Yes. Litchfield Park requires a building permit to repair, remove, convert or replace any plumbing system, and a tenant space change also brings plan review, a certificate of occupancy and a business license. Commercial plumbing improvements are listed at 5 to 10 business days for review, and simple permits can be issued over the counter.
“Whenever you construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure, or if you repair, remove, convert or replace any electrical, mechanical or plumbing system, a building permit is required.”

A Litchfield Park business owner usually asks two questions: does this plumbing job need a permit, and how long until it can start. The city answers both on its Building Safety pages, with a time range for commercial plumbing work and a fee line that depends on the value of the job.
What does Litchfield Park say about commercial plumbing permits?
The Building Safety Q&A page states the rule: "Whenever you construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure, or if you repair, remove, convert or replace any electrical, mechanical or plumbing system, a building permit is required."
The same page gives the review times:
- Commercial tenant improvement: 5 to 10 business days.
- Commercial electrical, mechanical or plumbing improvement: 5 to 10 business days.
- Commercial remodels and additions: 5 to 10 business days.
- New commercial building shells: 15 to 20 business days.
- Simple permits: the page says permits that need no review can be issued over the counter.
The commercial submittal package asks for two copies of each item, and a tenant improvement needs a detailed floor plan with section details plus "Associated plans for Electrical, Plumbing and Mechanical." Applications go through the city's GovWell portal, where the city does a completeness review first and issues an invoice once a submittal is complete.
What do the key terms mean?
- Tenant improvement (TI). Work inside an existing tenant space. The submittal package treats it as part of the building construction plans.
- BOV. The fee schedule footer defines it: "BOV = Based on Valuation." The fee depends on the stated value of the work.
- Certificate of occupancy (CO). City Code 7-18 says it "is specific to the owner and use of the building or tenant space."
- Temporary certificate of occupancy. City Code 7-19 makes it valid for thirty calendar days unless an extension is requested and granted.
Who does this cover?
Anyone doing plumbing work on a commercial building or tenant space in Litchfield Park: the owner, the tenant and the contractor who pulls the permit.
One narrow carve-out exists in the Q&A page: "Clearing of stoppages and/or repair of leaks in pipes, valves or fixtures, provided such repairs do not involve or require the replacement and/or the rearrangement of the valves, pipes or fixtures." That line is the city's own text on work that does not need a permit, and it stops where replacement or rearranging starts.
Quick check: what does the work trigger?
| Situation | What the city's pages say | Where |
|---|---|---|
| Replace or convert a plumbing system | Building permit required | Q&A page |
| Clear a stoppage or fix a leak with no replacement or rearranging | Listed as work that does not need a permit | Q&A page |
| New restaurant or medical tenant improvement | TI fee line is BOV of $40 per sq. ft.; office or mercantile is BOV of $20 per sq. ft. | Fee schedule |
| New commercial plumbing | 15% of permit fee | Fee schedule |
| Commercial plumbing repair | Based on valuation (BOV) | Fee schedule |
| Plan review | 65% of calculated permit fee | Fee schedule |
| Commercial plumbing inspection | 15% of permit fee each | Fee schedule |
| Work started or completed without a permit | Double permit fee | Fee schedule |
| Inspection after business hours | $100 per hour, 2-hour minimum | Fee schedule |
| Re-inspection | $75 after the same 2 failures | Fee schedule |
| Change of owner or use in a commercial space | A new certificate of occupancy | Code 7-18 |
What does this look like in real life?
A dental office moving into a former retail suite. The tenant improvement carries plumbing for chairs and sinks. The review list shows 5 to 10 business days for a tenant improvement, and the plumbing plans go in with the floor plan. Before the doors open, the space needs a certificate of occupancy, which requires field inspections by building safety, engineering, fire safety, and planning and zoning, and a city business license.
A small repair. A shop owner has a leaking supply valve replaced. The leak-repair carve-out covers repairs that do not require replacement of the valves, pipes or fixtures. Replacing the valve falls outside it, so this job reads as a permit job, and a contractor can confirm with Building Safety before starting.
The edge case. The same business changes ownership without changing the use. Code 7-18 says a new certificate is needed if the ownership or the use of a commercial building or tenant space changes, so a sale alone can trigger one.
What should you do next?
- 1Decide whether the job is a plain stoppage or leak repair, or whether it replaces or rearranges pipes, valves or fixtures. Only the first is listed as exempt.
- 2Call Building Safety at 623-935-1066 or email building@litchfield-park.org. Office hours are 7:00 a.m. to 4:00 p.m., Monday through Friday.
- 3Create an account on the GovWell portal and submit the application with two copies of plans for anything beyond a simple permit.
- 4Request each inspection on the same line. An inspection called in before 3:00 p.m. is made the next business day.
- 5For a tenant space, get the business license and plan for the certificate of occupancy ($200 per building on the FY2027 schedule). A temporary certificate lets equipment and stock move in, and the code says it is not permission to do business.
HQ Plumbing & Air handles commercial plumbing repair, restaurant lateral jetting and domestic backflow work. Fire sprinklers and fire backflow are outside what we do.
What do people get wrong?
- Myth: a repair never needs a permit. The exemption covers stoppages and leaks only when nothing is replaced or rearranged.
- Myth: the permit fee is a flat number. For commercial plumbing the schedule uses a percentage of the permit fee or a valuation, not a flat price.
- Myth: a certificate of occupancy follows the building. Code 7-18 ties it to the owner and use.
- Myth: the fee schedule's date is clear. The FY2027 document has a cover that says effective 8/1/2026 and a footer that says Effective August 1, 2025, so confirm the current line with the city.
