Costa Rica's construction industry is home to world-class contractors — and contractors who have never completed a project at the scale or quality level they propose to build. The challenge for foreign investors is that both may quote similar prices, present similar portfolios, and speak equally confidently. What separates them — almost entirely — is what's in the contract.

A strong construction contract is not just a legal document. It is a project management tool. A well-structured contract defines exactly what will be built, in what sequence, to what standard, by what date, and for what price. It defines how changes are handled, how disputes are resolved, and what happens if either party fails to perform. Without this clarity, disputes are almost inevitable.

Beyond the contract itself, two of the most powerful risk-reduction tools available to sophisticated owners are a milestone-based payment schedule — so money flows in proportion to verified progress — and direct procurement of key specialty items, so the most expensive, visible, and difficult-to-replace elements of the project are sourced, specified, and quality-controlled by the owner, not delegated to a contractor who may substitute lower-quality alternatives.

With more than 45 years of experience managing construction contracts, subcontractors, suppliers, and project delivery in Costa Rica, Papagayo Design Center has developed a system for structuring contracts and procurement that protects our clients' investments at every stage.

The Core Problem
Most construction disputes in Costa Rica trace back to three contract failures: no clear scope of work, no milestone-linked payment schedule, and no agreed change-order process. Any two of these missing is enough to derail a project.
45 Years of Experience
Papagayo Design Center has managed construction contracts for 300+ projects in Costa Rica — from single-family residences to five-star resort hotels. We've seen every failure mode and built systems to prevent them.

Section 01

Types of Construction Contracts

The contract structure you choose shapes your risk exposure, cost certainty, and administrative burden throughout the build. Each type is appropriate for different project stages and conditions.

Most Common
Lump Sum
Fixed Price Contract · Contrato a Suma Global

A single fixed price for a fully defined scope of work. The contractor bears the risk of cost overruns due to poor estimating or inefficiency. Changes to scope are handled through formal change orders at agreed unit rates.

Advantages for Owner
  • Maximum cost certainty
  • Contractor incentivized to work efficiently
  • Clear accountability for scope delivery
  • Simple administration when scope is fixed
Conditions Required
  • Complete drawings and specifications before signing
  • Clearly defined change-order process
  • Independent verification of milestone completion
Best for: Fully designed luxury residences, hotels, and commercial projects with complete construction documents.
Flexible Scope
Cost Plus
Time & Materials · Administración Delegada

The owner pays actual costs (labor, materials, subcontractors) plus an agreed contractor fee — either a fixed fee or a percentage of costs. The owner has full transparency but bears the risk of cost increases.

Advantages for Owner
  • Full cost transparency — open books
  • Useful when design is still evolving
  • No contractor contingency built into price
  • Flexible scope changes without renegotiation
Risks to Manage
  • No cost ceiling — requires intensive oversight
  • Contractor has less incentive to work efficiently
  • Requires qualified project manager on site
Best for: Early-stage work, projects still in design development, or complex renovations where scope cannot be fully defined upfront.
Infrastructure & Earthwork
Unit Price
Price per Measured Quantity · Precio Unitario

The contractor is paid a fixed price per unit of work (per cubic meter of earth, per linear meter of pipe, per square meter of concrete). Total cost depends on actual measured quantities completed.

Advantages for Owner
  • Fair payment for actual quantities done
  • Appropriate where volumes cannot be pre-determined
  • Easy to verify and audit
  • Natural fit for earthwork and infrastructure
Risks to Manage
  • Total cost is variable — requires quantity tracking
  • Requires independent quantity verification (quantity surveyor)
  • Not suitable for finish work or complex assemblies
Best for: Site development, earthwork, road construction, underground utilities, retaining walls, and infrastructure with uncertain quantities.
Section 02

Milestone-Based Payment Schedule

The payment schedule is your primary leverage throughout construction. Money should flow in proportion to verified, completed work — never ahead of it. Below is a typical structure for a luxury residential project.

  • 01
    Mobilization Deposit
    Contract signing, insurance, site security, and temporary facilities established. Verify contractor's CFIA registration and insurance before payment.
    10%
  • 02
    Site Work & Foundations
    Excavation, foundation rebar and form inspected, concrete poured and cured, engineer sign-off obtained.
    10%
  • 03
    Structural Frame
    All columns, beams, slabs, and structural walls completed and inspected. Structural engineer certification.
    15%
  • 04
    Roof Structure & Enclosure

    15%
  • 08
    Systems Commissioning
    All MEP systems operational and tested. HVAC, electrical, plumbing, home automation, and security operational.
    10%
  • 09
    Punch List & Final Handover

    10%
Payment Summary
Mobilization10%
Construction phases (01–07)70%
Commissioning10%
Final retention10%
Key Rule
Never pay more than 10–15% ahead of verified completed work. The contractor should always be working with your money — not ahead of it. A project manager on site validates every milestone before any payment is authorized.
Final Retention
Hold the final 10% until: occupancy permit obtained, all punch list items resolved, as-built drawings delivered, and all warranty documents provided. This is your most effective lever for ensuring full completion.
PDC Approach
As project managers, we verify every milestone physically before authorizing payment. Payments are never made based on contractor self-reporting — only on verified completion confirmed by our team on site.
Section 03

Direct Client Procurement Strategy

One of the most powerful risk-reduction tools for luxury projects: the client directly purchases key specialty items. The contractor installs them — but the owner controls selection, source, and quality.

