Fixed-price contracts give you cost certainty: you know the exact cost before starting. Cost-plus contracts bill actual costs plus a markup. Fixed-price is better for most LA homeowners because it transfers risk to the contractor.
You and the contractor agree on a total price before construction begins. The price doesn't change unless you request changes (change orders). Pro: cost certainty, contractor absorbs overruns. Con: requires detailed scope upfront, contractor builds in contingency. Best for: most residential projects. NP Line Design uses fixed-price for all projects.
Contractor bills actual costs (materials, labor, subcontractors) plus a fee (typically 15-20%). You see every receipt. Pro: transparency, flexibility to change scope. Con: no price certainty, incentive to overspend. GMP (Guaranteed Maximum Price): adds a ceiling — contractor eats costs above the cap. Better than open-ended cost-plus.
Contractor bills hourly labor rates + material costs. No total price established. Pro: flexible for undefined scope. Con: most expensive, no cost control, disputes over hours. Best for: small repair projects under $5,000 where scope is truly uncertain. Never use T&M for a remodel or addition.
Written modifications to the original contract. Should include: description of change, cost impact (positive or negative), time impact, and both parties' signatures. Verbal change orders are not enforceable. Keep a change order log throughout the project. NP Line Design's design-build process minimizes change orders by finalizing decisions before construction.
California Home Improvement Contract law (B&P Code 7159) requires: contractor's license number, 3-day right to cancel, payment schedule, description of work, estimated start and completion dates, and warranty information. Contracts over $500 must be in writing. Non-compliant contracts are voidable by the homeowner.
