Before you hire in Southfield
Lead-safe work rules apply to most homes
The typical home in Southfield was built around 1969. Painting, window, siding and remodeling work that disturbs paint in homes built before 1978 must follow the EPA lead-safe (RRP) rule. Ask any contractor for their RRP certification before work starts.
Mid-century and newer systems
Most homes here date from 1969 or later. Original furnaces, water heaters and roofs from that era are well past their service life, so replacement planning matters more than repair.
Permits: check with the Southfield building department before work starts.