In standard construction practice, the general contractor purchases all materials and subcontracts all specialty work, then bills the owner at a markup. For commodity items like concrete, rebar, and block, this is efficient and appropriate. For high-value specialty items — windows, cabinetry, tiles, fixtures — it introduces significant risk.

When a contractor sources these items, they are typically incentivized to minimize cost, not maximize quality. Substitutions happen — often silently. The $12,000 window system you specified may arrive as a $4,000 product with a different performance profile. The tile you selected in Miami may be replaced with a local alternative that doesn't match. The kitchen you designed may arrive 30% shorter than planned.

Direct procurement eliminates this risk entirely. When the owner or their project manager purchases specialty items directly — from vetted international suppliers, local importers, or specialty fabricators — the selection, specification, and quality control remains with the person who has the most to lose if it's wrong.

The contractor's contract value is reduced for these items, and they are listed in the contract as Owner-Furnished, Contractor-Installed (OFCI) items. The contractor is still responsible for correct installation to manufacturer specifications — but they never touch the procurement decision.

This strategy also frequently results in meaningful cost savings, since the owner eliminates the contractor's markup (typically 15–30%) on the most expensive items in the project.

OFCI Protocol
All directly procured items must be listed in the contract as Owner-Furnished, Contractor-Installed with specific installation specifications. Contractor must sign off on delivery condition at receipt and is responsible for proper installation.
Timing is Critical
Custom windows, doors, and cabinetry from US or European suppliers typically have 12–20 week lead times. Orders must be placed during design development — not after the structure is built. A project manager coordinates delivery timing with construction progress.
PDC Service
We manage the full OFCI procurement process: vendor selection, specification writing, factory coordination, import logistics, on-site delivery management, and installation oversight for all owner-furnished specialty items.

Section 04

Contractor Red Flags

These are the warning signs most commonly observed before a construction project goes wrong. If you encounter two or more of these in a single contractor relationship, proceed with extreme caution.

01
No CFIA-Registered Professional on Staff
Costa Rican law requires all permitted construction to be directed by an engineer or architect registered with CFIA. A contractor who cannot name a CFIA-registered professional responsible for the project is operating outside the law — and your building permit will not be valid.
02
Requesting More Than 20% Upfront
A mobilization deposit of 10% is standard and reasonable. A contractor requesting 30%, 40%, or more before mobilization is either cash-strapped, using your money to finish another project, or has no intention of delivering. Once the money is transferred, your leverage disappears.
03
Bid Significantly Below All Others
In Costa Rica's construction market, a bid 20–30% below comparable offers almost always reflects missing scope, planned material substitutions, or a contractor who will hit you with change orders once work has started. Get a detailed line-item breakdown and have it reviewed by your project manager before accepting.
04
Resistance to a Detailed Written Contract
"We work on trust" or "we'll sort out the details as we go" are phrases that precede disputes. Any contractor who resists a detailed written contract — with scope, payment schedule, change-order process, and warranty terms — is a contractor who plans to exercise flexibility on terms you believe are fixed.
05
No Verifiable Reference Projects at Your Scale
A contractor who has built $200k homes is not necessarily capable of building a $2M residence. Visit completed projects. Speak to those owners directly. Ask specifically about budget adherence, schedule performance, and how the contractor handled problems when they arose.
06
No Formal Project Schedule
If a contractor cannot produce a phased construction schedule with milestone dates before signing, they are not managing the project — they're building it. A project with no schedule has no accountability for delivery timing, and delays will be absorbed entirely by the owner.
07
Subcontractor Management is Unclear
Most general contractors subcontract specialty trades: concrete, framing, MEP, tile, cabinetry. Ask who the subcontractors are, whether they are CFIA-registered where required, and how the contractor manages their work. An evasive answer means the contractor will not control quality on the most technically demanding parts of your project.
08
No Plan for Owner-Furnished Items
If you intend to directly procure specialty items (windows, doors, kitchen, tile), a qualified contractor will have a defined OFCI protocol and will contractually accept installation responsibility. A contractor who resists this arrangement may be primarily motivated by procurement markup rather than construction quality.
Section 05

Construction Warranties

Costa Rican law and professional standards establish a tiered warranty structure for construction projects. Every contract should make these explicit — and tie the final payment release to warranty document delivery.

