Building permits, zoning and septic rules in Camden County, Missouri

Camden County requires construction permits for covered work in its applicable unincorporated Lake Area jurisdiction, not automatically countywide¹. Covered work includes homes, commercial structures, temporary construction structures and nonagricultural accessory structures of 120 square feet or larger; agricultural structures are exempt from the construction-permit requirement². The construction schedule lists $100 for a single-family home and $50 for a single-family accessory structure; confirm the applicable charge with Planning & Zoning because the County Commission sets fees by resolution^6,7. Starting construction before an approved permit is issued doubles the applicable fee⁷. Inside Village of Four Seasons, the Village handles building permits; county septic-permit criteria still apply^8,9. We could not confirm a general technical building code, certificate-of-occupancy rule or owner-builder exemption; ask Lake Area Planning & Zoning.

Camden County's Lake Area Planning & Zoning Department is at 1 Court Circle, Suite 15, Camdenton, MO 65020, and its phone number is 573-346-4440¹. Start there for construction and zoning permits, the parcel's district and confirmation that the land is within the county-administered Lake District area^1,2. Camden County requires floodplain approval of structure location and elevation for covered waterway and lakefront sites; other site plans showing possible floodplain noncompliance may also require a Floodplain Development Permit Application^1,2. The county construction-permit signoff sheet also requires approval for an impact fee or access permit from the county highway department or the applicable local road district¹. Camden County Road & Bridge can be reached at 573-346-4471¹⁰. A driveway constructed or modified within Missouri Department of Transportation right-of-way needs a separate state permit¹¹.

Camden County zoning covers Commission-designated lands in applicable unincorporated Lake District areas, with district maps available through county GIS^2,12. Inside Village of Four Seasons, the Village sets zoning; county septic-permit criteria still apply^9,13. New R-1 and R-2 lots under 0.92 acre need permitted centralized or remote onsite wastewater service and department signoff⁴. Camden County’s revised R-1/R-2 minimum setbacks are 15 feet from the road right-of-way in front, 10 feet on the side and 15 feet in the rear, subject to separate lakefront provisions⁴. The older R-2 code specifies a 560-square-foot minimum dwelling and a 50-foot maximum structure height above finished grade; ask Planning & Zoning whether later revisions change those limits for your parcel².

The Camden County Wastewater Department handles county onsite-wastewater permitting³. Septic permits cover new construction, replacement and repair on residential lots under 3 acres, Lake of the Ozarks lots regardless of size, lots with multiple single-family residences, multifamily development and commercial development below 3,000 gallons per day³. A qualifying single-family lot of at least 3 acres may be excluded only if every system point is more than 10 feet from adjoining property lines, effluent does not leave the property or contaminate water, and no nuisance results; qualifying lake-adjacent lots cannot use the exclusion³. County site evaluation precedes septic-permit issuance³. Remodeling, rebuilding and additions requiring Planning & Zoning building permits also require an existing onsite-system inspection by a state-registered inspector, unless the system has a valid operating permit¹⁴. Only 22.1% of county soils are rated without severe limitations for conventional drain fields, so check feasibility early⁵. The county lists a $150 septic fee; ask Wastewater whether the statewide temporary application-fee suspension affects your application^3,9.

In Camden County’s R-1 district, using an RV as a residence requires conditional-use approval and compliance with wastewater-treatment, potable-water and setback rules; that conditional use is unavailable in R-2 and R-3⁴. The published conditional-use permit fee is $600, with possible additional hearing-mailing charges¹. In R-3, portable tiny homes measuring 400 to 600 square feet are addressed within RV condominium plats, rather than as blanket approval on private parcels⁴. Tiny-home developments in Camden County’s zoning district must provide appropriate electric, water and wastewater service, including central or public systems; R-5 developments also need community shower/restroom facilities if units lack a shower and toilet². Camden County requires sanitary domestic-sewage disposal through a regulated sewer or compliant onsite system for buildings where people live, work or assemble, including off-grid homes³. The A-R district permits Class A and Class B manufactured homes, while Class C homes are barred within the regulated area^2,4. Ask Lake Area Planning & Zoning to classify the proposed unit and occupancy before buying or placing it.

1. Ask Lake Area Planning & Zoning whether the parcel is in the county-administered Lake District area and identify its district².

1. Confirm the Construction Permit requirement; prepare parcel identification, directions, ownership proof or owner authorization, a scaled site plan, wastewater or sewer information and required signoffs¹.

1. Ask the Wastewater Department whether the project needs a septic permit or meets the narrow acreage-based exclusion, and have the site evaluated before permit issuance³.

1. Include floodplain details and elevations in the site plan, obtain required waterway or lakefront approval, and secure the applicable road-access signoff^1,2.

1. Submit the complete application and fee to Planning & Zoning, wait for issuance and post the permit; the published process gives the permit one-year validity with a possible administrative extension².

1. Schedule the required Lake Area location, foundation and substantially complete structure inspections¹.

Confirm the parcel's planning jurisdiction and zoning district before buying². A subdivision on covered unincorporated land needs a plat or administrative survey prepared under county and Missouri rules, recorded and reviewed by the Planning Administrator⁴. For a major subdivision or multiple-use preliminary plat, allow at least 30 days before the Planning Commission hearing and arrange the required pre-application conference unless waived⁴. Check lake adjacency and flood exposure separately: Lake of the Ozarks lots require septic permits regardless of acreage, while covered waterway and lakefront sites need floodplain location and elevation approval^1,3. Missouri permits landowners to install their own well or pump without a permit under applicable law and rules; hired well and pump installers need the appropriate state installation permits¹⁵.
