How old are homes in Clarkston, and what does that mean for a deck?

13% of homes in Clarkston's covered ZIP code were built in 2000 or later and 10% before 1960; the largest group dates to the 1970s.

Homes in Clarkston have a median construction year of 1978, so a deck original to a typical house would now be about 48 years old — beyond the point where wood framing, fasteners and flashing can be assumed sound.

Many decks from the 1970s and 1980s were built before today's detailed deck provisions appeared in model codes. Common issues on decks of this age include corroded hangers, posts set directly in soil and ledger boards fastened with nails. Replacement is often the better value than repeated repairs.

That makes Clarkston's housing 6 years older than DeKalb County as a whole, where the median home was built in 1984. Statewide, the median Georgia home was built in 1992. Among the 43 covered Georgia communities with Census data, Clarkston ranks #4 for oldest housing. In this ZIP code, 10% of homes were built before 1960, 45% between 1960 and 1979, 32% between 1980 and 1999, and 13% since 2000 — the single largest group dates to the 1970s.

What does Clarkston's climate mean for deck construction?

Clarkston averages about 49 days a year at or below freezing, 0.5 inches of snow and 51.4 inches of precipitation, based on NOAA 1991–2020 normals.

The nearest NOAA climate station with 1991–2020 normals is Atlanta Peachtree AP, about 6 miles away. It records an average of 49 days a year with a low at or below 32°F — relatively few freezing nights. On roughly 47 of those days the temperature climbs back above freezing, so water in wood, soil and gaps between boards repeatedly freezes and thaws.

Frost is less severe in Clarkston than in northern states, but footings still have to meet the local frost-depth requirement, and freeze-thaw cycles are enough to work loose nails and open checks in unsealed wood.

Snowfall is light — about 0.5 inches in an average year at Atlanta 9nw — so occasional ice is a bigger concern than snow load. Textured boards and good drainage on stairs help on icy mornings.

Clarkston sees about 51.4 inches of precipitation a year, with measurable rain or snow (0.1 inch or more) on about 77 days. Good drainage between boards, clean gaps and a ledger that is properly flashed keep that water from rotting the frame.

Summers are hot: average summer highs are near 88°F, with about 53 days a year reaching 90°F or more. Surface temperature is a real consideration — lighter board colors, shade from the house or a pergola, and heat-mitigating composite lines are worth comparing.

Which decking material makes the most sense in Clarkston?

For most Clarkston homes, light-colored composite or pressure-treated wood is the strongest starting point because about 53 days of 90°F+ heat make board color and surface temperature important.

Budget, upkeep tolerance and sun exposure on your particular lot still decide the final choice between these options.

What kinds of homes are in Clarkston, and how does that shape deck design?

Clarkston has about 8,618 housing units across its covered ZIP code. 24% are single-family detached homes, 6% are attached homes such as townhouses and rowhouses, and about 70% are in buildings with two or more units. Roughly 25% of occupied homes are owner-occupied.

Because so much of the housing in Clarkston is multi-unit, a meaningful number of decks and balconies are governed by condominium or building associations. For single-family homes and townhouses here, check whether any association rules apply before you design.

Because fewer than half of homes here are owner-occupied, rental property owners make up a share of deck decisions here; durable, low-maintenance materials often make sense for them.

What deck projects are most common in Clarkston?

Based on the age of Clarkston's housing, the largest group of projects is likely to be replacing or rebuilding aging decks.

  • Replacement and major repair: about 5,238 homes (61%) were built between 1970 and 1999, the age group whose original or early add-on decks are most likely to have worn-out framing, connectors and boards.
  • Retrofit decks on older homes: about 2,273 homes (26%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.
  • Upgrades and expansions: about 245 homes (3%) were built since 2010. Their decks are usually sound but small or builder-grade, so enlarging the deck, adding stairs and switching to composite or upgraded railings are common.

When is the best time to plan a deck project in Clarkston?

Clarkston's milder winters — about 49 freezing nights a year — allow construction through most of the year. Peak summer heat (around 53 days at 90°F+) is the hardest time to apply stain or work in full sun, so many projects are scheduled for spring and fall.

Do you need a permit to build a deck in Clarkston?

Often, yes — especially for attached or elevated decks — but the rules are set locally. Check with the building department that serves your address: the municipality, or DeKalb County for unincorporated areas.

For Clarkston, GA, ask the permit office whether your deck needs a permit based on its size, height and attachment to the house, which drawings and inspections are required. Statewide code background for Georgia is on our state page; local rules change, so the building department remains the authority.
