Deck Builder in Pasadena, MD

How do Critical Area rules affect a deck in Pasadena?

They set the size and location limits for any deck within 1,000 feet of tidal water or tidal wetlands. Many lots in Pasadena-area waterfront communities, such as Riviera Beach along Stoney and Rock creeks, sit that close. Three rules matter most.

First, lot coverage. Impermeable decks count toward a cap that runs roughly 15% to 31% of the lot, along with stairways, walkways and the driveway. On a small beach-community lot that already has a house and a driveway, there may be little room left.

Second, the 100-foot Buffer, measured landward from tidal water, tributary streams and tidal wetlands, and wider where there are steep slopes or erodible soils. Any disturbance there needs a buffer management plan and generally a variance. Clearing also has to be replaced with native plantings.

Third, exemptions disappear. Elsewhere in the county, a small detached deck under 200 square feet and 3 feet high may skip the permit. Inside the Critical Area it can’t.

Replacing a deck on a townhouse

Census estimates put townhouses at a third of Pasadena’s housing, and about 30% of all homes went up in the 2010s. Their decks are usually raised off the main living level, with stairs down to a small yard. A deck that’s 10 to 15 years old often has sound framing and tired boards, especially if it was built in pressure-treated lumber that was never sealed.

When the joists are good, new decking boards are the whole job and need no permit. If railings are loose or the stairs have to be rebuilt, it becomes permitted work, since Anne Arundel names railing and structural-member replacement among the deck jobs that need a permit. For a townhouse row we also keep materials and debris off the shared walks.

Waterfront decks and water access stairs

On a waterfront lot, we start with the existing footprint. Rebuilding on the same footprint keeps the project out of the hardest category, which is growing toward the water. If you want more deck, we look first at space on the land side of the house or beside it, outside the Buffer.

Stairs that run down a bank to the shoreline are their own item. The county permits residential water access stairs and trams as a Residential Accessory Structure, separate from the deck permit. Piers, bulkheads and rip rap also have their own permit types.

Choosing decking for a lot near the Bay

Composite boards don’t need staining and hold their color, which suits a deck that gets a lot of sun off the water. Pressure-treated lumber costs less at the start but needs cleaning and sealing every couple of years. We’ve built gray composite decks with white rails and black balusters, and re-decked balconies with two-tone composite boards and black metal railings. Fasteners and hardware matter near the water, so we choose corrosion-resistant ones.

Applying online

Permit applications in Anne Arundel County go through the Land Use Navigator, required for most new applications since December 1, 2025. We prepare the deck drawings, footing layout and site sketch, and for Critical Area lots we show existing and proposed coverage.
