Maricopa Assessor's GIS Data
You will need your parcel number. We could not pull up a parcel map on this site with only the address of the property in question. The site will also prompt you to install an AUTODESK MAPGUIDE ACTIVE X CONTROL in order to view maps online. We were able to install the control quickly with no glitches.
Contact the Maricopa County Assessor's Office if you do not have your parcel number. You can enter this number into the form on their site to access your map.
If your parcel map indicates that your fence will be close to the property line, it is best to hire a surveyor to map out the actual boundary accurately.
The GIS dept of the assessor’s office told us the following:
"We cannot provide advice on locating fences on a property, but can suggest that you contact the City of Phoenix, who should have information regarding setback limits and building regulations. The Assessor's maps are not survey accurate and should just be used as a reference in locating your property. You can hire a surveyor to get an accurate representation of your property and/or contact a fence company to see if they are aware of any regulations that may need to be adhered to."
