Sewer Line Installation Pro Costs

Permits and Regulations

If the project is in the right-of-way of Maricopa County sidewalks or streets, you’ll need to get a permit from the Maricopa County Department of Transportation (MCDOT). These right-of-way permits cost $150 for residential projects.
Labor
Labor is a large portion of the total costs because the job is time- and labor-intensive, and pros charge between $25 and $200 per linear foot. Unlike some other home improvement projects, this one requires hiring a skilled pro with experience taking on these complex plumbing projects.
Does Sewer Line Installation Increase Home Value?

Otherwise, you can expect your home’s asking price to be lower due to the high repair costs that the new buyer will be responsible for.
