Painting a Pre-1978 Home in Portland: Lead Paint, Prep, and Safety

Roughly 60 percent of single-family homes in the Portland metro area were built before 1978, which means most older Portland houses have at least one layer of lead-based paint somewhere on the structure. Painting these homes is not harder than painting newer ones, but it does require lead-safe work practices that protect your family and the painter's crew. This guide explains what those practices look like, why they matter, and what to expect from a properly certified painter.

Why 1978?

Lead was a common additive in residential paint through most of the 20th century because it improved durability, color retention, and moisture resistance. In 1978 the federal government banned lead in residential paint after decades of evidence linking it to neurological damage in children. Homes built after that date were finished with lead-free products, and remodeling them does not trigger lead-safe rules. Homes built before that date almost certainly have lead paint somewhere, often buried under several newer coats.

The EPA RRP rule, in plain language

The Lead Renovation, Repair, and Painting (RRP) rule has been federal law since 2010. It says: anyone disturbing more than 6 square feet of interior painted surface or 20 square feet of exterior surface on a pre-1978 home must follow specific work practices, and the firm doing the work must be EPA certified. The certification has two parts:

• Firm certification. The painting company itself is registered with the EPA. Required to do RRP work.
• Certified renovator. At least one individual on the crew has completed an 8-hour EPA training course. They supervise the work, set up containment, and verify cleanup.

Both are public information. Ask your painter for the firm certification number, which starts with "NAT-" followed by 6 digits. You can look up firms at the EPA's RRP search tool.

What lead-safe work practices actually look like

A properly run pre-1978 exterior job looks like this:

1. Containment. 6-mil plastic sheeting laid on the ground extending at least 10 feet from the work area (further on multi-story homes), with edges weighted or taped down to keep paint chips from escaping. Plants and walkways are covered or moved.
2. No open dry-sanding or burning. Sanding is done with a HEPA-vacuum attached sander. Open flames and heat guns above 1100 degrees are prohibited because they aerosolize lead.
3. Wet methods. Scraping is done on damp surfaces to reduce dust. Paint chips fall onto the containment, not into the soil.
4. HEPA cleanup. Daily HEPA vacuum of the containment, with all collected debris bagged and labeled.
5. Cleaning verification. At job completion the certified renovator runs a "cleaning verification" step wiping representative surfaces with disposable wet wipes and comparing to a reference card. If the wipes pick up significant residue, the area gets cleaned again.
6. Waste disposal. Lead paint waste is bagged and disposed of as construction debris (no special hazmat handling required at the residential scale for typical amounts).

Cost impact

Lead-safe practices add real time to the job. Expect 15 to 30 percent on top of the base paint cost, typically $800 to $2,500 on a normal Portland home exterior. Costs are higher when paint is significantly failing and there is a lot of scraping to do, lower when the existing paint is in good shape and you are just doing a maintenance recoat.

The cost is not negotiable. A painter who quotes well below others on a pre-1978 home is almost always skipping the protocol. That puts your family at risk and exposes the contractor to EPA fines up to $37,500 per violation. It also means contaminated soil around your home that may need remediation later.

Why this matters more in Portland than most cities

Portland has one of the older housing stocks among major Pacific Northwest cities. Inner east-side neighborhoods (Irvington, Laurelhurst, Sellwood-Moreland, Mt Tabor, Sunnyside, Buckman, Richmond, Hawthorne) are dominated by pre-1940 craftsman and bungalow construction. Inner north and northeast (Alberta, Boise, Overlook, Piedmont) similarly. Even much of suburban Beaverton, Tigard, and Milwaukie has substantial pre-1978 inventory. If you own a Portland home and you are not sure of the year built, check the county assessor record (Multnomah, Washington, or Clackamas) before getting quotes.

Health risks (the short version)

Lead poisoning is most dangerous for children under 6 and pregnant women. Even low-level chronic exposure can cause developmental and cognitive problems that are not reversible. The two primary exposure paths during renovation are:

• Inhaled dust from dry-sanding or improper containment, especially indoors.
• Soil contamination from paint chips that fall outside the work area and get tracked back into the house on shoes or pets.

Properly run RRP work nearly eliminates both. Improperly run work creates an exposure problem that can outlast the paint job by years.

Practical checklist before you sign

• Confirm year built. If 1978 or later, no RRP needed.
• If pre-1978, ask for the firm RRP certification number.
• Confirm the certified renovator will be on-site during work.
• Ask to see their containment setup on a prior job (photo is fine).
• Ask what the cleanup and verification step looks like.
• If kids under 6 live in the home, keep them and pets out of the work area during all phases of the project.
