What changes a site plan in Arizona
Arizona sets five conditions of its own on a site plan. Water and the seal rule come first; the review clock and Prop 207 shape how the application is filed.
Water comes before layout in the Phoenix AMA. Since June 2023, ADWR has stopped approving new groundwater-based assured water supply determinations [4]. A subdivision in an Active Management Area needs a Certificate of Assured Water Supply or service from a designated provider, and ADWR has designated 15 municipal providers in the Phoenix AMA, including all large cities [4]. Which side of a designated provider's boundary the parcel sits on is the first fact the concept records.
Assets that are not subdivided for sale sit outside that gate. Commercial, multifamily rental and RV assets that do not subdivide lots for sale are outside the subdivision CAWS requirement [4]. Designated providers may continue to serve new uses such as apartments [4]. The same parcel can be closed to a for-sale subdivision and open to a rental, RV or commercial program.
The word "preliminary" on the sheet is a legal line. Under the Board of Technical Registration's rule, a registrant must seal before submitting to "any regulatory or review body," "unless the document is marked 'preliminary,' 'draft,' or 'not for construction'" (A.A.C. R4-30-304(D)) [1]. Sealed documents carry the seal and signature on each drawing sheet, the specification cover, reports and letters (R4-30-304(A)) [1]. A concept site plan that carries the marking goes in unsealed; the sealed set follows from the registrants of record.
Staff, not a hearing, approves the site plan. HB 2447, enacted as Laws 2025, Ch. 31 and signed March 31, 2025, changed A.R.S. 9-500.49 from "may" to "shall," so cities must authorize staff approval of site plans and plats "without a public hearing," effective from and after December 31, 2025 [6]. During substantive review under A.R.S. 9-835, a municipality "may make one comprehensive written or electronic request for corrections" [5], and a municipality that misses the overall time frame refunds the fees charged [5, 7]. A complete first submittal is the way to stay inside the posted time frame.
Prop 207 travels with every rezoning. A.R.S. 12-1134 gives just compensation when a post-acquisition land use law reduces fair market value, with a 90-day written demand and a three-year filing limit [8]. Cities routinely require A.R.S. 12-1134(I) waivers with rezonings, as Eloy's waiver form shows [9].
Approval layers: state, county and city
| Layer | Who acts | What it decides for a site plan |
|---|---|---|
| State | ADWR; ADEQ; the Department of Health Services through county health departments; the Board of Technical Registration; the Legislature | Assured water supply for subdivisions in AMAs [4]; construction stormwater and Aquifer Protection Permits [3, 10]; RV park and campground rules [11]; seals and the preliminary marking [1] |
| County | Board of supervisors, planning and zoning commission, county health, air quality district | In Pinal County, CI-2 uses listed in PCDSC 2.110 need an Industrial Use Permit: the Commission recommends, the Board of Supervisors decides, and copies go to the county engineer, health department and the Pinal-Gila County Air Quality Control District [12]; in Mohave County, the Board of Supervisors grants SUPs after a P&Z Commission recommendation [13] |
| City | Council, planning commission, staff | Staff approval of site plans and plats under A.R.S. 9-500.49 [6]; in Phoenix, a pre-application conference, preliminary review and final approval under ZO Sec. 507(D) [14] |
Health and access permits sit beside the land use decision. Mohave County Environmental Health inspects parks under ADHS delegation and a county public accommodations ordinance, at least annually [15]. A driveway or any work in state right-of-way needs a permit from the ADOT district office [16]. Military airports add a review of their own: in MCP2023010, a Buckeye-area site "within the 65 Ldn area" was limited to "only what is approvable by Luke Air Force Base (LAFB)" [17].
