Find Arizona Land Disturbance, Grading & Sitework Permit Records
An Arizona land disturbance permit search usually requires more than one database. Grading and site-development approvals are commonly issued by a city or county, while larger construction sites may also need Arizona Department of Environmental Quality stormwater coverage, local dust-control authorization, floodplain approval, or another site-specific permit.
Use this guide to identify the correct authority, search existing records, understand common thresholds, and check the approvals that may apply before clearing, grading, excavating, stockpiling soil or changing drainage.
Where Should an Arizona Land Disturbance Permit Search Start?
Start by identifying the jurisdiction responsible for the parcel. A Phoenix property, a parcel in unincorporated Maricopa County, a Tucson site and land in unincorporated Pima County can follow different grading, drainage and permit procedures even though all are in Arizona.
Do not assume the county issues the construction permit simply because the parcel is located inside that county. Incorporated cities normally administer their own development codes and permit systems, while county departments generally handle development in unincorporated areas.
Which Approvals Can Apply to Arizona Sitework?
“Land disturbance” is a useful search phrase, but Arizona agencies often use more specific terms such as grading, drainage, clearing, excavation, paving, stockpiling, development package, stormwater construction permit, dust control or floodplain use permit.
| Approval | Typical trigger | Authority to check |
|---|---|---|
| Grading / site development | Cut, fill, clearing, earthwork, drainage changes, stockpiles, paving or site preparation. | City or county planning, development or engineering department. |
| Construction stormwater | Covered construction activity involving significant land disturbance and qualifying stormwater discharge conditions. | Arizona Department of Environmental Quality. |
| Dust control | Dust-generating soil disturbance above local air-quality thresholds. | Applicable county or local air-quality agency. |
| Floodplain use | Grading, structures or other development within a regulated floodplain or floodway. | Local flood-control district or floodplain administrator. |
| Right-of-way / access | Driveways, utilities, excavation or construction affecting a public road or right-of-way. | City, county or transportation agency. |
| State Trust Land authorization | Ground-disturbing activity or improvements on Arizona State Trust Land. | Arizona State Land Department. |
A single development can require several of these approvals. A grading permit from a city, for example, does not automatically replace a separate ADEQ stormwater authorization or local dust-control permit.
ADEQ Construction General Permit Rules for Land Disturbance
ADEQ administers the Arizona Pollutant Discharge Elimination System Construction Activity General Permit, commonly called the CGP. The current 2025 CGP, permit number AZG2025-001, became effective August 29, 2025 and replaced the previous construction general permit.
ADEQ states that CGP coverage applies to construction activities disturbing one acre or more when the applicable discharge conditions are met. A project disturbing less than one acre can also fall within the program when it is part of a larger common plan of development or sale that will ultimately disturb one acre or more.
One-acre threshold
Do not calculate only the building footprint. Consider the area disturbed by clearing, grading, excavation, material storage, access, staging and other construction activity that forms part of the covered project.
Smaller lots can still qualify
A lot under one acre may still be associated with a larger development or sale plan whose total disturbance meets the program threshold.
Prepare the SWPPP
ADEQ instructs operators to complete the Stormwater Pollution Prevention Plan before submitting a Notice of Intent for CGP coverage.
Use the current fee schedule
ADEQ’s construction general permit fees are acreage-based and are subject to periodic adjustment. Verify the current fiscal-year fee rather than relying on an older project estimate.
How to search the ADEQ construction permit database
The public construction stormwater search allows users to search using identifiers such as the LTF number, company name, facility name or county. If you know the project name but not the permit number, try a shortened project or company name and compare the location carefully.
Arizona Grading Requirements Vary by City and County
Local rules can be substantially more specific than the statewide stormwater threshold. The examples below show why property location and project scope must be checked before sitework starts.
| Jurisdiction | What the official guidance says | Best record/search route |
|---|---|---|
| City of Phoenix | Phoenix requires grading and drainage plan review for residential and nonresidential construction projects. Civil/site work can include grading, drainage, erosion, retention, paving and stormwater elements. | Phoenix PDD Permit Information Search |
| Unincorporated Maricopa County | County permitting services list clearing and grading, grading, paving, stormwater and related land-use permits. Additional flood-control or air-quality approvals can apply. | Maricopa County Permitting Services |
| Unincorporated Pima County | Pima County identifies Type I and Type II grading permit categories, with thresholds based on factors such as graded area, project type, stockpiling and slope conditions. | Pima County public permit search |
| City of Tucson | Tucson development packages can include grading, paving, stormwater pollution prevention, floodplain review and other site-development elements. | Tucson Property Research Online |
Pima County examples
Pima County lists a Type I grading permit for several situations, including a single-dwelling residential development on one lot with a graded area of 14,000 square feet or more, qualifying nonresidential development, certain stockpiles, grading on slopes of 15% or greater, and more than 3,000 square feet of new pavement.
