Your backyard holds more value than you think. AltoADU helps Bay Area homeowners create beautifully built, fully permitted ADUs — for family, for income, for the life you want to build. 你的后院，比你想象的更有价值。AltoADU 专为湾区华人家庭打造——精工建造、全程报建、一站交付，为父母、为孩子、为你更好的生活。
Bay Area families know the challenge: a home that can't grow with you. Whether parents are moving closer, adult children need their own space, or you simply want a quiet retreat — an AltoADU is the most thoughtful solution your backyard can offer. 湾区华人家庭懂得这份难处：房子总是不够住。父母来了要有地方住，孩子大了需要独立空间，或者只是想在后院有个安静的角落——AltoADU，就是为这些真实需求而来。
We evaluate your lot, zoning, setbacks, and utility access — giving you a clear picture of what's possible before you commit. 评估地块条件、分区法规、退缩距离与水电接驳——在你做决定之前，先把真实情况摆清楚。
Our team handles every permit submission, revision, and follow-up directly with Bay Area building departments. Target: 10 business days. 从图纸提交到审批跟进，与湾区各城市建设部门直接对接，全程处理，目标 10 个工作日内拿证。
Factory-complete units installed by our certified local partner network. Site prep, utilities, crane, and final inspection — fixed price, fully managed. 工厂精制完成后，由认证本地施工团队完成安装——地基、水电、吊装、验收，全部包含，固定价格。
AltoADU was founded by a team with deep roots in both the Bay Area community and the modular construction industry. We understand the housing market here, California ADU law, and we've built strong relationships with the best local contractors and engineers. AltoADU 由深耕湾区社区与预制建筑行业的团队创立。我们了解这里的房市，熟悉加州 ADU 法规，并与湾区顶尖的本地承包商、建筑师和工程师建立了深度合作关系。
We specialize in serving Bay Area families — including the many multigenerational households where parents and adult children want to stay connected while maintaining their own space. 我们专注服务湾区家庭——尤其是那些希望父母与子女既彼此陪伴、又保有独立空间的多代同堂家庭。
"Our goal is simple: help Bay Area families make the most of the space they already own — beautifully, affordably, and without the usual stress." "我们的目标很简单：帮助湾区家庭，把自己已经拥有的空间用好——建得漂亮，花费合理，过程不焦虑。"
We are actively building our Bay Area installer and dealer network. If you are a California-approved modular manufacturer, licensed contractor, or ADU product supplier looking for a dedicated Silicon Valley partner — we want to hear from you. 我们正在积极搭建湾区安装商与经销商网络。如您是加州认证预制住宅制造商、持照承包商或 ADU 产品供应商，欢迎联系。
