Free practice questions for the California CSLB B-2 Residential Remodeling trade exam — with a written explanation on every answer, in English, Spanish, and Russian.
The B-2 Residential Remodeling exam is the trade test for a classification California added in 2021: improvements to an existing residential wood-frame structure where a single contract requires three or more unrelated trades. CSLB's official study guide splits the exam into six areas — planning and estimating, job site preparation, core trades, finish trades, exterior remodeling and safety. Practice it below: free, no sign-up, with a written explanation on every question.
No account needed. Pick an answer to see whether it's right and read the explanation — the same explanations you get on every question in the full course.
Every question tells you why the correct answer is correct and defines the terms it uses — so you learn the rule, not just the answer.
Questions are written from scratch against the official codes and agency publications for this exam — never copied from the real exam.
Every question and explanation is fully translated, with the English exam term kept alongside — not a shallow machine translation.

The full B-2 Residential Remodeling course is 500 questions across 5 blocks, drawn from these six official exam areas.
About 15% of the exam. You read plans and specifications, spot design and construction errors, check scope against code, coordinate the trades, and price materials, equipment and labor. Expect arithmetic: quantities with a waste allowance, rental equipment with markup, labor hours. A calculator is provided, so the trap is rarely the math itself — it is dropping the waste factor, or pricing a room and forgetting that cartons, sheets and gallons only come in whole units. The business side of pricing and contracts is drilled separately in the CSLB Law and Business practice test.
About 13%: removing non-load-bearing walls, pulling out cabinets and countertops, taking out plumbing and electrical fixtures, and delivering and storing materials. The item that costs B-2 candidates points is the wall. The classification statute lets a B-2 remove partitions that carry no load, but bars contracting for structural changes to load-bearing portions — footings, foundations, bearing walls and roof structures — and, unlike the other limits in that section, this one has no "subcontract it instead" option. Demolition in a house built before 1978 also puts you under the federal lead rule before the first pry bar comes out.
The largest section at about 25%: plumbing, electrical, mechanical, interior walls, ceilings and trimwork, flooring and stairs. Know exactly where B-2 scope ends. You may install, repair or replace fixtures — faucets, sinks, toilets, tubs, dimmers, fans, lights, outlets, switches, filters, grills, preassembled exhaust fans — and make the minor alterations those fixtures need. Installing, replacing, substantially altering or extending the systems themselves takes the matching classification or an appropriately licensed subcontractor. Moving a shower or extending a circuit is system work; swapping a faucet is not. The electrical half of that line is drilled in the C-10 Electrical practice test.
About 18%: cabinets, countertops and backsplashes, painting, staining, coating and interior wall covering, fireplaces and mantels. Questions here turn on sequence, substrate and clearance — what goes on before what, what a covering may be applied over, and how close combustible trim may sit to an opening. Glass belongs to this half of the job too: a new shower or bathtub enclosure is a Category II product under the federal architectural-glazing standard, so ordinary annealed glass is not what goes in.
About 13%: roof repairs, remodeling exterior walls, doors and windows. Watch the scope line again — repairing a roof covering sits inside the B-2 classification, while altering the roof structure is a structural change and does not. Window and door work carries its own baggage: safety glazing where a person can fall against it, flashing and weather-resistive barriers behind siding, and the fact that a window replacement never counts as "minor repair and maintenance" under the federal lead rule, no matter how small the opening.
About 16%, split between personnel safety, job site safety, and demolition and material safety. California does not follow the federal numbers, and that is where candidates lose points: the state's Construction Safety Orders require an approved personal fall arrest or fall restraint system where work exposes an employee to falling in excess of 7 1/2 feet — not the 6 feet you may have learned from federal OSHA. Lead is the other half. Renovation for pay in housing built before 1978 requires an EPA-certified firm and lead-safe work practices: open-flame torching is prohibited, a heat gun must stay below 1,100 °F, and paint-removal machines need a shroud and a HEPA vacuum. If you also handle refrigerant, the same "get certified before you touch it" logic drives the EPA 608 practice test.
The B-2 exam is closed book — no reference materials in the room — and multiple choice with four choices per question and one BEST answer. Some questions require computation and a calculator is provided; there is no penalty for guessing, so leave nothing blank. You take it on a computer at a PSI testing center, with 3.5 hours per exam, the limit published in CSLB's official Examinations FAQ. The result is pass/fail on the spot; a failing report breaks your score out by section, and you may retake after 21 days within your application's 18-month window. B-2 is not one of the ten exams CSLB publishes in Spanish, so the trade exam is given in English — CSLB allows an approved translator for exams with no Spanish version.
The LICENA B-2 course is 500 questions in five blocks. At 30 questions a day that is about three weeks: one pass to find out what you do not know, a second to close it, and a few days on your two weakest sections before test day. Weight your time the way the exam does — core trades and safety together are more than 40% of it. Read the explanation on every question you miss, including the ones you guessed right; the exam rewords facts, so understanding why a wall may or may not come out travels, while memorizing answer letters does not. Pair the practice with CSLB's own B-2 study guide, and treat any product that promises a guaranteed pass as a warning sign.