Type II grading permits apply to development requiring a subdivision plat or development plan and to stockpiling above the county’s stated Type I range. Because exemptions and additional department reviews also exist, use Pima County’s current grading guidance rather than treating one threshold as a complete permit test.
Tucson examples
Tucson’s published permit-exemption guidance says grading outside a regulated zone may qualify for an exemption only when all listed conditions are satisfied, including limits on disturbed area, cut and fill depth, slope, material moved and drainage effects. Work in hillsides, floodplains, washes or other regulated areas can require review even when the project is relatively small.
How to Search Arizona Land Disturbance Permit Records Step by Step
Use the parcel address and assessor information to determine whether the site is inside an incorporated city or town or is regulated by the county. This prevents searching the wrong permit system.
Look for grading, drainage, clearing, site development, civil, development package, excavation, paving, stockpile or floodplain records. Use a permit number when available; otherwise try the address, parcel or project name supported by the portal.
If the work may meet the CGP criteria, search the ADEQ construction stormwater database by company, facility or county and compare the project details with the site you are researching.
For projects involving dust-generating operations, regulated floodplains, State Trust Land or other special conditions, search the responsible department rather than assuming everything appears in the general building permit portal.
Review the permit number, status, project description, approved plans, conditions, inspection history and related permits. An index result by itself may not show whether the project reached final approval.
If the record is old, incomplete, transferred to another system or unclear about final status, contact the responsible government department with the address and permit number.

What Plans and Information Should You Have Ready?
Document requirements depend on the jurisdiction and project, but grading and site-development applications commonly require enough information for reviewers to understand existing conditions, proposed earthwork, drainage and the limits of disturbance.
Sitework preparation checklist
- Property address and parcel number.
- Legal owner and applicant information.
- Project description and total disturbed area.
- Existing and proposed grades or elevations.
- Limits of grading or land disturbance.
- Cut, fill and stockpile locations and quantities when required.
- Drainage direction, retention or stormwater features.
- Driveways, access points and adjacent streets.
- Existing and proposed structures and utilities.
- Erosion, sediment and stabilization measures where applicable.
- Floodplain information when the property is within a regulated area.
- SWPPP materials when ADEQ construction stormwater coverage applies.
Pima County’s grading guidance, for example, identifies site-plan elements such as the graded-area boundary, structures, grade elevations, slopes, finished-floor elevation, scale, north arrow, property dimensions, paving and stabilization methods. Requirements can be different for a commercial project, subdivision, hillside site or floodplain property.
Dust, Floodplain, State Land and Excavation Checks
Maricopa County dust-control permits
Maricopa County Air Quality Department requires a Dust Control Permit for covered dust-generating operations disturbing 0.10 acre, or 4,356 square feet, or more. The threshold includes relevant project areas such as haul or access roads, staging and storage areas. This is much smaller than the one-acre threshold commonly associated with ADEQ construction stormwater coverage.
Public dust-control permit information and application functions are available through the county’s Dust and Miscellaneous Portal. Because dust permits are site-specific and the county updates fees and procedures, confirm the current requirements before work begins.
Floodplain disturbance
If grading or development affects a regulated floodplain, a separate floodplain review or permit may be required. Maricopa County’s Flood Control District, for example, lists floodplain use permit materials that can include an engineer’s report, site plan, site location, access information, grading plan and additional technical details depending on the project.
Check the applicable floodplain administrator before moving soil, placing fill, changing drainage or constructing within a mapped or locally regulated flood-hazard area.
Arizona State Trust Land
Projects on Arizona State Trust Land can require authorization from the Arizona State Land Department in addition to local and environmental approvals. ASLD application requirements vary by use, and some application categories specifically require information concerning anticipated ground-disturbing activity or planned improvements.
Confirm land ownership before assuming that a city or county grading permit is the only approval needed.
Call or contact Arizona 811 before excavation
Grading, trenching, digging, drilling and other excavation can affect underground utilities. Arizona’s damage-prevention system requires excavators to contact Arizona 811 before digging and to wait for the affected utility operators to respond under the applicable locate process. Follow the current timing and ticket instructions published by Arizona 811 for the specific job.
What Should You Check After Finding a Sitework Permit?
