Do you need a building permit in Westminster, MD?

For a Westminster building permit application, the city directs applicants to the Carroll County Office of Permits and Inspections at 225 North Center Street.1 Westminster’s Zoning Administrator reviews and processes building permits and determines building permit fees.3 New homes in Westminster require inspections throughout construction, coordinated with Carroll County.2 Before preparing plans, ask the city about zoning approval and ask the county application counter which building permit documents and inspection stages apply to your proposed work.31

Does Westminster have zoning, and how do you check setbacks?

Westminster has its own zoning ordinance, administered by the City Zoning Administrator.4 The city publishes the zoning ordinance and an interactive zoning map, so start with the parcel’s city zoning district rather than a county district.7 We could not confirm Westminster’s district-specific minimum lot size, minimum dwelling size, setbacks, lot coverage or building height requirements; ask the City Zoning Administrator to identify the applicable standards before choosing a house plan.3 For land outside city limits, use the Carroll County guide for the county’s unincorporated-area zoning answer.9

How do sewer connections and septic permits work in Westminster?

Westminster requires properties used for occupancy within the city’s public sewer service area to connect to public sewer within 90 days after official notice, at the owner’s expense.6 The service area follows the County Water and Sewer Master Plan, and a City sewer permit is required before connection.6 Westminster generally prohibits private septic tanks, privies and other sewage-disposal facilities in the sewer service area or areas under city jurisdiction, subject to ordinance exceptions.10 For a new Westminster home that needs septic, obtain the Health Department septic permit; city zoning approval does not replace that approval.54 Carroll County Health Department requires satisfactory final inspection of installed or modified septic systems for the applicable use-and-occupancy approval.11

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

We could not confirm Westminster’s rules for residential RV occupancy, temporary camping, tiny-home occupancy or manufactured-home placement; ask the City Zoning Administrator about the proposed use and parcel.3 A floodplain provision concerning recreational vehicles does not settle citywide residential RV permission: Westminster’s floodplain chapter has separate provisions for recreational vehicles and other structures in designated flood-hazard areas.12 A small dwelling also needs a sanitation plan consistent with Westminster’s sewer connection rules and restrictions on private sewage disposal.610 Ask the city for the use classification and zoning approval before purchasing an RV or ordering a tiny home for permanent occupancy.3

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

  1. Ask Westminster’s Zoning Administrator to confirm the parcel’s district, proposed residential use and city zoning review requirements.3
  2. Establish whether the parcel is in the city’s public sewer service area; obtain the City sewer permit before a sewer connection, or obtain the Health Department septic permit for a new home needing septic.65
  3. Submit the building permit application through the Carroll County office and coordinate Westminster’s building permit review and project-specific fees.13
  4. Arrange the required construction inspections, and ask the reviewing offices which use-and-occupancy certificate applies before moving in.213

What should you check before buying land in Westminster?

Ask Westminster’s Zoning Administrator about floodplain review before committing to a building site: city floodplain permits apply to development in designated flood-hazard areas.12 Maryland also requires a state permit for construction in wetlands and floodplains, so local building permit approval may not complete the approvals needed for the site.14 For private water, Maryland requires a well construction permit and limits potable wells on properties already connected to a community water supply unless authorized by the Department.8 For an entrance involving state highway right-of-way, coordinate a residential driveway access permit with the applicable MDOT SHA district office.15 We could not confirm Westminster’s separate local driveway-access rule; ask the city before designing the entrance.3

Watch-outs

  • Westminster’s sewer service-area rules can prevent a private septic or privy plan even where city zoning permits the dwelling.610
  • Westminster charges development fees for new and expanded projects; ask the City Zoning Administrator for the fees applicable to your project.1
  • Maryland’s owner-performed home-improvement exception concerns contractor license information on the permit; it does not waive the building permit itself or establish a new-home exemption.16
