Home improvements normally involve separate approvals from the Planning Division and the Building & Safety Division of the Department of Environmental Services. Regarding custom homes, approval from the Department of Public Works may be required.

How would you like to improve your home?

Would you like to add on to your home, such as for a room addition?

First, ensure your proposal meets the City’s standards by reviewing the Sample Plot Plan and Minimum Setbacks exhibit. Before you proceed, we recommend that you visit the Planning Division for a preliminary review of your proposed project. Our Planning staff will review your property’s characteristics and inform of your parameters, including setbacks, height, special conditions, and any additional circumstances to consider when preparing your proposal. If you have any questions, please contact Planning at (805) 583-6769 or enviroservices@simivalley.org.

Now that you know your parameters, you or your contractor/architect will need to prepare the plot plan, floor plan, and building elevations. Submittal requirements and sample plans can be found on the City’s Sample Plot Plan and Minimum Setbacks and Residential Addition Submittal Requirements.

When your plans are ready, you will need to bring them in to Planning, where a staff Planner will review them to ensure all zoning requirements and standards are met. If they are, a Zoning Clearance will be issued. If changes are necessary, the Planner will work closely with you to ensure that your revised plans meet all City standards.

Now that you have your Zoning Clearance, your next step is to obtain a Building Permit. You will need to submit an application with drawings and plan check and permit fees. Specific submittal requirements can be found at Building & Safety Division. Note that the plans you prepare for Building & Safety can also be used for Planning in obtaining a Zoning Clearance. You may also contact the Building Division at (805) 583-6723 or enviroservices@simivalley.org for information. Please note that certain restrictions may apply if you are in a Special Flood Hazard Area.

Would you like to replace the windows in your home?

You will need to obtain a Building Permit from the Building & Safety Division. First, complete an application and submit it to the Building & Safety Division with the plan check and permit fees. Please contact the Building & Safety Division at (805) 583-6723 or enviroservices@simivalley.org for information.

A Zoning Clearance is not required for window replacement; however, we also recommend you contact your Homeowners Association (if applicable) for any additional restrictions.

Would you like to replace your water heater, furnace, or air conditioner, or perform other minor plumbing or electrical work?

You will need to obtain a Building Permit from the Building & Safety Division for the replacement, relocation, or installation of water heaters, furnaces, air conditioning units, electrical panels, or for any other minor plumbing/electrical work.

First, complete an application and submit it to the Building & Safety Division with the plan check and permit fees. Please contact the Building Division at (805) 583-6723 or enviroservices@simivalley.org for more information.

For replacement only of an existing air conditioning unit, you will not need Planning Division approval. However, if you would like to relocate an existing unit or install a new one, you will first need to contact the Planning Division to verify if you need a Zoning Clearance. You may need to prepare a simple plot plan showing that the unit’s location meets the City’s minimum setback requirements.

Refer to Sample Plot Plan and Minimum Setbacks for details, or contact Planning at (805) 583-6769 or enviroservices@simivalley.org for assistance.

Would you like to add a fence or wall?

First, ensure your proposed fence or wall meets the City standards for location, type, and height by reviewing the Residential Fences and Walls Exhibit and SVMC Section 9-30.050 ”Height and Location Requirements for Fences, Walls, and Hedges." You may also visit the Planning Division, and a staff Planner will assist you with options based on your individual property. If your yard is adjacent to a major arterial street and/or a commercial/industrial zone, your property line wall or fence may be allowed to be up to eight feet in height.

Next, prepare a plot plan (refer to Sample Plot Plan and Minimum Setbacks) showing the location, type, and height of the proposed wall or fence, and submit it to the Planning Division. If all requirements and standards are met, a Zoning Clearance is issued.

For most residential fences and walls, a Building Permit is not required. However, if you are planning to build a wall or fence over six feet in height or a retaining wall, a Building Permit may be required, in addition to a Zoning Clearance.

Please check with the Building & Safety Division at (805) 583-6723 or enviroservices@simivalley.org for more information.

Would you like to add a paved driveway or patio?

First, refer to the Front Yard Landscaping Requirements on Single-Family Lots exhibit to determine whether your proposed paving meets the City standards for maintaining the minimum landscaping in the front yard. While paving in the side and rear yards does not require a City permit, paving anywhere in the front yard area does require a Zoning Clearance from the Planning Division; however, a Building Permit is not required.

The City standard requires that at least 50 percent of the front yard be landscaped. Note that up to 100 percent of the required landscaping can consist of artificial turf, although the artificial turf appearance will be improved with some natural plantings mixed in with the turf. Within the front yard, you are allowed to maintain, at a minimum, a driveway to the garage, a ten-foot wide strip of paving along side the driveway that is nearest to side property line, and a sidewalk to the front door.

Next, prepare a plot plan showing the proposed paving on your property, including how it complies with the requirements shown on the Front Yard Landscaping Requirements on Single-Family Lots handout. Lastly, bring your plan to the Planning Division for review, and, if the zoning standards and requirements are met, a Zoning Clearance is issued.

Would you like to modify the landscaped parkway in front of your home?

First, refer to the Front Yard Landscaping Requirements on Single-Family Lots exhibit to determine if what you want to do meets City standards. A parkway is the area between the public sidewalk and the street and is required to be landscaped. This area is included in the calculation of the minimum required front yard landscaping.

Contact the Public Works Department at (805) 583-6786 for issues regarding trees within the street parkway. Decorative pavers may be used in the parkway if they are integrated with the landscape design, as approved by the Deputy Director/City Planner.

Monolithic concrete paving may not be used in the parkway except as part of a driveway. Artificial turf may be used in the parkway, with an Encroachment Permit from Public Works.

We recommend you visit the Planning Division, where a Planner will assist you with your options based on your individual property. If you have any questions, please contact us at (805) 583-6769 or enviroservices@simivalley.org.

Are you considering adding an Accessory Dwelling Unit (ADU) to your residential lot?

The City passed an Ordinance in July 2023, updating the Development Standards for ADUs, to meet recent State Law changes. Download the City’s ADU Guide to learn more about the development standards for ADUs and Junior ADUs and how to start permitting your ADU. You can contact the Planning Division at (805) 583-6769 for further information.

Would you like to add a free-standing, non-habitable accessory structure to your property, such as a gazebo, shed, carport, or garage?

First, ensure the location of the proposed structure meets the City’s standards for height and setbacks from your property lines and other structures by reviewing Sample Plot Plan and Minimum Setbacks. Certain types of accessory structures may also have special design standards, which are described in the Simi Valley Residential Design Guidelines for Accessory Structure exhibit.

Before you proceed, we recommend that you visit the Planning Division for a preliminary review of what you would like to do. We can let you know your parameters based on your individual property, such as setbacks, height, special conditions, and any additional circumstances to consider before you proceed. If you have any questions, please contact us at (805) 583-6769 or enviroservices@simivalley.org.

Once you know your parameters, you or your contractor/architect will need to prepare the plot plan and building elevations. Submittal requirements and sample plans can be found on the City’s Sample Plot Plan and Minimum Setbacks and Residential Addition Submittal Requirements links.

When your plans are ready, you will need to bring them in to the Planning Counter, where a Planner will review them to make sure the City standards are met. If they are, Planning will issue you a Zoning Clearance so that you may proceed to the next step.

If your accessory structure is more than 120 square feet in size, you will need to obtain a Building Permit. The specific submittal and permit requirements, including the application can be found at Building & Safety Division, or you may also contact the Building Permit Counter at (805) 583-6723 or enviroservices@simivalley.org for more information.
