Does Muscle Shoals, Alabama have zoning?

Yes. Land inside Muscle Shoals city limits, including residential districts, is subject to the city zoning chapter and its district regulations1. The city's code publishes its districts, including the FP-1 floodplain district, which exists for land used for or suitable for agriculture, forestry, recreation or other open space6. We could not confirm the dimensional schedules for the residential districts (minimum home size, lot coverage, setbacks), accessory dwellings or tiny homes, so ask the Building, License & Zoning office which district a lot sits in before you plan a build2.

The county's no-zoning answer does not apply here. Colbert County has adopted no county zoning ordinance, but that covers unincorporated land only; see the Colbert County page for rules outside city limits7.

Can you live in an RV on your lot in Muscle Shoals?

No. Muscle Shoals bars living, sleeping or housekeeping in major recreational equipment parked or stored on a residential lot, or in any location not approved for such use4. Equipment may be parked on residential premises for loading or unloading for no more than 24 hours4. A camper or RV is therefore not a way to live on a city lot while you build. We could not confirm a general temporary-camping rule, so call the city zoning office with any other plan2.

Do you need a building permit in Muscle Shoals, and who issues it?

Yes. The City of Muscle Shoals Building, License & Zoning office, at 2010 East Avalon Avenue, sells residential building permits2. Homeowners acting as their own contractor and licensed homebuilders can purchase them2.

The city states a one-day turnaround after you submit paperwork for a building permit2. A plot plan drawn by a registered land surveyor, showing the structure and setback lines and whether the property is in a designated flood zone, is part of the residential application2.

How do septic permits work inside Muscle Shoals?

Septic permits stay with the county, not the city. When a Muscle Shoals property has no sanitary sewer, the city requires a permit from the Colbert County Health Department3. The department's Environmental Office takes septic tank requests at 256-383-12318. Colbert County's soils rate poorly for conventional drain fields in many places, since only about 23% are rated not limited, so expect a site evaluation and possibly an engineered system if sewer is not available9. We could not confirm septic inspection rules, any mandatory sewer-connection rule, or a private-well permit rule inside the city.

Building a home in Muscle Shoals: the steps, in order

  1. Call the Building, License & Zoning office at 256-386-9205 and confirm the lot's zoning district2.
  2. Order a plot plan from a registered land surveyor showing the structure, setbacks and flood zone status2.
  3. If no sanitary sewer serves the lot, get a septic permit from the Colbert County Health Department3.
  4. Submit paperwork and buy the building permit as a licensed homebuilder or as a homeowner acting as your own contractor2.
  5. Owner-builders: Alabama's exemption requires you to provide all material supervision, and the home may not be offered for sale10.

What to check before you buy land in Muscle Shoals

Start with the zoning district and flood zone, since the city asks for flood-zone status on the plot plan2. For a planned residential development of at least 2 acres with two or more residential buildings, final plan review and planning commission approval apply5. Figures below are for Colbert County as a whole: the effective property tax rate is 0.4% and the median property tax bill is $604 a year1112.

Watch-outs

  • Colbert County's rules for unincorporated land do not apply inside Muscle Shoals, and the city's rules do not apply outside its limits7.
  • We could not confirm residential district setbacks, minimum home size, accessory dwelling or tiny-home rules; ask the city Building, License & Zoning office before buying2.
  • Septic permits come from the Colbert County Health Department, not the city, wherever sanitary sewer is unavailable3.
