Toronto屋主及预制建筑商向CBC反映，花园屋与后巷住宅的融资和审批仍有障碍。市府表示，目前755套此类附属住宅正在建设，另有627份许可证已经结案；这两个数字代表不同阶段，不能全部当作新近落成套数。

市府2018年及2022年分别放宽后巷住宅与花园屋分区规定，并提供预先批准的设计以降低设计成本、简化手续。未采用预批方案的项目仍须逐项核查材料、结构和施工方式；受访建商认为，工厂预制板件的审查流程尚未充分适应新技术。

市府称符合条件的项目可能获开发费豁免或延期，但并非每个项目自动符合。多伦多大学学者Matti Siemiatycki认为，附属住宅只是住房供应的一部分，不能自然等同可负担住房；受访屋主仍希望未来用作租赁收入或安置年长家人。
