Most of these are avoidable with an afternoon of attention. All of them are things I have watched happen to real people.
Washington is accessible to start in, but the state does enforce. Here are the seven ways new contractors trip — and the fix for each.
Doing contracting work — even a favor — before your registration is active is an infraction and destroys your ability to collect. Fix: wait for active status. Full stop.
Registration checks financial responsibility. An outstanding judgment or unpaid tax balance can block or pull a registration under RCW 18.27. Fix: clear or formally resolve debts before you apply.
This is the one I take personally, and I will be straight about it: I have seen a contractor registration blocked over an unsatisfied judgment tied to an old business. The state does check, and it does not care how good you are with a pipe wrench. If you have any open judgment or state balance, deal with it head-on before you file — a payment plan on record is far better than a surprise denial. This is exactly the kind of thing to fix first, not discover at the counter.
Your registration depends on active bond and insurance. If either lapses, your registration can be suspended. Fix: calendar the renewals; do not let them auto-cancel for a missed payment.
UBI, bond, insurance certificate, and application must match exactly. Fix: pick the exact name once and reuse it everywhere (start here).
Ads, cards, and bids must show your number. Fix: add it to every template before you publish anything.
Calling a directed, hourly helper a “subcontractor” can leave you owing back workers' comp premiums and penalties. Fix: apply the state's tests honestly; when in doubt, report the hours.
An unregistered sub on your job is your liability. Fix: verify every sub on the L&I verify tool before they start.
