SUMMARY:[RESEARCH] Why Ohio's contractor licensing system creates a moat for transparent directories: the four state-licensed trades\, the ten that aren't\, and what honest verification looks like in 2026
DESCRIPTION:Ohio's OCILB licenses only four trades: plumbing\, HVAC\, electrical\, and hydronics. Roofing\, concrete\, tree service\, appliance repair\, and most other home-services categories are not state-licensed\, so honest directories need asymmetric verification.

SUMMARY:[RESEARCH] Permit volume vs star ratings: what 21\,000 Ohio contractor records actually show
DESCRIPTION:Cross-tabulating 21\,000+ Ohio contractor records against permit and star-rating data\, ProFix Directory finds the two signals barely correlate. Star ratings reward marketing and responsiveness\; permits reward doing the work legally. Homeowners should weight them independently.

SUMMARY:[RESEARCH] Ohio vs. the nation — what 50-state home-services data transparency really looks like in 2026
