Short answer: look up the license on the CSLB website, get at least two written bids that describe the same work, make sure whoever you hire pulls the permit with the City of Vacaville, and keep the down payment at or under the state cap. I live here and I build for a living, so this is the checklist I use on my own house.
Where do people in Vacaville find contractors?
Mostly through neighbors, Nextdoor, and local Facebook groups, which is a fine place to start as long as you verify every name before you hire.
A neighbor's recommendation tells you someone showed up and the neighbor was happy. It does not tell you whether the license is active, whether the work was permitted, or whether the job was anything like yours. Treat a recommendation as a name to check, not a name to hire.
How do I check a contractor's license?
Search by name or license number on the Contractors State License Board's Check a License page and confirm the license is active and matches the kind of work you need.
The CSLB lookup is free at cslb.ca.gov, and it lets you search by license number, business name, or personal name. It also shows complaint disclosure.
Match the classification to the job. Electrical work falls under C-10. Roofing is C-39. A general building contractor holds a B. If the license on the truck does not match the work in your house, ask about it before you sign.
Small jobs have their own rules, and a handyman is not the same as a licensed contractor. The difference is worth two minutes of reading before you hire anyone for a job that needs a permit.
Does my project need a permit in Vacaville?
Many common jobs do, including re-roofs, water heaters, and electrical service change-outs, and the City of Vacaville Building Division issues them.
The city runs permits through its online portal, eTRAKiT. It lists like-for-like jobs such as re-roofs, water heaters, and electrical service and subpanel change-outs under 200 amps as basic residential replacement permits, and says those can be issued instantly when nothing new is being added. Bigger residential projects go through plan review, and the city runs a Plan Check Express program for eligible residential projects.
Contractors apply with their own contractor login, and the city does not let them apply under a public account. If a contractor asks you to pull the permit yourself as the owner, ask why. Whoever holds the permit is responsible for the work.

- Outside city limits: if your address is in unincorporated Solano County, permits come from Solano County Resource Management, Building and Safety Services, 675 Texas Street, Suite 5500, Fairfield. 707-784-6765.
Does a contractor need a Vacaville business license?
The city issues business licenses to operate within Vacaville city limits and lists contractors as one of the license classifications, so it is a fair thing to ask about.
A state contractor's license and a city business license are two different things. The state license says they are qualified. The city license says they are set up to do business here. A contractor who works in town regularly will know exactly what you are asking about.
How many bids should I get?
Two or three written bids that describe the same scope of work, so you are comparing prices for the same job.
More bids is not better if they describe different jobs. Before you compare numbers, make sure each bid names the same materials, the same prep, and the same cleanup. When one comes in far lower, look for what it left out before you celebrate.
How much can a Vacaville contractor ask for up front?
No more than $1,000 or 10 percent of the contract amount, whichever is less, under California law.
That cap is Business and Professions Code section 7159.5(a)(3), and it applies to home improvement work everywhere in the state, Vacaville included. After the down payment, payments should follow work that is actually done.
Full disclosure: I run YouSuperIntendIT. You can post your project there for free and put it in front of local contractors and skilled trades, or ask AskTim a question about a quote you already have, also free.
