Appliance installation in Detroit: Plan the Hookup

Choose the installer around the connection work

Describe the appliance you are replacing, its fuel type, its location, and whether you want to move it. Send photos of the existing connections and the space around them. Have the installer review the new model’s installation instructions and identify work outside their scope before you compare quotes.

For plumbing work that requires a contractor permit, obtain the plumbing contractor’s license number and the supervising master plumber’s license number. Detroit requires both numbers on the application. The city also issues a registration certificate to properly licensed Michigan plumbing contractors. Record who will obtain the permit and supervise the work. [1]

Detroit requires mechanical permits for new or altered gas piping and exhaust systems. Contractors obtaining those permits must hold a valid Michigan mechanical license with classifications appropriate to the work and register with Detroit. Have the contractor identify the classification covering your proposed installation. [2]

Resolve permits before delivery day

Confirm the plumbing permit scope before treating a replacement as exempt. Detroit says plumbing work must wait until the enforcing agency issues a permit. Its stated repair exemption covers working parts of faucets or valves and clearing stoppages without altering existing piping or fixtures. Describe your proposed hookup to the Plumbing Division for a scope-specific answer. [1]

Put permit responsibility in the quote alongside the connection work. Discuss whether the contractor needs a rough inspection before closing walls or concealing piping. Detroit’s plumbing inspection guidance requires installers to leave work uncovered and accessible for applicable inspections. [1]

For a fuel conversion or an appliance move, have the contractor assess the electrical supply during the planning visit. Name the person responsible for any electrical work in your agreement. Have them confirm the permit scope with BSEED before you commit to a delivery date.

Plan separately for a gas-service modification

If you are adding gas appliances, discuss whether the project needs a DTE meter or service-line review. DTE asks customers to list existing gas appliances and planned additions, including dryers and stoves, and photograph the meter from about 15 feet away. DTE does not take responsibility for customer fuel-line work from the meter into the home; arrange that work with your contractor. [3]

Allow for the utility’s process if DTE needs to modify service. DTE states that its information review can take up to one week. If it needs an onsite review, that process can take up to three weeks. After receiving your signed quote and any required payment, DTE schedules service to occur within the following four to six weeks. These published windows concern service modifications, not appliance hookup times. [3]

Compare quotes and prepare the space

Give each bidder the same scope: disconnecting the old appliance, moving the new one into place, connection materials, installation, testing, haul-away, permits and inspections. Request separate amounts for proposed cabinet or utility changes. Agree on how the installer will obtain your approval for additional work before starting it.

Measure the appliance opening and the delivery route through doors, stairs and turns. Compare those measurements with the new model’s dimensions and required clearances. Clear access to shutoffs and connections. Confirm who supplies hoses, cords and other model-specific parts, and who removes packaging and the old appliance.

If you are choosing a dishwasher, compare capacity alongside dimensions. ENERGY STAR distinguishes standard models with at least eight place settings plus six serving pieces from compact models below that capacity. Use its water-use limits as a national product-selection reference, then check the model specifications to plan the opening and connections. [4]

Check operation and collect acceptance records

Have the installer demonstrate operation, explain the shutoffs and show you the completed connections. For plumbing final inspections, Detroit requires appliances and equipment to operate, remain free of defects or damage, and have leak-free water and waste connections. Keep the invoice, model information and permit records together. [1]

For permitted plumbing work, have the permit holder obtain inspection approval and request the Certificate of Acceptance. Detroit requires approval before it finalizes the permit. For mechanical work, the city says it mails the Certificate of Acceptance to the contractor of record after finalizing the permit. Obtain a copy for your records. [1] [2]

Frequently Asked Questions

Does replacing a dishwasher require a plumbing permit?

Confirm the exact scope with Detroit’s Plumbing Division. The city requires permits before plumbing work and describes an exemption for certain faucet or valve repairs and stoppage clearance without piping or fixture alterations. That wording does not establish a blanket exemption for dishwasher replacements. [1]

Will DTE install the gas line inside my home?

DTE says it is not responsible for customer fuel-line work from the meter into the building. Arrange that work with your contractor. For a service-modification request, DTE reviews meter and service-line sizing using your existing and planned gas appliances. [3]

Can I take out a homeowner mechanical permit for a hired installer?

Detroit’s mechanical guidance requires a single-family residence, proof that you live there or are about to occupy it, and that you perform all the work yourself. The city warns against obtaining a homeowner permit for work a contractor or handyman performs. Have the hired contractor obtain their required permit. [2]

How much should I budget for installation?

Request an itemized quote after the installer reviews your model and connections. Separate hookup labor, parts, utility alterations, permits, inspections and haul-away. Agree on a price for the described work and an approval process for any additions. The sources supporting this page do not establish a Detroit installation-price range.