Who prepares and seals what
| Deliverable | Prepared by | Seal | Rule |
|---|---|---|---|
| Preliminary site plan: layout, pads, drives, parking, yield, site data table | Site planning studio | None, when marked "preliminary," "draft" or "not for construction" [1] | A.A.C. R4-30-304(D) |
| "A one or two story building or structure" up to 3,000 sq ft, not for more than 20 persons continuously, spans of 20 ft or less unless engineered trusses are used | A nonregistrant may design it [2] | None | A.R.S. 32-144(A)(4) |
| Detached single-family dwelling; water or wastewater work up to $12,500 | A nonregistrant may design it [2] | None | A.R.S. 32-144(A) |
| Sealed documents | Registrant | Seal and signature on each drawing sheet, specification cover, reports and letters [1] | R4-30-304(A) |
| Buckeye rezoning legal description and exhibit | Arizona registrant | Sealed [18] | Local practice |
| Buckeye civil, grading, drainage and building plans | Arizona-registered engineer or architect | Sealed; concept site plans at the zoning stage are not sealed [18] | Local practice |
| ADU plan sets for a city's pre-approved catalog | Any applicant: a municipality "may not restrict who may submit" [19] | Not stated | A.R.S. 9-461.19 |
The marking rule is what lets a developer show a full layout to a city before engineering starts. The engineer and architect of record then seal the civil and building sets on the same base, and the grading, drainage, water and wastewater design stays with them. Read who prepares a site plan for the roles in sequence, do I need an architect for a site plan for the licensing question, and the site plan architect page for the studio's side of it.
Statewide overlays
| Overlay | Rule | What appears on the plan |
|---|---|---|
| Construction stormwater | AZPDES CGP AZG2025-001, effective August 29, 2025, expiring August 28, 2030, for construction disturbing "1 or more acres" or part of a common plan, with a discharge to a WOTUS or MS4 [3, 20] | Disturbed acreage |

Jurisdictions with code-cited rules
These five jurisdictions have their rules documented down to the code section or the meeting record. The Phoenix metro page and the model projects for a snowbird RV park in Mohave County, an outdoor storage yard in Pinal County and an industrial outdoor storage yard in Buckeye carry the site-level detail.
| Jurisdiction | Process and code | What shapes the plan |
|---|---|---|
| City of Phoenix | Pre-application conference, preliminary review, final approval (ZO Sec. 507(D)) [14] | Fees charged after the second resubmittal; preliminary documents valid 24 months, plus 12 months in phased projects with partial final approval [14]; site analysis with the preliminary site plan in applicable areas [28] |
| Pinal County | Rezoning under PCDSC Ch. 2.166 [29]; Industrial Use Permit under PCDSC 2.110, which can run concurrently with rezoning [12] | Outdoor storage only as an accessory to an established primary use, "totally screened from view" and "Not to exceed 6 feet in height" (PCDSC 2.185.020, 2.185.100) [30] |
| City of Casa Grande | CGMC 17.58.030 [31] | Stored materials inside a fully opaque wall or fence at least six feet tall; no storage in the street-side half of a front or street-side setback, or in an interior side or rear setback [31] |
| Mohave County | Zoning ordinance adopted Nov 2, 2015, revised through Aug 3, 2026 [13]; RV Park Plan under Section 37.G, with a Petition of Exception (37.G.6) [32] | R-RV rezoning needs 2 contiguous acres (24.B.2) [13] |

Phoenix. A design review appeal carries the site plan, building elevations, context plan, landscaping and shading plan, and a 150 foot owner list, filed through ProjectDox [35]. Appendix A sets zoning fees, for example $36,555 base and $60,915 maximum for a nonregulatory specific plan [36]. Under ZO 702, the Planning and Development traffic engineer may grant up to a 15% parking reduction under the city's shared parking model [37].
Pinal County. Hearing officer fines in 2024 cases ran $750 per count for outside storage violations, or $2,250 for three counts [38]. At its February 20, 2025 meeting, the Planning and Zoning Commission approved PZ-016-24, a 2.84 acre GR to C-3 rezoning for Arizona Quality RV and Boat Storage, 7-0, and disapproved PZ-017-24, a 160-acre GR to I-3 solar rezoning, 5-2, after asking the applicant to consider "a 6' CMU wall around the entire facility" [39].
