Choosing an EPA RRP-Certified Contractor: Verification, Red Flags, and What to Ask
The EPA RRP Rule requires firm-level and individual-level certification for any disturbance of painted surfaces in pre-1978 homes. A pre-hire verification protocol with the questions every homeowner should ask.
The EPA Renovation, Repair and Painting (RRP) Rule (40 CFR Part 745) requires that any contractor disturbing more than six square feet of painted surface in a pre-1978 home, or 20 square feet of exterior painted surface, hold both EPA certification of the firm and certification of the individual renovator on the job. This is binding federal law, not a recommendation.
This piece is the pre-hire verification protocol every homeowner should run before hiring a contractor for renovation, painting, or window replacement in any pre-1978 home.
The two-tier certification structure
The Two RRP Certificates
Firm certification. Issued by EPA to a business entity. Lasts five years. Requires that the firm submit an application, pay a fee (currently $300), and demonstrate that at least one principal employee holds individual renovator certification. The firm certificate is the legal authorization to bid and contract on RRP-regulated work.
Individual renovator certification. Issued to a person. Lasts five years. Requires completion of an EPA-accredited 8-hour training course covering containment, dust control, cleaning verification, and recordkeeping. The individual certificate authorizes that person to direct on-site RRP-compliant work.
The combined requirement: for work to be RRP-compliant, the firm must be certified and at least one certified individual renovator must be on-site to direct the project. A certified firm sending uncertified workers does not satisfy the rule. Likewise, a certified individual working under an uncertified firm’s name does not satisfy it either.
How to verify before hiring
The EPA’s public lookup at epa.gov/lead/find-rrp-firm searches the federal database in real time. Enter the firm’s name and ZIP code (or use the geographic search). Results display certification status, certificate number, and expiration date.
The EPA lookup confirms firm certification. To verify the individual renovator who will be on-site, ask the contractor for their EPA-issued certified renovator card. The card has a photo, the renovator’s name, an EPA-issued identifier number, and an expiration date. Confirm the date is current.
A firm advertising “RRP Certified” or “Lead-Safe Certified” without a verifiable EPA certificate number is a red flag. Reputable contractors include their EPA certificate number on estimates and contracts as a matter of course.
Questions every homeowner should ask
Before signing a contract, work through this list with any prospective contractor:
Questions to Ask Before Signing
1. “What is your firm’s EPA RRP certificate number?”
Reputable contractors answer immediately. If they hesitate, deflect, or claim they don’t need one because the work is “minor,” disqualify them.
2. “Who specifically will be the certified renovator on-site?”
The answer should be a named person whose individual certification you can also verify. If they say “the foreman” without naming who, push back.
3. “Will you provide me with the EPA-required pre-renovation pamphlet?”
The RRP rule requires contractors to deliver EPA’s Renovate Right pamphlet to homeowners before work begins. Contractors who don’t know about this pamphlet are not following the rule.
4. “What is your containment and cleaning protocol?”
The right answer references plastic sheeting, HEPA-equipped vacuums, wet-cleaning of horizontal surfaces, and post-work dust-wipe verification. Generic answers (“we’ll be careful”) indicate the contractor does not actually understand the rule.
5. “Do you do clearance testing after the work?”
The RRP rule requires the renovator to perform a “cleaning verification” — a specific protocol with white cleaning verification cards. Some homeowners go further and pay for independent third-party clearance testing (dust-wipe sampling sent to an EPA-certified lab). For homes with young children, third-party clearance is the more rigorous standard.
6. “What is your record-retention policy?”
The RRP rule requires contractors to retain project records for three years. A contractor who cannot describe how they document compliance is unlikely to be doing it.
Red flags that should disqualify a contractor

The third red flag is particularly common. The RRP Rule exemption for “minor repairs” applies only to projects disturbing less than six square feet of interior painted surface or less than 20 square feet of exterior. Any window replacement automatically exceeds these thresholds. Any room repaint exceeds them. Most “minor repairs” claims are either misunderstanding or evasion.
What about owner-occupants doing their own work?
The RRP Rule does not regulate work performed by an owner-occupant on their own residence — federal law does not require a homeowner to be RRP-certified to renovate their own home. However: the EPA strongly recommends that homeowners follow RRP-equivalent practices, and several states (including Massachusetts, Connecticut, and Rhode Island) impose state-level requirements that do apply to owner-occupants of housing built before specific cutoff dates.
For the work itself, the Lead Paint Field Guide describes the containment and verification protocol RRP-compliant contractors follow. A homeowner who replicates that protocol — plastic containment, HEPA vacuum, wet-cleaning, dust-wipe verification — is producing work substantially equivalent to RRP standards, even where federal certification is not required.
After the work: clearance verification
Independent third-party clearance is the gold standard for verifying RRP-compliant work in homes with young children:
- After the contractor completes work and performs the EPA-required cleaning verification, hire an independent EPA-certified inspector (not the same firm that did the work) to perform dust-wipe sampling.
- The inspector takes wipe samples from floors and window sills and submits them to an EPA-certified analytical lab.
- Results return in 3–7 business days. The pass thresholds: 10 µg/ft² on floors, 100 µg/ft² on window sills, 400 µg/ft² on window troughs.
- If the home passes, you have lab-documented evidence of safe re-occupancy. If it fails, the contractor is generally responsible for re-cleaning and re-testing at no additional cost.
The cost: typically $300–$600 for a single-family home. For a project costing $10,000+, the verification is usually worth it.
