PERMANENT RULES
LABOR AND INDUSTRIES
Effective Date of Rule: Thirty-one days after filing.
Purpose: The purpose of this rule making is to amend the manufactured home rules to make sure they are consistent with the statute. The amendment which amends "notice of infraction" to "notice of correction." This will correct the terminology in the rule for consistency between the statute and rules. The factory assembled structure program has already filed an expedited rule-making package to correct terminology in WAC 296-150M-0815.
Additional housekeeping and clarifying changes will be made throughout the rule.

(d) On generic designs that are to be used more than once, an engineer or architect must clearly state in writing on the original stamped drawings that the design plans may be used on other manufactured/mobile homes of the same manufacturer.
(4) Additions (i.e., rooms, garages, carports, etc.) added to manufactured/mobile homes.
(a) Labor and industries factory assembled structures section is responsible for any alterations to the manufactured/mobile home. This includes:
(i) Any opening that is added or changed.
(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. |
(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.

(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. |
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.
