Project Map

  1. Year the structure was built

Lead-based paint (LBP) was commonly used in residential and commercial buildings until 1978. Knowing the construction year provides a strong indicator of potential lead presence.

Even if the structure was built after 1978, there is a possibility it could contain lead paint if renovated earlier.

  1. Type of renovation/demolition planned:

Small repairs (e.g., replacing a window) might have lower risk compared to extensive renovations or complete demolition.

  1. Building Materials:

Do you have any existing building renovation or maintenance records that mention lead surveys or abatement work?

  1. Are any of the following materials present in the structure:

  • Paint (especially pre-1978)
  • Older plumbing materials (copper pipes, brass fixtures)
  • Glazing materials in windows (pre-1978)

  1. Visible Damage:

Is there any visible damage to painted surfaces? Peeling, chipping, or cracking paint is more likely to release lead dust.

  1. Occupancy:

Is the structure currently occupied? If so, by whom (residential, commercial)? Renovation/demolition in occupied buildings, especially with children present, requires stricter safety protocols.

If you answered “yes” to any of these questions, it’s highly recommended to consult a licensed lead inspector for a professional survey.

Lead can be found in all parts of our environment – the air, the soil, the water, and inside buildings. Much of our exposure comes from human activities including past use of leaded gasoline, some types of industrial facilities, and past use of lead-based paint in homes. Lead and lead compounds have been used in a wide variety of products found in and around buildings, including paint, ceramics, pipes and plumbing materials, solders, gasoline, batteries, ammunition and cosmetics.
