Does Collinsville have zoning, and what does it mean for a building site?

Collinsville has municipal zoning inside city limits.2 Collinsville Development Services includes City Planning and Building Inspections and Permitting, and assists with rezoning, platting, lot splits, special exceptions and variances.9 Ask Development Services to identify the parcel’s zoning district and provide the applicable lot-size, setback, height and lot-coverage schedule before choosing a house footprint. We could not confirm Collinsville’s residential dimensional figures or a city agricultural exemption; ask Development Services for the standards that apply to the proposed use. Do not substitute an unincorporated Tulsa County district schedule for the city’s zoning review.10

Do you need a building permit in Collinsville, Oklahoma?

Collinsville publishes building permit fees based on the International Code Council Building Valuation Data formula, rather than a single flat price for every building.5 The city fee schedule separately lists residential roofing permits at $25 and electrical permits at $25 each.5 Oklahoma’s minimum building codes apply inside Collinsville, and municipalities may enforce higher standards.11 We could not confirm the complete Collinsville building permit trigger or exemption list. Before starting a home, addition, barn or shed, ask the city Permitting Specialist which building and trade applications the specific project needs.1

Who handles Collinsville building permit applications and zoning questions?

The Collinsville Permitting Specialist handles building permit inquiries, and the city directs building permit applications to its GovWell portal.1 Contact Development Services at 918-371-1012 to discuss the proposed construction or arrange an in-person development appointment.9 Include a site plan with a permitting inquiry when applicable, as the city requests.1 Bring questions about zoning, lot splits or a variance to Development Services as well.9 Septic authorizations for Collinsville property remain with Oklahoma DEQ; submitting a city building application does not replace the DEQ Authorization to Construct required for a new or modified septic system.36

How do septic permits work inside Collinsville?

Before installing a new septic system or modifying an existing system in Collinsville, obtain an Oklahoma DEQ Authorization to Construct.6 DEQ must review the Report for On-Site Sewage before issuing that authorization, and assigns the review to a local Environmental Specialist based on the property location.63 New and modified systems must be inspected and approved before operation, either by DEQ or through the certified-installer process.12 Alternative sewage systems also require DEQ approval before installation.13 Ask DEQ about soil testing and system design before committing to a septic-dependent site; the ECLS program covers both.14

Can you live in an RV or tiny home in Collinsville?

Collinsville’s RV rule for mapped flood zones offers alternatives: remain on site fewer than 180 consecutive days, remain fully licensed and ready for highway use, or meet the permit, elevation and anchoring requirements for manufactured homes.7 A highway-ready RV must use wheels or its jacking system, have only quick-disconnect utilities and security devices, and have no permanently attached additions.7 That provision addresses floodplain compliance, rather than general permission to occupy an RV on a residential lot.7 We could not confirm Collinsville’s general private-lot RV occupancy, temporary camping or tiny-home occupancy rules; ask Development Services about the proposed dwelling and parcel before moving in.

Building a home in Collinsville: what should you do first?

  1. Discuss the parcel, zoning district and proposed use with Collinsville Development Services; request an appointment for a development discussion.9
  2. Send the Permitting Specialist a site plan when applicable and ask for the required building applications, inspections and occupancy approvals; use the city’s GovWell portal for building permit applications.1
  3. If the project uses septic, arrange DEQ review and obtain the Authorization to Construct before installing or modifying the system.6
  4. Ask the city about mapped flood hazards: new residential construction and substantial improvements in applicable special flood hazard areas require the lowest floor, including basement, at least 2 feet above base flood elevation.15
  5. Complete the required septic inspection and approval before putting a new or modified system into operation.12

What should you check before buying land in Collinsville?

Ask Collinsville Development Services to resolve zoning and development questions for the actual parcel before treating the site as buildable.9 We could not confirm the city’s general public-water or sewer connection rule, driveway access requirements, or owner-builder building permit exemption; request those answers from the city for the intended project. Domestic groundwater use does not require an OWRB water-use permit, while non-domestic uses remain subject to OWRB regulation.8 That groundwater exemption does not establish a city utility-connection exemption.8 For a septic-dependent purchase, take the lot layout and proposed residence to DEQ: system design depends on lot size and shape, residence size and soil-test results.13

Watch-outs

  • Collinsville’s floodplain RV alternatives do not establish general permission to live in an RV on a private residential lot.7
  • City building permit applications and DEQ septic authorizations are separate approvals; obtain the septic Authorization to Construct before new installation or modification.16
  • We could not confirm city lot-size, setback, tiny-home or owner-builder building permit rules; ask Collinsville Development Services before buying or starting work.9
