Septic permits come from the Elmore County Health Department, and only where no public sewer is available34. Rural Elmore County's no-permit, no-zoning answer does not apply inside the city5.

Do you need a building permit in Millbrook, Alabama?
Yes. Millbrook requires a building permit before anyone starts excavating for or building a structure, including accessory structures such as sheds, and before moving, altering or repairing one. Small repairs that do not change the structure and cost no more than $500, plus painting and wallpapering, are the listed exceptions1.
The City of Millbrook says its permit requirement covers the city limits and its police jurisdiction, so land just outside the city line may still need a city permit9. Residential applications must be submitted by a state licensed general contractor10. Whether an owner can pull a permit for their own house inside the city is something we could not confirm; ask the Building Department before you plan on building it yourself9.
A residence cannot be occupied until it passes inspection and the city issues a certificate of occupancy6.
Who issues building permits in Millbrook, and how do you reach them?
The City of Millbrook Building Department issues building permits, and inspections for building, electrical, roofing, plumbing, mechanical, fuel gas and zoning work are scheduled through it11. Millbrook City Hall at 3160 Main Street takes calls for inspections and certificates of occupancy9.
Plans are reviewed by the Building Department, the Fire Department and the Zoning Administrator, and the Building Official gives final approval. Residential applicants submit one complete plan set10. Millbrook City Hall also holds the permit fee schedule; the city asks you to call for it9. Elmore County does not issue building permits for addresses inside the city5.
Does Millbrook have zoning, and what does it mean for homes, RVs and lot size?
Millbrook has its own zoning. The city identifies Zoning Ordinance Z15-01 and an official zoning map2, and the Planning and Zoning Administrator at City Hall handles questions and rezoning requests12.
Minimum lot size depends on the district. In the R-1 Low Density Residential District the minimum lot area is 15,000 square feet, and in the FAR Forestry-Agricultural-Recreation District it is 40,000 square feet1314. Where no community sewer is available and the Elmore County Board of Health percolation standards call for a larger lot, the Board of Health minimum prevails13.
A second dwelling in a rear accessory building needs written approval from the Board of Adjustment8. Millbrook's rules for living in an RV, tiny homes and temporary camping on a lot are not something we could confirm, so ask the Planning and Zoning Administrator before you buy12. Manufactured homes need a city installation permit, which costs $300.00 when the installation complies with zoning and health regulations7.
How do septic permits work inside Millbrook?
Septic starts with sewer. Millbrook requires a property used for human occupancy to connect to the public sewer within 10 days of written notice when a public sewer is within 300 feet of the property line15. Private sewage disposal is allowed only when public sewer is not available under that rule, or when the city engineer finds the sewage would be unacceptable to the city4.
When a septic system is allowed, Elmore County's onsite sewage permits come from the Elmore County Health Department3. Alabama requires a permit before a new onsite system is installed or an old one repaired, and only registered engineers may design systems where soil percolation exceeds 60 minutes or where a shallow limiting zone exists16. In Elmore County, about 37% of soils rate as not limited for a conventional drain field, so a site evaluation is a realistic expectation17.
Building a home in Millbrook: the steps, in order
- Call the Planning and Zoning Administrator at City Hall to confirm the zoning district and the minimum lot area for the parcel1312.
- Ask the city whether public sewer is within 300 feet of the property line; if it is, plan to connect15.
- If no sewer is available, apply to the Elmore County Health Department for a Permit to Install before any construction starts18.
- Have a state licensed general contractor submit the building permit application10.
- Check flood risk first: in special flood hazard areas, the lowest floor must sit at least 1 foot above base flood elevation where that data exists19.
- Schedule inspections through the Building Department and get the certificate of occupancy before anyone moves in6.
What stays with Elmore County, and what to check before you buy in Millbrook
Septic permits for Millbrook addresses stay with the Elmore County Health Department rather than the city3. We could not confirm a permit requirement for private wells inside the city, so ask the health department before you drill.
For land outside the city limits, Elmore County's answers differ: the county says there are no zoning restrictions or building permit requirements for rural property that is not inside a municipality's planning jurisdiction5. See the Elmore County page for that land. Because Millbrook's permit rules reach into its police jurisdiction, confirm with City Hall which side of the line a parcel falls on9.
County-level costs: Elmore County's effective property tax rate is 0.3%20, and the typical home value is about $274,66321.
Watch-outs
- Millbrook's permit requirement extends to its police jurisdiction, so a parcel outside the city line may still need a city permit; confirm with City Hall9.
- We could not confirm Millbrook's rules for RV living, tiny homes, temporary camping or owner-built homes; ask the Planning and Zoning Administrator and the Building Department before you buy12.
- Elmore County's no-zoning, no-building-permit answer applies to rural land outside a municipality's planning jurisdiction, not to land inside Millbrook5.
