Lead-Based Paint Renovation License

Requirements for pre-1978 structures
Oregon enforces federal regulations for contractors working on housing or child-occupied facilities built before 1978. Under these requirements, only contractors who are licensed for Lead-Based Paint Renovation can bid or work on pre-1978 homes.

The goal: Use lead-safe work practices and reduce the risk of lead poisoning.

Do I need a special license?
Homes and child-occupied buildings such as daycare centers, preschools and kindergarten rooms constructed before 1978 are presumed to have lead paint unless testing shows otherwise. This means that you cannot bid on a renovation project until you complete an approved training class and obtain a Lead-Based Paint Renovation License.

Renovation means modifying any structure or part of a structure that disturbs more than:
- Six square feet of painted surface per room for interior work.
- 20 square feet of painted surface for exterior work.

This includes projects involving flooring, windows, gutters, siding, and painting. Window replacement is considered renovation.
