Factors Influencing ADU Permit Costs

The cost of obtaining an ADU permit in Tulare can vary based on several factors. Understanding these factors will help you better estimate your expenses.

Size of the ADU

The size of your ADU is a significant determinant of permit costs. Larger units typically require more extensive reviews and higher fees.

What Tulare's current code and California law say about your ADU permit costs

The ranges above are general estimates. The rules that actually decide what you pay, and how much design work your permit needs, are in Tulare's ADU ordinance and in California's ADU law. Tulare's current standards are in Municipal Code Section 10.60.030, adopted by Ordinance 2025-01 in January 2025. City fees themselves are set in the City's Master Fee Schedule, which the City Council reviews and approves, so ask the Building Permit Center for a current quote before you budget.

Tulare's ADU standards in brief

  • Where ADUs are allowed: on lots in the R-1, R-M, and R-H zones with an existing home, or with a main home built at the same time as the ADU.
  • How many: a single-family lot can have one ADU plus one junior ADU (JADU). A lot with an existing multifamily building can have two new detached ADUs and at least one conversion ADU, with conversions allowed up to 25 percent of the existing units, rounded up.
  • Size: up to 1,200 square feet. An attached ADU can be up to 800 square feet or 50 percent of the main home's existing living area, whichever is more.
  • Setbacks: at least 4 feet from side and rear lot lines in every zone. Lot coverage, floor area ratio, open space, and minimum lot size rules cannot block an ADU of up to 800 square feet.
  • Height: the ordinance applies the height rules of your zone district. State law, in Government Code Section 66321, separately guarantees at least 16 feet for a detached ADU on a lot with a single-family or multifamily home.
  • Parking: no off-street parking is required, and garage or carport spaces removed to create an ADU do not have to be replaced.
  • Owner occupancy: not required for an ADU.
  • Utilities: water, sewer, and other utilities must be provided as the City's building official determines.

Fees California law limits

California's Government Code Section 66311.5 (renumbered from Section 66324 on January 1, 2026) caps several of the charges that can add up on an ADU permit:

  • Impact fees: no impact fee can be charged on an ADU of 750 square feet of interior living space or less, or on a JADU of 500 square feet or less. Above 750 square feet, impact fees must be proportional to the square footage of the main home.
  • School fees: an ADU or JADU with less than 500 square feet of interior living space is treated as construction that does not trigger school impact fees.
  • Utility connections: an ADU is not counted as a new residential use for water and sewer connection fees or capacity charges unless it is built with a new single-family home. A conversion within an existing home or accessory structure cannot be required to have a new separate utility connection. A new detached ADU can be, but any connection fee must be proportionate to the unit's burden on the system and cannot exceed the reasonable cost of the service.

This is one reason a 750-square-foot plan often costs less to permit than a slightly larger one, and why converting an existing garage usually has lower fees than building new.

Pre-approved plans can cut design costs

Tulare offers ADU plans that architects and designers have submitted to the City and that have been pre-approved to meet state and local requirements. The City's ADU page currently lists four:

  • a 360-square-foot studio,
  • a 484-square-foot one-bedroom,
  • a 748-square-foot two-bedroom, and
  • a 1,200-square-foot three-bedroom.

To use one, call the Community Development Department at (559) 684-4276. Staff will put you in touch with the plan's architect, and you will need a release and waiver signed by that architect. You still fill out the City's Property Owner Application Package and get all building permits before construction. The 748-square-foot plan stays under the 750-square-foot impact fee threshold.

Submitting and tracking your permit

Applications can be submitted in person at City Hall, 411 E. Kern Avenue, Tulare, CA 93274, or through the City's Building Digital Plan Submission page. The Building Permit Center is open Monday through Friday, 8 a.m. to 5 p.m., at (559) 684-4218, but City Hall payment windows close at 4 p.m. Under California's Government Code Section 66317, as amended for 2026, the City must tell you in writing within 15 business days whether your application is complete, and list anything missing. Once it is complete, and there is already a home on the lot, the City must approve or deny it within 60 days. A denial must come with a full written list of what is deficient and how to fix it, and you can appeal.
