General Additions, including Screened Porches
Before beginning construction on an addition to your home, there are several steps you will need to take to make sure your addition will be in compliance with local regulations regarding land and construction. Your proposed addition must meet zoning setback and yard requirements. If your home is a landmark, next to a landmark, or in an historic district, changes to it may require special review. Also in older houses, an addition may require electrical, heating and plumbing systems to be upgraded.
Process Overview
Determine Zoning
Before developing a parcel of land, you will need to determine if the parcel is zoned for your desired use or if there are any special development considerations for your project.
Zoning will be able to tell you the zoning of the property or if there are any special considerations for your project. If your project requires special handling, our staff will inform you of the requirements and next steps.
Find out the zoning for your property.
Who to Contact
Zoning at Building Permits: (608) 266-4551.
Draw a Plan
Consider these points when planning your addition:
Use
- City codes allow additions for almost any type of single family use. However, adding a second dwelling unit to a single family home is permitted only under certain circumstances.
- Additions solely for a home occupation (home-based business) are not allowed. Home occupations are subject to special requirements. Ask Zoning staff about these requirements.
Placement
- Houses and additions must be set back from all lot lines. This setback distance is determined by how your property is zoned. If the depth of your house from front to back is large, you may be required to increase the side yard setbacks. Again, Zoning staff will advise you if a special review and approval is needed.
With these requirements in mind, you need to make a drawing (site plan) of your entire property with the location of the addition to show to Zoning staff. Follow the example plan provided, and draw a plan to scale. Using a scale of 1″=20′ usually works best. Show the measurements of the lot, house, addition and any other structures. Also show the distances from the house and addition to the lot lines.
Review Plans
Be sure to meet with Zoning staff at least a month or more before you apply for your construction permits. This will help you avoid delays when you want to start construction. Some types of additions need special review by a board or commission. These reviews usually require a fee and can add weeks to the review and approval process. Zoning staff will look at your plan and tell you if a special review is needed.
