Prefab & Modular ADU Installation in Palo Alto
Factory-built modular ADU delivered and set on your prepared foundation for a faster build timeline.
Factory-Built Speed, Site-Built Quality Control
A prefab or modular ADU is built largely in a factory under controlled conditions, then trucked to your property and set onto a foundation we prepare on site. Because the module is built in parallel with site work and permitting, the total timeline is often shorter than a fully site-built ADU.
We manage the full process: site prep and foundation, coordinating delivery and crane-set of the module, and all the utility hookups, finish work, and inspections needed to turn a delivered box into a livable, permitted home.
- Site work and permitting run in parallel with off-site factory construction
- Foundation, utility trenching, and crane-set day managed by our crew
- Final hookups, trim, and finish work completed on site after set
- Often a faster overall timeline than ground-up construction
Frequently Asked Questions
Is a prefab ADU cheaper than a site-built ADU?
It can be, particularly on labor and timeline, but site prep, foundation, delivery, crane-set, and utility hookups still add real cost — we give you the true all-in number, not just the factory unit price.
How is the prefab unit delivered and installed?
The module is trucked to your site and set by crane onto a foundation we prepare in advance. We coordinate street access, permits for the crane, and the full utility connection afterward.
Does a prefab ADU still need City of Palo Alto permits?
Yes — prefab and modular ADUs go through the same City of Palo Alto plan check and permitting process as site-built units. We manage that full process.
Can I customize a prefab ADU?
Most manufacturers offer finish-level and layout options within their base models. We help you choose a manufacturer and configuration that fits your lot and budget.
