Roseville is one of the more straightforward Sacramento-area cities for adding an accessory dwelling unit, or ADU, which is a small self-contained home built on the same lot as a main house. The city’s large stock of 1970s-1990s suburban homes on generous 7,000-10,000 sq ft lots gives most homeowners real room to work with. But Roseville has its own permitting path, its own design standards, and its own quirks with older electrical panels that change the budget. We’re Lodgewick ADU Builders, part of the Kingswell family of home-service companies, and we handle accessory dwelling units, garage conversions, and home additions across Roseville.

Why Roseville Homes Are Different
Roseville’s housing stock tells a story you won’t see in older Sacramento neighborhoods. Most homes here were built between 1970 and 2010, with wood-frame construction, stucco or siding exteriors, and slab-on-grade foundations. They sit on lots large enough for a detached ADU in the rear yard, but setbacks and utility access often dictate where the unit can actually go. In neighborhoods like Cherry Glen and Cirby Ranch, the original 100-amp electrical panels were sized for one household. Add a separate ADU and you’re almost always looking at a panel upgrade or a separate service drop, an extra $3,000-$6,000 many homeowners don’t see coming.
Climate is the other factor that changes how we build here. Roseville summers regularly push past 100°F, so energy-efficient design isn’t optional. We spec high-insulation walls, cool roofs, and shaded outdoor areas as standard. Winters are mild with occasional frost, which means freeze protection for plumbing matters less than it does in colder regions, but it’s still worth doing right. The city has worked to streamline ADU approvals as a response to rising housing costs, yet design standards remain strict to protect neighborhood character. That combination, easier permits but real design rules, is exactly where a local ADU builder earns their keep.
Our Main Roseville Services
Roseville homeowners call us most often about two things, adding a new ADU and converting an existing garage into living space. Each has its own dedicated Roseville page below with pricing, timelines, and what to expect, or start with the home page for the full picture.
Home Addition Contractor in Roseville
A home addition in Roseville means extending the footprint of a house that was built for a smaller household. Most of these homes have the lot space for a ground-floor extension, but tying a new slab to an existing slab-on-grade foundation takes care and experience. Roseville’s hot summers also mean the new space needs its own HVAC sizing, or it’ll bake in July. We handle design, permits, foundation work, framing, and finishes under one written contract. Our Home Addition Contractor in Roseville page covers pricing and the full process.
Garage Conversion Contractor in Roseville
A garage conversion, turning an existing attached or detached garage into a livable room or ADU, is often the fastest way to add square footage in Roseville. Homes here have garages built alongside the main structure, which usually means the foundation and roof are already in place. The work centers on insulation, electrical, drywall, flooring, and adding proper windows and a bathroom where codes require. The one wildcard is the electrical panel, older Roseville panels frequently need upgrading before a conversion can pass inspection. Our Garage Conversion Contractor in Roseville page breaks out real costs.
ADU Builders in Roseville
Building a detached ADU, or accessory dwelling unit, which is a fully separate small home in the backyard, is the most involved of the three. Roseville’s tract layouts usually leave room for a rear-yard unit, but utility connections, setbacks, and fire access can constrain the footprint. We work with established prefab and panelized systems from brands like Abodu, Cover, and Dvele, matched to your lot and budget, then handle site work, foundations, and finish. Our ADU Builders in Roseville page has the full price breakdown.

What pushes a Roseville job toward the upper end of these ranges is usually site access, the condition of the existing electrical service, and whether the design needs custom engineering to meet the city’s neighborhood character standards. What doesn’t push the price up is a surprise we spring on you later. Every Lodgewick project comes with a written price before any work starts, no changes at the door, no add-ons you didn’t approve.

FAQs About ADU Company in Roseville
Roseville’s ADU permit process typically runs 3-6 months from submittal to issued permit, depending on design complexity and how quickly plan reviews come back. The city has streamlined ADU approvals in recent years, but site-specific issues like utility easements or neighborhood design review can add time. Call (279) 256-1973 and we’ll walk through your specific property.
Roseville has several HOA-governed neighborhoods, particularly in newer developments, and those HOAs can impose design and size restrictions beyond city code. State law limits HOA authority to ban ADUs outright, but setback, height, and appearance standards often still apply. We review your HOA’s CC&Rs before you commit to a design.
