California Prop 39: Charter School Facility Rights and District Duties

California’s Proposition 39 requires every school district in the state to share its existing facilities with charter schools that enroll at least 80 in-district students, and to provide space that is reasonably equivalent to the district’s other public schools. The rule is codified at Education Code 47614, with the operational details spelled out in Title 5 of the California Code of Regulations.¹ If you run or are starting a charter school, the law gives you a right to space. It also gives you a calendar you have to live by.

Who Qualifies for District Space

A charter school becomes eligible by projecting at least 80 units of in-district classroom average daily attendance. That means students who live within the district’s boundaries and who will receive classroom-based instruction, physically present under the direct supervision of a charter school employee.² Nonclassroom-based attendance generally does not count, though the district and charter school can agree to include the actual classroom hours of those students.

You do not need to already be open. A school still in the planning stage qualifies if it has identified at least 80 in-district students who are meaningfully interested in enrolling for the coming year.¹ A not-yet-open school must have its charter petition approved before March 15 of the year preceding the school year it is requesting space for. Below 80 ADA, the district may deny the request, though it is not forced to.

The Annual Request Timeline

Facilities under Proposition 39 are requested year by year. The process does not roll over automatically, even for a school that occupied district space the year before. Five deadlines run from the November before the target school year through the following May:³

November 1: The charter school submits a written facilities request to the district.
February 1: The district issues a preliminary proposal identifying the rooms and shared spaces it plans to allocate.
March 1: The charter school responds in writing with concerns, deficiencies, or counterproposals.
April 1: The district issues its final written offer.
May 1 (or 30 days after the April notification, whichever is later): The charter school tells the district whether it accepts.

The November 1 deadline is the one that bites hardest. Miss it, and the school loses its right to district facilities for the whole next academic year. The March 1 response matters almost as much: concerns raised there are preserved for later negotiation and, if necessary, for court. Silence at that stage lets the district finalize its offer without having to engage with objections you never put in writing.

The request itself has three parts: a projection of in-district classroom ADA, a written explanation of how you arrived at it, and supporting documentation. Operating schools usually rely on historical enrollment, current attendance trends, and waitlists. New or expanding schools gather signed interest forms from parents of in-district students; the regulations say this evidence does not need to be verifiable to exact arithmetical accuracy, but it does need to be real. If your program needs specialized space (a workshop, a lab, a kitchen for a culinary program), say so in the request so the district can match it.

What “Reasonably Equivalent” Space Looks Like

The core quality standard is that the facilities a district offers must place charter school students in conditions reasonably equivalent to those at the district’s other public schools serving similar grades.¹ The regulations build a comparison group of district schools at similar grade levels and measure the offered space against several factors: capacity, condition of interior and exterior surfaces, electrical and plumbing systems, restrooms and drinking fountains, heating and cooling, and furnishings and equipment.⁴ A district cannot steer a charter school into its worst building if comparable schools are in better shape.

The analysis has to go beyond classrooms. In Ridgecrest Charter School v. Sierra Sands Unified School District, the Court of Appeal held that a district’s calculation of teaching-station square footage, standing alone, was incomplete; the district also had to account for contiguity and non-teaching station space.⁵ Charter schools are entitled to proportional access to shared spaces like multipurpose rooms, playgrounds, computer labs, libraries, and kitchens, with sharing schedules negotiated in good faith so neither program is unduly disrupted.

The space must also be contiguous: located on a single school site or immediately adjacent to it. Multi-site placement is allowed only if the charter school’s in-district ADA genuinely cannot fit on one site, and even then the district’s governing board must adopt a written statement of reasons explaining why.² The district also has to make reasonable efforts to place the school near the area it intends to serve and may not move it unnecessarily.

Finally, the facilities must be furnished, equipped, and ready for occupancy at least ten working days before the first day of instruction. “Equipped” covers furniture, machinery, and major software programs comparable to what the comparison group schools have.³

What Districts Are Not Required to Do

Proposition 39 is a sharing law, not a building law. A district is not required to lease, purchase, or build new facilities, and the statute specifically says no district has to use unrestricted general fund revenues to rent, buy, or lease space for charter school students.¹ In a district with genuinely no spare capacity, a valid Proposition 39 claim does not force the district to go out and acquire more real estate. Districts also are not required to pay for physical modifications to match a charter school’s preferred grade configuration, though the parties can agree to share those costs voluntarily.⁴

What the Charter School Pays

Districts may charge a pro-rata share of facilities costs, and the formula is capped. The district divides its total facilities costs paid from unrestricted general fund revenues by its total square footage to get a per-square-foot rate, then multiplies by the square footage allocated to the charter school.⁶ Nothing above that amount can be charged for use of the space. Because the rate is based on actual costs from the prior fiscal year, it resets annually.

After the charter school accepts the offer, the two sides sign a facilities use agreement. At a minimum it has to carry forward the terms of the district’s final notification and add several required provisions: general liability insurance from the charter school naming the district as additional insured, a reciprocal hold-harmless clause, and first-party property insurance maintained by the district on the allocated space.³

Day-to-day operations and maintenance are the charter school’s responsibility. The district keeps deferred maintenance and the replacement of furnishings and equipment it supplied, on its normal replacement cycle. All facilities, furnishings, and equipment the district provides remain district property.⁷

The Penalty for Over-Projecting Enrollment

Charter schools that project more students than show up pay a penalty. If actual in-district classroom ADA falls short of the projection by more than 25 ADA or 10 percent of the projection (whichever is greater), the excess space is treated as over-allocated and the charter school reimburses the district at a statewide per-pupil cost-avoidance rate the California Department of Education updates each year.⁸ The formula builds in a small cushion by subtracting half the threshold amount before calculating the final reimbursement, so a minor shortfall triggers nothing. Actual ADA for this purpose is set at the second principal apportionment, which gives schools some early warning. First-year schools are exempt from the over-allocation reimbursement, though they still pay the standard pro-rata share.⁴

If the District’s Offer Falls Short

The regulations push both sides toward good-faith negotiation during the February-through-April exchange of proposals and counterproposals. When that process fails, the main recourse is litigation. Ridgecrest is one example of a charter school successfully challenging an offer that did not account for contiguity and non-teaching station space.⁵ Timing is the problem: a lawsuit filed after the April 1 final offer may not produce a court order before the school year starts, which can leave the school without adequate space for months. Some charter schools file complaints with the California Department of Education, though its enforcement authority here is limited compared with a court order. Thorough written records at every stage, especially the March 1 response flagging deficiencies, are what make a later challenge viable.
