Any renovations that don’t involve structural changes to the property, like increasing the ceiling height or square footage, are eligible for express permits, which can be obtained immediately online. But if you plan on initiating structural changes to your home, then you will need to study your area’s zoning laws and building information. Every home is subject to various sorts of zoning laws that must be considered before any permit can be obtained. Various agencies and departments may need to receive approval, including:

  • Department of Public Works
  • Department of Transportation
  • Housing Authority
  • Fire Department
  • Department of City Planning
  • Community Redevelopment Agency
  • Department of Cultural Affairs
  • Los Angeles Unified School District
  • Office of Oil and Gas
  • Occupational Safety and Health Administration

  • Los Angeles Department of Water and Power

The permits you need will largely depend on the scope of your room addition. Depending on your project, you may require the following permits:

  • Electrical: If you engage in any electrical work with your room addition.
  • Fire Sprinkler: If your room addition includes fire sprinkler installation or modification.
  • Mechanical HVAC: If you intend on setting up any heating, ventilation, or air conditioning for the new room.
  • Elevator/Pressure Vessel: If adding the new room involves installing or modifying elevators, escalators, or dumbwaiters.
  • Grading: If grading work occurs on a hillside grading area or if re-compaction or removal occurs. Backfill will also require this permit.
  • Plumbing:  If the project requires installing or modifying water pipes, drainage systems, or lawn sprinkler systems.

Your project may also be reviewed for accessibility and environmental impact, but this may depend on the scale of your room addition.

What Is the Permit Process for An Addition to an Existing Home?

If you are ineligible for an express permit, you will likely need to submit various plans, ideally with the assistance of an engineer. Any calculations shown in your plans must be attributed, stamped, and signed by the engineer. The following plans will be required:

  1. Plot: Put together a drawing of your property with all structures included and dimensions accurately labeled.
  2. Floor Plans: Floor plan with accurate dimensions of the existing property and a floor plan of your proposed renovation.
  3. Framing PlanThe framing plan is normally conducted by engineers. It involves detailing the sizes and spacing of various aspects of the building’s framework.
  4. Foundation PlanThe drawing and details of your proposed foundation.
  5. Elevation Plan: Proposed elevations of your project.
  6. Construction Details: The details of your plan to put together your construction components while complying with requirements and regulations
  7. Energy & Water Conservation: How your room addition will comply with all energy conservation requirements.
  8. Information Bulletin of Prescriptive Provisions: Bulletin containing the latest information regarding directives and plans.

Once these plans have been submitted, they will be reviewed by local officials. You may have to make corrections and obtain more clearances afterward, which can take additional weeks. When everything is corrected and all clearances have been obtained, you can resubmit your plans, which require an additional weeks of review.

When you have finally received the permit, you will be allowed to work on the project within two years. If the work doesn’t commence within six months from obtaining the permit or if your project ceases for six months, your permit will expire. Now that you’ve obtained the permit, you can move forward with your room addition. At various points of the construction process, the project will be inspected. To determine when this occurs, you should reach out to your local office. If all inspections are satisfactory and the room addition is completed, a certificate of occupancy will be issued.
