Do I need a Walnut Creek business license if my shop is in Concord?
Yes. The city requires a license from any business working inside its limits, contractors and consultants based elsewhere included, even if they already hold another city's license. A contractor based outside Walnut Creek can choose a 90-day license or an annual one, each priced by CSLB license class and neither pro-rated. Apply through the online portal, because City Hall does not take business license applications.
Can I run a crew on a Saturday in Walnut Creek?
Only with an after-hours permit, which the city requires for construction on Saturdays and on City holidays such as November 11 and December 24 in 2026. National holidays like Thanksgiving and Christmas allow no construction at all. On weekdays, permitted construction runs from 7 a.m. to 6 p.m., and power tools in residential areas stay within 8 a.m. to 7 p.m.
Does replacing a window need a permit in Walnut Creek?
Yes. Replacing windows is on the city's own list of work that needs a building permit, and PB-030, the bulletin of exempt work, leaves windows out while it exempts painting, tiling, cabinets and countertops. Apply through the Online Permit Portal from a desktop or laptop, since paper and emailed applications are no longer accepted.
What if a job's mailing address says Walnut Creek but sits outside city limits?
Then the city may not be the one that licenses or permits it. Walnut Creek's business license page warns that unincorporated Walnut Creek is not the same as the city, and links to the county treasurer-tax collector's address lookup so you can confirm which jurisdiction issues the license. Check before applying, so the license and any permit go to the right office.
Will the hot list send me only handyman leads in Walnut Creek?
No. It texts each new Bay Area job as it goes on sale, whatever the trade or city, from 8 a.m. to 8 p.m., so Walnut Creek is one of many areas you will see. Every text names the trade and the area and carries a link that shows the job and its price before you pay. You pay only for the jobs you pick, with no subscription or bidding, and STOP ends the texts.
