Also worth knowing before you build in Oldham County

15 psf of snow — and Trimble and Henry, right next door, carry 20

Oldham fronts the Ohio River, and the instinct is to assume it inherits the Ohio River tier's heavier snow case. It does not, and the county line is where the number changes. The Kentucky Residential Code's Table R301.2(1) names 18 counties at a 20 psf ground snow load and puts every other Kentucky county at 15 psf. The 20 psf list runs along the river through Boone, Gallatin, Carroll and Trimble, and inland through Grant and Henry — and then stops. Oldham is not on it, and neither is Jefferson. So a build in the north-east corner of Oldham designs for 15 psf while a build a few miles up the river in Trimble County designs for 20, and the same step exists across the Henry County line to the east. Two more figures come from two more tables and they do not travel together. Table R403.1.4, Minimum Frost Protection Depth for Kentucky, names 33-inch, 30-inch and 27-inch exception counties and puts everything else — Oldham included — at 24 inches, the default that covers roughly 100 counties; the Northern Kentucky river counties at 30 inches are Boone, Campbell and Kenton, and that group does not extend downstream to Oldham either. Table R301.2.2.1 assigns Oldham Seismic Design Category B, so IRC R301.2.2 Exception 1 exempts a detached one- or two-family dwelling from the seismic provisions. Wind is 115 mph ultimate statewide from Table R301.2(1), with the code's own instruction that topographic effects shall be investigated — which is not boilerplate on an Ohio River bluff or on the 30-percent-plus slopes the county's comprehensive plan maps. Section R403.1.4 also carries a genuinely useful rule for this ground: if solid rock is exposed during preparation of the finished site grade, footings may bear on it and are not required to extend below the frost line — though on karst, bearing on rock has its own questions.

In Goshen you need two building permits, and a committee reviews how the building looks

Oldham County's zoning is a joint ordinance, and Section 010-140 names the Oldham County Planning Unit as four bodies: the Fiscal Court, the La Grange City Council, the Pewee Valley City Council and the Crestwood City Council. The Board of Adjustments that hears conditional use permits and dimensional variances is shared by Oldham County, La Grange and Pewee Valley. Cities outside that unit can still bind. Goshen, incorporated in 1990 out of the Harmony Lake subdivision, adopts the Oldham County Zoning Ordinance as amended from time to time by its own Section 152.01 — so the county's dimensional standards and the Section 250-030 accessory-structure table apply there — and then adds a layer of its own. Under Goshen Section 150.02, no building, outbuilding, driveway, grading, sloping, elevation, wall, fence, deck or treehouse may be erected, placed or altered on any lot until the construction plans, specifications and a location plan have been filed and approved in writing by the Architectural Control Committee as to quality of workmanship and material, harmony of external design with existing structures, and location with respect to topography and finished grade elevation — and until a city building permit has been obtained. Section 150.03 lets the committee require the county building permit, blueprints, a plot plan and a typed description of building materials as conditions of approval. Section 150.05 requires both the county permit and the city permit posted at the site throughout construction. Section 150.06 gives new home or garage construction 180 days from the committee's approval to finish, with extensions requested in writing at least 14 days ahead. The committee has 45 days to act, after which approval is not required. For a metal or post-frame building the phrase to plan around is harmony of external design with existing structures — that is a design-review test, and it is worth engaging with before drawings are finished rather than after. Note also that the county's 2020 population divides 46,905 in unincorporated Oldham against 20,702 across La Grange (10,067), Crestwood (6,183), Pewee Valley (1,588), Orchard Grass Hills (1,536), Goshen (892) and River Bluff (436), so roughly seven in ten Oldham residents live outside any city.

School capacity can stop a subdivision here, and can ration building permits per year

Oldham County runs a Capacity Standards system that very few Kentucky counties have, and Division 270 of the zoning ordinance sets it out: the legislative bodies establish the system to ensure adequate water supply, wastewater disposal, public schools and roads are available at the time developments are occupied, and a permit for a proposed development shall not be granted unless the appropriate legislative body has determined that the public facilities will be adequate. The school half has teeth. Section 270-050 says available school capacity shall be considered as part of the consideration to subdivide land, and that capacity inadequate to accommodate the students a project generates may be considered grounds for denial of a subdivision plat. Capacity and students-generated-per-dwelling are quantified from Oldham County Board of Education data reviewed at least annually, and the ordinance names the mitigation mechanism explicitly: the Board of Education has adopted a Campus Capacity Worksheet that averages the capacity of the elementary, middle and high school serving the development and applies a multiplier to generate the number of building permits allowed per calendar year for that development. Two things follow. First, this is the real supply constraint in a county whose schools are the reason many people move here — new lots are throttled, which is a large part of why the acreage market is what it is. Second, it does not reach a single house: Section 270-020 exempts single-family dwellings on a lot of record, along with developments approved before the regulations and alterations that create no additional impact. So buying an existing platted lot and building on it is outside the system entirely, while creating new lots is inside it. The same division sets fire-protection standards that do reach an individual build — buildings on private roads or shared access easements must be accessible by full-size fire apparatus, with bridges rated for it, and single-family detached development on lots of an acre or more with buildings including accessory buildings set back at least 30 feet from any property line needs 500 GPM of fire flow at a residual pressure of no less than 20 PSI, against 750 GPM for everything else.

