALTERATIONS OR REPAIRS are made in EXCESS OF 50% of the existing floor space area in a 12 month period 4. When ORDINARY REPAIRS EXCEED 25% of the existing floor space area in a 12 month period 1. Ordinary repairs are not to include additions, alterations, replacement or relocation of any standpipe, water supply, sewer, drainage, drain leader, gas, soil, waste, vent or similar piping, electric wiring, or other work affecting public health, safety or welfare. Many things need a permit, WHEN DO I NOT NEED A BUILDING PERMIT? The following are examples of when you do NOT need a permit: Accessory structures used as sheds, playhouses, or similar uses PROVIDED THE FLOOR AREA IS NOT GREATER THAN 120 square feet Fences not over 6 feet Retaining walls that are not over 4 feet in height measured from the bottom of the footing to the top of the wall Water tanks supported directly on grade and capacity is not greater than 5,000 gallons Painting, tiling, papering, carpeting, cabinets, counter tops, and similar finishes Swings and other playground equipment “Structures traditional to the Chamorro or Carolinian cultures, such as pala-palas, constructed primarily of natural materials indigenous to the Northern Mariana Islands…” APPLYING FOR A BUILDING PERMIT What do I need to submit? Application Package Application Memorandum of Agreement Affidavit Site Map Payment Voucher Building permit fee is calculated by a fee schedule which is dependent on the TOTAL CONSTRUCTION COST of the works to be performed Additional Requirements Zoning Permit/Clearance (From Zoning office) Business License (For Commercial Buildings/Structures) Lease Agreement (For Leased/Rented property) Approved design plans (Blueprints) BSCD Application Procedure Receive Application Package with additional requirements Applications must be complete in order to move forward Application package Received by BSCD Blueprints given to Plan Reviewer All Other documents given to Administrative staff for filing Blueprints reviewed for compliance and safety check Assuming everything is complete, in compliance, and fees are paid: Building Permit issued Document copies are made and given to owner Construction may commence Construction inspections to be scheduled accordingly with rate of construction Certificate of Occupancy given after final inspection when building or structure is completely finished What to expect when application has been turned in? One (1) BUILDING SAFETY CODE DIVISION for whole CNMI to take care of: New and renovated Single Family Homes New and renovated Multifamily Homes (Apartments, Condos, etc.) New and renovated Commercial Buildings Existing Private and Government owned buildings or structures Safety Inspections for all business in need of Annual Certificate of Occupancy Inspections of abandoned, dilapidated, unsafe buildings or structures Turn around time for application (Average): Small Projects (Minor Renovations): 1-2 weeks Medium Projects(Major Renovations/New Single Family home) : 2-3 weeks Large Projects (New Buildings) : 3-4 weeks Enormous Project (Resorts) : 5-12 weeks BETTER, STRONGER, SAFER CONSTRUCTION (MITIGATION) ReCap of Typhoon Soudelor Category 2 Storm Sustained winds of about 105 mph Gust Winds reaching about 215 mph Effects: Over 100 power poles down – several months to restore 100% of island wide power About 160 homes completely destroyed Over 1,000 homes affected ranging from minor damages to major damages Island wide green debris, road blockage Citizens and Residents Little to no food Little to no drinking water, general use water Loss of personal property, financial income Ration of fuel How did CNMI homes fare against Typhoon Soudelor? Visual Investigation of damaged homes throughout Saipan: Wood frame homes with corrugated tin: Major damage – Destroyed CMU wall homes with wood truss and Corrugated tin roofing: Minor Damage – Major Damage Reinforced Concrete homes: Affected – Minor Damage Detailed damage assessment Wood eaten by termites, inefficient or lack of bracing, fastener spacing Lack of plywood sheathing, inefficient roof panel-to-truss connection Inefficient Truss-to-wall connection, Inefficient Wall-to-floor connection Large overhangs, lack of soffits, inefficient building envelope enclosure system Understanding the wind effects on Homes Understanding Load Path Where do I start Building Better, Stronger, Safer? Roof System? Wall System? CMU (Hollow Block), Wood Frame wall, windows, doors, other openings etc. Floor Connection System? Wood Truss, Lateral Truss Bracing, Roof Sheathing, Tin Roof Panels, etc. Wall to floor connection Other things to think about Overhangs, Soffits, Ventilations, lengths, etc. Start with Building A Better ROOF Start with the ROOF Use Washered Roofing Nails with an Annular Ring Shank at least 3 inches in length Space at 6 inches on center (o.c.) throughout the perimeter of the roof Space at 12 inches on center throughout the interior field Start with the ROOF Building a better truss system Make sure at the very least to use 2 x 6 Treated Lumber 2 x 4 Lumber or smaller do not have the structural capacity for the loading conditions in the CNMI Start with the ROOF Building a better truss system Use Metal Connector plates on both sides or ½” Custom Cut Plywood rather than left over 2x2 lumber Use metal HURRICANE TIES/STRAPS to connect the roof system Ensure that installation is correct Use the correct fastener (nails or screws) and the correct number of fasteners Do not create eccentricities by adding double bottom chords Otherwise, connect bottom chords together so that it becomes one beam Space the truss systems no further than 4 feet apart from each other Space purlins no further than 24 inches apart from each other Preferrably 16 inches O.C. Place a lateral brace on either end of the roof system to aide with lateral forces Next, Build Better WALLS For Wood Frame Walls Space wall studs no further than 24 inches on center Preferrably 16 inches On Center (o.c.) Place double top plates rather than single top plates Install ‘NOGGINS’ or ‘FIREBLOCKING’ in between all wall studs Fasten perimeter of ½” or 5/8” plywood, gypsum board, or cement board at 6 inches o.c. Next, Build Better WALLS For Concrete Masonry Walls Space vertical reinforcements (rebar) no more than 24 inches on center Grout all cells with reinforcements At a minimum, grout every other CMU cell Ensure that ALL CMU cells within 24 inches of the corners of masonry walls are grouted Ensure that horizontal reinforcements are placed a minimum of every 3 layers Ensure that vertical reinforcements are doweled into the new foundation slab A minimum of 4 inches into an existing foundation slab Also, create better FLOOR CONNECTIONS Ensure that the walls are securely fastened to the floor/ foundation slab Install “J Bolts” of at least 1/2 inch at a maximum of 6 feet on center “J Bolts” must be securely fastened within the concrete slab or wall footing Use HURRICANE TIES/STRAPS to secure walls to floor How else can I Build Better, Stronger, Safer? Make sure to follow the Manufacturer Installation guides Do not retrofit or alter installation If possible, purchase TYPHOON SHUTTERS in order to protect openings such as windows and doors Shorten the span of the overhang 6 – 12 inches is ideal Ensure that the underside of the overhang (soffit) is enclosed with the proper fire rated material Request the help and advice of the Building Safety Code Division even when it is not required INFORMATION FOR THE FUTURE Typhoon Shelter plans (Professionally engineered) available for the charge of copies (less than $20) at BSC office Currently 2 available house plans (Basic Designs-load compliant) available for the charge of copies at BSC office Planning for 6 more house plans to be made available with 2-3-4 bedrooms, professionally engineered Working with hardware stores to bring in new material, technology, and required construction hardware Outreach to community on better, stronger, safer will commence in the near future Outreach to all villages on different days for the purpose of educating homebuilders on better building practices Be sure to inform Building Safety Code Division of any works to be performed prior to commencing work Building Safety Code Division 2ND FLOOR JOETEN OLEAI COMMERCIAL BUILDING OFFICE HOURS: 7:30AM – 4:30PM, MON – FRI Tel.
