Housing Cost Transparency Act

Summary#

The proposed Housing Cost Transparency Act would amend the National Research Council Act. Its goal is to make the costs, expected effects and decision-making around material housing-related national model code proposals more transparent. The supplied material does not state the bill’s status or when it would start.

  • The National Research Council (NRC) would have to prepare, maintain and publish a cost and impact summary for each proposal that could materially affect residential costs, timelines, complexity or administrative burden. It must publish the summary when the proposal first goes out for public review.
  • Summaries must include expected costs and benefits, who is expected to bear the costs, uncertainties and assumptions, and the names and affiliations of individuals recorded as advancing the proposal. If a detailed cost estimate is not practicable, the NRC must provide the best available qualitative description and explain why.
  • The NRC would also have to publish information about relevant committees and their members, plus a contact for technical and process questions during public review.
  • The NRC would have to maintain an accessible, bilingual public registry, including proposal status and milestones, combined estimated impacts for each new code edition, and an annual summary of code work and recurring cost-estimation or transparency issues.
  • The bill says the NRC may support national model code development through research and technical or administrative help, and must publish the codes. It also says provinces, territories and municipal and local authorities retain sole authority over adopting and enforcing codes and other listed local matters.
  • A failure to publish or update the required information would not invalidate a model code or related action by those authorities.

What it means for you#

  • Homeowners, builders and housing developers: You would be able to see estimates of how a covered proposal might affect a typical dwelling, including who is expected to pay. These are estimates, not guaranteed costs or outcomes.
  • People taking part in public review: The proposal’s summary and related information would have to be available when public review begins. The bill does not create a new right to comment or set rules for how comments are considered.
  • The NRC: It would have new publication and information-maintenance duties. The bill does not specify how many staff or what resources the NRC must use.
  • Provincial, territorial and local authorities: The bill says it does not take away their authority over code adoption, permits, inspections, approvals, compliance, enforcement, zoning and other listed local matters. It does not itself adopt a model code as law in any jurisdiction.

Money#

No publicly available information on the bill’s implementation cost is provided in the supplied material.

  • The bill would require the NRC to produce and maintain summaries, committee information and a public registry, but gives no cost or staffing estimate.
  • The cost estimates required for model code proposals are estimates of those proposals’ expected impacts on housing—not estimates of the cost of carrying out this bill.

What is unclear#

  • “Materially affect” is not given a numerical threshold or further test, so it is unclear which proposals would qualify.
  • The bill does not set detailed methods or standards for estimating costs. It allows a qualitative description where a detailed estimate is not practicable.
  • The bill does not set a schedule for updates after initial publication, or explain how the NRC would identify and record everyone who advanced a proposal.
  • It sets no penalty or other remedy for failing to publish; it only says such a failure would not invalidate a code or related action.
  • The National Research Council Act itself was not supplied, so the existing NRC duties and how these changes fit with current law could not be verified. The supplied material also does not state the bill’s status or start date.

Case for#

  • A public estimate could help people understand the likely housing costs and trade-offs of proposed model code changes before they are finalized.
  • Publishing assumptions, uncertainties and who is expected to pay could make estimates easier to assess rather than presenting a single figure without context.
  • Committee membership, affiliations and proposal records could make the code-development process more transparent.
  • Edition-level and annual summaries could help show the combined estimated effects of changes, not just the effects of each proposal separately.

Case against#

  • Cost estimates may be difficult to make reliable. The bill permits qualitative descriptions when detailed estimates are not practicable, so some summaries may provide limited cost information.
  • The bill does not define how much of an effect makes a proposal “material,” leaving the NRC to apply that threshold without criteria set out in the bill.
  • The bill imposes ongoing publication duties but does not specify funding or staffing. That could require additional NRC resources, with no estimate in the supplied material.
  • Because failure to publish would not invalidate a code or related action, the bill does not make publication a condition for those actions to proceed.
