Common Questions

Yes, the Los Angeles Department of Building and Safety (LADBS) requires a plumbing permit for any new drainage system installation. In 2026, the base plumbing permit starts at approximately $60, but with the mandatory 90% plan check fee and city surcharges, total permit costs typically range from $150 to $500.

Installing a new sump basin in a concrete basement floor requires jackhammering and excavation, which adds significantly to labor. In Los Angeles, this typically increases the total project cost by $500 to $1,200 compared to a simple replacement or a dirt floor installation.

For residential sump pump services, licensed journeyman plumbers in Los Angeles currently charge between $85 and $130 per hour. Master plumbers or emergency after-hours services can command rates as high as $225 per hour.

A straightforward replacement of an existing unit in an established basin takes 2 to 4 hours. However, a brand-new installation involving pit excavation and new discharge lines typically takes 8 to 10 hours of labor.
