Do you need a building permit in Marshall, TX?

Marshall’s Permits and Inspections Division issues building permits and performs inspections for residential and commercial construction projects.¹ The city’s published building guide says construction may begin after the building permit has been issued, and the building permit process requires site-plan approval.² Start with the residential application and ask the city which additional applications your project needs: Marshall publishes accessory-structure, irrigation, swimming-pool and certificate-of-occupancy applications as well.¹⁰ Marshall accepts online applications or the appropriate completed application, and each application must be fully completed before submission to the City of Marshall Permits and Inspection Department.¹⁰

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

Marshall Permits & Inspections is the city office for residential and commercial building permits, plan review and final inspections.¹ Call 903-934-7994 or visit 401 S Alamo Blvd., Marshall, TX 75670.¹ The city’s online permit portal accepts applications and lets readers search existing permits and licenses.¹ For a parcel’s zoning and land-use questions, contact Marshall Planning and Development at (903) 934-7994; zoning administration is part of that department’s work.⁸ Septic questions also need attention from the city plumbing inspector and Harrison County Environmental Health, rather than treating a building permit as septic approval.¹¹⁵

Does Marshall have zoning, and can you live in an RV or tiny home?

Marshall has city zoning, a zoning ordinance and an official zoning map; the Planning and Zoning Commission considers zoning changes and special-use permits.³⁶ Before buying, ask Planning and Development to identify the parcel’s district and the rules for your proposed dwelling, setbacks and lot dimensions.⁸ We could not confirm Marshall’s private-lot RV occupancy, tiny-home occupancy, accessory-dwelling or minimum-dwelling-size rules; ask Planning and Development about the exact use you intend.⁸ Marshall’s stated 35-foot height limit concerns structures intended for occupancy in mobile-home parks, so that limit does not establish permission to live in an RV on a separate private lot.¹²

How do septic permits work inside Marshall?

Installing a septic tank inside Marshall city limits requires the owner or contractor to obtain a permit from the city plumbing inspector before installation.⁴ Marshall’s sanitation rules also require connection where a public sewer is within 100 feet, subject to ordinance exceptions; drainage-field work needs an approved percolation test and plumbing-inspector approval before covering.⁷ Harrison County Environmental Health administers the local OSSF program, so ask the county office and city plumbing inspector which approvals apply to your address.⁵¹¹ Texas’s 10-acre OSSF exemption requires a licensed site evaluation, only a single-family dwelling on the tract, on-property disposal, no nuisance or groundwater pollution, all system parts at least 100 feet from property lines and compliance with construction standards; local requirements may be stricter.¹³ Do not assume that exemption removes Marshall’s separate city septic-tank permit requirement.¹³⁴

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

1. Ask Marshall Planning and Development to confirm zoning for the parcel and proposed residential use.⁸
2. Resolve sewer availability with the city plumbing inspector; a public sewer within 100 feet can require connection, and septic work needs city approval.⁷
3. Complete the appropriate city building permit application and obtain site-plan approval through the building permit process.¹⁰²
4. Wait for the building permit before starting construction, then arrange the city’s required inspections.²¹
5. Obtain final inspection approval and the certificate of occupancy; Marshall’s guide says the certificate is issued after all final inspections have been approved.²

What should you check before buying land in Marshall?

For a parcel being split, Marshall’s Planning and Zoning Commission reviews subdivision plats inside city limits and within 1 mile of city limits; ask the city about the proposed division before relying on a seller’s sketch.⁹ Marshall’s building guide requires a driveway permit to retain or modify an existing driveway when vacant property is developed, new structures are constructed or land use changes.² We could not confirm the current city requirements for private wells or an agricultural construction exemption; take those questions to Planning and Development and Permits & Inspections.⁸¹ For land outside Marshall, consult the Harrison County guide: Marshall’s zoning answer applies inside city limits, while the county’s separate rules address unincorporated land.³¹⁴

Watch-outs

• A large tract does not automatically avoid Marshall’s city septic-tank permit or sewer-connection requirements; ask the city plumbing inspector before choosing off-grid sanitation.⁴⁷
• We could not confirm a Marshall owner-builder exemption; ask Permits & Inspections which homeowner work and contractor requirements apply to your project.¹
• Marshall’s subdivision review extends within 1 mile of city limits, according to the Planning and Zoning Commission page; ask the city about a boundary-area parcel.⁹
