Addressing and Suite Assignments

An existing address, including suite numbers, can be verified through the Property Information Request page. If an address cannot be found, it is not an official address in Scottsdale’s Land Information System and an address should be requested.

Start an addressing request: Download the Addressing Request Application and email the completed form with a site plan or floor plan.

Addressing Request Application

Submit an addressing request when a project requires any of the following:

• An address for a new home, commercial building or residential development
• Official suite numbers for a new commercial building
• A suite assignment or verification needed for a tenant-improvement permit or Certificate of Occupancy
• New suite numbers when an existing commercial space is divided
• Revised suite numbers when two or more commercial spaces are combined
• Correction of an unofficial, lettered or nonconforming commercial suite number
• An address associated with a lot split, lot tie or recorded plat
• A street number change resulting from a change in the building’s access or front-facing orientation
• A service-only address for equipment requiring electrical or water service

In most cases, submit the Addressing Request Application with the applicable permit application and plans. The request will be forwarded for addressing review as part of the permit process.

Address and suite issues must be resolved before inspections begin and before a Certificate of Occupancy can be issued. Submit the request early to avoid delays during plan review, inspection or occupancy approval.

Some undeveloped properties do not yet have an address that can be used to apply for a permit. For a new home, commercial building or residential development in this situation, GIS may assign the address separately as part of the plat and development process and before the plat is recorded with Maricopa County.

1. Complete the Addressing Request Application.
2. Include a site plan or floor plan that clearly shows the property, building, suites or equipment involved in the request.
3. Email the completed application and plans or include them with the applicable permit submittal.
4. Allow approximately 5–10 business days for processing. Processing time may vary based on request project complexity. Expedited review is not available

The city assigns all official commercial suite numbers. Property owners, leasing agents, architects, contractors, tenants and businesses should not independently create suite numbers.

Commercial suite assignments follow these standards:

• Commercial suites use three-digit numbers only; lettered designations such as Suite 100A are not permitted.
• First-floor suites are assigned in the 100 range, second-floor suites in the 200 range, third-floor suites in the 300 range, and so on.
• Suite numbers are generally assigned in increments of five, such as 100, 105, 110 and 115. This provides room for future suite divisions.
• Suites are numbered in a logical consecutive sequence without doubling back so they can be located quickly by emergency responders.
• A commercial building receives one street address. Individual tenant spaces within the building are identified by official suite numbers.

Tenant improvements and Certificates of Occupancy

A business taking over an existing commercial space requires city verification or assignment of its suite number when a permit or Certificate of Occupancy is required. A request is also required when the proposed suite number does not exist in city records or does not match the approved building layout.

Address or suite discrepancies must be resolved before a Certificate of Occupancy is issued.

Dividing or combining suites

Submit an addressing request when an existing suite will be divided into two or more tenant spaces or when multiple suites will be combined. Include a floor plan showing the existing and proposed layout. The city will assign or revise the suite numbers so the building retains a clear and consecutive numbering sequence.

New commercial buildings

A new commercial building must receive an official street address before permit processing can proceed. If the building will contain multiple tenant spaces, submit a floor plan so the city can assign the suites. Do not place suite numbers on plans, signs, leases or business materials until the assignments have been approved by the city.

New homes and residential developments must receive official addresses through the City. Apartment and condominium living spaces are designated as units and generally use four-digit numbers. First-floor units are assigned in the 1000 range, second-floor units in the 2000 range, and so on.

For undeveloped properties that do not yet have an address, GIS may assign addresses as part of the plat and development review process before the plat is recorded with Maricopa County.

Submit the Addressing Request Application and site plan with the applicable permit request for a lot split or lot tie. GIS reviews the site plan and assigns the resulting addresses before the plat or related document is recorded with Maricopa County.

Applicants should not select or advertise new addresses before GIS completes the official assignment.

A homeowner, property owner, builder or authorized agent may request a street number change. Requests may be considered when a home’s front-facing orientation or primary access changes. Submit the Addressing Request Application with the applicable architectural or site plans.

A preferred street number may be requested, but approval is not guaranteed. The property may need to be replatted before the requested number can be assigned. GIS reviews street-number requests, and the city may require an address change when necessary to improve emergency response or correct a nonconforming address.

After approval, the property owner is responsible for updating on-site numbers, mail, utilities, licenses and other business or personal records. The city will notify Maricopa County of the official change.

Equipment that requires electrical or water service may need a service-only, or non-system, address. Examples include landscape meters, electrical pedestals, traffic signals, electric gates, cell sites, well sites and public restrooms.

Submit the Addressing Request Application with a site plan showing the equipment’s exact location.

Important: A non-system address is an administrative service identifier. It is not a valid premises or mailing address, will not appear in public mapping applications and cannot be selected as a project address when applying for permits.

The city applies regional and Scottsdale addressing standards to create predictable address sequences and help emergency responders locate properties and tenant spaces quickly.

• Addresses are based primarily on the street from which emergency responders would access the property.
• On east–west streets, even numbers are assigned on the north side and odd numbers on the south side.
• On north–south streets, even numbers are assigned on the west side and odd numbers on the east side.
• Buildings, suites and units are arranged in a logical sequence that avoids double-back numbering.

Addressing decisions are based on public safety, access and the surrounding approved address range. Requested addresses or suite numbers are not guaranteed.

• Use only addresses and suite numbers officially assigned by the city.
• Make sure the site plan or floor plan clearly identifies the space, property or equipment involved.
• Include an active permit or plan-check number when one has already been created.
• Allow enough time to resolve addressing before inspections and Certificate of Occupancy review.
