Indiana Basement Waterproofing Rules for Indianapolis, IN Homeowners
Indiana leaves contractor licensing to local governments, sets firm rules for home improvement contracts and keeps plumbing under a state license. This page sorts out those rules for homeowners in Indianapolis, Indiana and five nearby towns, with each office's public number. This is a summary of public law, not legal advice.
What Matters Most
- Above $150, put it on paper. The contract is written out, and the contractor signs it before you do.
- Licensing is local. With no statewide contractor license, the rules depend on where the house stands.
- Pipes mean plumbing. Sump tie-ins, backwater valves and laterals are plumbing or sewer work in Indiana.
- Sewers have different operators. Citizens Energy Group serves Indianapolis; the five towns run their own.
Contractor Licensing in Indianapolis
Indiana has no statewide license for general or home improvement contractors. The Attorney General's office says requirements "vary from community to community." In Indianapolis, ask the contractor which local license or registration covers your job, then check with the City's Department of Business and Neighborhood Services, (317) 327-8700.
Beech Grove has general and plumbing contractors register with its Clerk-Treasurer, and a general contractor files a bond and a certificate of insurance naming the City. Speedway gives mechanical permits only to licensed electricians, plumbers or HVAC specialists.
Plumbing is the trade Indiana licenses itself. Its plumbing law (IC 25-28.5) counts storm and sanitary drainage and sewer piping as plumbing as far as the property line, and nobody may work as a plumbing contractor without an Indiana Plumbing Commission license. The law also lets sewer, excavation and utility contractors work on lines beyond the foundation walls, and an owner-occupant of a building with up to eight units may do its own.
Indiana's Home Improvement Contracts Act (IC 24-5-11) treats a person who "engages in or solicits" these contracts as a supplier, whether or not that person ever meets the homeowner. So Basement Waterproofing Indianapolis IN invites only a request to be contacted. It is an advertising and referral service, no kind of contractor: it quotes nothing, handles no contracts, names no contractor and vouches for no one. The one independent contractor that gets each request may pay the site a flat advertising fee; you pay nothing and get nothing.

Contract Basics
The Act counts nearly any change to a home as an improvement, indoors or out, from repairs to replacements to rebuilding. Once an agreement for that work goes past $150, spoken or written, its contract rules apply. You get the finished contract before you sign, already signed by the contractor on every term, and no down payment can be demanded until that signature is on it.
- Who and where. Your name and address; the contractor's name, address and email; and who deals with problems, with a name, number and email.
- Dates. When it was offered, any deadline to accept, and rough start and finish dates, with anything that could shift them.
- The work. A reasonably detailed description: drain length, pump details, the sump's discharge point and materials.
- The price. Stated plainly.
- Outside help. Whether a subcontractor or supplier not named in the contract will provide labor or materials.
The Attorney General's office adds two habits: record every change in a signed, written change order, and pay no more than a third up front, which is advice rather than a legal cap. Get warranty terms on paper. Breaking the Act is a deceptive act the Attorney General or the homeowner can pursue, and the state's home improvement fraud chapter calls a contract unconscionable when its price runs unreasonably past the work's fair market value (IC 35-43-6-8).
Changing Your Mind After Signing
Two state cancellation rules can apply. The Home Consumer Transactions Act (IC 24-5-10) reaches a sale you didn't seek out that grew from a seller's direct contact away from its business. Your notice is due by midnight of the third business day, counted from whichever came last: the final agreement or the written notice of your rights. A second rule (IC 24-4.5-2-501 and -502) covers credit sales pitched and agreed to in person at your home, following the federal cooling-off rule.
Whether either covers a contact you asked for online is unsettled, so you may have three business days to back out of a contract signed at home, and the contract should say how.
The Deceptive Consumer Sales Act (IC 24-5-0.5) forbids claiming a sponsorship, approval or affiliation a business lacks, or misstating when work will be finished. Complaints go to the Attorney General's Consumer Protection Division, 1-800-382-5516 or 317-232-6330.
City Programs That Can Help
The research behind this page found no City or utility repair program for homeowners, so these are Citizens Energy Group's and the City's ordinary services. Citizens has run the wastewater utility since 2011. Marion County's system is combined, and by Citizens' account a quarter inch of rain can be enough to start overflows. Its DigIndy tunnels (28 miles, 18 feet across, about 250 feet deep), finished in 2025, aim to keep at least 95% of overflows out of the rivers, but they don't stop basement backups: Broad Ripple had some in April 2026.
- Backups. Report them to Citizens at (317) 924-3311. If the public sewer is clear, the problem is private: Citizens refers owners to a licensed plumber, and cleanup on the lot is the resident's.
- Clear water. Citizens cites state regulators' ban on clear-water discharges: sumps empty outdoors or to a storm sewer, downspouts at least three feet out. It mails a repair letter when it finds one.
- Backwater valves. Citizens suggests one for homes with basement fixtures, judged by a licensed plumber; a City permit and inspection may apply, (317) 327-8700.
- The lateral. The owner generally maintains the house line, and Citizens decides what sits in its easement (in a 2025 case it fixed only that part). Permits go through Citizens online; questions, 317-927-4444.
Most homeowner policies skip sewer backups without an endorsement, typically $40 to $160 a year, Citizens says; ask your insurer. Citizens describes its own damage-claim process on its sewer back-ups page. Other City requests go to the Mayor's Action Center, 317-327-4622.
Town addresses fall outside all of this: Beech Grove Sewage Works, Speedway's plant on Eagle Creek, Carmel Utilities (most of Carmel), Noblesville Utilities and the City of Greenwood serve their own.
Permits and Local Rules
In Indianapolis, foundation, excavation and structural repair usually require a City permit, while plumbing and sewer jobs get their own permits from a licensed plumbing contractor; the contractor confirms with the City what applies. Ask (317) 327-8700 about inside drain tile or a sump draining to the yard. Beech Grove and Speedway lie within Marion County but are excluded from the consolidated city, and each town issues its own permits.
- Carmel, IN. Building & Code Services, 317-571-2444.
- Noblesville, IN. Planning & Development, 16 S. 10th St, 317-776-6325, through the online Citizen Permit Portal.
- Beech Grove, IN. Building Commissioner, 317-509-9236; Clerk-Treasurer, 806 Main St, 317-788-4977 ext. 5100. Improvement Location Permits are filed with Indianapolis, (317) 327-8700.
- Greenwood, IN. Building Commissioner, 300 S. Madison Ave, 317-887-5230.
- Speedway, IN. Clerk/Treasurer's Office, 5300 Crawfordsville Rd, (317) 246-4111; Building Commissioner, (317) 246-4122.

Legal Questions, Plainly
Does Indiana make a waterproofing contractor hold a state license?
No. Indiana leaves contractor licensing to cities and towns, so ask the contractor which local license or registration applies at your address and confirm it with the permit office ((317) 327-8700 in Indianapolis). Plumbing differs: it calls for a plumbing contractor holding an Indiana Plumbing Commission license.
Can a contractor ask for money before I sign?
On a job over $150, the contractor signs every term first and can't require a down payment before that. After both signatures, the Attorney General's office suggests a deposit of a third or less.
