2026 Investment Guide
ADU pricing depends on the type of unit, existing conditions, utilities, permits, site work, selections, and how the space will be used. A realistic ADU investment should account for architecture, Title 24 energy work, structural or civil coordination when needed, utility and sewer planning, permit support, construction, and durable finish selections.
Conversion Scope
Converts an existing garage or similar footprint into livable space. This can move faster than a new detached structure when the slab, utilities, access, and existing conditions cooperate.
Compact Living
A compact unit within the existing home, often 500 square feet or less, with its own entrance and careful planning around privacy, circulation, and shared systems.
Lars Fit
A new dwelling connected to the main home. Design, structural planning, utilities, Title 24, permits, selections, and construction coordination shape the final investment.
New Structure
A full stand-alone dwelling with its own foundation, envelope, utilities, kitchen, bath, and site work. Detached ADUs usually drive the highest return and the most planning complexity.
These ranges are planning references, not estimates for a specific project. Every property is different, so accurate pricing requires feasibility review, design scope, site conditions, and proper planning before numbers should be trusted.
Before You Compare ADU Quotes
A lower ADU quote may leave out design, permit revisions, utility work, Title 24, site conditions, or finish selections. Lars helps you compare the full investment against the rental income, family use, and long-term value you want from the unit.
For contract basics, CSLB recommends a detailed written agreement with scope, payment schedule, permit responsibility, completion timing, change-order terms, and license information. Review CSLB contract guidance.
ADU Types
Every ADU type solves a different problem. Lars helps you compare buildability, privacy, cost, rental potential, and approval path before committing to a design direction.
A separate backyard or side-yard dwelling for rental income, multigenerational living, guests, or long-term property flexibility.
A new unit connected to the main home, planned around privacy, access, fire separation, utilities, and the existing structure.
A smaller unit created within the existing home, often useful when the goal is efficient living space without a full detached build.
A conversion of existing garage space into a permitted living unit, with careful review of slab, ceiling height, utilities, and code upgrades.
Permits, Law & Local Review
ADU rules are one of the strongest reasons to work with a local design-build team. State law, City of San Diego standards, coastal or fire conditions, utilities, HOA review, and parking context can all affect what is realistic on your lot.
Useful official references: California HCD ADU Handbook and City of San Diego ADU Bonus Program.
State ADU law supports ministerial review for eligible ADUs, meaning qualified projects may be reviewed against objective standards rather than a discretionary hearing path.
California has limited many local owner-occupancy requirements for ADUs, but project-specific rules should still be checked before design assumptions are locked in.
The City of San Diego offers an ADU Bonus Program tied to deed-restricted affordable units, with additional flexibility in Transit Priority Areas when applicable.
Parking, HOA review, coastal location, fire access, sewer, utilities, and lot conditions can all affect the path. Lars treats those as early feasibility items.
ADU Architect & Design-Build
An ADU is both a small home and a site-planning puzzle. With Lars, you do not have to hire a separate ADU architect, designer, estimator, and contractor and hope the handoffs work. Our design-build team plans the unit, reviews constraints, coordinates permits, and builds the project under one accountable process.
Best fit for homeowners who want:
Our ADU architect and design team help shape the unit before construction pricing, so layout, privacy, utilities, and scope are aligned early.
Architecture, interior design, estimating, permit coordination, and construction live under one accountable process instead of separate handoffs.
We help homeowners think through privacy, durability, entry sequence, storage, and livability so the ADU supports family use or rental goals.
Lars coordinates permit submittals, city comments, revisions, and inspections when they apply to your ADU scope.

California has limited many local owner-occupancy requirements for ADUs, but the right answer depends on the unit type, timing, local rules, and how the property will be used. Lars reviews this during early feasibility.
HOA documents may include reasonable design or review requirements, but California law limits rules that effectively prohibit or unreasonably restrict eligible ADUs. We recommend checking HOA requirements early.
Rental income depends on location, size, parking, privacy, finishes, lease terms, and current market conditions. We design ADUs with long-term livability and durability in mind rather than promising a fixed rent number.
Detached ADUs usually offer more privacy and rental flexibility, while attached ADUs may work better for constrained lots or family use. The best choice depends on your lot, budget, goals, and approval path.
