ADU Design & Permit Plans in Danville

Every property is different, and choosing the right type of ADU in Danville can make a big difference in how well the new space works with the existing home.


Detached ADU
A separate backyard home that can provide more privacy and flexibility for family, guests, or rental use.


Attached ADU
An ADU designed as an addition to the existing home. We recently designed an 800 sq. ft., two-bedroom attached ADU in Danville, creating a casita-style living space while making efficient use of the property.


Garage Conversion ADU
An existing garage can potentially be converted into a permitted ADU, making use of space and a structure already on the property.


Junior ADU (JADU)
A smaller unit of up to 500 sq. ft. created within an existing single-family home.

For our Danville project, the attached ADU was the best fit because it gave the homeowners a private two-bedroom casita while still connecting naturally with the existing residence. We also designed around the property's available space and applicable ADU requirements, including the 4-foot side and rear setback standards that can apply to new ADU construction.


Whether you're considering an attached ADU, backyard ADU, garage conversion, or casita, we can help evaluate your property and prepare the ADU design and permit plans in Danville, including layout development, plan preparation, engineering coordination, and permitting assistance.

Additions & Remodels in Danville

Floor Plans & Layout Design

For our Danville full-home remodel, the focus was on looking at the house as a whole rather than changing just one room. We developed a new floor plan that reorganized the existing spaces and created a better flow between the main living areas, bedrooms, and bathrooms.

This same approach guides our Danville remodel and addition plans understanding what can be improved within the existing footprint first, then exploring where additional space may make sense. From initial layouts to design and permit plans, we help turn an existing home into a space that better fits how the homeowner wants to live.

Exterior Elevations

With many Danville homes on sloped and hillside lots, exterior elevations are an important part of planning a remodel or addition. We prepare Danville design and permit plans showing rooflines, building heights, windows, doors, exterior finishes, and how the proposed addition works with the existing home and site.

For hillside projects, we also consider changing grades and site conditions to create clear remodel and addition plans for permit review.

Setbacks & Buildable Space

Many Danville homes sit on larger lots, which can create great opportunities for home additions, bedroom or bathroom expansions, and larger remodels. With more available side and rear yard space, there may be greater flexibility when exploring where an addition can fit.


We review the property's zoning, setbacks, lot layout, and existing home to determine the available buildable area before developing your Danville addition and permit plans.

Danville Home Design & Permit FAQs

Please reach us at patricia@designsbyorigami.com if you cannot find an answer to your question.

Most projects involving structural changes, additions, or significant plumbing, electrical, or mechanical work require permits. The Town specifically lists residential additions, ADUs, and many remodels among projects requiring permits. We can prepare the Danville design and permit plans and coordinate the drawings needed for submittal.

Many Danville residential properties can accommodate an ADU, but the design depends on the lot and existing home. Current Town guidance generally allows 4-foot side and rear setbacks for qualifying attached and detached ADUs, while front setbacks depend on the property's zoning district.


They can. Danville states that a geotechnical (soils) report and engineering geology report are required for grading projects in hillside areas. This is something we like to identify early because the site conditions can affect the foundation, grading, structural design, and overall permit package. 


We typically start by documenting the existing home and understanding what you want to change. From there, we review the property, zoning and setbacks and develop the proposed floor plan, site plan, elevations, and other drawings needed for the project. Danville maintains separate submittal requirements for residential additions and remodels, so the final permit package depends on the scope of work.
