a model building code is a building code that is developed and maintained by a standards organization independent of the jurisdiction responsible for enacting the building code. a local government can choose to adopt a model building code as their own. this saves local governments the expense and trouble of developing their own codes. many smaller governments lack the expertise to do so. ==overview== the concept of the model building codes has successfully been applied since the early 1900s in the countries where regulation of building construction is a responsibility of the local authorities. the popularity of model building codes can be attributed to two factors: (a) the developing of proprietary building codes is prohibitively expensive and (b) the ability of the model codes to accommodate local conditions. since modern building regulations are very complex, their development and effective maintenance are far beyond the technical and financial capabilities of most jurisdictions. rather than drafting its own building codes, a local authority might choose to use the model building codes instead. the model building codes are either adopted (accepted without modifications) or adapted (modified) to a particular jurisdiction and then enforced by the adopting authority. model building codes are developed by standards organizations through a network of development committees with representatives from the various affected entities, both government and private. this method allows the pooling of financial and intellectual resources to produce codes that remain current and technically sound. the model code developers are constantly working to update their codes to incorporate latest research results and building technologies. the model code developers are generally funded by the sales of the model codes, the reprint royalties, and the consulting services they may offer to the adopting authorities and code users. ==application== ===european union===  ===canada===  ===united states=== in the united states, model codes are adopted by the state governments, counties, fire districts, and municipalities. a number of federal agenciesâincluding the u.s. department of defense, the national park service, the department of state and the forest serviceâuse private-sector model codes for projects funded by the federal government. normally, model building codes have a 3-5 year update cycle. that is, a new edition of the building code comes out every 3 to 5 years. however, due to the length of time that it takes for a jurisdiction to review and approve a new code, the currently enforced version of the local code is often not the most recent edition of the model building code on which the adopted code is base
