How Our Process Works

You begin with a site evaluation to confirm your property can accommodate an ADU within zoning and setback limits. In Lowell, this often involves checking utility access, drainage patterns, and easement restrictions before design work begins. Once feasibility is confirmed, you review layout options tailored to your intended use, whether that's housing a family member, creating a rental unit, or adding a home office.

Sor Construction Corp helps clients navigate zoning, lot limitations, design considerations, and permitting steps associated with ADUs. All new units meet inspection and code requirements. Permitting coordination includes submitting plans, scheduling reviews, and addressing any feedback from local officials to keep your timeline moving forward without unnecessary delays.

Construction proceeds with framing, utilities, insulation, and finish work managed in phases, with inspections scheduled at key milestones. You receive updates as each stage completes, and final walkthroughs ensure everything from electrical outlets to door hardware functions as expected before you take occupancy.

Details That Matter Most

Clients planning ADUs often ask about costs, timelines, and what makes a unit viable for long-term use or rental income in the local market.

What size ADU can I build on my property?
Size depends on lot dimensions, setback requirements, and local zoning rules. Most properties in Lowell accommodate units between 400 and 800 square feet, though larger lots may support more.
How long does ADU construction typically take?
From permit submission to final inspection, most projects take four to six months, depending on design complexity and weather conditions. Permitting alone can take several weeks.
Do I need separate utilities for an ADU?
Not always. Many units tie into existing water, electric, and sewer lines, though upgrades may be needed to handle increased load. Your site evaluation will clarify what's required.
Can I use an ADU as a rental property?
Yes, as long as local regulations permit rentals and your unit meets all safety and habitability codes. Many clients build ADUs specifically for rental income or short-term leasing.
What happens if my lot has drainage or grade issues?
Grading adjustments, French drains, or retaining walls can address most drainage concerns. These are identified during site evaluation and included in your project plan.

Whether you're adding space for aging parents, creating a rental unit, or building a private office, an ADU offers flexibility without the cost or hassle of moving. Book a site evaluation to confirm your lot's potential and start designing your new space.