10
Year Liability
Structural Integrity
Under Costa Rican law and CFIA regulations, the responsible engineer and architect carry legal liability for structural defects — foundations, load-bearing walls, slabs, beams — for 10 years after project completion. This is statutory; it applies regardless of what the contract says.
3
Year Warranty
Building Systems
Mechanical, electrical, plumbing, HVAC, roofing, and waterproofing systems should be covered by a 3-year workmanship warranty. Equipment warranties from manufacturers should be passed through to the owner with registration completed at handover.
1
Year Warranty
Finishes & Workmanship
Interior and exterior finishes — paint, tile, flooring, cabinetry, millwork — typically carry a 1-year workmanship warranty. The contractor is responsible for rectifying any defects that appear within the warranty period at no cost to the owner.

What your contract must include: A written warranty section specifying: the warranty periods for each category of work, the process for reporting defects, the contractor's obligation to remedy within a defined timeframe (typically 30–60 days), the owner's right to remedy at contractor's expense if not addressed, and delivery of all manufacturer warranties, operating manuals, and as-built drawings at final handover as a condition of final payment release. Never release the final retention payment until all warranty documents are physically delivered and equipment is registered.

Common Questions

Frequently Asked Questions

What type of construction contract is best in Costa Rica? +
For most luxury residential and hospitality projects, a Lump Sum (Fixed Price) contract tied to a detailed scope of work is the most protective structure for owners — provided the drawings and specifications are fully complete before signing. Cost-Plus contracts are useful when design is still evolving, but require very tight oversight. The key in any case is a contract with clear milestone definitions, payment schedules tied to verified completion percentages, a strong change-order clause, and explicit warranty provisions.
How should a milestone payment schedule be structured? +
A well-structured milestone payment schedule for a residential project typically follows: 10% mobilization deposit upon contract signing, then payments of 10–15% tied to verified completion of each major phase (foundation, frame, roof, MEP rough-in, exterior, finishes, commissioning). Never pay more than 10–15% ahead of verified work completion. The final 10% should be retained until the occupancy permit and all punch list items are resolved.
What warranties are contractors required to provide? +
Under Costa Rican law, CFIA-registered professionals carry legal liability for structural defects for 10 years. Your contract should additionally require: a 3-year warranty on building systems (MEP, HVAC, roofing, waterproofing), a 1-year workmanship warranty on finishes, pass-through of all manufacturer warranties, and delivery of all warranty documents and as-built drawings as a condition of final payment release.
What items should I procure directly instead of through the contractor? +
For luxury residential and hospitality projects, direct client procurement of high-value specialty items dramatically reduces cost and protects quality. Best candidates include: windows and doors, kitchen cabinetry and countertops, bathroom vanities and millwork, specialty tiles, specialty plumbing fixtures, MEP systems (HVAC, smart home, solar), light switches and outlets, door hardware, and decorative lighting. The contractor installs these items under an Owner-Furnished, Contractor-Installed (OFCI) protocol, but never touches the procurement decision.
What are the biggest red flags when hiring a contractor in Costa Rica? +
Major red flags include: no CFIA-registered professional on staff, requesting more than 20% upfront before mobilization, a bid significantly below all other quotes, resistance to a detailed written contract, no verifiable reference projects at your project scale, no formal project schedule, and an unclear subcontractor management plan. In Costa Rica's construction market, the cheapest quote almost always reflects missing scope, poor quality materials, or a contractor who will renegotiate mid-project.
Is a verbal agreement valid for construction in Costa Rica? +
Verbal agreements are legally valid under Costa Rican law but extremely difficult to enforce. For any construction project — regardless of size — a formal written contract in Spanish (or bilingual), signed by both parties, is essential. It should define: complete scope of work, technical specifications, milestone payment schedule, change order procedures, delay penalties, warranty terms, and dispute resolution process. Having the contract reviewed by a Costa Rican construction attorney before signing is strongly recommended.
How does direct procurement of specialty items work in practice? +
Direct procurement means the client (or their project manager) selects, purchases, and coordinates delivery of specific high-value items, which the contractor then installs. These items are listed in the contract as Owner-Furnished, Contractor-Installed (OFCI) with reduced contract value for those line items. The contractor remains responsible for correct installation to manufacturer specifications. A qualified project manager coordinates delivery schedules to align with construction progress — avoiding both premature delivery and delays caused by late arrival.
Can a foreign national sign a construction contract in Costa Rica? +
Yes. Foreign nationals can sign construction contracts directly in Costa Rica, whether as individuals or as shareholders of a Costa Rican Sociedad Anónima (S.A.). Most real estate in Costa Rica is held in an S.A., and construction contracts are typically signed by the corporation's legal representative. Having a local attorney review the contract, manage the corporate structure, and serve as legal representative for permit submissions is standard practice for foreign investors.
