Do you need a building permit in Charleston, AR?

Charleston publishes a building and construction permit process requiring an application, plans submitted to city offices, fees and inspections.¹ Charleston has adopted the 2021 Arkansas Fire Prevention Code, including its fire, building and residential volumes.⁵ All phases of commercial and noncommercial building construction in Charleston are subject to inspection by the City Building Inspector.²

Start with Charleston Building Inspections & Permits at (479) 965-6265 and ask which application documents and inspection stages apply to your proposed home or alteration.⁸ The city says the application process and required documents may vary with the permit and construction type.¹

Does Charleston have zoning, lot-size limits or building setbacks?

We could not confirm Charleston’s zoning districts, minimum lot size, minimum dwelling size, lot coverage or building-height limits; ask Charleston City Hall for the requirements at the exact parcel before buying.⁴ Request a written answer about building setbacks, accessory dwellings and subdivision approval before designing a small home or splitting land.⁴

A septic setback is a separate requirement: Arkansas onsite wastewater facilities must generally be at least 10 feet from property lines and buildings, with greater distances where local conditions demand.⁹ Do not use that septic separation as the city’s building setback; ask the city to identify the applicable building location requirements.⁹⁴

How do septic permits work inside Charleston?

For a Charleston home using onsite wastewater, submit the application and detailed plans to the Arkansas Department of Health or its Authorized Agent for approval before construction of the residence.³ The Franklin County Health Unit in Ozark is a local contact at 479-667-2555.¹⁰ Charleston’s building permit process and state septic approval are separate steps.¹³

Arkansas requires sanitary sewer connection when sewer is within 300 feet of the building’s sewer-exit point, available, and connectable without crossing another person’s property.¹¹ Where septic is appropriate, the review fee is $30 for a structure of 1,500 square feet or less.³ A Charleston onsite wastewater system must be inspected and approved, and cannot be used until the Permit for Operation is issued.¹²

Can you live in an RV, tiny home or mobile home in Charleston?

We could not confirm permission for private-lot RV occupancy or tiny-home occupancy in Charleston; ask Charleston Building Inspections & Permits about the proposed structure, location and duration before relying on either as housing while building.⁸ Ask separately about a tiny home on a foundation, a home on wheels and temporary RV use.⁸

Charleston prohibits parking, installing or maintaining mobile homes on private property outside a licensed mobile-home park, subject to the chapter’s exceptions; existing units are unaffected while remaining in their present location.⁶ A licensed mobile-home park requires City Council site-plan approval and compliance with city requirements.⁶

What are the steps for building a home in Charleston?

1. Ask Charleston City Hall to confirm the parcel’s city status and applicable land-use requirements, including the unconfirmed zoning and dimensional rules.⁴
2. Establish whether sewer connection is required; when sewer is within 300 feet of the building’s sewer-exit point, available and connectable without crossing another person’s property, Arkansas requires connection.¹¹
3. If using septic, obtain ADH or Authorized Agent approval of the application and detailed plans before residence construction.³
4. Complete the city building application, submit required plans for review and pay the applicable fees.¹
5. Arrange required construction inspections and obtain the city Certificate of Occupancy after final inspections; obtain the separate septic Permit for Operation before using an onsite wastewater system.¹¹²

What should you check before buying land in Charleston?

Ask Charleston’s building inspector for the project’s fee calculation, required plans and inspection schedule before setting a construction budget.⁸ Arkansas’s owner-builder exemption concerns contractor licensing and does not eliminate applicable building-code, building-permit, inspection or zoning requirements; the own-residence exemption ends if the person builds more than 1 residence in a calendar year.⁷

For a private residential well, we could not confirm Charleston’s permit requirement; ask City Hall to identify the responsible water authority before commissioning drilling.⁴ Work on access driveways within Arkansas State Highway right-of-way requires a permit from the highway department before work begins.¹³ For land outside city limits, use the Franklin County guide for the unincorporated-area building-permit answer rather than applying Charleston’s city process.¹⁴¹

Watch-outs

• Charleston’s zoning, private-lot RV occupancy and tiny-home occupancy remain unconfirmed; get a parcel-specific answer from City Hall and the city building inspector before buying.⁴⁸
• A nearby available sewer can rule out onsite wastewater and privies when the state connection conditions are met.¹⁵
• The owner-builder contractor-license exemption does not waive Charleston’s building-permit or inspection requirements.⁷¹
