What Titusville's zoning may allow for an ADU
Titusville allows one ADU per lot accessory to a single-family home, up to 950 sq ft (35% of the primary home, minimum 300 sq ft). Standard residential-district ADUs do not require owner-occupancy and read as rentable second units. (This corrects an unsourced 750 sq ft figure.)
Zoning allowance
One ADU is permitted per lot accessory to a single-family dwelling in Titusville's RE, RR, R-1A/B/C, RHP, OR and mixed-use districts (LDR §28-351); it is not permitted accessory to a duplex, multifamily or mobile home.
Size limits
A Titusville ADU may not exceed 35% of the primary dwelling's floor area, with a minimum of 300 sq ft and a maximum of 950 sq ft (LDR §28-351). This corrects an unsourced 750 sq ft figure.
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 (see the verified size and district notes above).
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
Standard residential-district ADUs have no owner-occupancy requirement and are not restricted to guest use (they read as rentable). Owner-occupancy and a no-rental rule apply only to the separate IRCN-C commercial-lot variant (LDR §28-351). Short-term-rental treatment is not addressed in this sectio
Permit process
An accessory dwelling is permitted through the jurisdiction's standard building-permit / zoning-review process. Contact the local planning or building department for current requirements.
