Permit and Inspection Services

Our Mission

To maintain and enhance safety, property values, and quality of life in Duncanville.

To this end, the city has adopted ordinances and health and building codes that set standards for the construction, repair, maintenance, and upkeep of commercial and residential properties, and for the safe operation of food service establishments in the city.


The thrust of the department's work is fivefold:

  1. To promote construction methods that provide for the safety of occupants and that are consistent with best practices adopted by other municipalities in this area
  2. To monitor the operation of restaurants and other food service establishments in the city as a means of preventing outbreaks of food-borne illness
  3. To prevent the deterioration of property
  4. To abate dangers to public health and safety
  5. To correct nuisances as defined by ordinance


There are many important reasons to obtain building permits and to have inspections performed for your construction project.

Protects property values

Your home is typically your largest investment. If your construction project does not comply with the building codes, your investment could lose value. If others in your neighborhood make unsafe or substandard changes to their homes, it could lower the resale values for the entire community.

Saves Money

Homeowners insurance policies may not pay for damages caused by work done without permits and inspections.

Makes Selling Property Easier

Listing associations require owners to disclose any home improvements or repairs and whether permits were obtained. Many financial institutions will not finance a purchase without proof of a final inspection. If you decide to sell a home or building that has had modifications without a permit, you may be required to tear down the addition, leave it unoccupied or do costly repairs.

Improves safety

Your permit allows the building department to inspect for potential hazards and unsafe construction. By ensuring your project meets the minimum building code standards of safety, the building department can reduce the risk of fire, structural collapse and other issues that might result in costly repairs, injuries and even death. Inspections complement the contractor’s experience and act as a system of checks and balances that can result in a safer project.

 It’s the Law

Permits are required by ordinance. Work without a permit may be subject to removal or other costly remedies.

Tips For Hiring Contractors

  • Hire only licensed contractors
  • Get at least 3 bids.
  • Get 3 references and ask to see a project.
  • Get it in writing, but before you sign the contract, make sure you completely understand.
  • NEVER pay for a project in advance. You should be wary of any contractor asking for a total payment up front prior to any work being started. A small retainer fee or payment for necessary materials may be appropriate. Do not make final payment until you have received a final inspection approval.
  • ALWAYS use licensed contractors. Insist on seeing evidence of a current state license. The following trades require a state license:
    • Electricians
    • Plumbers
    • Air Conditioning Contractors
    • Irrigation Contractors
  • Contractors must be registered with the City of Duncanville before doing work. Verify that the contractor applies for the required permits. Before your project begins, insist on seeing the permit. During your project, monitor your contractor’s inspection records. This will protect you from being responsible for code violations and ensure project completion. Be especially wary of contractors suggesting you obtain permits for their work. If you obtain the permit for a contractor, you will be responsible for their work being done and not the contractor. Contractors may do this purposefully to relieve them of responsibility for the construction project.
    • If you obtain a “homeowner” permit, you are the responsible party of record for the permit. If your work is being performed by a contractor, you may protect yourself from possible liability if the contractor applies for the proper permit in his or her name.
    • If you plan to do your own work, electricians, plumbers, and HVAC contractors must validate onto the building permit before they begin work.
    • It would benefit you to hire a licensed contractor to perform the mechanical, electrical, and plumbing work. However, if you plan to do your own electrical, plumbing or HVAC work, you must be the one performing the work. You can- not have someone else do the work for you.
    • Unlicensed contractors often request the homeowner to obtain a “homeowner” permit this is illegal and could be dangerous. The unlicensed contractor may not have the skill and experience to properly perform the work you are paying them to do.
    • Permits are valid for six months from the date the permit is issued, an extension can be requested in writing to the Building Official
