The strap must be identified -MINUTE MAN ANCHORS INC. CERTIFIED ANSI
225.1 AND ASTM D3953."
2. WHEN EXTENDING OR SPLICING IWO STRAPS, OVER IAP APPROX. 6-, USE IWO
SEALS FULLY CRIMPING EACH SEAL TWICE TO BOTH STRAPS.
3. WHEN STRAPPING TO AN APPLIANCE SUCH AS SLOT IN A VERIICLE TIE OR A
HOOK OR A BUCKLE WE SUGGEST THAT YOU USE A SHORT PIECE OF STRAP
(RADIUS CUP) BEM 180 degrees IN DIRECT CONTACT WITH THE APPLIANCE.
(This wit act as o cushion, reinforce and prevent sharp bends in the strap.)
NEXT INSERT THE STRAP BENDING R OVER 180 degrees BACK TO THE STRAP.
USING ONE SEAL PLACE BOTH STRAPS INTO SEAL AND CRIMP TWICE.
4. SEALS MUST ALWAYS BE CRIMPED TWICE.

E -Z ANCHOR INSTALLATION METHOD
Note: WiM machine installation. a Minute -Man adapter designed to fit both the anchor head and drive 'machine
shaft is available. Installers do not need additional or special equipment for E -Z Anchor Installation
E -Z Anchors are a patented ,tem.
1. MACHINE INSTALLATION
The drive machine is started and the anchor
is tumed into the ground to a point where the
top (stabilizer head plate) is flush with or
slightly below ground level. This assures that
the E -Z Anchor Stabilizer will be at its
required installation position. See Figure A.
To achieve full potential, install the E -Z
Anchor vertically. A 10° deviation from
vertical is acceptable. See Figure A.
Note: A slightly greater angle may be used to start
anchor to avoid contact with the home and
straightened as anchor is ground set. The splitbolt is
inserted, strap is fastened, and tightening adjustment
made.
E -Z Anchor carries U.S. Patents and
manufacture Is exclusive to Minute -Man
Anchors, Inc.
2. STANDARDS FOR INSTALLATION
• E -Z Anchors and all components are to
be installed per manufacturer's
instructions.
• E -Z Anchors are approved for designated
Soil Class III, IV.
• E -Z Anchor working load capacity is
3,150 pounds for a single tie or the load
of (2) ties combined.. See Figure B.
• Consult manufactured home set up
instructions for number of frame tie
downs, over the roof tie downs and tie
down spacing.
• Proper site preparation requires removal
of grass and sod prior to installation.
For additional information, copies of engineering test(s) and report.

INSTALLATION NU -CONCEPT ANCHOR
Potent Fendhg
CLASS 3&4
The) lu-Concept Anchor combines a patented elongated hole in the tension head with
a stabilizing and compaction cap. When combined with a grade 5 bolt, the anchor Will
rotate in all directions allowing adjustment to uneven terrain. Under loud conditions the
cap, rotates down ward In the direction of the put, causing a double compaction of the
sot and laterally restricts movement of anchor through the sot.
I , Attach stabtzer/ compaction cap to the tension head of the anchor. This is done by gang
the cap over the top of the tension head, aligning 9/3T holes in cop with 1/4" elongated
hole in tension head. Insert 1/4" x 2-1/4", grade 5 bolt (Included). Hand tighten. Cap must
beinstalled atanytime prior toground contact. Figure A

III. Anchor is pre -loaded. Pre -load causes
the cap to rotate downward in the
direction of put, further compacting the
sot and presenting a larger surface
area, resisting both horizontal and
vertical movement. See Figure D
When used with rigid support tubes,
rather than strap systems, pre -loading is
not required.
Note: A special adapter Is awiloble to insure against tension head and bolt damage

E -Z ANCHOR INSTALLATION METHOD
Note: With machine installation. a Minute -Man adapter designed 10 01 both the anchor head end drive machine
shaft is available. Installers 40 001 need additional or special equipment for E -Z Anchor InstallabOn.
E -Z Anchors are a patented Item.
1. MACHINE INSTALLATION
The drive machine is started and the anchor
is turned into the ground to a point where the
top (stabilizer head plate) is flush with or
slightly below ground level. This assures that
the E -Z Anchor Stabilizer will be at its
required installation position. See Figure A.
To achieve full potential, install the E -Z
Anchor vertically. A 10° deviation from
vertical is acceptable. See Figure A.
Note: A sfightly greater angle may be used 10 0(04/
anchor to avoid contact with the home and
straightened as anchor is ground set. The sphlbolt Is
inserted, 01009 13 fastened, and tightening adjustment
made.
E -Z Anchor carries U.S. Patents and
manufacture Is exclusive to Minute -Man
Anchors, Inc.
2. STANDARDS FOR INSTALLATION
• E -Z Anchors and all components are to
be installed per manufacturer's
instructions.
• E -Z Anchors are approved for designated
Soil Class III, IV.
• E -Z Anchor working load capacity is
3,150 pounds for a single tie or the load
of (2) ties combined.. See Figure B.
• Consult manufactured home set up
instructions for number of frame tie
downs, over the roof he downs and tie
down spacing. ;
• Proper site preparation requires removal
of grass and sod prior to installation.

