How old are homes in Fayette County, and what does that mean for decks?
The median home in Fayette County was built in 1993; 1% predate 1960 and 33% were built since 2000.
Fayette County has about 46,453 homes, with a median construction year of 1993 (the Georgia median is 1992). Within our covered ZIP codes — about 33,821 homes — the median is 1995, close to the county as a whole.
The median home in the covered parts of Fayette County was built around 1995. A deck built with a house of that age is now about 31 years old — the stage where first-generation pressure-treated decks commonly need major repair or replacement.
Decks built before 2004 were very likely made with CCA-treated lumber, which was phased out of most residential uses at the end of 2003. That doesn't make an existing deck unsafe, but old boards shouldn't be burned, and demolition debris should be disposed of according to local rules.

Which Fayette County communities have the oldest and newest homes?
Among covered Fayette County communities, Peachtree City has the oldest housing (median 1993) and Tyrone the newest (median 1997).
Oldest housing: Peachtree City (1993), Fayetteville (1996) and Tyrone (1997). In these communities, expect retrofit decks on older houses and aging decks that need structural inspection, ledger and flashing upgrades, or replacement. Newest housing: Tyrone (1997), Fayetteville (1996) and Peachtree City (1993). Here, projects lean toward enlarging builder-installed decks, adding stairs and railings, and upgrading to low-maintenance boards.
How does Fayette County's climate affect deck building?
Covered parts of Fayette County average about 65 days a year at or below freezing (NOAA 1991–2020 normals).
The nearest NOAA climate station with 1991–2020 normals is Atlanta, about 2 miles away. It records an average of 65 days a year with a low at or below 32°F — a moderate number of freezing nights. On roughly 64 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 Fayette County 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 0.8 inches in an average year at Jonesboro — so occasional ice is a bigger concern than snow load. Textured boards and good drainage on stairs help on icy mornings.
Precipitation averages about 49.3 inches a year, falling on about 74 days with 0.1 inch or more — wet enough that drainage and flashing still matter, but dry spells also let wood surfaces dry out and check in the sun.
Summers are hot: average summer highs are near 90°F, with about 51 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.
What deck projects are most common in Fayette County?
Based on the age of Fayette County's housing, the largest group of projects is likely to be replacing or rebuilding aging decks.
- Replacement and major repair: about 29,115 homes (63%) 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.
- Upgrades and expansions: about 5,618 homes (12%) 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.
- Retrofit decks on older homes: about 2,082 homes (4%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.

Who issues deck permits in Fayette County?
It depends on where you live: incorporated cities and towns in Fayette County usually run their own permit offices, while unincorporated areas are typically served by Fayette County.
Georgia adopts statewide minimum construction codes that local governments enforce, often with local amendments. Your city or county building department issues deck permits. Before work starts, confirm with the building department for your exact address whether a permit is required, what drawings and inspections it involves, and whether an HOA must approve the design.
