Michigan Basement Waterproofing Rules for Lansing, MI Homeowners
A basement job in Lansing, Michigan's capital city, can touch a state trade license, plumbing law, a written agreement, a possible cancel window, local permits and the City's sewer steps. Each section names an office that can confirm it.
The Basics
This is a summary of public law, not legal advice.
- Permits follow the address. The City and each nearby city or township run separate permit offices.
- Check the license yourself. Michigan licenses basement waterproofing through LARA, and its records are public.
- Backups are a sewer matter. In the City of Lansing, a floor-drain backup goes to the City.
Verifying a Contractor
Michigan has no stand-alone waterproofing license. Through the Michigan Occupational Code, Article 24 (MCL 339.2401 and following), LARA licenses residential builders and maintenance and alteration contractors; MCL 339.2404(3) lists "waterproofing a basement" among the second group's trades, and a builder license covers it too. No City or town contractor license turned up.
Get the number first: the Attorney General suggests asking for the 10-digit residential builder license number, and LARA calls a contractor unable to supply one "a red flag." Search it on LARA's online license lookup or reach builder licensing at 517-241-9316. A license is a state credential you confirm, not a promise about workmanship.
Under Michigan's administrative rules for builders and contractors (R 338.1532 and R 338.1533), a licensee must print its licensed name, license number and real business address in every ad. This site names no contractor; whoever gets in touch should show you all three, plus insurance certificates, recent local customers and a visitable address.
The Skilled Trades Regulation Act's plumbing provisions (MCL 339.6103 and 339.6107) count sanitary and storm drainage as plumbing, done only by licensed master or journey plumbers once the responsible plumbing contractor has a permit. Sump hookups to a drain, backflow valves, ejectors and lateral work belong to a licensed plumbing contractor; owners may plumb their own single-family house with a permit.
Owners doing their own work need no builder license, and a job under $600 in all can be exempt unless split up or part of a bigger one. Unlicensed work is a misdemeanor, fined $5,000 to $25,000 on a first offense, and that contractor can't sue for payment.
Article 24 also marks this site's limits: its builder includes anyone paid who "offers to undertake, or purports to have the capacity to undertake" work on a house; its salesperson is a licensee's paid agent working to "solicit for" it or "obtain … a contract or commitment." Basement Waterproofing Lansing MI, a referral and advertising service with no Michigan builder, maintenance and alteration or plumbing license, does neither: it bids on nothing, visits no homes, takes no deposits and vouches for no one. One independent contractor gets your request to be contacted and may pay a flat advertising fee, waived during a free trial.

Protecting Yourself on Paper
R 338.1533 wants the deal, and each change, written and signed by both of you, stating the price, which work and how much, and which materials at what grade. Keep a copy.
- Dates and stages. Start and finish, with payments tied to progress; LARA advises against paying everything up front.
- A measured scope. Feet of drain, pump details and the outdoor discharge point.
- Permits by name. Each permit, who pulls it, and inspections passed before the last payment.
- The warranty, written out. Coverage, length, and whether it stays with the house if you sell.
Written lien waivers before the final payment are a sensible general precaution.
Cooling-Off Rules
Generally, Michigan's Home Solicitation Sales Act (MCL 445.111 and 445.112) allows a buyer to cancel a sale over $25 solicited and signed at the buyer's home, until midnight of the third business day after signing; only a real emergency, with a separate handwritten, dated and signed statement, waives that. Whether it reaches a job you first asked about online is unsettled, so it's a right you may have. Your contract should explain how to cancel. A written cancellation, with a copy kept, is the sensible route.
The Michigan Consumer Protection Act (MCL 445.903) outlaws confusion over a service's source, sponsorship, approval or certification, invented connections and hidden material facts, so this site discloses its advertising and claims no agency ties. Under MCL 500.1222, Michigan's adjuster licensing law, handling a loss under someone's insurance policy takes a license; this site handles none, so ask your insurer or agent. Contractor complaints: the Michigan Attorney General's Consumer Protection team, 517-335-7599 or toll-free 877-765-8388.
Programs Before You Pay
The one program here is the City of Lansing's. Its Basement Backup Protection Program (B2P2) applies only inside City limits, not to every Lansing mailing address, and only to plumber work with a permit and a City inspection. Check its current terms and apply to the City directly before work begins; this site has no part in it.
The City's page offers basement sewer backup assistance to qualifying owners. Local news outlets describe partial reimbursement for City property owners who add a backflow-prevention valve or sump pump system, after hiring a licensed plumber, passing the permit and inspection, and paying the bill; broken laterals and root problems aren't covered. Before planning around it, ask the Public Service Department whether money remains.
That department runs Lansing's sewers; its Operations and Maintenance Division lists (517) 483-4161 as a 24-hour help line (911 for emergencies). BWL bills may show a sewer charge, but backups go to the City. The City's flooding guide gives the street main to the City and the house lateral to the owner, whose repairs need a licensed plumbing contractor and a permit. Some older parts of the city had combined sewers, which the City has been separating since 1992 with state clean-water loans, per the U.S. EPA.
If a City sewer seems behind a backup, the City's guide allows 45 days from discovering the damage to turn in the City's claim form (Claims Coordinator, (517) 483-4818). Public Act 222 of 2001 (MCL 691.1419) generally calls for written notice to the sewer's operating agency within 45 days of discovery.
County drains and drainage districts are the Ingham County Drain Commissioner's, separate from laterals and City sewers. River floods, like April 1975's (USGS) or the Grand's February 2018 rise (WKAR), are history, not programs. No program turned up in East Lansing, MI, Okemos, MI (Meridian Township), Holt, MI (Delhi Township), Grand Ledge, MI or DeWitt, MI.
Before paying anyone: report backups to the right office, read your policy, confirm B2P2's terms before a plumber starts, and get a signed written agreement.
Permits and Local Rules
City of Lansing permits come from the Building Safety Office, 517-483-4355. In the City's words, "Building Permits are required prior to the beginning of construction or remodeling," and backflow preventers appear among its plumbing permits. Sewer-line work or a backflow valve takes a plumbing permit from a licensed plumbing contractor; digging or structural repair may call for a building permit first; whether a drain-and-sump scope does is the contractor's question for the office. Some neighboring townships use Lansing mailing addresses, so ask the office whether yours is a City address.
- Holt, MI. Delhi Township Community Development, 517-694-8281, 2074 Aurelius Road, requires building or trade permits for additions and alterations, and a permit before excavation.
- DeWitt, MI. City Hall, (517) 669-2441, 414 E. Main Street; sumps, sewage ejectors and the house's sanitary sewer hookup all appear on its plumbing permit form.
- Okemos, MI. 5151 Marsh Road houses Meridian Township's Community Planning & Development (517-853-4000), whose Building Division issues plumbing permits.
- East Lansing, MI. Ask the City of East Lansing's building office first.
- Grand Ledge, MI. Ask the City of Grand Ledge.

Rules Questions, Answered
Does B2P2 help pay for drain tile or crack repair?
Nothing read about it says so. As described, it concerns backflow-prevention valves and sump pump systems a licensed plumber installs under a permit at City of Lansing addresses. Ask the Public Service Department first.

Ask About Your Job
Rules tell you what to ask, not what a basement needs. Send the short request form, and the one independent contractor who receives it gets in touch, plans any visit on its own and writes out its scope and price. For rough numbers first, use the cost calculator or the wet basement checker.
