Basement Remodeling in Baltimore, MD: Plan and Hire

Masters' Guild · Updated

For Basement Remodeling in Baltimore, MD, define your intended room use, arrange a site assessment, and compare written bids from contractors whose current MHIC licenses you verify. Before signing, ask who will confirm permit requirements and whether proposed exterior changes need historic-preservation review. Maryland's home-improvement guidance calls for license checks, written material selections and confirmation that the contractor will obtain necessary permits. [3] [4]

Define the room before requesting bids

Tell each contractor whether you want a recreation room, home office, bathroom, sleeping room or separate living arrangement. Describe how you intend to use the space rather than asking for a general basement finish. Ask the contractor to identify which parts of your plan need confirmation with the permitting office before you select finishes.

Walk through the basement together. Point out water stains, odors, cracks and any areas that have become wet. Ask for a written assessment of the proposed preparation work before anyone covers the walls or floor. Have the contractor measure headroom, stairs, doorways and the route for moving materials, and discuss access to equipment and shutoff valves.

Separate your must-have work from optional features. Request distinct bid items for room preparation, partitions, lighting, flooring, bathroom work and exterior openings. Give each bidder the same room-use description and material preferences so you can compare the proposed work without guessing what each price includes.

Confirm the city application and preservation path

Baltimore City's E-Permits portal offers property information lookup, application searches and inspection scheduling. You can view information without an account; the city requires an account to use all portal services. Start by checking the property information and asking the permitting office which application fits your proposed basement work. [1]

Effective July 1, 2026, the city collects construction application fees at submission. The portal lists $25 for a one- and two-family combo application and $50 for a commercial and multifamily combo application. The notice says the fee amount did not change and that the city no longer includes this charge in the fees due at the end of permitting. Ask your contractor to identify the appropriate property category and list other permit charges separately. [1]

If you propose exterior changes, ask whether the property and alteration fall under CHAP review before ordering windows or finalizing an entrance. Under section 8-4, the Building Official cannot issue a permit for a regulated alteration without the applicable preservation authorization or determination. CHAP may request additional plans and must have a complete application and the other information it needs before making its determination. [2]

Choose a contractor through checks and comparable bids

Maryland's Home Improvement Commission advises homeowners to see the contractor's MHIC license and check that it remains current. The commission also recommends getting at least two bids, requesting current general liability and workers' compensation insurance certificates, and speaking with local references. You can contact MHIC at 410-230-6231 or 1-888-218-5925. [3]

Ask references about the work that matters to your project: how the contractor handled discoveries after opening walls, communicated changes, and completed unfinished items. Request a basement example with a similar intended use. During the estimate visit, ask who will supervise the job, coordinate the trades and communicate with you.

Compare exclusions as closely as included work. Ask each bidder to identify who handles demolition debris, material deliveries, permit applications and inspection appointments. Request written answers about any work the contractor cannot price until further assessment. Avoid treating an unspecified allowance as a confirmed price for your chosen fixture or finish.

Put scope, payments and completion in writing

Maryland requires a legible written home-improvement contract signed by both parties. It must include the contractor's name, address and MHIC license number, a description of the work and materials, and approximate start and substantial-completion dates. The homeowner must receive a signed copy before work starts. [4]

The contractor cannot accept payment before you sign the contract or accept more than one-third of the contract price as a deposit. Beyond that initial deposit, Maryland's Home Improvement Law does not control the payment schedule. Negotiate later payments around clearly described stages and make sure you understand what completion means for each stage. [4]

Ask for a written change process that states the added or removed work, price and schedule effect before you approve it. Agree on a final walkthrough and a list of remaining items. Keep the signed contract, changes, payment records and project correspondence together. Before the crew leaves, ask for equipment instructions and any permit or inspection records associated with the work.

Local details that affect your job

Budget for the submission fee at application time

Baltimore City now collects the $25 one- and two-family construction combo application fee when you submit, following the July 1, 2026 payment-timing change. Ask your contractor whether the quote includes this initial charge and who will submit the application. The $50 commercial and multifamily category should prompt a category check if your property contains multiple dwellings. [1]

Resolve regulated exterior alterations before ordering

For a regulated alteration in a Historical Preservation District, section 8-4 requires the Director's Authorization to Proceed before permit issuance. In a Historical Conservation District, the code allows that authorization or a CHAP determination that the proposed exterior alteration does not require it. Ask the city which route applies to your proposed basement opening, and make material ordering contingent on that answer. [2]

Frequently Asked Questions

How much should I budget for the remodel?

Obtain site-specific written bids for your intended room use. Ask bidders to separate preparation work, finishes, trade work and permit charges. The city's published $25 residential combo application fee covers the application charge for that category; it does not establish a remodeling price or total permit cost. [1]

Does every basement project need CHAP approval?

Section 8-4 addresses regulated alterations and distinguishes Historical Preservation Districts from Historical Conservation Districts. Ask the city whether your property and proposed alteration fall within those rules. Do that before committing to an exterior opening design. [2]

How do I check the remodeling contractor?

Ask to see the MHIC license and confirm with the commission that it remains current. Maryland also recommends insurance certificates, local references and at least two bids. Speak with references before hiring and ask about completion, communication and the agreed budget. [3]

Can the contractor collect half the price as a deposit?

Maryland's home-improvement contract guidance says a contractor cannot accept more than one-third of the contract price as a deposit and cannot accept payment before the contract is signed. You and the contractor can negotiate the later payment schedule. [4]
