Local know-how
Why homeowners build in Glendora
Glendora’s foothill setting makes for beautiful properties and a few real engineering considerations. The lots climbing toward the San Gabriels north of Sierra Madre Avenue can mean slope, views, and grading questions worth getting right — and that is precisely where our up-front property analysis pays off. One Glendora homeowner called his build the most pleasant experience he’d ever had constructing a structure, and getting the foundation strategy right on a hillside lot is a big part of why.
Closer to the Glendora Village and the flatter south side, projects are more straightforward and a great fit for a rental or a family suite. Either way, we design to the lot rather than forcing a template onto it.
Glendora is an easy reach from our Upland office, so we stay close to your project throughout.

Good to know
Glendora ADU questions, answered
Often, yes. Hillside lots take extra planning for grading and foundations, which is exactly what our Formal Property Analysis is designed to resolve before construction starts.
Backyard Estates uses all-in pricing covering design, permits, and construction. Foothill lots can add site work, so your exact figure is confirmed on-site during your property analysis, fully credited toward the build.
The City of Glendora Planning Division reviews ADU applications, and Backyard Estates manages the process for you.
