Carmel's patio permit, in plain words
Carmel's permit portal now lists "Residential Patio Over 120 Square Feet" as its own permit type, required as of April 27, 2026. A 120-square-foot patio is only about 10 by 12 feet, so most new patios will need one. The application asks for:
- A site plan showing where the patio goes.
- A foundation plan showing the location, width and depth of any footings.
- Approval from your HOA.
Fees are ten cents per square foot for filing and review, plus $100 per required inspection and $100 for the certificate of occupancy. Work follows the 2020 Indiana Residential Code. We'll lay out the patio and any sitting-wall footings so the drawings are straightforward, and you'll want to start the HOA request early because it's part of the city application.
Driveways: the 12-to-20-foot rule
Carmel's standard residential driveway is at least 12 feet and no more than 20 feet wide where it meets the right-of-way at the street. Each property gets one access point, and a new or extra curb cut needs approval from the Board of Public Works and Safety. Any work in the city right-of-way needs a right-of-way permit through Engineering, with a bond starting at $5,000, and a driveway that crosses an easement needs a Consent to Encroach. So a driveway widening in Carmel usually flares out on your lot and stays within the width limit at the curb. The same Consent to Encroach applies to retaining walls or other improvements placed in an easement.
Pool decks in Carmel
New pools and spas in Carmel carry a $500 filing fee plus 20 cents per square foot of pool and deck area, with a site plan showing the pool, equipment and deck relative to property lines and easements, and HOA approval. For an existing pool, the question is usually whether the deck can be resurfaced or needs replacing. The city also asks that pool water not be drained straight into the storm system.
Older Carmel and newer Carmel
Carmel's housing spans more decades than its neighbors. The median home was built in 1998, but about a quarter of homes date to the 1970s and 1980s. Those older lots tend to have original walks, stoops and patios at the end of their life, while the 1990s-and-later subdivisions have the builder patios and pool decks people want to upsize. The Village of West Clay, a 719-acre New Urbanist neighborhood between Ditch and Towne roads, has its own architectural styles, from Federal to Tudor, and a porch floor or front walk there has to look right with the house.
Fire pits in Carmel
Carmel bans open burning except outdoor gas grills and certain campfires. A campfire has to be at least 25 feet from combustibles and 100 feet from a power line, burn only untreated wood or commercial fire starters, and can only burn when the wind is between 5 and 15 mph. A ground fire is limited to 3 by 3 by 2 feet inside a stone border; a container or a city-approved fire pit can be up to 5 by 5 by 5 feet. Violations carry fines up to $500.
