Full Breakdown
Tyler recognizes garage apartments as an allowed household-living use (Sec. 10-50), so converting a garage into habitable space is possible, but Sec. 10-79(g) permits dwelling use of an accessory building only as a permitted garage apartment. A conversion needs a building permit and must meet the building code for habitable rooms, egress, and electrical, and the structure stays subject to accessory-building standards including the 16-foot height cap and 5-foot side and rear setbacks. Texas has no statewide garage-conversion mandate; Tyler regulates through its zoning and building codes. Off-street parking rules may require replacing any spaces the conversion removes.
Violations & Fines
Finishing a garage into living space without permits and inspections violates the building and development codes and can bring a stop-work order plus code-enforcement citations.
