Do you need a building permit in the Town of Parker, AZ?

Parker requires building permits for development and construction addressed by its adopted building codes and other town policies, codes or ordinances; the building permit must be obtained before work begins.1 Parker also requires zoning clearance for development and construction covered by the zoning title, and for a change in use.1

Parker has adopted the 2018 International Building Code and International Residential Code, with IRC Appendix Q for tiny houses.4 Treat the building permit and zoning clearance as separate questions when discussing your project with town Community Development.1

Who handles building permits and zoning in the Town of Parker?

For construction inside Parker, start with the town Community Development page, which provides Building Department and Planning & Zoning contacts.85 To schedule a Parker building inspection, call 928-669-9265 *1019 or email [email protected].8 Direct zoning questions to [email protected].5

Ask the Building Department for the application requirements, current building-permit fees, inspection sequence and occupancy approval needed for your particular project.8 For land outside town limits, see the La Paz County guide: the county Building and Safety Department regulates development in unincorporated La Paz County.9

Does the Town of Parker have zoning, lot-size rules and setbacks?

Parker has its own zoning ordinance for land, buildings and structures within town limits.2 Parker uses residential, commercial, industrial, open-space/public-use and overlay districts, and the zoning map is maintained in the zoning administrator’s office with a copy filed with the town clerk.10

In Parker’s RR-20 rural residential district, the minimum lot area is 20 acres and minimum lot width is 660 feet.6 RR-20 requires front, street-side and rear setbacks of 60 feet and a side setback of 30 feet.11 RR-20 also limits building height to 40 feet and lot coverage to 5 percent.1213 Ask town Planning & Zoning to identify the parcel’s district before applying these RR-20 standards to a proposed home.5

How do septic permits work inside the Town of Parker?

La Paz County Community Development processes applications and permits for conventional onsite septic wastewater systems in La Paz County under ADEQ delegation.3 Arizona’s onsite-wastewater permit applications go to the county where the property is located.14 The county’s services include site-investigation monitoring, installation-plan review, construction authorizations, new-system inspections, discharge authorizations and ownership transfers.3

Before designing a septic system in Parker, ask town Community Development whether the parcel must connect to public sewer, and ask La Paz County Community Development about the proposed onsite system.515 We could not confirm Parker’s sewer-connection availability or distance threshold; resolve that question with town Community Development before budgeting for septic.5

Can you live in an RV or tiny home in the Town of Parker?

Parker adopted IRC Appendix Q Tiny Houses as part of its residential building code.4 That code adoption alone does not establish which Parker zoning districts allow your proposed tiny house as a residence; ask town Planning & Zoning about the parcel, dwelling type and intended occupancy.4105

We could not confirm permission for living in an RV on private land in Parker, including during home construction; ask town Planning & Zoning before relying on an RV as temporary housing.5 Bring the same office your questions about manufactured homes, accessory dwellings and minimum home size, because those Parker-specific occupancy standards remain unconfirmed.5

Building a home in the Town of Parker: what steps come first?

  1. Ask Parker Planning & Zoning to confirm the parcel’s district, overlays and proposed residential use against the town zoning map.105
  2. Discuss the required zoning clearance and building permit with Parker Community Development before starting covered development or construction.1
  3. Resolve sewer availability with the town; if proposing conventional septic, contact La Paz County Community Development about site investigation, installation plans and construction authorization.53
  4. Ask the Parker Building Department for the project’s inspection sequence and how to schedule inspections.8

Arizona offers a conditional owner-builder exemption from contractor licensing for work intended solely for the owner’s occupancy, rather than public occupancy, sale or rent; that exemption does not remove Parker’s building-permit requirement.71

Watch-outs

  • Parker’s RR-20 acreage and setbacks are district-specific; ask town Planning & Zoning which district and overlays cover your parcel.6115
  • We could not confirm Parker-specific private-well, floodplain-development or driveway-approval requirements; ask town Community Development to identify the reviewing offices before buying.5
  • Parker’s tiny-house code adoption does not settle residential zoning permission for a specific parcel; confirm the proposed use with town Planning & Zoning.45
