- If your property doesn't appear in ZIMAS, you may not be within the City of Los Angeles, and will require service from another County department. Use the Online Service Locator from the LA County Dept of Public Works to find out who services your area.
- Design your project and draw plans
- Submit plans and complete a permit application at an LADBS office
- Note: If your project falls under any of the construction types in Express Permit (pdf), you do not need your plans checked. You may complete a permit application at an LADBS office or online.

- Plans are approved by LADBS and a permit is issued, which may be picked up at an LADBS office.
- Construction begins, and inspections are requested while construction is occurring.
- There are many different inspection types, and inspection requirements depending on the project. You must have an inspection done on relevant construction before any work is covered or concealed.
