The City of Dubuque Inspection & Construction Services Division issues building permits for commercial and residential projects. Our building inspectors are responsible for examining all construction plans and documents to ensure all work meets minimum code requirements prior to the issuance of the permit. Our inspectors will perform field inspections throughout your project to ensure work is being done according to the submitted application and plans. Upon completion, our inspectors will issue a final completion letter or certificate of occupancy for each project.
2. Download the Plan Review Checklist, complete, save and submit with the application.
3. Inspection & Construction Services will perform a plan review of the submitted construction documents and will provide plan review notes and/or plan approval prior to permit issuance.
4. Permit applications for new construction projects must include a site plan for review and approval by the Planning and Zoning Department prior to permit issuance.
5. A plan review fee will be charged for all new construction, additions, remodels, and accessory buildings over 200 square feet in size.
6. All other general building permits being applied for can submit the residential building permit application along with a detailed work description of the project or work being done.
NOTE: By providing as much detail about your project as possible including product specifications when appropriate, the plan reviewer will be able to provide helpful feedback that could prevent potential code deficiencies that may be identified at the time of inspection.
7. In addition to a building permit, if the scope of work for your proposed project includes plumbing, mechanical, or electrical, a separate permit application must be submitted for each trade.
Building permit applications can be submitted online (link in 1a above), by mail, e-mail, or in person at the Inspection & Construction Services Division located at the Historic Federal Building, 350 W 6th St., Suite 312 (3rd floor) in the Housing & Community Development Department office.

As the owner-occupant of a detached single family dwelling, you are allowed to install fuel gas piping within your home. Such installations require permits and must pass all inspections. The following list of “dos and don’ts” are intended to help make the completed job easier, safe and code complying. These helpful comments do not preclude compliance with other significant aspects of the Dubuque Mechanical Code – Fuel Gas Piping requirements.
Do:
Use Schedule 40 black steel piping with malleable iron screwed fittings (no cast iron). Flexible Corrugated Stainless Steel Tubing (CSST) will also be allowed as per the manufacturer’s guidelines.
Use an approved pipe thread compound applied to the male threads only (keep at least 2 threads back from end of pipe).
Incorporate drip legs at all appliance connections. For mobile home gas piping, care must be exercised so that such drip legs are not located in a freezable area
(any water vapor or condensate that may be entrained in the gas line will settle in such legs causing pipe or fittings to rupture if it freezes). Outside or unheated areas are prohibited locations for gas piping drip legs.
Incorporate an approved gas shut-off valve within three feet of the appliance served and a malleable ground joint union downstream of the valve to enable replacement of the appliance. In lieu of the ground joint union, an AGA approved flexible appliance connector may be used (flexible connector cannot penetrate appliance casing).
Double check your piping layout for proper sizing based on the Dubuque Mechanical Code pipe sizing method.
Provide an air test (at least 15 psi) on all newly installed piping. Test pressure must be maintained without loss of pressure for at least 15 minutes and observed by an inspector. (Gauge readout dial must not be more than 30 psi). If gas pressure is 2 pounds or higher, call Building Safety Department for test requirements.
Provide an approved mobile home flexible connector between service outlet and trailer when piping gas to a mobile home.
All gas piping systems are required to be bonded according to the National Electrical Code (NEC), National Fire Protection Association (NFPA) 70.
Call the Building Safety Department at 563-589-4150 with any questions, when in doubt, or to set up an inspection.
Don't
Run gas piping underground, under or embedded in concrete. If gas piping must be run underground, contact the Building Safety Department for code requirements and testing.
Incorporate ground joint unions anywhere in the piping system except at the appliance or at the meter connection.
Subject any appliance gas control valve, regulator valve or the gas meter to the system piping are test pressure (such devices will be damaged if subjected to the required 15 psi test pressure).
Conceal any portion of the piping until an inspector has seen it.
Connect bond wire to any portion of CSST.
Bear in mind that the permit holder is solely responsible for the use of proper materials; correct pip sizing; proper installation of equipment, piping, valves and controls; and pressure testing of the gas piping system as required by the Building Safety Department. By obtaining a permit, the permit holder is stating that he or she is competent and knowledgeable to the degree required. While the Building Safety Department will attempt to help you, we cannot design your installation. If you have any doubts, consult a qualified licensed installer.
Any pool, spa, or hot tub requires a building permit if the structure can hold more than 24 inches in depth of water and must be completely surrounded by a fence or barrier. Exception: Spas or hot tubs with a safety cover that complies with ASTM F 1346 shall be exempt from the provisions of this section.
General code requirements include:
A fence or barrier at least 48 inches high must be installed restricting access to the pool. It must be measured from the finished ground level on the side of the fence or barrier away from the pool.
Gates must open away from the water and be self-closing and self-latching from an open position of 6 inches from the gate post.
Any locking and/or latching device is required to be a minimum 54 inches above grade and the release mechanism is to be located on the pool side of the gate.
An existing pool enclosure shall not be removed, replaced or changed in a manner that reduces its effectiveness as a safety barrier.
Swimming pools shall be maintained in a clean and sanitary condition, and in good repair.
The Permit Fee for swimming pools that don’t require a structural footing or foundation inspection is $46. For all swimming pools that require City Inspection to inspect footings or foundation walls for structural purposes an additional permit fee will be established based on the value of work for the construction of the footing and foundation wall.
Electrical Permits are required if new electrical is ran to provide power to the pool systems or outlets. Please note that National Electrical Code Section 400.8(1) prohibits the use of extension cords as a replacement for permanent wiring.

Commercial Building Permit Applications are Required for:
All Non-Residential Structures, including all multi-family residential buildings with three or more dwelling units.
NOTE: The Planning and Zoning Department needs to approve all site plans prior to building permit issuance
Application Requirements
New construction, additions or alterations, and interior remodel projects require construction plans to be submitted with the permit application.
All new construction projects are required to submit a site plan for review and approval by the Planning and Zoning Department prior to permit issuance.
A plan review fee is charged for all new construction, additions, remodels, and accessory building over 200 square feet. The plan review fee is 20% of the permit fee.
All signs require a separate permanent sign permit application or temporary sign permit application, reviewed for approval by the Planning and Zoning Department prior to permit issuance. Signs applications should be submitted at the same time your site plan or building plans are submitted to make sure approval is granted prior to moving forward with your project. The City of Dubuque requires sign contractors to obtain an annual license from the Inspection & Construction Services Division.
