Permitting, Zoning, or Statutory Basis

In Scottsdale, Arizona, landlords must comply with local zoning regulations when converting residential properties into accessory dwelling units (ADUs) or duplexes. The primary statutory basis for these regulations is the Scottsdale Zoning Ordinance (SZO), which governs land use and development within the city.

ADU Regulations

To convert a residential property into an ADU, landlords must obtain a Building Permit from the City of Scottsdale. This process involves submitting an application and providing documentation that demonstrates compliance with zoning requirements, including the maximum allowable height for ADUs and adherence to setback distances from property lines.

Important Note: Landlords must also ensure that the ADU does not exceed 50% of the total floor area of the primary residence. This requirement is outlined in Section 15.2.4 of the SZO.

Duplex Conversion Regulations

Converting a single-family home into a duplex requires obtaining both a Building Permit and a Conditional Use Permit from the City of Scottsdale. The Conditional Use Permit is necessary because duplex conversions are considered a special use under the SZO.

Key Requirements:

  • Building Permit: The application must include detailed plans and specifications for the proposed conversion, including floor plans, elevations, and structural details.
  • Conditional Use Permit: This permit is required if the proposed conversion would significantly impact the neighborhood or require special conditions. The application must demonstrate that the conversion is in the public interest and will not cause undue hardship or disruption.

Important Note: Landlords must also ensure that the total floor area of the converted units does not exceed 10,000 square feet. This requirement is outlined in Section 15.2.4 of the SZO.

Off-Street Parking Requirements

Off-street parking is required for all residential units in Scottsdale, including ADUs and duplexes. The minimum number of parking spaces required is determined by the size of the primary residence and any additional units.

Key Requirements:

  • Primary Residence: The minimum number of parking spaces required for the primary residence is two (2). This requirement is outlined in Section 15.3.4 of the SZO.
  • ADU: The minimum number of parking spaces required for an ADU is one (1). This requirement is outlined in Section 15.3.4 of the SZO.
  • Duplex: The minimum number of parking spaces required for a duplex is three (3). This requirement is outlined in Section 15.3.4 of the SZO.

Important Note: Landlords must ensure that all parking spaces are accessible to residents and guests. This includes providing clear signage, maintaining the integrity of parking areas, and ensuring that no parking spaces are obstructed or reserved for non-residents.

Lease Clauses, Notice Periods, and Timing Requirements

When leasing an ADU or duplex in Scottsdale, landlords must include specific clauses in the lease agreement to ensure compliance with zoning regulations and address potential disputes.

Zoning Compliance Clause: The lease agreement should include a clause that confirms the landlord’s compliance with all zoning regulations, including obtaining necessary permits and ensuring adherence to parking requirements.

This clause should specify how many parking spaces are required and what happens if the tenant fails to provide or maintain the necessary parking spaces.

Timing Requirements

Important Note: Landlords must also ensure that all lease agreements are executed in accordance with the City of Scottsdale’s leasing regulations. This includes providing tenants with a copy of the lease agreement, disclosing any material facts about the property, and ensuring that the lease agreement is signed by both parties.
