On a phased project, builders risk on an occupied portion often ends or narrows the day people move in unless the insurer has agreed in writing to keep it going. The occupied area then needs the owner's permanent property policy, and the handoff has to be dated, documented and matched to each phase. Gaps usually appear where nobody owns that handoff: model homes, leasing offices, tenant improvement areas and systems still under test.

## Key Decision Points
- Treat each phase turnover as an insurance event, not just a certificate of occupancy date.
- Get the insurer's written consent to occupancy before anyone moves in, and name the occupied area in it.
- Bind the permanent property policy for each phase before builders risk on that phase stops.
- Model homes, leasing offices and systems in commissioning are where phased programs most often leave gaps.
- Occupancy can also start liability repose clocks in California and Arizona, so date it carefully.

## Why Occupancy Changes the Builders Risk Answer

Builders risk is underwritten for a construction site: limited public access, contractors in control, fire protection that is still being installed and a value that climbs as the work goes in. Occupancy changes each of those facts. Residents cook, tenants store inventory, the public walks through a leasing office and the owner's own staff start running equipment. The insurer priced none of that, so most forms contain an occupancy condition that limits, suspends or ends coverage on the portion that is put to use.

The standard owner-contractor insurance exhibit makes the point plainly. AIA A101-2017 Exhibit A says owner occupancy or use of any completed or partially completed portion before substantial completion shall not begin until the builders risk insurer consents in writing to continued coverage. It also says the owner and contractor should take no action on partial occupancy that would cancel, lapse or reduce the insurance unless they agree otherwise in writing. Many manuscript and market forms reach a similar result through their own wording, so read the actual policy rather than assuming the exhibit controls.

The practical result is that turnover dates belong on the insurance calendar. A phase that opens on a Friday with no consent on file may be a phase with no property insurance over the weekend.

## Occupancy Clauses and Permission to Occupy

Occupancy wording varies more than most buyers expect. Some forms end coverage on any portion once it is occupied or put to its intended use. Others end it only when the owner accepts the work, or when a stated percentage of the building is occupied. A few allow partial occupancy for a set number of days without notice. The trigger words matter: occupied, put to use, accepted, completed and taken over are not interchangeable, and a loss adjuster will read the one in your policy.

Permission to occupy is usually granted by endorsement. A useful endorsement names the occupied area by building, floor, unit range or suite; states whether builders risk continues on that area or ends on a stated date; confirms that coverage on the rest of the work continues unchanged; and addresses any new protective conditions, such as fire separation or a monitored alarm. Ask for it early, because underwriters often want the phasing plan, the life-safety sign-off and a description of the occupant's use before they agree.

The contract side matters too. The owner-contractor agreement should say who requests the consent, who pays any added premium and what happens to the contractor's care, custody and control obligations for the occupied area.

- Trigger words to find in the form: occupied, put to use, accepted, completed, taken over
- Endorsement items: named area, coverage status, effective date, protective conditions
- Contract items: who asks for consent, who pays, who controls the occupied area

Pad turnovers and tenant fit-outs raise the same questions; see [insurance for phased commercial and tenant improvement projects](https://mycontractorsinsurancequote.com/projects/commercial-construction).

### Illustrative scenario: Arizona Garden-Style Community Leasing by Building

A developer is building a 14-building garden-style community outside Phoenix and plans to lease the clubhouse and the first two buildings while the remaining 12 are framed and roofed. The builders risk form in force ends coverage on any building once it is occupied, so the broker asks the insurer for a permission to occupy endorsement naming the clubhouse and buildings 1 and 2, and binds the owner's permanent property policy on those three structures effective the same morning. Because A.R.S. §12-552 can treat first use by an occupant as substantial completion, the developer's counsel also logs each building's move-in date for the liability file. When a dryer fire in building 2 later damages framing in building 3 next door, the adjuster can see which policy carries which building.

