Questions

How much does a new deck cost in California?

For a 300 sq ft deck with 30 ft of railing, our mid-finish likely budget is $18,300 to $21,100 across eight California cities (Fresno lowest, San Francisco highest). Your own size, finish and ZIP change this; the free estimator recalculates it line by line.

Why do costs vary so much by city?

Mostly labor. We price each trade at the hourly rate a contractor bills in your county, built from Bureau of Labor Statistics wages, payroll taxes, California workers' comp rates and contractor overhead. Sales tax and permit fees also vary by county and city.

Does the estimate include permits and contractor profit?

Yes. Permit fees are estimated from the job's valuation. When three or more trades are involved, a general contractor overhead and profit line is shown separately; single-trade jobs are priced at the trade's billed rate only.

Is this a quote?

No. It is a budget estimate, not a bid, appraisal, or insurance claim valuation. Get written bids from licensed contractors, and check licenses with the Contractors State License Board.
