Phoenix Affordable Unit Percentage Rules - Municipal Code

Land Use and Zoning Arizona 4 Minutes Read · published February 05, 2026 Flag of Arizona · By Emily Carter

Phoenix, Arizona developers and planners must determine whether proposed projects trigger affordable-unit requirements under the city code or enacted housing agreements. Start by confirming the project zoning, applicable overlays, and any affordable housing incentives or conditions tied to rezoning or permits [1]. For implementation details and program guidance contact the Planning & Development Department or Housing Department for project-specific determinations [2][3].

Check zoning maps and recorded development agreements before applying calculations.

How required affordable percentages are established

Phoenix typically implements affordable-unit obligations through specific zoning approvals, development agreements, or incentive programs rather than a single citywide inclusionary percentage in one consolidated section of the municipal code. To calculate a required percentage for a specific project, follow the controlling instrument (rezoning condition, development agreement, or incentive program) that specifies:

  • Base unit count to which the requirement applies (for example, total dwelling units proposed).
  • Effective dates and phasing that may alter the numerator or denominator over time.
  • Any fee-in-lieu options, required affordability period, and target income bands (AMI levels).

Common calculation methods:

  • Percentage of total units: required units = total units × required percentage (rounding rules set by the governing instrument).
  • Phased projects: apply percentage to each phase or to the final cumulative unit count as specified.
  • Fee-in-lieu conversions: the governing instrument should state the per-unit fee or formula; if not, the fee is not specified on the cited page.

Penalties & Enforcement

Enforcement authority usually lies with the Planning & Development Department and the Housing Department when a recorded development agreement or permit condition contains affordable-unit obligations. Specific monetary fines, escalation, and statutory penalties vary by instrument; when a code section or agreement lists fines, follow that amount. If a municipal-code page or program page does not state fines, the amount is not specified on the cited page [1].

  • Enforcer: Planning & Development Department and Housing Department; complaints and compliance inquiries are submitted via the departments' official contact pages [2][3].
  • Fine amounts: not specified on the cited page where a specific development agreement or ordinance is not published.
  • Escalation: first, repeat, and continuing-offence provisions depend on the controlling ordinance or agreement and are not specified on the cited page if absent.
  • Non-monetary sanctions: stop-work orders, injunctions, requirements to perform the obligation or record corrective instruments, and referral to municipal court are possible remedies under development agreements or permit conditions.
  • Inspection and complaint pathway: file compliance questions or complaints with Planning & Development or Housing via their official pages [2][3].
  • Appeals and review: appeal routes generally follow permit and zoning appeal procedures set by the municipal code or the development agreement; time limits for appeals depend on the specific ordinance or notice and may be set in the governing instrument or administrative rules.
If a specific fine or deadline is absent from the public page, it will be listed in the recorded agreement or ordinance for the property.

Applications & Forms

The city publishes permit and rezoning application forms through Planning & Development; specific affordable-housing agreement templates or fee-in-lieu payment forms may be part of a development agreement record or housing program materials. If a named application or form is not on the cited program pages, it is not specified on the cited page [2][3].

How-To

  1. Confirm which governing instrument controls the project (zoning case, development agreement, or incentive program).
  2. Identify the base unit count and any phasing rules before applying a percentage.
  3. Apply the required percentage to the applicable unit base; follow rounding and counting rules in the instrument.
  4. If a fee-in-lieu is allowed, use the formula or per-unit fee in the agreement; if none is listed, state that the fee is not specified on the cited page.
  5. Record required covenants, notify the Housing Department if required, and obtain final compliance sign-off before certificate of occupancy issuance.
Always confirm calculations against the recorded agreement and seek official confirmation from Planning & Development or Housing.

FAQ

How do I know if my project must include affordable units?
The controlling rezoning, development agreement, or incentive program will state any affordable-unit requirement; check project conditions and consult Planning & Development [2].
Where can I find the municipal code language?
Consult the City of Phoenix municipal code online for zoning and procedural provisions and review any recorded development agreements for parcel-specific obligations [1].
Can I pay a fee instead of building units?
Some instruments allow fee-in-lieu; the option and fee formula must be stated in the governing instrument or housing program materials, otherwise it is not specified on the cited page [3].

Key Takeaways

  • Affordable requirements are set by the specific controlling instrument, not by a single universal percentage.
  • Calculate using the base unit count and follow rounding, phasing, and affordability period rules stated in the instrument.
