Building permits, zoning and land rules in Richmond, Texas

Richmond, Texas requires building permits for covered construction and repairs inside city limits, with specific exemptions for minor work.1 Richmond sets its own zoning; Fort Bend County’s lack of county zoning does not remove city restrictions.23 Septic permitting is separate from city building approval: ask Fort Bend County Environmental Health to confirm who serves a Richmond address before planning an on-site system.4

Do you need a building permit in Richmond, Texas?

Richmond requires a building permit before covered improvement, construction, reconstruction or repair of a new or existing building or structure.1 Richmond’s rule includes specific exemptions for listed minor work, repairs and certain structures or equipment; ask the Permit Office to identify the exemption that fits your project before starting.19 Starting covered work before the city issues a building permit subjects the work to double the required permit fee.1

Richmond has adopted the 2024 International Residential Code with city amendments.10 A Richmond certificate of occupancy is required before using land, a building or a structure for which a building permit is or was required; partial certificates are unavailable for single-family dwellings and duplexes.8

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

Contact the Richmond Permit Office for city building permit questions and Richmond Planning for zoning and land-use questions.911 Richmond’s building page directs new building permit applications to MyGovernmentOnline and provides an account link; select Richmond as the jurisdiction.9 The city’s customer portal supports online inspection requests as well as building permit applications.9

Richmond Planning administers the Unified Development Code and regulates land use within the city’s corporate limits.11 City building approval does not settle septic approval: the county OSSF order includes incorporated cities only where intergovernmental contracts apply, so confirm Richmond address coverage with Environmental Health.4 We could not confirm current Richmond building permit fee amounts or a general owner-builder exemption; ask the Permit Office for the applicable fee schedule and project requirements.9

Does Richmond have zoning, and what does it mean for a home?

Richmond has zoning, with uses classified as permitted, limited, conditional or prohibited according to the property’s district.2 Before choosing a house design, ask Richmond Planning to identify the parcel’s district and applicable residential standards.11 Richmond’s utility requirements also vary by district and neighborhood type: the SR standard residential neighborhood allows on-site utilities, while the SR planned residential neighborhood allows on-site/public utilities.6

Richmond allows accessory dwelling units only in eligible districts and only as accessories to detached single-family principal buildings, with no more than 1 ADU per lot.7 Richmond lists manufactured homes as a limited use in SR and GR and prohibits them in the other districts shown in its use table.12 We could not confirm a minimum dwelling floor area or complete lot-coverage limits for Richmond; ask Planning for the district’s lot-size, setback and coverage table before committing to a layout.11

How do septic permits work inside Richmond?

Richmond’s zoning determines whether a residential project may use on-site utilities rather than public utilities; permission to use septic is therefore a city land-use question before it becomes a wastewater design question.6 Texas generally requires a permit and approved plan to construct, alter, repair, extend and operate an on-site sewage facility.13

Fort Bend County Environmental Health operates the county OSSF program, but the county order limits municipal coverage to incorporated cities with intergovernmental contracts; we could not confirm that coverage for Richmond.144 Ask Environmental Health to identify the permitting authority for your Richmond parcel before submitting a design.15 Where Fort Bend County’s OSSF rules apply, construction, alteration, extension and repair must be permitted regardless of tract size, and homeowner installation is unavailable unless the owner is a Registered Installer.4 Do not assume Texas’s 10-acre exemption overrides those local requirements.134

Can you live in an RV or tiny home on land in Richmond?

Richmond’s temporary recreational camping defense is narrow: rear-yard camping on private property containing an occupied main building may last no more than 48 hours.5 That provision does not establish permission to live indefinitely in an RV on a vacant Richmond lot while building a home.5 Richmond also recognizes camping in a city-approved RV park, and temporary recreational camping events require prior approval by the city manager or designee.5 Camping cannot create a nuisance or violate city zoning laws.5

We could not confirm a Richmond rule specifically authorizing tiny-home occupancy; ask Richmond Planning how the proposed dwelling is classified and the Permit Office which construction standards apply.119 A manufactured home has a separate city placement/occupancy permit requirement, including permits, inspections, compliance findings and payment of fees before occupancy.12

What are the steps to building a home in Richmond?

  1. Ask Richmond Planning to confirm the parcel’s city jurisdiction, zoning district, allowed residential use and utility requirements before choosing a design.1126
  2. Resolve wastewater service: if proposing septic, ask Environmental Health to confirm the Richmond address’s permitting authority before arranging the required Texas septic approval.413
  3. Ask Richmond’s Code Official or designee, acting as Floodplain Administrator, whether the project needs city floodplain development approval.16
  4. Submit the city building permit application through the portal and obtain the required building permit before starting covered work.91
  5. Arrange city inspection requests through the portal and obtain the required certificate of occupancy before using the home.98

What should you check before buying land in Richmond?

For a parcel outside Richmond city limits, use the Fort Bend County guide: county residential development permits apply to qualifying construction in unincorporated areas, while Richmond has its own building permit requirements inside the city.171 Richmond’s floodplain development approval is administered by the city Code Official or designee, so ask that office about the proposed building site.16

Richmond regulates residential driveway width and front-yard driveway area; include the driveway in the site-layout discussion with Planning.18 We could not confirm the water-well permitting authority inside Richmond; ask Planning about allowed utility arrangements and the Permit Office about the proposed well before relying on an off-grid plan.69 Fort Bend County’s effective property tax rate is 2%, a county-level figure rather than a Richmond parcel tax quote.19

Watch-outs

  • Richmond’s city zoning still applies even though Fort Bend County has not adopted county zoning ordinances.23
  • The Richmond rear-yard camping defense requires an occupied main building and lasts no more than 48 hours; do not treat vacant land as an approved RV residence.5
  • Confirm septic jurisdiction for a Richmond address with Environmental Health before relying on Fort Bend County’s OSSF rules or any state exemption.413