$600 to the health department before the county will look at a building permit

Kentucky issues on-site sewage permits locally, under 902 KAR 10:085 for site evaluation and 902 KAR 10:110 for permit issuance, which places issuance with a certified inspector at the health department having jurisdiction. Oldham is served by the Oldham County Health Department — an independent county department rather than one of Kentucky's multi-county districts — at 1786 Commerce Parkway, La Grange KY 40031, 502-222-3516, with environmental services open Monday to Thursday 8am to 4:30pm and Friday mornings. Its published checklist for obtaining a building permit runs in a fixed order and prices each step: a site and soil evaluation application with a $300 fee, allowing 10 to 14 days for the fieldwork, which needs a backhoe on site and has to be complete before anything else moves; then a $300 on-site sewage construction permit, applied for by a certified installer unless the homeowner is installing, with a drawing of the proposed system required for issuance. An alteration permit is $300 and a repair permit $150, on fees adjusted 25 March 2022. The checklist then states the sequencing point that matters: once those requirements are met a certificate is issued for submission to planning and zoning for obtaining a building permit. So on an unsewered Oldham parcel — which is most of the county outside La Grange, Crestwood and the MSD footprint — $600 and the soil pits come before the building permit, and the proposed lateral field has to be protected from regrading and heavy equipment from that point on. Given that roughly 75 percent of the county's land area rates severe for absorption fields, this step is where an Oldham project most often changes shape.

The Ohio River, a brand-new flood map, and the state permit that stacks on the local one

Oldham fronts the Ohio for its whole northern boundary, from Prospect round past Goshen and Westport, and the county's comprehensive plan names the Ohio River as the county's only severe flood potential corridor while listing 26 internal creeks at moderate potential — Harrods Creek, Floyds Fork and its east and north forks, Currys Fork and its north and south forks, Cedar Creek, Eighteen Mile Creek, Brush Creek, Darby Creek, Hite Creek, Sinking Fork and the rest. FEMA's Kentucky Community Status Book lists unincorporated Oldham County as CID 210185 and the City of Crestwood as 210027, both participating in the National Flood Insurance Program on a current effective map dated 16 October 2025 — a remap barely a year old, which is the single best reason not to rely on what an owner remembers about a parcel's flood zone. Goshen (210397) and Orchard Grass Hills (210398) are listed participating on a 23 March 2021 map, with Goshen carried as NSFHA, all zones C and X. No Community Rating System class appears for any Oldham community in that listing, so no CRS premium discount should be assumed; only 33 Kentucky communities carry one. Locally, the Oldham County Engineer serves as Floodplain Administrator, and Goshen maintains its own floodplain management chapter. On top of whatever the local administrator requires, Kentucky requires a separate state Division of Water floodplain construction permit for work in the base floodplain, under KRS 151.250 and 401 KAR 4:060 §2, on form DOW 7116 — the state permit stacks on the local one rather than replacing it. And carry the county's own karst warning alongside the maps: flooding around karst features does not show up on FEMA flood maps, which in the county with 3,664 inventoried sinkholes is not a footnote.

No mine subsidence endorsement, no Zone 1 radon, no contractor licence — and no sinkhole cover either

Three Kentucky hazard programmes stop short of Oldham County, and one gap is worth acting on. Oldham is not among the 37 counties whose fiscal courts voted into the Kentucky Mine Subsidence Insurance Fund, so the automatic-with-written-waiver endorsement that KRS 304.44-030 attaches to policies in coal counties does not attach here — which is correct, because Oldham is in neither coal field. Oldham is also not on the 30-county EPA Zone 1 radon list, which in Kentucky is essentially the karst map, and which does include neighbouring Jefferson and Bullitt; that placement comes from third-party renderings of EPA's map rather than an EPA county table, and EPA's own caption says the Map of Radon Zones should not be used to determine whether an individual home needs testing. Test regardless — the Devonian New Albany Shale sits in the Oldham section, and black shale is one of the two rock types KGS names as high radon potential in Kentucky. The Kentucky Residential Code adopts appendices K, R and S and not Appendix F, so radon-resistant construction is nowhere required in Kentucky, and a passive sub-slab rough-in is cheap while the slab is open. The gap that matters most in this particular county is the insurance one: Kentucky built a statutory reinsurance fund for underground coal-mine collapse and nothing comparable for karst, and the Department of Insurance's own brochure states that a typical homeowners policy does not cover damage originating from earth movement, settling, shrinking, bulging or expansion of soil. In the county with 3,664 inventoried sinkholes, that exclusion is a written question for an agent before closing, not after. And on credentials: Kentucky issues no state contractor licence for residential general contracting, and nothing in Oldham County's published permit material adds a county contractor registration — the trades are licensed by the Commonwealth, with DHBC assigning named state electrical, plumbing and HVAC inspectors to Oldham, and KRS 198B.060(11) meaning no utility may energise a new building until a certified electrical inspector issues a final certificate.
