Decatur housing stock and foundations
Craftsman bungalows, English cottages and Tudor revivals from 1915 to 1945, nearly all on brick pier-and-curtain-wall crawl spaces. Oakhurst in particular is close to uniform crawl space construction with almost no slab inventory.
Pier-and-curtain-wall with original clay-tile or brick piers. The curtain wall between piers is decorative infill, which surprises homeowners who assume it is holding the house up.
Soil: Cecil clay with a deep organic layer from a century of mature canopy, which holds surface moisture longer than exposed clay.
Permits in Decatur
Structural crawl space work in Decatur, meaning joists, girders, sill plates and piers, requires a residential building permit and a framing inspection. Encapsulation, vapor barrier, insulation and cleanout work does not, though a dedicated dehumidifier or sump pump circuit needs an electrical permit.
Decatur's tree protection ordinance is unusually strict for a city this size. Exterior crawl space drainage work that requires excavation inside the critical root zone of a protected tree needs arborist review before the permit is issued, which routinely adds time to exterior drainage projects.

The Decatur pattern
Decatur is a renovation city built on 1920s framing, and that combination drives most of the structural calls we take here. Oakhurst bungalows were framed with 2x8 joists for a house with one bathroom and no dishwasher. Add a second bath, a kitchen island and a laundry on the same floor system and the piers underneath start telling on themselves. The city's tree ordinance also shapes the repair: exterior drainage inside a protected root zone needs arborist review, so we often solve Decatur water problems from inside the crawl space instead.

Water and climate
Peavine Creek and South Fork Peachtree Creek watersheds. Decatur's older blocks have significant impervious coverage relative to their 1920s storm drainage. Decatur's protected tree canopy is among the densest inside I-285, so foundation vents sit in near-permanent shade and crawl spaces stay cool and damp into midsummer.
