Summary
Longmont's amended International Existing Building Code lets a home caring for five or fewer children, or five or fewer people receiving custodial care, stay classified as a Group R-3 residential occupancy instead of a commercial Group E or institutional Group I-4 use. The exception, at Municipal Code section 16.40.200, spares small in-home day cares from the sprinkler retrofit section 803.2 would otherwise force during renovation work.
Section 803.2 of the International Existing Building Code is amended by addition of the following three exceptions: Exception: 1. Group E, day care facilities. Five or fewer children in a dwelling unit. A facility such as the one described in section 305.2.3 of the International Building Code within a dwelling unit and having five or fewer children receiving such day care shall be classified as a Group R-3 occupancy or shall comply with the International Residential Code. 2. Institutional Group I-4, day care facilities. Five or fewer persons receiving care in a dwelling unit. A facility such as the one described in section 308.5.4 of the International Building Code within a dwelling unit and having five or fewer persons receiving custodial care shall be classified as a Group R-3 occupancy or shall comply with the International Residential Code. 3. Residential Group R-3, care facilities. Care facilities that provide accommodations for five or fewer persons receiving care located within a single-family dwelling shall comply with the International Residential Code.
Full Breakdown
04's rules for new construction. 2, the provision that forces an automatic sprinkler retrofit when an existing building's occupancy or use changes, by adding three named exceptions for small in-home care. 4. Both may stay classified as a Group R-3 residential occupancy, or comply with the International Residential Code instead of the commercial sprinkler standard. The third exception covers a Group R-3 care facility itself, five or fewer people receiving care inside a single-family home, which likewise only has to meet the International Residential Code.
2, the fire protection system trigger, so a small home day care gets the same five-person relief from both the sprinkler mandate and the fire alarm mandate. 130 fixes 'child' at 12 years of age or younger for the whole chapter, the age line that counts toward the five-child cap. Once a facility exceeds five children or five persons receiving care, none of the three exceptions apply and the operation is treated as a full commercial or institutional occupancy for any renovation, addition or change-of-use permit, meaning sprinklers and fire detection built to the base IEBC standard. The current version of this chapter, including these day care exceptions, was adopted by Ordinance No. 04 now covers only appeals procedure.
Violations & Fines
Section 16.40.120 makes it unlawful to erect, alter, occupy or maintain a building in violation of Chapter 16.40, including running a day care outside these exceptions without the sprinkler or fire protection upgrade the base code requires. Each day the violation continues is a separate offense, punishable under Chapter 1.12 of the Longmont Municipal Code. The building official can order correction regardless of any penalty already imposed, and the city attorney may pursue a violation as a public nuisance in court in addition to any citation.
