How long it takes to get a project approved in Connecticut
Most projects in Connecticut start with the town. The planning and zoning commission and the zoning board of appeals must approve the land use, and the town building department issues the building permit.
Below are the five phases of a project in Connecticut, who approves it and how long the path to a building permit usually takes, worked out by ShovelCue from the review times it holds for Connecticut.
How long to a building permit
- New multifamily building12 to 14 months
- Retail tenant fit outAbout 3 months
- Addition to a single family home3 to 6 months
These are estimates from typical review times, not promises. They run from the start of due diligence to the building permit. Your town, your site and how complete your drawings are can move them.

- Zoning Verification / Zoning DeterminationWord from the town on what the zoning allows.
- Topographic SurveyThe ground levels the site design starts from.
Entitlements

The five phases in Connecticut
- Due DiligenceBefore you commit to a site in Connecticut, you check the survey, the soil, the flood risk and what the zoning allows.
- EntitlementsThe planning and zoning commission and the zoning board of appeals must approve the site plan and any zoning relief.
- Pre-constructionThe drawings go to the town building department for the building permit and the trade permits, while the soil conservation district, the state environmental agency and the utility companies sign off on the parts of the site they control.
- ConstructionThe town building department inspects the work in stages with the local fire official, and each stage must pass before it is covered up.
- CloseoutThe last inspections lead to the certificate that lets people move in, and in Connecticut the state labor or safety office checks equipment such as elevators before it runs. Then the owner gets the warranties, the manuals and the record drawings.

Questions
How long does it take to get a building permit in Connecticut?
ShovelCue estimates 12 to 14 months for a new multifamily building, from the start of due diligence to the building permit. A retail tenant fit out takes about 3 months, and an addition to a single family home takes 3 to 6 months. Your town and your site can change this.
Who approves a construction project in Connecticut?
Most approvals come from the town, through the planning and zoning commission and the zoning board of appeals, then the town building department. Depending on the site, 6 state agencies may also sign off, such as the state environmental agency and the state transportation department. The utility companies approve new service.
Why is the estimate a range?
The short end counts only what the rules require for every project of that type. The long end adds what is usual for that kind of project. In Connecticut the gap is widest for an addition to a single family home, about 3 months.
Does a small job in Connecticut need state approvals?
Usually not. A tenant fit out or a small addition is mostly a matter for the town building department. State approvals come in when you build new, disturb ground or work near water or a state road.
