County guide
Setting a manufactured home in McLennan County
No county building permit in McLennan County, though the county appears to run a notice and third-party inspection model. Inside Waco city limits the rules are different and more involved.

City limits change the answer
McLennan is the county in this group where the unincorporated-versus-city-limits split matters most. Inside Waco, city permitting, zoning and inspection apply and are substantially more involved than the county process. Confirm which jurisdiction the parcel actually sits in before pricing anything.
The order to work in
The sequence is the same everywhere; what changes county to county is which permits attach and who issues them.
- 1
Confirm the land can be served
Which utility is certificated to serve this parcel, whether water is reachable, and whether the soil will take a septic system sized to the home.
Do this before closing, not after. - 2
Address and permits
A 911 address, then whatever county permits apply where you are — which is not the same list in any two counties.
A factory may not ship without an address. - 3
Pad, driveway and culvert
Grade set, fill placed and compacted, and access built well enough to carry a home down it.
The delivery has to physically reach the site. - 4
Septic and water
System designed to bedroom count and soil class, installed, inspected and approved. Tap set or well drilled.
Septic approval gates power in some counties. - 5
Meter loop and service
Service entrance built to the serving utility’s specification, inspected, then energized.
- 6
Set, anchor and finish
Home delivered and set, blocked and anchored, then skirting, steps and landings.
Common questions
Do I need a permit to put a manufactured home on my own land in McLennan County?
In the unincorporated county, the requirements are in the table above. Inside a city’s limits or its extraterritorial jurisdiction, the city’s rules apply as well and are usually more involved. Confirm which jurisdiction the parcel actually sits in first.
How long does the whole thing take?
Individual steps sometimes have published clocks. The total is governed by the septic design and inspection cycle and by the serving utility’s schedule, and neither publishes a guaranteed timeline. Plan in months rather than weeks.
What does the septic system cost here?
The permit is a few hundred dollars. The system is the real cost, and it is driven by bedroom count and soil class rather than by the county. Poorer soils need substantially more disposal area, which is what moves the number.
Who provides electricity out there?
Every county in this area has multiple certificated electric providers, with overlap at city fringes and in unincorporated areas. The serving entity has to be confirmed for the specific parcel — neighbors are not a reliable guide.