Mohave County. RV parks are allowed by right in C-RE (17.C.3), C-2H (30.C.4) and R-RV with an approved RV Park Plan (24.B.1.b), and by SUP in A, A-R, R-E, R-M, C-1, C-2, R-MH with a manufactured home park, and A-D [13]. Concept review is mandatory for a PAD (26.C.1), fees are set by Board resolution (Section 7), and a PAD of 80 acres or more needs a community meeting with notice to owners within one-half mile, at least four weeks before the P&Z hearing (26.C.2, 26.C.3) [13]. The first final plat or site plan is due within 2 years of PAD approval (26.D.6) [13].
Asset registries
| Asset | State rule | Numbers that shape the plan | Local layer |
|---|---|---|---|
| RV parks | Department of Health Services rules, A.A.C. R9-8, Article 5, enforced through county health departments; the responsible party's duties cover bathrooms per number of dependent RVs, water and sewage [11] | Coconino County caps density at 12 per acre unless the Board of Supervisors approves a master plan, with 10 ft separation and 10 ft from property lines [40]; above 100 spaces, 1 additional toilet and lavatory per sex per 30 spaces and 1 additional shower per sex per 40 spaces [41] | Town of Parker: CUP in R-3, 20 spaces per net acre, 1,250 sq ft and 30 ft wide spaces, 5 ft between RVs including awnings, no park models, stays limited to 180 days per year [42]; Apache County requires a CUP for any RV park [43]; Eloy requires one 9 x 20 ft visitor space per 8 RV spaces [44] |
| RV parks, Mohave County | County rules under ADHS delegation [15] | A dependent park model may be a permanent residence in an RV park (37.K.3.a) [45]; an RV subdivision lot is at least 2,500 sq ft, with enclosed accessory space up to the greater of 250 sq ft or 10 percent of the lot (37.K.4) [46] | RV Park Plan approved by the Director (37.G) [32] |
| Campgrounds | A.A.C. R9-8, Article 6: toilets and refuse (R9-8-607), camping shelters (R9-8-608) [11] | A stay of more than 180 days creates a "tenant" under A.R.S. 33-2102 [47] | Local zoning |
| Lodging | Lodging unit management at A.A.C. R9-8-1308 [11] | Short-term rental preemption reaches residential dwelling units only [26] | Local zoning |
| Car washes | Arizona commercial car washes need specific discharge permits (ADEQ P2 guidance) [48] | Not stated | Local zoning |
| RV and boat storage | Set locally | Maricopa County Z2020049 (Brown RV and Boat Storage SUP): 12 rows of canopy-covered RV and boat storage with about 192 spaces plus about 14 uncovered; hours Monday to Saturday 7 am to 5 pm [33] | Pinal County PZ-016-24 approved 7-0 [39] |
| Self storage | Set locally | Yardi Matrix put Phoenix's under-construction pipeline at 6.6% of stock in February 2026, against 2.4% nationally [49] | Local zoning |
| Industrial outdoor storage | ADEQ CGP and county dust rules [3, 24] | MCP2023010 rezoning recommended 7-0 [17]; Z2021137, an 11.7 acre Rural-43 to IND-2 IUPD rezoning, drew "No Concerns" from the City of Buckeye [50] | Pinal and Casa Grande screening rules [30, 31] |
| Multifamily | Designated providers may serve new apartments [4] | Phoenix ZO 702: up to a 15% shared parking reduction [37] | Local zoning |
| Assisted living | Department of Health Services, Bureau of Residential Facilities Licensing; A.A.C. Title 9, Ch. 10, Art. 8; A.R.S. 36-411 (NCAL 2023 edition) [51] | Building rules vary by size [51] | Local zoning |
| ADUs | ARS 9-461.18 (HB 2720, Laws 2024 ch. 196; local deadline Jan 1, 2025) [27] | Municipalities over 75,000: one attached and one detached ADU as a permitted use; 75% of house GFA or 1,000 sq ft, whichever is less; rear or side setbacks capped at 5 ft; no parking or in-lieu fees [27] | Phoenix: two ADUs per detached lot, a third in some cases [52]; max 15 ft height in required rear or side yards without a use permit [53]; plot or site plan with site planning approval before the residential submittal [54] |
Arizona's ADU statute also bars fire sprinkler or commercial-code requirements for ADUs (9-461.18(D)) and bars building on public utility easements without the utility's consent (9-461.18(E)) [27]. Phoenix's standard plan library makes the point for pre-approved designs: "A plot/site plan will still be required for permitting" [55].
