Do you need a building permit in Perry, Missouri?

Perry requires a city building-permit application before construction, but the city code exempts construction, replacement, alterations or repairs that do not change the existing structure footprint or the property elevation or grade.4 Ask the city to confirm how that exemption applies to your proposed work before starting.4 Perry building-permit applications include a sketch or drawing, a description of the work and a construction-cost estimate; issuance depends on compliance with city zoning and subdivision ordinances and payment of the fee.1 The city building permit remains valid for 1 year after issuance.1

Who handles building permits and zoning in Perry?

Take Perry building-permit questions to the city: the city receives the application and issues the building permit after zoning and subdivision compliance is established.1 Perry City Hall is at 127 E Main Street; ask there for the application and the zoning enforcement officer.7 The building-permit fee is $50 per structure, with an additional $75 penalty for starting construction without the required building permit.4 City building approval does not replace private-sewage review: Perry requires city inspection of private sewage installations, while the Ralls County Health Department handles onsite wastewater construction authorization.35

What does Perry zoning mean for RVs, tiny homes and mobile homes?

Perry evaluates proposed construction against its own zoning and subdivision ordinances, so ask the city to identify the parcel’s zoning district and applicable lot and yard requirements before settling on a house design.1 We could not confirm Perry-specific permission for living in an RV, temporary camping, tiny-home occupancy, accessory dwelling occupancy or a minimum dwelling floor area; ask the city zoning enforcement officer about the intended use.1 Perry mobile-home placement is subject to Building Inspector inspection during construction, erection and placement, but that inspection provision alone does not authorize residential occupancy on a particular lot.6

How do sewer connections and septic permits work inside Perry?

For human-occupancy properties meeting Perry’s street, alley or right-of-way conditions, connection to the city sewer is required at the owner’s expense within 90 days after official notice when the sewer is within 100 feet of the property line.2 If public sewer is unavailable, Perry allows a compliant private sewage disposal system; a later public-sewer connection requires abandonment or filling of the private system as specified by the city.2 The Ralls County Health Department’s procedure requires a septic construction permit for new systems regardless of lot size, and for repairs, replacements or upgrades.5 Perry also requires final city inspection before underground portions are covered, so arrange both authorities’ requirements before backfilling.3

What are the steps to building a home in Perry?

  1. Start with the city: confirm the proposed construction meets Perry zoning and subdivision ordinances, then prepare the city building-permit application with a drawing and cost estimate.1
  2. Check public-sewer availability before designing a private sewage system, because Perry requires connection where the city sewer meets the distance and notice conditions.2
  3. If septic is needed, contact the Ralls County Health Department for its soil-evaluation and registered-installer process, and submit the signed application for approval before septic construction begins.5
  4. Obtain the city building permit before construction and coordinate the city’s private-sewage final inspection before covering underground components.43

What should you check before buying land in Perry?

Confirm whether the parcel is inside Perry before choosing an approval office: Ralls County’s zoning order applies to unincorporated land, so use the Ralls County guide for property outside city limits.8 For land inside Perry, ask the city about zoning compliance and sewer availability before committing to a building layout.12 Missouri requires some form of floodplain development permit for all development in a floodplain; ask Perry City Hall to identify the applicable community floodplain administrator.9 We could not confirm Perry-specific well approval, comprehensive building-code adoption, owner-builder exemptions or certificate-of-occupancy requirements; bring those questions to the city before purchasing.1

Watch-outs

  • Do not assume a large lot avoids septic permitting: the Ralls County Health Department’s procedure requires a construction permit regardless of lot size for new systems.5
  • Perry’s mobile-home inspection provision does not settle RV or tiny-home occupancy; ask the city zoning enforcement officer to confirm the proposed residential use.61
  • Private sewage approval in Perry includes a city final inspection before underground portions are covered.3
