Where We Work

Phoenix Architect — Custom Homes, Additions, Infill & Multifamily

Phoenix is where E-Project's residential and multifamily capability overlap most: custom homes and additions alongside townhomes, condominiums and subdivision work. It is also the jurisdiction where knowing which expedited program applies is worth real money.

The short answer

For a detached house in Phoenix, the fast track is Priority Expedited Plan Review — not Self-Certification, which excludes detached single-family building plans. PEPR costs three times the base plan review fee and halves the published review goal. If the parcel is hillside, neither program is available and Section 710 caps lot coverage at 25%.

Calendar days, initial review. The City republishes this monthly and advises planning around the longer of goal and actual — worth noting that both remodel and addition categories were running over goal.

Priority Expedited Plan Review

  • Eligibility includes non-hillside single family residences when resources are available.
  • Fee: three times the base amount for the plan type; +20% of the expedited fee if a third review is needed.
  • Review time: one-half of the published goal, with prorated refunds possible if the City misses it.
  • PDD may deny expedited status when staff resources are insufficient.

Self-Certification — what it really covers

The program has run since 2010 and lets registered professionals certify code compliance in place of traditional City review. But detached single-family building plans are not eligible. Residential reach is single-family subdivisions up to 160 acres for grading and drainage civil plans, plus multifamily and other buildings.

  • Certifying professional: architect or structural engineer registered in Arizona at least three years, City training completed, renewed every three years.
  • Ineligible: hillside development areas, FEMA special floodplain hazard areas, new high-rises, extra-large assembly, hazardous occupancies.
  • Automatic audit thresholds: remodels 25,000+ SF, shell buildings 25,000+ SF, new buildings 10,000+ SF.
  • City states permits can be issued within one to five business days for eligible projects.

Frequently Asked Questions

Can my house plans be self-certified in Phoenix?

Not for a detached single-family house. The City of Phoenix Self-Certification program excludes detached single-family residential from building plan eligibility; its residential reach is single-family subdivisions up to 160 acres for grading and drainage civil plans, plus multifamily and other building types. To certify building plans the professional must be an architect or structural engineer registered in Arizona for at least three years with City training completed. For a house, the applicable fast track is Priority Expedited Plan Review.

What is Priority Expedited Plan Review and is it worth it?

PEPR is the City of Phoenix expedited path whose eligibility explicitly includes non-hillside single family residences when resources are available. The fee is three times the base amount for the plan type, and review time is one-half of the published goal for that plan type, with prorated refunds possible if the City misses the deadline. Whether it is worth it depends on your carrying cost — halving a 30-day goal to 15 days on a custom home is meaningful if a construction loan is running. PDD may deny expedited status when staff resources are insufficient.

How long does Phoenix residential plan review actually take?

The City publishes a monthly turnaround report. In the July 2026 edition: custom and standard plans goal 30 calendar days with actual average 30; major remodels and additions goal 30 with actual average 37; minor remodels and additions goal 20 with actual average 24; plot plans goal 5 with actual average 2. The City recommends planning around the longer of goal and actual, and both remodel and addition categories were running over goal.

Does hillside status affect a Phoenix project?

Substantially. Phoenix Zoning Ordinance Section 710 applies where natural terrain on any lot or portion of a lot has a slope of 10 percent or greater, in all zoning districts. It caps lot coverage at 25 percent where slopes exceed 10 percent, sets a minimum 18,000 square foot lot with 120-foot width and depth for standard single-family, limits density by slope band, and requires a slope analysis and density study before rezoning, preliminary site plan or building permit. Hillside status also disqualifies a project from both Self-Certification and Priority Expedited Plan Review.

What are the setbacks and lot coverage for a Phoenix R1-6 lot?

Under the standard option in Table 613.1, R1-6 requires a minimum 60-foot lot width and 94-foot depth, with front setback 20 feet, rear 25 feet, street side 10 feet and interior sides 10 feet and 3 feet. Height is limited to two storeys and 30 feet. Lot coverage is 50 percent, plus an additional 10 percent for an accessory dwelling unit and/or attached shade structures, for a total of 60 percent. Other districts vary and should be confirmed against the applicable district table.
