First, conduct an online search for qualified general contractors in the San Francisco area. Take a few minutes to review their services and decide which contractors are best suited for you. For example, if you need some electrical work done, search for contractors who have completed electrical projects. If you can’t find enough information on their profiles, send the general contractors a message, read customer reviews and view past project photos. 

You should also check to see if the contractor is properly licensed. For example, you can try looking for their license information on their profiles on the Contractors State License Board website. You can also ask the contractors to provide that information.

Finally, ask several contractors in San Francisco to send you free quotes so you can get an idea of how much it will cost to hire a general contractor.
