Searching “deck builders near me” or “deck contractors near me” in Baltimore turns up everyone from rowhouse renovation crews to suburban deck companies, and spring calendars book up fast. Compare the three ways to get a new deck, from hiring a deck installer to assembling a DIY deck kit, and see which fits your yard, budget and timeline.

I am far from a handyman but the wife wanted a deck in the backyard and I couldn’t see myself dishing out $20,000 for someone to come build it for us. I ended up seeing an ad for this company and was blown away by the price and ease of install. 2 of our neighbours ended up ordering as well!

Baltimore sits where the Patapsco River meets the Chesapeake Bay, so decks here face hot, humid summers, heavy thunderstorms, the occasional nor’easter and winters that swing between snow, ice and rain. Plan for all of them before you choose decking materials and a deck foundation.
Built for four-season Baltimore backyardsBWI averages about 19 inches of snow a season, often in a few heavy storms mixed with sleet and ice. Applicable A-DIY configurations are engineered to hold up to 15,000 lbs when properly assembled and supported. Clear snow with a plastic shovel instead of piling it against the house.
Baltimore City sets its frost line at 30 inches, and winter temperatures cross freezing again and again. Attached decks generally need footings below that depth. Freestanding ground-level decks, like A-DIY kits that assemble 15–17 inches off the ground on Tuff Block footings, should be checked for level each spring.
BWI averages about 45 inches of precipitation a year, much of it in summer downpours. Site the deck where water drains away from the house, keep board gaps clear and leave airflow underneath so the framing dries between storms.
July highs average close to 89°F with thick humidity. Seal pressure-treated wood every one to two years to limit checking and graying, or choose composite decking for a surface that never needs staining.

Baltimore’s building season runs longer than in much of the Northeast. Most homeowners build between April and October, steering around the hottest, stormiest stretch of midsummer when they can. Plan and order over the winter so your permit and kit are ready when spring weather settles.
Measure, choose size and material, check DHCD and CHAP rules and lock in today’s price.
Submit your permit, schedule delivery and level the site once the ground is firm.
Mild, drier stretches make ideal weekends for a DIY build or a local installer.
Work early on hot days, then seal wood in early fall before winter storms.

Kits assemble 15–17 inches off the ground. Add steps, railings or a longer post kit with bracing for a raised deck, or ask about a size that isn’t listed. Our deck specialists will help you plan the right layout for your yard.
An A-DIY deck may be installed over sloped or uneven ground by adjusting the supporting post heights to establish a level deck surface.
Supported configurations may be elevated to approximately 40 inches using the appropriate posts, foundations and bracing.
Depending on the height and configuration, the project may also require:
Depending on the property, configuration and local approval, suitable systems may include:
Baltimore City did not adopt the standard IRC permit exemption for small decks, so most new decks inside city limits need a building permit from the Department of Housing & Community Development (DHCD), even low freestanding ones. Baltimore County is a separate jurisdiction with its own rules. Use the quick check as a starting point, then confirm with DHCD.
Rule of thumb: plan on a DHCD building permit for any new deck in Baltimore City, attached or freestanding.
General guidance for Baltimore-area decks
*Not in Baltimore City: the City did not adopt the IRC exemption for freestanding decks 200 sq ft or smaller and no more than 30 in. above grade, so the “Often exempt” note does not apply here. Confirm with DHCD, and expect zoning, CHAP or Critical Area review where they apply.
Baltimore City DHCDDeck permits are issued by the Department of Housing & Community Development, with zoning review of setbacks and lot coverage. Rooftop decks follow separate City guidelines. Addresses in surrounding Baltimore County, such as Towson or Catonsville, apply to the County instead.
CHAP & Critical AreaExterior work in a City historic district or on a City landmark needs a CHAP Notice to Proceed before the permit is issued. Lots within 1,000 feet of tidal water along the harbor and Patapsco shoreline fall in the Chesapeake Bay Critical Area, where lot-coverage and buffer rules apply.
MarylandEvery Maryland jurisdiction enforces the Maryland Building Performance Standards, based on the 2021 IBC and IRC. Baltimore City adopts them with local changes in its 2024 Building, Fire and Related Codes, including a 30-inch frost line.
Confirm setbacks and lot coverage, and whether your property is in a historic district or within 1,000 feet of tidal water.
Show the deck’s location, size, height, footings and setbacks. A-DIY engineering diagrams can help.
Apply to DHCD Permits and Inspections, with any CHAP Notice to Proceed your property needs.
Book the footing and final inspections your permit requires, then enjoy the deck.
Our deck specialists can help you plan size, height and placement before you apply.
Yes. Engineering diagrams for applicable A-DIY configurations show dimensions, structural layout, beam and joist sizes and post locations to support your application. Your department may still ask for a survey, site plan or stamped documents.
Requirements change and can differ between neighboring municipalities. Always confirm current rules with your local building department before you build.
