The Permit Roadmap for ADUs and Small Builds in San Diego County

By Thankful RealtyDecember 11, 20266 min read

Permits feel like a wall until you see them as a path. This roadmap breaks the city process into twelve steps. Check off what you have done and see what comes next.

Quick takeaways
  • Permits are a process, not a wall
  • Early checks save the most money
  • Fast, complete answers keep plan check moving

The big stages

  1. Idea and feasibility: What you want, what the lot allows, and a rough budget.
  2. Design: Plans from a designer, architect, or engineer.
  3. Submittal: Your application and fees go to the city or county.
  4. Plan check: Reviewers send comments. You answer them.
  5. Permits and building: A licensed contractor builds and inspections happen along the way.
  6. Final: Final inspection and sign off.

Where projects get stuck

  • Missing information in the application
  • Utility capacity or fire access surprises
  • Slow answers to plan check comments
  • Plans that do not match the rules

Common questions

How long do permits take?

It depends on the city, the project, and how complete your plans are. A feasibility review gives you a more realistic range.

Do I need an architect or engineer?

Many projects need a designer and sometimes an engineer. Requirements depend on the project and the jurisdiction.
