Does Casselberry have zoning, and what does it mean for RVs, tiny homes and lot size?

Yes. Casselberry adopts its own zoning through its Unified Land Development Regulations, which set residential districts and district-based rules inside city limits¹. The residential districts include R-8, R-9, R-12.5, R-2F, RMH-8, PRD, RMF-13, RMF-20, PMX-L, PMX-H and RMHP⁸. Lot size, setbacks and house-size minimums depend on the district, and we could not confirm the single-family figures, so ask the City Planning and Zoning Division which district your parcel is in and what it allows⁷.

Manufactured housing may be permitted in all residential or mixed-use districts in Casselberry if the unit meets the city's standards, including the adopted building codes and appearance criteria⁵. Living in an RV, camping on private land, and tiny homes inside Casselberry are not something we could confirm; call Planning and Zoning before you plan around any of them⁷.

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

The City of Casselberry Building Division issues building permits for construction or alteration of buildings and other structures inside the city². The city adopts the Florida Building Code, plus the National Electrical Code and the Florida Fire Prevention Code as adopted by the State³. We could not confirm the city's exact exemptions or fee schedule for a new house, so ask the Building Division before you start work².

The Seminole County Building Division handles unincorporated Seminole County, not addresses inside Casselberry. Check Seminole County's page only for land outside city limits.

How do septic permits work for a Casselberry address?

Septic permits in Seminole County are issued by the Florida Department of Health in Seminole County, Environmental Public Health Program, not by the city⁴⁹. Florida law requires a permit to install, modify, repair or abandon a septic system¹⁰. The county's process starts with a state application form and a site evaluation, then fees and review⁴.

Whether a given Casselberry lot must use city sewer, we could not confirm. For mobile home parks the city requires sewer connection when a sanitary sewer is available within 100 feet of any part of the park¹¹. Seminole County's soils matter too: USDA rates 0% of its soils as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system¹².

Can an owner-builder pull their own permit in Casselberry?

Florida lets owners act as their own contractor on a one-family or two-family residence for their own occupancy, not offered for sale or lease, with direct onsite supervision¹³. A sale or lease within one year creates a presumption that the work was done for sale or lease¹³. The statute also requires the owner to satisfy the local permitting agency's requirements, and Casselberry's own owner-builder procedure is something we could not confirm, so ask the Building Division².

How do you build a home in Casselberry, step by step?

1. Ask Planning and Zoning for your parcel's zoning district and what it allows⁷.
2. Check whether the land is in a flood hazard area; the city's flood chapter applies to development wholly or partly inside one⁶.
3. Get a septic site evaluation and permit from the Florida Department of Health in Seminole County, unless city sewer applies⁹.
4. Apply for a building permit from the Casselberry Building Division².
5. Schedule inspections and request final approval through the city's online permit system².

If the lot needs a driveway or a well, we could not confirm the city's driveway rules; Florida requires a water management district permit before a water well is built¹⁴.

What stays with Seminole County, and what should you check before buying?

Septic permits, and the county's rules for unincorporated land, sit outside the city's building and zoning offices. For land outside city limits, see the Seminole County page. Seminole County's typical home value is about $404,888¹⁵, and its typical home insurance premium is about $2,664 a year¹⁶. Those are county figures, not Casselberry-only numbers.

Watch-outs

• We could not confirm whether Casselberry has rules for RV occupancy, tiny homes, accessory dwelling units, short-term rentals or driveways; ask City Planning and Zoning before you buy⁷.
• Land in a flood hazard area inside Casselberry carries extra development rules, including for manufactured home and RV placement⁶.
• Most of the building height rule we found applies to commercial and multifamily districts, where heights above 35 feet need a conditional use; we could not confirm the single-family height limit¹⁷.
• Seminole County's unincorporated-land rules, such as its accessory dwelling and RV rules, do not apply inside Casselberry¹⁸.
