What changed in Des Plaines’ construction-code references for 2026 projects?

Des Plaines’ building page says the City Council adopted updated construction codes in December 2025, effective January 1, 2026. It directs applicants to its digital Customer Self Service Portal for permits and contractor registration, with project-specific checklists. Buyers planning work should use the current City page and amendments when discussing designs, rather than an old permit packet or a prior renovation’s code edition. The page contains mixed energy-code references, so the exact energy provisions should be confirmed with staff for the application date.

How do I check a Des Plaines parcel’s zoning before proposing a different use?

Des Plaines’ Planning and Zoning page provides both an interactive zoning map and a downloadable map, together with the local zoning code. It also identifies site-plan review resources and the zoning contact for questions. A buyer considering a home-based use, addition or other change should locate the correct parcel and compare the proposed activity with the applicable district rules. Ask Planning and Zoning whether additional review is needed; the map identifies a starting classification rather than permission for every use or building configuration.

Local research · Seller questions

What must a Des Plaines seller clear before a transfer or exemption stamp issues?

Des Plaines applies its transfer tax to title or beneficial-interest transfers within corporate limits and requires city fees, fines and water balances paid before either type of stamp issues. Provide Finance the property and proposed deed details early, reconcile the balances, and use its current application guidance for the transaction rather than treating a tax exemption as account clearance.

Does a Des Plaines mailing address establish the city's transfer-tax applicability?

No. Des Plaines’s current page distinguishes incorporated property from unincorporated addresses and specifically excepts 9601 Golf Road from its general unincorporated treatment. Give Finance the exact parcel and transfer details before choosing the taxable or exemption route. Keep its determination with the closing file; a postal city label cannot resolve that named jurisdictional distinction.

Does Des Plaines' removal of city stickers also remove commuter-parking requirements?

No. Des Plaines Finance says the city-sticker program ended in July 2020, but a permit may still be required in Metra lots or downtown garages. Contact Parking about the specific facility, availability and intended use before choosing a commuting arrangement. Separate the vehicle-sticker rule from the parking permit needed for the station or garage.

Who maintains a Des Plaines sewer lateral beneath the street?

Des Plaines assigns ownership and maintenance of the sewer lateral from the house to the main to the property owner, including the public right-of-way segment. Identify the actual defective segment during inspection and obtain a repair scope. The pipe’s location under public pavement does not make its repair automatically a City expense.

What Des Plaines check should precede private sewer repair after a backup?

Des Plaines directs homeowners first to Public Works to inspect the sewer main and clear any main blockage. The City does not televise the homeowner’s lateral. If the main is clear, arrange a private contractor assessment and contact the Plumbing Inspector for a suspected right-of-way defect before assuming reimbursement is available.

Does every Des Plaines sewer repair qualify for the lateral rebate?

Des Plaines’ lateral program distinguishes qualifying defects inside the right-of-way or easement from defects elsewhere and routine private maintenance. The Plumbing Inspector verifies the location and repair route; financial assistance is limited. Have the inspector evaluate the actual finding before accepting a contractor’s estimate that deducts an assumed City reimbursement.

Can a Des Plaines flood rebate cover ordinary plumbing maintenance?

Des Plaines lists flood-prevention improvements such as overhead sewers and backwater valves in its rebate program but excludes ordinary maintenance, including routine sump replacements and sewer cleanouts. Give Community Development the actual project scope before budgeting assistance. A basement-related invoice alone does not establish that the work is an eligible mitigation improvement.

What should a Des Plaines landlord retain for a flood rebate application?

Des Plaines says single-family houses and townhomes can qualify for its flood rebate whether owner-occupied or rented. Applications require evidence including estimates, contractor invoices and payment proof, with processing after final approval. Confirm the property and project eligibility and preserve these records; landlord ownership does not itself disqualify or guarantee reimbursement.

What Des Plaines contractor check matters for work spanning New Year?

Des Plaines says contractor registrations expire December 31 and need renewal, and its trade table distinguishes licensing documents by contractor type. Before a project continues into the next year, confirm the selected contractor’s current City registration and trade requirements. A previous permit or an old registration receipt does not establish a renewed registration.

What extra Des Plaines transfer step applies to a nonowner-occupied house?

Des Plaines’ posted transfer provision says that, before transfer stamps or an exemption are issued, the applicant must either obtain a City determination that the property complies with the city code or sign a City-prepared compliance order under section 15-7-16.B, which covers inspection of nonowner-occupied property before sale. Ask the City which inspection and order apply to the actual rental. Clearing utility balances alone does not demonstrate this inspection condition is satisfied.
