Backyard ADUs like this are being built across Oviedo — here's how to do it right.
What Oviedo's zoning may allow for an ADU
Oviedo allows only a 'guest cottage / mother-in-law suite,' and only by special exception in four low-density districts (A, R-CE, R-1AAA, R-1AA). It is restricted to intermittent occupancy by a non-paying guest or a non-paying family member, so it may not be rented. There is no rentable ADU pathway.
Zoning allowance
A guest cottage is a special-exception use (never by right) in the A, R-CE, R-1AAA, and R-1AA districts (Table 4.1); it is not permitted in any other district. The main residence must have a Certificate of Occupancy before a guest cottage may be approved.
Size limits
No explicit maximum floor area is stated for a guest cottage. As a detached accessory structure over 120 sq ft it must meet the district's principal-structure setbacks (LDC §4.15/§4.12).
Lot + setbacks
Setbacks, lot coverage, and minimum lot size for an accessory dwelling vary by zoning district. Confirm the exact figures with the jurisdiction's planning department.
Height + coverage
Height and lot-coverage limits vary by zoning district. Confirm current limits with local planning.
Parking
Parking requirements for an accessory dwelling vary by district; typically one additional space. Confirm with local planning.
Rental / occupancy
Not rentable: a guest cottage is 'intended for intermittent or temporary occupancy by a nonpaying guest or permanent occupancy by a non-paying family member' (LDC definition). No paying tenant is authorized.
Permit process
An accessory dwelling is permitted through the jurisdiction's standard zoning-review and building-permit process. Contact the local planning or building department for current requirements.
