Professional ADU Feasibility, Preconstruction Planning, Budget Analysis, and Timeline Guidance for Homeowners and Investors in Moreno Valley, Riverside County, and the Inland Empire
Building an Accessory Dwelling Unit (ADU) is a major financial and regulatory decision. Zoning requirements, site constraints, utility capacity, and permitting timelines can vary significantly from one property to the next.
Pendleton Construction provides paid ADU feasibility and preconstruction planning services designed to help homeowners and investors understand whether an ADU is realistically achievable before committing to architectural design, engineering, or construction.
Our process focuses on clarity, risk awareness, and informed decision-making – not free estimates or sales-driven assessments.

Why We Don’t Offer Free ADU Assessments
Many contractors advertise free ADU assessments. In most cases, these are informal site visits intended to sell construction services rather than evaluate feasibility.
We take a different approach.
Early ADU decisions carry real financial, regulatory, and design risk. Our clients rely on documented analysis,
realistic budget ranges, and honest constraints – not assumptions.
A paid ADU feasibility review allows us to:
- Evaluate zoning and ADU regulations at a high level
- Identify potential site limitations and access issues
- Provide realistic budget and timeline expectations
- Document assumptions and risks clearly
- Offer unbiased guidance, even if the recommendation is not to proceed

ADU FAQs – Moreno Valley, Riverside County, and the Inland Empire
These are common preconstruction questions we address before clients invest in architectural design or engineering.
Local requirements vary by jurisdiction and are administered by your city or county building department.
Do I need a building permit to build an ADU?
Yes. ADUs require plan review and building permits through the local Building & Safety Division (city or county). Submittal requirements and processing expectations vary by jurisdiction.
Can I build an ADU on my property in Moreno Valley or the Inland Empire?
Many residential properties can add at least one ADU, subject to local standards and site constraints. The fastest path is confirming zoning, setbacks, access, and utility constraints with your city or county building department.
Do I need a new address for an ADU?
Often, yes – especially for detached ADUs. Address assignment rules can differ by jurisdiction (city vs unincorporated county). We flag this early so it doesn’t surprise you later.
How long does ADU approval take?
Approval timelines depend on jurisdiction and whether your submittal is complete. Missing items commonly restart review timelines. We focus on feasibility and completeness so your next steps don’t stall.
What’s the difference between an ADU and a JADU?
ADUs and JADUs are different unit types with different constraints (size, configuration, and requirements). Your best option depends on your property and objectives, which we evaluate during feasibility.
What usually makes an “easy ADU” turn into a problem?
Access limitations, utility constraints, grading/hillside conditions, and jurisdiction-specific requirements. These are exactly the risk areas we identify before you spend money on plans.
What should I do before I pay for architectural drawings?
Confirm basic eligibility and constraints first (zoning, setbacks, utilities, access, grading). Then do a feasibility review so your design is grounded in reality instead of assumptions.
