ADU Construction in Sacramento with LNL Construction

Building an Accessory Dwelling Unit (ADU) involves far more than most homeowners initially expect. Between navigating permits, zoning regulations, and coordinating multiple contractors, the process can quickly become overwhelming. LNL Construction is a Sacramento-based ADU contractor that manages the entire process — from design through final construction — helping homeowners avoid costly mistakes and unnecessary delays.

The company was founded by Landon Linville, who brings over 30 years of experience in the construction industry. That depth of experience shapes how LNL Construction approaches each project, with an emphasis on clear communication, honest timelines, and a well-defined scope of work. Understanding the stress that comes with ADU construction, they prioritize keeping clients informed at every stage.

LNL Construction offers a free site visit to provide an initial overview of expected costs, covering basic materials, labor, and general scope of work. For those who need more detailed planning, a design-phase estimate is available for an additional fee. This includes in-depth analysis, precise measurements, and custom specifications tailored to the specific project.

Types of ADUs LNL Construction Builds

LNL Construction works with a range of ADU types, allowing homeowners to choose the option that best fits their lot size, proximity to the main residence, and personal needs. The following ADU types are among those they build:

1. Backyard Cottage: A detached ADU builder option, ideal for guests or extended family.
2. Garage Conversion: A garage conversion contractor service that transforms an existing garage into a fully livable space.
3. Detached ADU: A separate structure offering maximum privacy and flexibility on the property.
4. Attached ADU: Built onto the existing home, sharing utilities for added convenience.
5. In-Law Suite: An in-law suite builder solution designed for extended family or aging parents.
6. Junior ADU (JADU): A smaller unit built within the existing home's footprint, offering an independent living area.
7. Tiny Homes: Compact, standalone structures with everything needed in a smaller footprint.
8. ADU Design-Build: A fully custom-designed accessory dwelling unit tailored to specific preferences.

For homeowners who prefer to avoid a lengthy on-site build, LNL Construction also offers prefab ADU options. These units are constructed off-site in sections within a controlled environment, then delivered and assembled on the property. This approach typically results in less disruption, a more predictable timeline, and consistent build quality.

The cost of building an ADU in Sacramento typically ranges from around $150,000 for smaller, basic units to over $300,000 for larger, custom-built ADUs with high-end finishes. Factors such as unit size, ADU type, materials, and lot characteristics all influence the final cost. A detailed site assessment is necessary to arrive at an accurate estimate.

Sacramento also has specific ADU regulations that must be followed, including zoning rules around setbacks, minimum lot sizes, and parking requirements. Permits are required and cover construction plans, utility hookups, and safety compliance across plumbing, electrical, and structural systems. Working with an experienced ADU contractor familiar with Sacramento's local codes can help streamline this process and reduce the risk of unexpected costs.
