Washington County, Kentucky Building Permit Guide

Washington County’s own FAQ is direct: buildings outside the Springfield city limits do not need a building permit. The state’s inspector sheet lists a local building inspector for the City of Springfield only and sends commercial construction elsewhere in the county to the Department of Housing, Buildings and Construction (502-573-0365). A county home still needs an electrical permit ($10 plus $70 for the rough and final inspection), state plumbing and HVAC permits, a health department septic approval and, on a county road, an entrance permit under Ordinance 2025-07. Planning questions go to the Washington County Planning Commission, 109 North Cross Main, Springfield (859-336-5415).

What requires a building permit in Washington County?

In the unincorporated county the answer depends on what kind of building it is. The county has no building inspection program of its own outside Springfield, and its FAQ says buildings there need no building permit. That does not make a project permit-free:

Inside Springfield, buildings are subject to the city’s planning rules and its local building inspector: see the city row in the table below. The city’s zoning form for a house, addition, accessory building or fence asks for a plan with property lines and distances to every structure, needs a sign-off from the Springfield Water & Sewer Commission and promises a response within 2 weeks.

What the county decides and what the state holds

Washington County runs subdivision regulations countywide, a comprehensive plan dated December 19, 2019, a road ordinance that controls every encroachment on county right-of-way, and an electrical inspection arrangement with its own fee schedule. The state, through the Department of Housing, Buildings and Construction, reviews and inspects apartment buildings (three or more units) and commercial and other non-residential buildings in places without a local program (one- and two-family homes and townhouses are outside its review), and issues plumbing and HVAC permits. Houses still have to meet the Kentucky Residential Code; where no local program exists the state says only the mechanical systems and the electrical work are inspected.

Washington County building department: who handles permitting

The county posts a two-page list, “Important Contacts for Building in Washington County” (updated August 4, 2026), and the state’s contact sheet (updated March 4, 2026) names the same arrangement: a local building inspector for the City of Springfield only, the state for commercial building permits, and the state electrical, HVAC, plumbing and manufactured-housing inspectors who cover the county.

Washington County permit types

Because the county issues no building permit outside Springfield, the paperwork for a county project is a set of separate approvals from different offices.

Residential permits

For a new house in the county, plan on a septic permit from the health department (or a water and sewer service from the Springfield Water & Sewer Commission where lines reach), an entrance approval for the driveway, an E911 address, an electrical permit and inspections, a state plumbing permit and a state HVAC permit. A manufactured home may go anywhere a site-built home may under the county’s FAQ; placing one for tenants needs special approval, and pre-1976 units are allowed only in certain areas, so talk to the planning office first. The state manufactured housing inspector covers installations in the county.

Commercial permits

Shops, churches, offices, warehouses and apartment buildings outside Springfield need a state building permit and plan review from the Department of Housing, Buildings and Construction before work starts; the county’s contact list gives the department’s number as 502-573-0365. A commercial entrance on a county road needs Judge/Executive approval of type, size and drainage pipe (15 inches by 28 feet at minimum), and any bond the Judge/Executive sets.

For tenant improvements and new commercial builds, Alliance handles commercial building permits through issuance. More on this: commercial building permits explained.

County road entrances

Ordinance 2025-07, re-adopted with amendments on October 13, 2025, requires a written permit from the County Road Supervisor before anyone places or changes anything in a county road right-of-way: driveways, culverts, fences, signs, tree planting or removal, structures and drainage work. The right-of-way usually runs well past the pavement edge, so check before setting a fence near the road. Farm and single-family entrances need no bond unless the work inside the right-of-way costs more than $500. Where a shoulder is grassed, the driveway must be surfaced far enough back to keep mud and stone off the road, and curbs must stop at least 10 feet from the pavement unless the Fiscal Court gives special permission. Where a shoulder is paved or stabilized for traffic, the driveway must be paved across it, though field entrances and low-use private drives may use gravel.

