Navigating Connecticut Permits in Renovations

Written by Kevin Ahern | Jan 2, 2026 7:15:00 PM

The permitting process is one of the most important parts of a home remodel. For many remodels, a permit is required for compliance with state and local laws. More importantly, permits help ensure that the work is done safely and correctly. For homeowners, the Connecticut permitting process can be a little overwhelming. Understanding the permitting process and what to expect during your remodel is important.

Keep in mind that good contractors always pull permits when required and are experienced with the permitting process. Hiring a reputable contractor helps ensure that your remodel will be permitted if required, and the work will be compliant when it's finished.

Why Are Permits Required?

A safe home must meet the minimum standards for safe construction. Pulling a permit ensures that your home is in compliance with state building codes for safe construction in Connecticut. Permitting officers provide oversight of major construction projects, checking for quality and adherence to building standards.

Why Are Permits Required for Some Projects but Not Others?

Minor projects have far less potential to impact the safety of your home. Therefore, many small repairs do not require a permit.

Which Projects Need Permits?

Typical projects that require a permit include:

  • Building an addition and miscellaneous structural work
  • New home construction
  • Electrical, plumbing, and mechanical work
  • Deck construction
  • Pool installation
  • Fireplace installation
  • Retaining wall construction

In many cases, there are nuances to which projects require permits and which do not. Small retaining walls under three feet, for example, may not require a permit - larger retaining walls do. Requirements can vary from one community to another, so if you're wondering whether your project requires a permit, contact your municipal building department.

How Does Permitting Work?

The permitting process is relatively standardized throughout the state of Connecticut, even if permitting requirements vary. Here's the process:

  1. The permit application and design specs are submitted to the municipal building department.
  2. The application is approved or denied. If the application is approved, the process moves forward to the next step. If the application is rejected, it must be amended and resubmitted.
  3. The building inspector inspects the work at a point midway through the project. During this visit, the inspector is looking for indications that the work is being completed in compliance with building codes.
  4. The building inspector inspects the work at the end when the project is finished. The inspector will certify that the work has been completed properly.
  5. The permit is stored on record at the building department office, so when you sell the house, this information can be referenced. Many home buyers check to see that permits were pulled for recent projects, to ensure the house they purchase is safe and compliant.

Does Getting a Permit Add Time to Your Remodel?

For many projects, the permit does not add extra time to the remodel. Most reputable contractors aren't available to start work immediately after the contract is signed anyway. The permit application is submitted around the same time that the materials are purchased. When the contractor is ready to begin, the application is already processed and approved.

If a permit does add time to the remodel, your contractor should communicate with you. The length of time it takes to process and approve a permit varies.

How Much Do Permits Cost?

Homeowners pay a set amount for every $1,000 of the anticipated remodel. For example, suppose a homeowner lives in a town where the cost of a permit is $20 per $1,000. If the anticipated cost of the remodel is $10,000, the permit would cost $200.

Permit costs in Connecticut range between $16 and $34 for every $1,000. To find out how much permits cost in your town, contact your municipal building department.

Will My Home Remodel Require Multiple Permits?

Typically, the general contractor will pull a general permit for the overall project, and subcontractors will obtain permits for electrical, plumbing, HVAC, etc. These permits are all connected to one project, but are also separate permits. When the permits are filed, they're found under the general contractor's permit.

Can a Permit Be Denied?

Yes, a permit can be denied. Typically, permits are denied when there is insufficient information. If a permit is denied, the building department may request more information. Your contractor should handle any revisions to the permit application.

Who Will Get the Permit: The Homeowner, or the Contractor?

Homeowners can submit requests for their permit, but when you work with Litchfield Builders, the permit is pulled for you. This ensures the permit application is properly filled out, and the application is submitted on time.

How Can I Find Out More Information About Permits In My Community?

Many communities have a municipal building department website where you can find out more information about permit requirements in your area. Look up your city government online to learn more about how to get a permit, what work is required to be permitted, and more. You may also find a permit application online.

You can learn more about the Connecticut State building code through the state of Connecticut's website.
