Key Risks for 1970s Homes
- Lead paint (pre-1978 portion)
- Asbestos in insulation & tiles
- Polybutylene pipes (late 1970s)
- Single-pane windows
- Original HVAC nearing end of life
Homes built before 1978 contain lead-based paint. The 1970s also introduced polybutylene pipes in some markets — a material prone to cracking that was subject to major class-action litigation. Late-decade homes may already have passed the lead-paint threshold but can still have asbestos insulation.
What to Inspect
Ask specifically about polybutylene pipes (grey, flexible plastic). Homes with poly-b may need full replumbing. For pre-1978 construction, a lead paint inspection is recommended before any renovation.
Note for Oklahoma: Homes built before 1978 require lead paint disclosure under federal law. Oklahoma may have additional state-level requirements for lead testing.