## When Builders Risk Ends and the Permanent Property Policy Begins

Builders risk does not usually hand off to anything automatically. The owner's permanent property policy, sometimes called the operational or completed-building policy, has to be bound for each phase with its own values, deductibles and insured locations. If builders risk ends at occupancy and the permanent policy starts at the certificate of occupancy, a loss in between may fall to neither. Line the two dates up on paper, phase by phase, before the first turnover.

Value is the second issue. The builders risk limit was set at the completed value of the whole project, while the permanent policy for phase one should carry the replacement cost of what is finished and occupied. As later phases turn over, the permanent schedule grows and the builders risk exposure shrinks. Ask the builders risk insurer whether the limit and premium adjust, or whether the policy simply continues on the unfinished portions at the original value.

Lenders watch this closely. Loan documents commonly require continuous property insurance with the lender as mortgagee, and a permanent lender may want its own endorsement in place before funding. A gap between the two programs can be a loan default even if no loss occurs.

Mortgagee clauses and continuity conditions are summarized in [what construction and permanent lenders require](https://mycontractorsinsurancequote.com/resources/lender-insurance-requirements).

## Model Homes, Sales Centers and Leasing Offices

For-sale residential projects create an early, small occupancy that is easy to miss. A builder finishes three models and a sales center, furnishes them, staffs them and opens them to the public while the rest of the phase is still framed. Builders risk forms often exclude or limit coverage for model homes once they are open, and furnishings, signage and sales equipment are rarely within builders risk at all. The builder's own property policy may not list the models as locations either.

Ask how the program treats each model: whether builders risk continues while it is used for sales, what happens to furnishings and whether the builder's property policy picks up the structure on a stated date. The same question applies when a model is later sold and closed. Liability changes too, because the public is now on site, so confirm that the general liability program contemplates sales traffic and open houses.

Multifamily lease-up raises a similar issue. The leasing office and clubhouse often open before the residential buildings, and amenity spaces fill with furniture, fitness equipment and technology that belong on the owner's property schedule, not on builders risk.

Subdivision and multifamily programs are covered in more depth under [for-sale and multifamily residential project insurance](https://mycontractorsinsurancequote.com/projects/residential-construction).

## Multifamily Lease-Up: Residents Beside Active Construction

Garden-style and podium multifamily projects commonly lease buildings or floors as they receive certificates of occupancy. That means residents living next to active framing, drywall and roofing, with hot work and temporary power nearby. The occupied buildings typically move to the owner's permanent property policy, while the unfinished buildings stay on builders risk. The boundary between the two has to be clear enough that an adjuster can tell which policy responds to a fire that starts in one and spreads to the other.

Underwriters on both sides will ask about separation: fire barriers, sprinkler zones in service, site access controls and whether residents share parking or utility rooms with the construction area. Federal construction safety rules also matter here. OSHA's construction fire protection standard calls for a fire protection program through all phases of construction, and phased occupancy makes that program more demanding, not less.

Water is the other recurring loss. A supply line failure in an unfinished unit above an occupied one can damage both, so confirm how each policy's water damage deductible applies and whether the two insurers have agreed on how to share a loss that crosses the boundary.

## Testing and Commissioning on a Partly Occupied Site

Phased projects rarely finish their building systems in one sequence. The central plant, fire pump or main switchgear may serve an occupied phase while still being tested for later phases. The AIA exhibit calls for builders risk to include building systems damaged in testing and startup, but many market forms limit testing to a set period, end coverage on a system once it is accepted or exclude damage while a system carries an operational load. A system serving residents or tenants is carrying an operational load.

Ask the builders risk insurer how it treats a shared system: whether it remains insured during testing for the unfinished phases even though it already serves the occupied one, and which policy responds if it fails. Ask the permanent property insurer the same question, since equipment breakdown coverage on the operational policy may exclude systems that are still under construction warranty or commissioning. Write the answers down and tie them to the commissioning schedule, which often slips past the dates the quotes assumed.

Data halls and plants that energize in phases face the hardest version of this question; see [testing and phased energization on equipment-heavy projects](https://mycontractorsinsurancequote.com/builders-risk-insurance/industrial-and-data-center-projects).

