What is planned at Mercury Lane and Berry Street in Brea?

If you’re looking at a home near Mercury Lane and Berry Street, the vacant corner raises a practical question: what’s approved there? The answer is Mercury Senior Apartments, an 85-unit apartment community with all 85 units affordable to lower-income households.

The October Council actions dealt with clearing the old plan’s recorded documents and approving bond financing; neither confirms construction has started.

This guide is educational, not legal or tax advice.

What is approved for the corner?

The City of Brea approved Mercury Senior Apartments at the southeast corner of Mercury Lane and Berry Street, on a site the October 6, 2026 staff report describes as vacant and unpaved.

The parcel is 1.01 acres, identified as Assessor’s Parcel Number 296-143-01. It sits within the Brea Core Specific Plan area and carries the “Mixed Use 50” designation in both that plan and the Brea 2050 General Plan.

C&C Development Co., LLC is the developer. Ordinance No. 1278 identifies Brea Mercury LP as the current site owner. The City’s stated tenant selection policy will prioritize seniors and/or veterans, as well as those employed in or residing in Brea.

On August 19, 2025, the City Council approved Density Bonus No. 2025-01 through Resolution No. 2025-057, an Affordable Housing Agreement, a Loan Agreement and an Addendum to the Final EIR. Those approvals appear in the background to October 6 item 4A.

Why is this project connected to Greenbriar?

Mercury Senior Apartments serves as the off-site affordable housing component of the Greenbriar Residential Development Project.

On April 1, 2025, the Council approved Greenbriar’s Development Agreement through Ordinance No. 1258. That agreement allows affordable units to be built off site to satisfy Greenbriar’s affordable housing requirement, consistent with Brea City Code Section 20.40.050.B.

The Greenbriar applicant, Lennar Homes of California, LLC, identified the Mercury Lane site and C&C as its partner. That connection explains why the Mercury project appears in the City’s discussion of another development.

The City’s financial participation consists of a Housing Trust Fund loan and development impact fee deferral, approved August 19, 2025. The project also received low-income housing tax credits from the California Tax Credit Allocation Committee on May 12, 2026, and Orange County Board of Supervisors approval for Supportive Housing funding on September 15, 2026.

What happened to the older 114-unit plan?

The older Mercury Lane Residential Planned Community was never constructed, and its recorded agreements prompted the current title cleanup.

Approved June 2, 2020 through Ordinance No. 1214, that proposal was a five-story, 114-unit building. It included 11 low-income units, 80 workforce units and 23 market-rate units. The City attributes its failure to proceed to changing circumstances, including the Covid-19 pandemic.

The five-story description belongs to that earlier proposal. The City records Insider reviewed do not state the height of the approved 85-unit project.

The older Development Agreement No. 19-01, or DA 19-01, was recorded in Orange County’s Official Records on September 1, 2020 as Document No. 2020000458788. Two additional documents were recorded April 25, 2022:

• An Affordable Housing Agreement, Document No. 2022000193475, covering affordable units for 55 years plus a Brea workforce preference program.
• A Restrictive Covenant for Workforce Housing, Document No. 2022000193474, covering affordable units for 40 years plus a Brea workforce preference program.

These are the prior project’s documents. The staff report says their proposed cancellation does not modify the current project’s approved entitlements.

Why did the Council consider clearing title?

The developer requested cancellation because DA 19-01 remained on the site’s title report, and its lenders and tax credit investor required the prior project’s documents to be cleared.

That requirement came from the construction lender, permanent lender and tax credit investor. It concerned DA 19-01 and the older affordable housing covenants.

On September 8, 2026, the Planning Commission recommended cancellation through Resolution No. PC 2026-07 by a 5-0 vote. On October 6, item 4A, the Council introduced Ordinance No. 1278 and authorized the City Manager to execute the cancellation and both termination documents. That motion also passed 5-0.

Ordinance No. 1278 was on the October 20, 2026 consent calendar for adoption. Insider has not seen the October 20 minutes, so adoption remains unverified.

An owner thinking of selling a home near the corner might open the October 6 packet to understand what a buyer could ask about the site. They would see that the 114-unit plan’s recorded documents are being cancelled, while the approved project is the 85-unit Mercury Senior Apartments. Reading further, they would find that first permit issuance was only a target. They could use those distinctions to describe what the packet confirms without treating the older plan or the permit target as the project’s current status.

What does the bond approval mean?

The Council approved issuance by the California Municipal Finance Authority of up to $60,000,000 in bonds solely for the purposes of satisfying TEFRA, the Code and California Government Code Section 6500, with repayment solely the borrower’s responsibility.

At October 6 item 4B, the Council held a hearing under the Tax and Equity Fiscal Responsibility Act, or TEFRA. It then adopted Resolution No. 2026-66 by a 5-0 vote, approving issuance by the California Municipal Finance Authority for the benefit of Mercury Brea LP.

The financing covers acquisition, construction, improvement and equipping of the senior multifamily rental housing project. The resolution’s approval was solely for satisfying TEFRA, the Code and California Government Code Section 6500.

The hearing lets the community speak for or against using tax-exempt bonds to finance the project. It doesn’t establish a construction start.

The City’s fiscal impact statement says the City has no financial, legal or moral obligation, liability or responsibility for the project or repayment. Financing documents will state that the bonds are not obligations of Brea or California and are payable solely from borrower-provided funds.

The Voice of OC story about the bond action provides a local news reference. The financing details here come from the City packet.

Say a buyer considering a home near the corner reads about the bond approval and wonders whether it confirms construction is starting. The City packet would show that the approval concerns financing for the apartment project and that repayment is solely the borrower’s responsibility. The buyer would also see that the City has no obligation for the project or bond repayment. Those financing details do not establish a construction start, and permit issuance remains unverified.

What can you check before buying or selling nearby?

The City’s agendas and packets show later Council actions on the ordinance and the project; for permit status, ask the City.

Start with the Meetings and Agendas page. The October 20 packet includes the October 6 minutes as item 3A and the ordinance’s proposed adoption as item 3E.

The October 6 report says building plan check was underway and first permit issuance was targeted for October 2026. Insider has not verified permit issuance. The records also do not provide rents, income limits, unit sizes, amenities or an opening date.

For the cancellation hearing, notices went to owners within 500 feet and appeared in the Brea Star-Progress. Staff had received no public comments when the report was prepared; no public speakers addressed that hearing.

The short version

Mercury Senior Apartments is approved for 85 affordable units, while the October Council records address older title documents and bond financing.

Keep the current approval separate from the unbuilt 114-unit proposal. Check subsequent City records before treating the permit target or ordinance adoption as confirmed.