What comes before the building permit

• Land division. Splits and new lots go through the county’s subdivision regulations. Since the 2022 revision, an agricultural tract means at least 10 contiguous acres, and a private street may serve no more than three agricultural lots of at least 10 acres each.
• Septic. A health department evaluation and permit for any lot without public sewer.
• Driveway. County road: Road Department and Judge/Executive approval. State highway: the Kentucky Transportation Cabinet’s Washington County facility.
• Address. E911 addressing, 859-336-0746.
• Floodplain. The county participates in the federal flood insurance program; ask the planning office about mapped flood zones before building near a stream.

Washington County permit costs and fees

There is no county building permit fee outside Springfield because there is no county building permit. The fees a county project does meet are these:

Commercial percentages apply to the whole electrical contract, including fixtures and materials supplied by others. The printed bands meet at $5,000, so a contract of exactly that amount should be confirmed with the inspector. Worked example: a new house wired under one permit pays $10 plus $70 for the rough and final inspection, $80 in all; a $20,000 commercial electrical contract pays 3%, or $600.

Subdivision fees are set by the Planning Commission and are not posted online; ask the planning office for the current figures.

Trade permits and who may pull them

• Electrical. The county retains a residential and commercial electrical inspector, reached through the Judge/Executive’s office, under the fee schedule above.
• Plumbing. The state plumbing inspector holds office hours at the Washington County Health Department on Thursdays from 8 to 9:30 a.m. Permits go to licensed master plumbers, or to a homeowner for plumbing in the home they live in. Any other plumbing must be installed by a licensed journeyman working under a licensed master plumber.
• HVAC. State permit only, bought through SmartGov by a licensed or authorized installer; the state HVAC inspector covers the county.
• Licenses. The county collects an occupational license fee under Ordinance 2005-01 (Occupational Tax office, 859-336-5430), and Springfield requires contractors to hold a city license. Electrical, plumbing and HVAC licenses are state licenses.

How to build in Washington County

Review, corrections and what causes delay

The planning office keeps short hours (three mornings a week), so call before visiting. Driveway applications can stall when the Road Supervisor requires drainage pipe or, for commercial entrances, a bond. Commercial projects wait on the state’s plan review, and a lot without public sewer cannot move ahead without the health department’s approval. Encroaching on a county road without a permit carries a fine of up to $100 per day under the road ordinance.

Inspections in Washington County

Outside Springfield there is no local building inspection of houses. Electrical work is inspected by the county’s electrical inspector at the rough-in and final stages; for a single-family house one $70 fee covers both, and a reinspection costs another $70. The state plumbing and HVAC inspectors inspect the work under their permits; the plumbing inspector’s Thursday morning desk hours at the health department are the place to arrange it in person. Commercial buildings are inspected by the state building inspector assigned to the county, and the state sheet also lists an elevator and a boiler inspector.

The health department environmentalist handles septic evaluations and inspections. The county’s August 2026 contact list gives walk-in hours on Mondays and Wednesdays from 8:30 to 9:30 a.m. and 3:30 to 4:30 p.m.; the state’s March 2026 sheet printed Monday and Tuesday mornings, so call 859-336-0574 before going.

Kentucky building code in Washington County

FEMA’s Community Status Book lists Washington County as a participant in the National Flood Insurance Program, on a flood map effective May 23, 2023. Springfield has its own flood ordinance (No. 2009-006) and asks on its zoning form whether a lot is in a flood zone.

Kentucky has one mandatory statewide building code that local governments may not add to. Cities and counties enforce it and run zoning. The state reviews plans for larger and higher-risk buildings, and the local program reviews smaller ones. Kentucky rules

Permit search and official resources

The county has no building permit records outside Springfield. For road, subdivision or electrical records, ask the Judge/Executive’s office or the planning office; plumbing and commercial building permits sit with the state, which sells HVAC permits through its SmartGov portal.