Two pages go deeper on Arizona assets: RV park site plans in Arizona and industrial outdoor storage site plans in Arizona. Layout standards by asset, across states, sit on the pages for RV parks, campgrounds, RV and boat storage, self storage, car washes, industrial sites and flex space.
Law changes and shot clocks
| Change | What it does | Date |
|---|---|---|
| HB 2447 (Laws 2025, Ch. 31) | A.R.S. 9-500.49 from "may" to "shall": staff approval of site plans and plats "without a public hearing" [6] | Signed March 31, 2025; effective from and after December 31, 2025 [6] |
| SB 1353 (Laws 2025, Ch. 187) | Applies when a municipality fails to act on a single-family residential building permit "within fifteen working days"; the municipality keeps a list of "at least three third-party reviewers"; amends A.R.S. 9-835 [56] | Signed May 13, 2025 [56] |
| SB 1611, Ag-to-Urban (Laws 2025, Ch. 252) | IGFR holders in the Phoenix and Pinal AMAs may relinquish their rights for Groundwater Savings Credits usable toward physical availability [25] | Effective September 26, 2025; 2026 amendments effective September 12, 2026 [25] |
| ADAWS rule | Alternative Designation of Assured Water Supply [57] | Effective November 25, 2024 [57] |
| AZPDES CGP AZG2025-001 | Construction stormwater coverage; new NOI and fee required [3] | Effective August 29, 2025 [3] |
| SB 1529 (Laws 2025, ch. 259) | Class 4 ADU plans at 200, 600 and 1,000 sq ft, three elevation options per class; administrative approval without discretionary review [19] | From July 1, 2026; Class 2 and 3 duplex and triplex plans at 400 to 1,000 sq ft per unit from Jan 1, 2027 [19] |
A.R.S. 9-835 sets the clock for municipal licenses, including site plans:
- Municipalities must post an overall time frame stating the administrative completeness and substantive review periods separately [5, 58].
- If no completeness or deficiency notice issues within the administrative period, the application "is deemed administratively complete" [5].
- Substantive review allows one comprehensive written or electronic request for corrections [5].
- If the overall time frame or an agreed extension is missed, the municipality refunds the fees charged [5, 7].
- The section does not apply to a license issued within seven working days (9-835(O)) [59].
A city that posts a pre-approved ADU plan must remove it within 30 days on request [19].
Climate and site factors
Water availability, not soil or slope, is the gating site factor in the Phoenix and Pinal AMAs, and it is settled by provider and certificate rather than by grading. Dust is the second statewide site factor: Pinal County's permit starts at 0.1 acre of development activity [22], and Maricopa County's Rule 310 permit at 0.10 acre of disturbance [24].
Mohave County shows how terrain and lighting enter the plan. RVs in a Special Flood Hazard Area must comply with the Mohave County Flood Control Ordinance (37.K.2.f) [46]. In a PAD, buildings on slopes over 20 percent get an extra downhill story (26.E.3), and cluster open space prioritizes slopes over 25 percent (12.1.D.1) [13]. Section 38, Outdoor Light Control, sets the county's dark-sky rule [13].
Freeway frontage is a visibility factor in the West Valley. In MCP2023010, the City of Buckeye "prefers a solid wall be placed along the freeway to screen the property so those traveling along the freeway don't see the outdoor storage use" [17].
