Full Breakdown
The zoning code's residential development standards (§ 11.03.153) require every single-family home to have at least a fully enclosed two-car garage with working exterior doors that keep the street-facing appearance of a garage. Cedar Park carves out one exception: in the Semi-Urban Residential (SU) district, a homeowner may convert that garage to living space, but only if the required off-street parking is still provided elsewhere on the lot. The rule applies to dwellings on lots platted after the November 9, 2017 effective date of Chapter 11; the Development Reserve, Estate Residential, Suburban Residential, and Urban Residential districts have no comparable conversion allowance in this section.
Violations & Fines
Building without required approvals, or converting a garage outside the SU exception, is enforceable as a Class C misdemeanor under § 11.08.003, fined up to $2,000 per day the violation continues.
