Timelines vary based on jurisdiction (Sacramento City vs. Sacramento County vs. Placer or El Dorado County), lot conditions, and utility scope. We've seen permits clear in as little as 4 weeks, and we've had others take quite a bit longer depending on the jurisdiction and project. We walk every client through a realistic, property-specific timeline during the feasibility phase, before any design work begins, so there are no surprises.
