Do you need a building permit in Cibolo, Texas?

Cibolo requires building permits for new construction, additions, structural changes, electrical work, plumbing and mechanical systems.¹ Cibolo typically does not require a building permit for minor cosmetic repairs such as painting, flooring replacement or cabinet replacement; ask Building Permits & Inspections about the exact scope before starting.¹ Cibolo has adopted the 2021 International Residential Code with local amendments for single-family and two-family dwellings.⁵ A small project and a new house therefore need different permit checks: describe the work to the city building office rather than assuming all home improvements are exempt.¹

Who issues building permits in Cibolo, and how do you apply?

Cibolo Building Permits & Inspections provides building permit applications, permit tracking and inspection scheduling through MGO Connect.⁷ Call (210) 658-4175 or email [email protected]; the office is at 201 West Loop 539, Cibolo, TX 78108.⁷ Applicants must create an account before submitting, and contractors must complete city contractor registration.⁷ For residential work, generally prepare a site plan showing property lines and the structure location, a project description or construction plans, contractor information when hiring a contractor, and proof of ownership if required.¹ Cibolo bases building permit fees on project type and construction valuation; request the applicable amount for your scope.¹

Does Cibolo have zoning, and what about RVs and tiny homes?

Cibolo has city zoning, and a parcel’s zoning status depends on the official Cibolo Zoning Map and the applicable Unified Development Code district regulations.²⁴ Cibolo Planning Division maintains the land-development regulations and accepts development-review applications through MGO Connect.⁸ Ask Planning to identify the parcel’s district and confirm permitted residential uses, minimum lot and dwelling sizes, setbacks, height and coverage before committing to a design.⁴ We could not confirm a complete answer for RV residence, tiny-home occupancy or accessory dwellings in Cibolo; ask the Planning Division to address your proposed use in writing before buying land for that purpose.⁸

How do septic permits work inside Cibolo?

A proposed septic system inside Cibolo requires approval from both Guadalupe County and the city.³ A septic permit is required regardless of lot size or acreage, and Guadalupe County Environmental Health or TCEQ must issue the License to Operate.⁶ Do not assume the Texas acreage exemption removes the local requirement: Guadalupe County expressly requires septic permits for all on-site sewage facilities regardless of acreage.⁹ Start with Guadalupe County Environmental Health and coordinate the city approval before installing or altering a system.³ Guadalupe County has only 4.3% of soils rated not limited for conventional septic drain fields; that countywide rating calls for a site evaluation and potentially an engineered system, rather than proving septic impossible on a Cibolo lot.¹⁰

Building a home in Cibolo: what are the steps, in order?

First, ask Cibolo Planning to confirm the parcel’s zoning district and the applicable UDC requirements for the proposed home.⁴ Next, resolve any septic proposal with Guadalupe County Environmental Health and Cibolo, because both approvals are required.³ Prepare the city’s residential application documents, create an MGO Connect account, and submit the building permit application with the applicable fees.¹⁷ During construction, request required inspections through the portal and have the builder submit the required foundation elevation measurements for a new home.¹ For applicable projects, Cibolo issues a Certificate of Occupancy after required inspections pass and fees are paid; required screening and landscaping must also be in place before issuance.¹¹¹

What should you check before buying land in Cibolo?

Confirm whether the parcel is inside Cibolo city limits and ask Planning which city zoning district applies; Cibolo’s district regulations determine the parcel’s zoning status.⁴ For land outside the city, use the Guadalupe County guide for the unincorporated-area zoning answer rather than carrying Cibolo’s zoning rules across the boundary.¹² We could not confirm a Cibolo-specific private-well rule; ask Guadalupe County Environmental Health to help identify the water-well authority for the parcel.¹³ Wells within Guadalupe County Groundwater Conservation District boundaries require registration and a Notice of Intent before new drilling, with permits for non-exempt wells; first confirm whether the parcel is in that district.¹⁴ Ask Cibolo Planning to identify the floodplain review needed for your proposed development.⁸

Watch-outs

• Cibolo septic approval is additional to county approval; a city building permit does not replace the septic License to Operate.³⁶
• We could not confirm a general Cibolo owner-builder exemption; ask Building Permits & Inspections before treating homeowner work as exempt.¹
• New Cibolo homes require foundation elevation measurements submitted by the builder.¹
