With two exceptions, the requirements described above apply to residential
buildings on the bill's effective date. The first exception applies to a residential
building in which all of the fuel-burning appliances are inspected as provided under
DATCP or DSPS rules. If a residential building is subject to that exception, the bill's
requirements do not apply until approximately 18 months after the bill's effective
date. The second exception maintains the exception under current law for a
residential building in which all of the fuel-burning appliances have sealed
combustion units that are covered under the manufacturer's warranty. Under that
exception, the bill's requirements do not apply to such a residential building.
The bill also makes the following changes:
1. The bill allows DSPS and DATCP to inspect buildings under their
jurisdiction for compliance with carbon monoxide detection requirements. Current
law requires, instead of allows, the inspections.
2. Current law requires building inspectors certified by DSPS to inspect
residential buildings for compliance with carbon monoxide detection requirements.
The bill eliminates the reference to building inspectors and allows, instead of
requires, a person to make an inspection if he or she is certified under DSPS rules
to inspect public buildings, places of employment, or fire detection, prevention, and
suppression devices.
3. If an inspector described above gives written notice to a residential building
owner that a carbon monoxide detector is not functional, then, within five days of
receipt of the notice, the bill requires the owner to provide any maintenance that is
necessary to make the carbon monoxide detector functional.
Examinations. The bill also eliminates certain prerequisite degree
requirements to sit for an examination for licensure by the Marriage and Family
Therapy, Professional Counseling, and Social Work Examining Board. The bill does
not alter the education requirements for licensure by that board but, instead, allows
applicants for licensure to take the examination before completion of those education
requirements.

Training certificate. The bill provides that the term for which a social worker
training certificate is valid is 24 months. Current law includes an exception that
provides for a shorter term based on a certificate holder's receipt of his or her national
social worker examination results. The bill eliminates that exception.
For further information see the state and local fiscal estimate, which will be
printed as an appendix to this bill.
