Bathroom permits in Johnston, explained
Johnston lists remodels, repairs, and plumbing, mechanical and electrical work as permit items. A bathroom that moves a drain or adds a circuit needs a building permit and a trade permit. The city says its list is not all-inclusive, so call before you start.
When a bathroom needs a permit
Johnston names remodels and repairs on its permit list. Plumbing, mechanical and electrical work are listed separately, and they use a Trade Permit Application. The Building Department says no list covers every case, so call 515-727-7778 if you are unsure about your job.
Licensed trades for plumbing and wiring
Iowa licenses plumbers, electricians and mechanical contractors, while general contractors register with DIAL. On a Busy Builders bathroom, licensed subcontractors we coordinate handle the plumbing, wiring and fan ductwork. One customer review credits our plumbing sub for a weekend faucet repair after a remodel.
Ventilation is mechanical work
Moving or adding a bath fan is mechanical work, which Johnston lists as a permit item. That work goes on the Trade Permit Application with the plumbing and electrical changes. Ask the Building Department how it wants the fan duct route shown on your plans.
Review, inspections and timing
Allow at least 7 working days for Johnston to review the application. All work is subject to inspection and approval by the Building Department or its designee. Submit by email, by mail or in person at City Hall, 6221 Merle Hay Road.
What bathrooms cost with us
We have quoted hall baths from about $3,000 to $5,000 for a light facelift. A large primary bath can reach about $60,000. A typical three-quarter or full bath that keeps the layout lands around $15,000 to $20,000. Final costs vary by scope, materials, complexity and location within our service area.
Why bathroom budgets grow
Our estimates are set up front. The most common reason a bathroom job grows is new scope added after that first estimate: extra wiring, moved plumbing, new lighting and finer details. Settling those choices before the permit goes in keeps the plan and the price steady.

- Our process
How Busy Builders builds your Johnston bathroom remodel
We set the bathroom estimate up front, then confirm with you what moves and what stays. If a drain, circuit or fan changes, the Johnston trade permit covers it, and licensed trades we coordinate do the work. We file the building permit with its site plan. Demolition waits for approval, and the city asks you to allow at least 7 working days.
Repeat customers are common in our reviews; one household hired us back for a full bathroom remodel. Busy Builders is a registered Iowa contractor with more than 1,285 projects finished since 2020.

- Frequently Asked Questions
FAQs About Bathroom Remodeling in Johnston, IA
How much does a bathroom remodel cost in Johnston?
Most full bathrooms we quote that keep the same layout land around $15,000 to $20,000. A light hall bath refresh can be $3,000 to $5,000. Moving plumbing and growing the scope push the number up, as high as about $60,000 for a large primary bath. Prices depend on scope, materials, complexity and where in our service area you live.
Do I need a permit to remodel a bathroom in Johnston?
In most cases, yes. Johnston lists remodels and repairs as permit items. Plumbing, mechanical and electrical work need their own permits on a Trade Permit Application. The city says its list is not all-inclusive, so a quick call to 515-727-7778 clears up gray areas.
How long will Johnston take to review my bathroom permit?
Johnston asks applicants to allow a minimum of 7 working days for permit review. Its permits page notes a review may run longer. Send the application with its site plan, and follow up if an emailed submission gets no confirmation within 24 hours.
Who does the plumbing and electrical on a Johnston bathroom?
Licensed plumbers and electricians. Iowa licenses those trades, and Johnston permits their work separately from the building permit. On our jobs, licensed subcontractors we coordinate handle it, and we schedule them around the rest of the remodel.
Does Johnston want a site plan for an indoor bathroom job?
Yes. The city’s application form says all permits require a site plan. It shows an aerial view, a north arrow, adjacent street names, measured property lines and the footprint of existing structures. We prepare it along with the rest of the application.
What makes a bathroom remodel cost more than planned?
Scope added after the estimate. In our experience, wiring, plumbing changes, lighting and finer details added mid-project are the most common reasons a bathroom grows. Deciding those early keeps the final price close to the first number.
