Retainer Agreement
Ref: 2026-001 • Standard Business Template
1. Engagement and Reserved Capacity
The Client hereby engages the General Contractor (GC) to remain on retainer to provide priority construction management, consulting, and maintenance services. The GC shall reserve [Number] hours per calendar month specifically for the Client’s needs. These hours cover administrative oversight, site visits, and minor repairs.
2. Retainer Fee and Payment
The Client shall pay a monthly non-refundable retainer fee of $[Amount], due on the first day of each month. This fee covers the reserved capacity and the initial block of hours. Any work performed beyond the reserved hours will be billed at an 'Overage Rate' of $[Amount] per hour.
3. Priority Response and Availability
By maintaining this retainer, the Client is granted 'Priority Status.' The GC guarantees a communication response within [Number] hours and on-site mobilization for non-emergency assessments within [Number] business days. Failure to maintain the retainer waives the Client’s right to priority scheduling.
4. Unused Hours and Rollover Policy
To ensure the GC can manage labor schedules, unused hours do not roll over indefinitely. A maximum of [10% or 5 hours] may be carried over to the following month. Any hours not used by the end of the term or exceeding the rollover limit are forfeited to compensate the GC for the reserved availability of the crew.
5. Excluded Services (Scope Boundaries)
The retainer is for ongoing management and minor works. It explicitly excludes: (a) Capital projects exceeding $[Amount] in total value; (b) Structural engineering or architectural design fees; (c) Emergency remediation requiring 24/7 onsite presence for more than 48 hours. Such projects will require a separate, standalone Construction Contract.
6. Termination and Cancellation
Either party may terminate this Retainer Agreement with [30/60] days' written notice. If the Client cancels without the required notice, the final month’s retainer fee shall be forfeited as a 'Scheduling Disruption Fee' to compensate the GC for lost opportunity costs.
Capacity Cannibalization
Without a retainer, an 'on-call' client might demand immediate service, forcing you to pull labor from a high-profit project and incurring liquidated damages.
Subcontractor Churn
Losing your best specialized subs because you can't guarantee them a minimum monthly workload, which a retainer structure would otherwise fund.
Unpaid Pre-Construction
Spending dozens of hours on site inspections, estimating, and sourcing for a client who eventually moves the project to next year without paying for your time.
What is a General Contractor Retainer?
A General Contractor Retainer is a formal agreement where a client pays a recurring monthly fee to secure a GC's priority availability and a set number of service hours. It ensures the contractor is compensated for 'readiness,' covers ongoing administrative oversight, and provides the client with guaranteed response times.

Why General Contractors need a clear retainer
In the construction industry, your most valuable asset is your capacity. Without a General Contractor Retainer, you are at the mercy of project-to-project volatility, often leaving your best subcontractors idle or your office staff overwhelmed with unbilled administrative work. This document transforms your business from a commodity bidder into a strategic partner. It ensures that your 'readiness' has a price tag. For a GC, a retainer covers the 'death by a thousand cuts'—the site visits, vendor coordination, and pre-construction advice that typically go unpaid. It provides the predictable cash flow necessary to retain top-tier talent and cover fixed overhead regardless of permit delays or weather. By formalizing availability, you eliminate the expectation of immediate response without compensation and create a sustainable, professional boundary that protects your profit margins and your sanity.
Real-world scenario
Jim, a GC specializing in commercial retail, was tired of clients calling him for 'emergency leaks' that resulted in 2 hours of work but 6 hours of coordination, often unbilled. He implemented a $2,500 monthly retainer for his top three mall tenants. Six months later, a major pipe burst at a flagship store. Because the retainer was in place, Jim’s crew was already 'on-call' and arrived in two hours. The client was happy because they had 'VIP access,' and Jim was happy because even in the quiet months when no leaks occurred, the retainer covered his project manager's salary. He stopped chasing small invoices and secured $90,000 in guaranteed annual revenue before a single project contract was even signed. The retainer turned his reactive 'handyman' headaches into a proactive, high-revenue management service.

Frequently Asked Questions
How do I handle materials under a retainer model?
Materials should never be included in the retainer fee. The retainer covers labor and expertise. Materials should be billed separately via a 'Change Order' or a 'Cost-Plus' reimbursement schedule with a standard markup.
What happens if I'm too busy to fulfill the retainer hours?
The agreement should include a 'Contractor Capacity' clause. If you cannot meet the priority response time, the client usually receives a pro-rated credit toward the next month or a partial refund of that month's readiness fee.
