About Modera Services
Building your Detached ADU shouldn’t feel overwhelming. We provide homeowners with expert guidance through every regulation, every permit, and every construction phase – turning your property’s potential into a profitable reality.
How We Started
Founder Vasiliy Frantsevich saw something frustrating time and again: countless families missing out on the incredible benefits of a detached ADU. These backyard units can generate steady rental income, boost property value, provide space for multigenerational living, or offer retirement flexibility. Yet most homeowners never pursued them. Overwhelmed by confusing zoning rules, lengthy permitting processes, site challenges, and the fear of costly mistakes, they simply didn’t know where to begin. That’s why Vasiliy founded Modera Services: to guide homeowners through every step, from feasibility assessment to permitting and construction, so they can confidently unlock this valuable opportunity and turn unused backyard space into lasting financial and lifestyle gains.
What Drives Us
Three core principles guide everything we do at Modera Services:
Deep DADU Knowledge
DADU regulations are our specialty, not a side project. We stay current on every code update and permitting requirement in your area, translating complicated legal language into clear, actionable steps. When regulations change, you don’t have to worry—we already know about it.
Informed Customer
We believe the key to turning stress into confidence is through information and education. The more educated and empowered you are about the process, the more relaxing, enjoyable, and even exciting the entire journey becomes. That’s why we place strong emphasis on clear and proactive communication, so you can make informed decisions with peace of mind.
Speed Without Delays
Our experienced team submits complete, accurate applications the first time, anticipates every possible requirement upfront, coordinates seamlessly with city departments, and stays proactive at every stage from initial filing through final approvals. Keeping your project moving forward as fast as the city allows, so you avoid unnecessary setbacks and hit your timeline with confidence.
Vasiliy Frantsevich
Owner & Founder
With over 10 years in real estate and construction, Vasiliy recognized that homeowners needed someone who truly understood the complete DADU process. He has seen the same frustration repeatedly: homeowners with prime backyard space missing out on huge opportunities simply because zoning rules, permitting process, and site challenges feel overwhelming.
That gap drove him to start Modera Services. His in-depth knowledge of local regulations, proven track record with permits, and hands-on construction experience allow him to guide you confidently from feasibility to finished build, eliminating confusion and turning your unused space into real financial and lifestyle benefits.
