Building permits, zoning and land rules in Arkadelphia, Arkansas

Arkadelphia, Arkansas requires a building permit from the city, and city zoning districts such as R-1 control what can be built on a lot.12 Septic systems are permitted by the Arkansas Department of Health, not the city, and city code limits private systems where a public sewer is nearby.34 Clark County, which surrounds the city, has no building department of its own that we could confirm.

Do you need a building permit in Arkadelphia, Arkansas?

Yes. Arkadelphia's land-use ordinance requires every building permit application to include a plan, in duplicate and drawn to scale, showing the lot's actual dimensions, the size of the building and its location on the lot.1 The city's Building Department issues permits for all types of work involved in constructing or repairing a structure.10 Arkadelphia has adopted standard building codes by reference.11 Arkansas building codes are also mandatory statewide minimums, even in areas where no permit or inspection is required.12

We could not confirm the city's permit fees, inspection steps or certificate-of-occupancy rules; ask the Building Department.

Who issues building permits in Arkadelphia, and how do you reach them?

The Arkadelphia Building Department handles building, plumbing, electrical and heating-and-cooling permits and enforces the city's building, fire, gas and housing codes.10 Call 870-246-9864 or visit 700 Clay Street.10 Septic permits are not part of that office; they come from the Arkansas Department of Health.13

Does Arkadelphia have zoning, and what does it mean for homes?

Yes. Arkadelphia zones land inside city limits by district, and uses remain subject to the district's requirements.2 In the R-1 residential district, a one-family dwelling needs a lot of at least 6000 square feet.5 Structures, including accessory buildings, may cover no more than 35 percent of the lot.14 Each R-1 dwelling must have 20 feet of heated living space on each side, on a permanent foundation.9

The city's Unified Development Code and zoning requirements are posted on the Building Department page.10 We could not confirm city rules for tiny homes, accessory dwellings or living in an RV on a lot; ask the Building Department before you buy.

How do septic permits work in Arkadelphia?

The Arkansas Department of Health issues septic permits, not the city. State rules make it unlawful to begin operating an onsite wastewater system without a permit.6 Arkadelphia code bars privies, cesspools and similar facilities except as the chapter provides.4 When a public sanitary sewer is within 300 feet, the owner must connect within 60 days of official notice.7

Soils in Clark County are tough on conventional systems: only 2.9% of soils rate without severe limits for a drain field, so expect a site evaluation and possibly an engineered system.15 State rules do not approve holding tanks for residences.16 Contact the Department of Health's Onsite Wastewater Program at 501-661-2171.13

What stays with Clark County and the state when you build in Arkadelphia?

Septic permits stay with the Arkansas Department of Health for every address in Clark County, city or not.3 A driveway onto a state highway needs a permit from the Arkansas Department of Transportation.17 Anyone building their own home is exempt from residential contractor licensing only for one residence per calendar year.8 That exemption concerns contractor licensing; it does not say the city waives a building permit. We could not confirm whether the city has a separate owner-builder rule.

Building a home in Arkadelphia: the steps, in order

  1. Ask the Building Department (870-246-9864) which zoning district your lot is in and what it requires.10
  2. Find out whether a public sewer lies within 300 feet of the building, since that triggers a connection requirement.7
  3. If no sewer applies, apply to the Department of Health (501-661-2171) for an onsite wastewater permit.13
  4. Submit the building permit application with a scaled plan to the Building Department.110
  5. Check floodplain status before you design; the city lists a floodplain development permit application with its permit forms.10

Watch-outs

  • Only 2.9% of Clark County soils rate without severe limits for a conventional septic field, so budget for a site evaluation.15
  • City code may require sewer connection within 60 days of notice when a public sewer is within 300 feet.7
  • Residential holding tanks are not approved as a septic system under state rules.16