Proof points
- EPCOR West Valley designation. EPCOR received AWS No. 2025-02 for its West Valley System on October 7, 2025, which ADWR called "the first 100-year Assured Water Supply designation in the Phoenix Active Management Area in 25 years," covering "enough water for 60,000 new homes" [60, 61].
- Forestar Group, Buckeye. The first Ag-to-Urban approval, with credits for 825 homes [62, 63].
- Maricopa County Z2020049. The Commission recommended the Brown RV and Boat Storage SUP 9-0 on December 9, 2022, and the Board of Supervisors report followed on January 25, 2023 [33].
- MCP2023010, Buckeye area. Over the City of Buckeye's opposition, the County Planning and Zoning Commission recommended approval of an outdoor storage yard rezoning with conditions 'a' to 'i' on October 24, 2024, by 7-0 [17].
- Pinal County, February 20, 2025. PZ-016-24, a 2.84 acre RV and boat storage rezoning, approved 7-0 [39].
- Permit volume. The Phoenix metro permitted 45,884 units in 2024, the fourth-largest permit market; the City of Phoenix permitted 8,997 units in 2024, down from 14,468 [64]. Population grew from 4,851,295 (2020 base) to 5,228,938 (2025), +377,643 or about 7.8%, and Maricopa County reached 4,689,558 in 2025 [65].
What the preliminary plan carries in Arizona
An Arizona preliminary site plan from the studio is a real first draft that goes to the city or county unsealed, so it travels under the Board's "preliminary" marking. It places the buildings, floor plans, internal roads, drive aisles, parking, pads and units, and its site data table counts the yield against the rules above: disturbed acreage against the 1 acre stormwater line and the 0.1 acre dust line, the water provider position for any lot to be sold, the screening and setback rules for outdoor storage, and for a park, the county density and fixture counts.
What it leaves out is the engineering: grading, drainage, water, wastewater and stormwater design belong to the client's engineer of record, who seals that work on top of the plan. In the meantime the plan serves the pre-application conference, the lender's file and the general contractor's first price. For the step from draft to sealed set, read preliminary versus final site plans; for scope and process, the site plan consultant and site plan services pages. Market background: Phoenix multifamily, Q3 2025 and industrial outdoor storage development.
Neighboring states with their own pages are California, Nevada, Utah and New Mexico. Every covered state appears on the service areas index.
Frequently asked questions
Can I submit an unsealed site plan in Arizona?
Yes, if it is marked "preliminary," "draft," or "not for construction" (A.A.C. R4-30-304(D)). A registrant otherwise seals before submitting to any regulatory or review body [1].
Can a non-architect design a small commercial building in Arizona?
Yes: a one or two story building of up to 3,000 sq ft, for not more than 20 persons continuously, with spans of 20 ft or less unless engineered trusses are used (A.R.S. 32-144(A)(4)) [2].
When do I need ADEQ construction stormwater coverage?
At 1 acre or more of disturbance, or as part of a common plan, with a discharge to a WOTUS or MS4, under AZPDES CGP AZG2025-001. A new NOI and fee are required under that permit [3].
Can I subdivide in the Phoenix AMA on groundwater?
Not with a new groundwater-based certificate: since June 2023, ADWR has stopped approving new groundwater-based assured water supply determinations. Designated providers may continue to serve new uses such as apartments [4].
Does a package wastewater plant need an Aquifer Protection Permit?
Yes. Sewage treatment facilities are discharging facilities under A.R.S. 49-241(B)(9) [10].
What if a city misses its review time frame?
How long do I have to file a Prop 207 claim?
Three years (A.R.S. 12-1134(G)), after a 90-day written demand (12-1134(E)) [8].
What setback can an Arizona city require for an ADU?
No more than 5 ft rear or side in cities over 75,000 (ARS 9-461.18(B)(6)) [27].
How long is a Phoenix preliminary approval valid?
24 months under Zoning Ordinance Sec. 507, with an extra 12 months in phased projects that have partial final approval [14].
