  • Statement of Scope
    Department of Safety and Professional Services
    Rule No.:
    Chapter SPS 322
    Relating to :
    Crawl Space Ventilation
    Rule Type :
    Permanent
    1. Finding/nature of emergency (Emergency Rule only):
    Not applicable.
    2. Detailed description of the objective of the proposed rule:
    The objective of this rulemaking is to eliminate the requirement for crawl space ventilation in one- and two-family dwellings .
    3. Description of the existing policies relevant to the rule, new policies proposed to be included in the rule, and an analysis of policy alternatives:
    The Uniform Dwelling Code currently requires uninsulated crawlspaces to have ventilation openings equal to at least 1/1500 of the floor space and requires the floor above to be insulated. The alternative is to insulate the crawlspace walls, in which case, venting is not allowed. The proposed rule eliminates the venting option and thus requires crawl space walls to be insulated. The alternative of not updating the Code would be that crawl space ventilation would continue to be allowed.
    4. Detailed explanation of statutory authority for the rule (including the statutory citation and language):
    Section 227.11 (2) (a) of the Statutes authorizes the Department to promulgate rules interpreting any statute that is enforced or administered by the Department, if the rule is considered necessary to effectuate the purpose of the statute.
