Permit takeaway

Hartford says applicants should determine whether planning and zoning or historic review is needed before applying for a building, mechanical, plumbing, sprinkler, or temporary structure permit.

Zoning and placement

Planning and zoning review is often the first step in the development process and is submitted through Hartford's Accela portal for zoning permits, site plan review, and special permits.

Building and trade review

Hartford permit applications may require drawings, technical specifications, workers compensation insurance, contractor licenses, authorization letters, and signed home improvement contracts.

Call before applying when

Call before applying if the project includes renovation walls, decks, roofing, windows, doors, sheds, signs, new construction, temporary tents, plumbing, mechanical, sprinkler, or historic district work.