A permit record should be read in context. An application number, an approved plan and a final inspection are different milestones. When available, review the full record rather than relying on a single status label.
| Record detail | Why it matters | Next check |
|---|---|---|
| Permit or application number | Identifies the specific government record. | Use the exact number for future searches and agency questions. |
| Project scope | Shows what work the permit actually covers. | Compare it with the grading or disturbance visible or proposed on site. |
| Status | Indicates where the application or permit stands in the agency workflow. | Look for pending corrections, issuance, inspections and closeout information. |
| Approved plans | Define approved grading limits, drainage and site improvements. | Confirm you are reading the latest approved revision. |
| Related permits | Sitework can involve separate dust, floodplain, stormwater, building or right-of-way approvals. | Search each responsible agency if the local record references another approval. |
| Inspection / closeout | Issuance alone does not prove the work was completed or accepted. | Review final inspections, as-builts or termination requirements when applicable. |
For ADEQ CGP records, also verify whether the permit coverage is still active and whether the relevant project/operator information matches the site. ADEQ states that CGP coverage continues until an approved Notice of Termination or the general permit’s expiration, subject to the permit’s requirements.
What If You Cannot Find the Land Disturbance Record?
No address result
Confirm the jurisdiction and parcel number. Try the project, subdivision or permit number because civil permits may not be indexed exactly like building permits.
Only a building permit appears
Check for separate civil, grading, drainage, development package, floodplain, environmental or dust records. Related approvals may be stored in another module or department.
ADEQ search has no match
Confirm the project or company name, county and whether the project actually meets CGP coverage criteria. An absence from the CGP database is not proof that local grading approval was unnecessary.
Old records are missing online
Contact the jurisdiction’s records office. Tucson, for example, directs users to its records process when documents are not available through Property Research Online.
Permit is issued but work looks different
Compare the current site with the approved grading limits and plan revision. Ask the issuing agency whether a revision or additional authorization was required.
You are unsure which permit applies
Describe the total disturbed area, cut/fill, slopes, drainage changes, stockpiles, floodplain conditions and project location to the responsible planning or engineering department.
Arizona Land Disturbance Permit Search FAQs
Is there one statewide Arizona land disturbance permit?
No single local permit replaces every Arizona sitework approval. Grading and site-development permits are commonly handled by cities or counties, while ADEQ administers applicable construction stormwater coverage and other agencies may regulate dust, floodplains, rights-of-way or State Trust Land.
When does ADEQ construction stormwater coverage apply?
ADEQ’s Construction General Permit addresses covered construction activity disturbing one acre or more under the applicable discharge criteria. Smaller projects may also qualify when they are part of a larger common plan of development or sale that will ultimately disturb one acre or more.
Can I search Arizona construction stormwater permits online?
Yes. ADEQ provides a public Construction General Permit database with search fields including LTF ID, company name, facility name and county.
Does a one-acre rule mean smaller grading projects never need permits?
No. The one-acre figure is associated with ADEQ construction stormwater coverage, not every local grading rule. Cities and counties can require grading, drainage, dust, floodplain or other approvals at smaller disturbance levels.
Do I need a dust-control permit for grading in Maricopa County?
Maricopa County Air Quality Department states that a Dust Control Permit is required for covered dust-generating operations disturbing 0.10 acre, or 4,356 square feet, or more. Review the current county rules for your specific activity.
How can I find Tucson grading or development records?
Use the City of Tucson’s Property Research Online system for available parcel, permit and development activity records. The city states that approved and issued construction plans, permits and documents from recent years can be accessed through PRO, with a records process available when needed.
What if the property is in a floodplain?
Check the applicable floodplain administrator before disturbing the land. Grading, fill, structures and drainage changes in regulated flood-hazard areas can require a separate floodplain use permit or technical review.
Should I contact Arizona 811 even if I already have a permit?
Yes when the work involves excavation covered by Arizona’s underground-facility requirements. Permit approval does not replace the utility-location process. Follow Arizona 811’s current ticket instructions before digging.
Does an issued grading permit prove a project is complete?
No. Issuance authorizes work subject to the permit and approved plans. Check inspection results, required corrections, final approvals, as-built requirements and any related environmental closeout records.
Can a local grading permit replace an ADEQ CGP?
No. They address different regulatory programs. A project can require both local grading approval and ADEQ construction stormwater coverage, along with other site-specific permits.
What to Do Before Starting Arizona Sitework
First verify the parcel’s jurisdiction. Next identify the full disturbance footprint and the kind of work involved: clearing, grading, excavation, stockpiling, paving, drainage alteration or development in a sensitive area. Search the local development portal and then check ADEQ and any other agency that regulates the specific project conditions.
Do not begin work based only on a generic threshold or an old permit record. Requirements can change, and the correct approval depends on the location, acreage, drainage, slope, floodplain, air-quality district, land ownership and project design.
