Renovation Contractor in California

For most markets 10% or less of the contract value is a reasonable deposit, sometimes up to 20-30% for jobs with heavy upfront material orders like custom cabinetry. Several countries cap deposits by law. Never pay a large share of the total before work starts, and never pay the full amount up front.

At minimum: full scope of works, itemized price, start and completion dates, payment schedule tied to milestones, who obtains permits, how variations are priced and approved in writing, warranty terms, and how disputes are handled. If a contractor resists putting these in writing, that is the answer to whether you should hire them.

Ask every contractor to break the quote into the same line items: demolition, structural, plumbing, electrical, walls and finishes, fixtures, and a stated allowance for materials you choose. Then compare line by line. A single lump-sum number cannot be compared and cannot be enforced when scope questions come up mid-project.

Manage trades yourself only if the job involves one or two trades and you can be on site regularly. Once a project needs sequencing (demolition, then rough plumbing and wiring, then walls, then finishes), a contractor typically saves more in avoided rework and delays than their 10-20% management margin costs.

A renovation contractor (general contractor or main builder) manages your whole project: pricing the job, scheduling and supervising trades like electricians and plumbers, ordering materials, arranging permits where needed, and being the single party responsible for quality and timeline. You pay one contract price instead of coordinating five separate trades yourself.

Hourly rates typically run $50-$85, but most GCs price renovations as a project with a 10-20% management markup on the trades and materials. Angi's 2025 data puts a full renovation of a 1,250-1,600 sq ft home at around $52,000 on average, with mid-range whole-home work commonly $60-$200 per square foot.

It depends on your state: California, Florida, and most western states require a state licence for jobs above a low threshold, while some states leave licensing to cities or counties. Even where licensing is loose, unlicensed contractors usually can't pull permits — which you'll need for structural, electrical, and plumbing changes.