## Occupancy Can Start Liability Clocks Too

Phased occupancy is not only a property question. In California, Code of Civil Procedure §337.15 bars most latent deficiency actions more than 10 years after substantial completion, and it starts that clock no later than the first of several events, one of which is the date of use or occupation of the improvement. Arizona's A.R.S. §12-552 treats an improvement as substantially complete when it is first used by the owner or occupant, if that comes before the other listed events, for its eight-year limit on contract-based actions.

For a phased project, that can mean the completed operations exposure on phase one starts years before the last phase closes. Developers and GCs should record the occupancy date for each phase, keep it with the project file and give it to the broker so the liability program's completed operations term and any project-specific extension are measured from the right dates. How these statutes apply to a particular project is a question for counsel.

## Before You Ask for a Quote

### What to Gather
- The phasing plan with planned occupancy dates by building, floor or unit range
- The builders risk policy's occupancy condition and any existing permission to occupy endorsement
- Permanent property quotes or binders for each phase, with effective dates
- The commissioning schedule showing shared systems that serve occupied and unfinished areas
- Loan document insurance sections from the construction and permanent lenders
- A list of model homes, sales centers, leasing offices and amenity spaces with planned opening dates

### What to Ask the Insurer or Surety
- Which words in the form end coverage on an occupied area, and does notice alone keep it in force?
- Will the insurer issue written consent naming each occupied area before move-in?
- Does the builders risk limit or premium adjust as phases move to the permanent policy?
- How are shared building systems treated while they serve occupied areas and are still under test?
- Which policy responds to a loss that starts in an occupied phase and spreads to an unfinished one?
- Are model home furnishings and sales equipment insured anywhere?

## Broker Notes

**Quick Answer:** Builders risk on an occupied portion of a phased project often ends or narrows at occupancy unless the insurer consents in writing, so each phase needs both a documented consent and a permanent property policy bound before move-in.

**Common Mistake:** Using the certificate of occupancy date as the only handoff date. If builders risk ends at first use and the permanent policy starts later, a fire in between may fall to neither policy.

**Broker Perspective:** A broker builds a turnover calendar that lists every phase, its occupancy date, the consent endorsement and the permanent policy effective date, and checks it against the commissioning schedule.

**Coverage Impact:** Coverage on occupied areas typically depends on the occupancy condition and any endorsement in the actual policy; shared systems and model homes are the areas most likely to fall between programs.

## Questions Buyers Ask

### Do we need the builders risk insurer's approval before the first tenants move in?

Usually, yes. Many builders risk forms limit or end coverage on a portion that is occupied or put to use, and the AIA owner-contractor exhibit says owner occupancy before substantial completion should not begin until the insurer consents in writing. Ask for a permission to occupy endorsement that names the area and states whether builders risk continues on it, and get it before move-in rather than after.

### Can builders risk and the owner's permanent property policy both apply to the same finished floor?

It can happen during a transition, and overlapping coverage is far easier to resolve than a gap. Some programs deliberately overlap by a few days around each turnover. Others end builders risk on a date and start the permanent policy on that date. Either can work if both insurers know the plan, the effective dates match and each policy's other-insurance clause has been read.

### Are furnished model homes still under builders risk once they open for sales?

Often only partly, and sometimes not at all. Many builders risk forms treat an open model as occupied, and furnishings, signage and sales equipment are rarely within builders risk. Ask the builders risk insurer how it treats each model and confirm that the builder's own property policy lists the models and their contents from the opening date.

### Who should request the occupancy consent on a GC-purchased builders risk policy?

The named insured on the policy makes the request, which on a GC-purchased program is the contractor, but the owner's decision to occupy usually drives it. The owner-contractor agreement should say who asks, who pays any added premium and how much notice the owner gives before move-in, so the GC is not learning about occupancy from a moving truck.

### Does early occupancy of one building change our defect claim exposure on that building?

It may. California's §337.15 starts its 10-year latent deficiency clock no later than the date of use or occupation (among other events). Arizona's §12-552 can treat first use by an occupant as substantial completion. Record each phase's occupancy date and ask counsel how the statute applies, then measure completed operations protection from those dates.
