(ii) Electrical circuits added to the addition that come from the electrical panel in the manufactured/mobile home.

(iii) Using the manufactured/mobile home for support of the addition.

(b) A plan review is required when adding an addition to a manufactured/mobile home for:

(i) Openings not constructed per the department.

(ii) Manufactured/mobile homes which use the structure for support of the addition.

(iii) Adding a dormer on the home.


Note: An engineer or architect licensed in Washington state must design the plans and seal the plans and calculations. The department's FAS plan review section will perform a plan review.

(c) Labor and industries electrical section is responsible for any electrical circuits added to the manufactured/mobile home that come from the pedestal where the electrical section has electrical inspection authority. Some cities have electrical inspection authority and would make those electrical inspections in their jurisdiction.

(d) Local jurisdiction (city or county) is responsible for the inspection of the addition except as noted above.

(e) Items to pay particular attention to:

(i) If the addition is being served by a required egress door:

The lock must be removed and nonlocking passage hardware installed or the door may be removed entirely leaving a passageway.

An exit door equal in size to the one removed must be installed in the addition.

(ii) If the addition is being served by a 3rd door and the other doors meet the egress requirements outlined above, no changes to the exterior door are required.

(iii) Electrical circuits run from the manufactured/mobile home electrical panel must:

Be in conduit if routed under the home; and

Terminate at the edge of the home in a junction box.

(iv) The addition may be flashed to the manufactured/mobile home for purposes of sealing the exterior joint and may have trim installed on the interior for finishing.

(5) Attaching awnings and carports and garages.

(a) Self-supporting awnings and carports.

When awnings and carports are self-supporting they may be flashed to the manufactured/mobile home and no permit is required from L&I FAS section. Please check with your local jurisdiction building department for any permits required by them.

(b) Awnings and carports using the home for support.

Aluminum or wood awnings and carports that use the manufactured/mobile home for support will need to:

Have the connections to the home designed and the additional load on the home analyzed by an engineer or architect licensed in Washington state. The engineer or architect will need to seal these designs and calculations;

The installer must submit the designs to the FAS plan review section for a review; and

The installer must have the installation inspected, after the plans are approved.

(c) Manufactured home comes from factory garage ready.

If the manufactured home comes from the factory garage ready, no inspection is required by L&I. Garage ready from the factory means:

Dormers, if required, are installed by the factory;

All gypsum board required on the home has been installed at the factory;

Any door between the home and the garage meets the requirements for separation of a residence from a garage as required by the building code;

All electrical installations meet the requirements of the National Electrical Code for one hour walls;

The dryer outlet termination has been designed at the factory to not exhaust into the garage; and

No other changes are required to the manufactured home at the installation site.


Note: If any changes are required to the manufactured home at the installation site, an alteration permit is required from the department.

(d) Manufactured/mobile home is not garage ready.

If the manufactured/mobile home is not garage ready when it leaves the factory, an alteration permit is required. Engineering analysis and plan review may also be required if additional loads are placed upon the home or openings are made or changed.

The following are some examples of when a plan review would be required:

A dormer is added;

An opening in the home is made or changed (Note: Openings constructed to the department's approved details would not require a plan review); and

Gypsum board is added to the wall of the home.

Items to also be aware of:

When a garage is to be attached to a manufactured/mobile home, the following must also be considered:

The means of egress through exterior doors is not compromised (two are required);

The means of egress from the bedroom(s) is not compromised (one egress directly to the exterior from each); and/or endwalls are usually shearwalls and any additional openings in them will need an engineering analysis and plan review to substantiate.

(6) Decertification of a manufactured/mobile home.

(a) Can only be decertified if the jurisdiction having authority will allow the unit to remain on the property.

(b) All electrical components, including the electrical panel, receptacles, switches and light must be removed and wires cut to where they enter the device.

(c) All plumbing fixtures and exposed plumbing water, drain and waste lines must be cut off where they enter any wall, floor or ceiling.

(d) All mechanical components including water heaters, furnaces, and kitchen appliances must be removed from the home.

AMENDATORY SECTION(Amending WSR 99-13-010, filed 6/4/99, effective 7/5/99)

WAC 296-150M-0600   Who establishes standards for installation of manufactured homes?   (1) The director of labor and industries is responsible for establishing uniform installation standards where possible and practical for persons or entities engaged in performing the installation of manufactured homes within the state.

(2) Local jurisdictions may adopt additional installation requirements only for those installation situations not covered by federal standards. For example, local jurisdictions may impose noise control construction ordinances, prescribe the frost depth and soil bearing capacity at the installation site, and adopt requirements to protect manufactured homes in hazardous areas, (see WAC 296-150M-0620).

Also, local jurisdictions may impose their requirements for snow ((and wind)) loads as long as all structures within their jurisdiction are required to comply with the same standard and provided those installing the manufactured home are given options in satisfying that standard. Such an option might include, but not be limited to, allowing an installer to erect an additional structure, which meets local standards, and protects the manufactured home. For example, an installer could erect a free standing ramada over a manufactured home to protect it from local snow loads.

Local jurisdictions may not:

(a) Dictate foundation design and construction which is built according to either the manufacturer's installation instructions or a design created by an engineer or architect licensed in Washington state.

(b) Impose regulations on smoke detectors because they are regulated by federal standards.
