The Neighborhood Preservation Ordinance (NPO) is Chapter 39 of the Phoenix City Code. It was established to prevent and address deterioration, blight and/or hazardous conditions that can negatively impact neighbor-hoods. It provides established mini-mum property maintenance standards for all structures and proper-ties in the City.

• Dispose of trash properly - Property owners are responsible for keeping their property free of junk, litter and debris. This includes tires, junk, furniture, building and landscaping material; litter such as discarded paper, cardboard, plastics, etc.; debris such as tree trimmings and fallen tree limbs; or any other discarded items.

• Park in designated areas - All parking and maneuvering areas must be dust proofed according to City specifications. 

• Remove visible outdoor storage - Outside storage of personal property at residentially zoned properties is limited to the rear yard behind the primary structure only.  Any building or landscaping materials for use on the property, machinery, appliances or parts/auto parts may not be visible from beyond the boundaries of a residentially zoned property.  Outdoor storage of items for commercial or business use at a residential property is not allowed. 

• Maintain fences - Fencing and screening walls must be structurally sound and made from the same materials.  They also must be maintained so that they are free from deterioration and blight.  Some examples include fences or walls that are leaning, missing slats or blocks, rotted or damaged.

• Remove inoperable vehicles - Inoperable vehicles must not be visible from beyond the bounds of the property.  An inoperable vehicle is one that is not equipped with all parts that are required to legally and safely operate on public streets and/or cannot be driven under its own power.  Car covers, tarps, bamboo, shades and other similar types of materials are not acceptable screening.

• Keep vacant buildings secure - Property owners are responsible for assuring all vacant buildings and structures (including primary structures, garages, storage structures, accessory buildings, sheds, etc) are secured so that windows, doors or other openings cannot be accessed from the outside.  A property owner may be required to board up a building/structure to City specifications if it becomes vacant and is not secure.  Boarding up a building\structure is a one time, temporary securement option, for a period not to exceed 180 days. Rehabilitation or demolition of a structure may be required under certain conditions.

• Maintain vegetation - Property owners are responsible for keeping their properties, and the adjacent rights  of way, free of dead or dried vegetation (weeds, tall grass, tumbleweeds, shrubs, trees, palm fronds, etc).  All dead or dried vegetation must be removed and disposed of properly.  Property owners are also responsible for assuring that grass and weeds on their property and in the adjacent rights of way do not exceed six inches in height.