American National Standard
Approval of an American National Standard requires verification by ANSI that the requirements for
due process, consensus, and other criteria for approval have been met by the standards developer.
Consensus is established when, in the judgmentof the ANSI Board of Standards Review,
substantiae agreement has been reached by directly and materially affected interests. Substantial
agreement means much more than a simple majority, but not necessarily unanimity. Consensus
requires that all views and objections be considered and that a concerted effort be made toward their
resolution.
The use of American National Standards is completely voluntary; the existence of the standard
does not in any respect preclude anyone, whether he/she has approved the standards or not, from
manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming
to the standards.
The American National Standards Institute does not develop standards and will in no circumstances
give an interpretation of any American National Stand.rd. Moreover, no person shall have the right
or authority to issue an interpretation of an American National Standard in the name of the American
National Standards Institute. Requests for interpretations should be addressed to the secretariat or
sponsor whose name appears on the title page of this standard.
CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The
procedures of the American National Standards Institute require that action be taken periodically to

1.2.1 Types of manufactured homes covered
The manufactured homes covered under this
standard are manufactured homes complying
with the U.S. Department of Housing and Urban
Development (HUD)'s MHCSS Program, as set
forth in 24 C.F.R., Parts 3280, 3282, and 3283,
as mandated in the United States of America
and manufactured homes built prior to June .15,
1976, including those complying with the
Standard for Mobile Homes, NFPA 5018/ANSI
A119.1 edition, in effect at the time of
manufacture.
NOTE — The Federal standards, regulations, and
requirements for manufactured housing, as
authorized by 42.U.S.C.5401 et seq., are as follows:
'Part 3280 — MHCSS
'Part 3282 — Manufactured Home Procedural and
Enforcement Regulations
'Part 3283 — Manufactured Home Consumer
Manual Requirements
Hereafter, throughout sections threethrough
eight of this document, 'manufactured home`
will be .used interchangeably with 'home."
1.2.2 Applicability
This standard is designed to be adopted by
authorities having jurisdiction over and
responsible for the safety and health of
manufactured home users. It is intended to
apply to all home installations, whether at new
or existing manufactured home sites.
While this standard provides useful technical
data for improvements to existing sites falling
within its scope, and such use is encouraged, it
is not intended to be applied retroactively to
existing sites exceptwhere the authority having
jurisdiction considers such application essential
for the safety and health of the occupants or
users of the sites. This standard shall not be
construed as relieving the installer of a
manufactured home of the responsibility for
compliance with the codes and regulations .
established by the authorities having jurisdiction.
1.2.3 Organization of standard
This standard consists of eight sections,
generally divided by the kinds of work involved in
property setting up a home.
1.2.4 Use of this standard
This standard contains instructions, including
specifications and procedures, for installation
1
NCSBCS/ANSI A225.1
and hook-up of a manufactured home. It has
been written in an objective and
easy -to -understand manner so that it can be
understood by those who lack extensive
technical training. It discusses the installation of
the home from preparation of the site through
final inspection. It includes many tables and
figures giving important data for proper
installation.
Careful adherence to this standard by the home
owner and installation crew, and consultation
with a registered engineer in those unusual
circumstances it does not cover, will help ensure
the home owner of a well-built, safe, and
affordable home for many years to come.
1.3 Preinstallation considerations
Prior to locating or relocating a manufactured
home, the authority having jurisdiction shall be
contacted for installation procedures.
Some jurisdictions require licensed or registered
installers. Many jurisdictions require permits to
be obtained prior to the installation of such
items as blocking, anchoring, and electrical and
sewer or water connections or both. Inspections
will be required in conjunction with permits to
help ensure a correct and safe installation of the
manufactured home, with notification to the
jurisdiction at different, times during the
installation.
For private property, installation zoning or
development covenants may apply and should
also be taken into consideration.

3 Site preparation
3.1 .Location and layout
3.1.1 Use of zone maps
A home is designed for certain weather
conditions and roof loads [see zone maps near
main electrical panel and in figures 3-1(a), (b),
and (c)J. Do not site or relocate a home in a
zone requiring greater wind, roof load, or
heating or cooling capabilities than those for
which it was designed.
3.1.2 Access for transporter
Before attempting to move a home, ensure that
the transportation equipment and home can be
routed to the installation site. Special
transportation permits may be required from
state, county, or city officials.
3.1.3 Encroachments and setback distances
Local laws regarding
yards, and courts
permissible setback
lines and public roads
encroachments in streets,
shall be obeyed, and
distances from property
shall be met.
3.1.4 Fire separation distance
The distance a home must be sited from other
structures depends on its fire resistancee rating
and on local requirements. Contact the home's
Manufacturer or the inspection agency identified
on the data plate for fire -resistance rating
NCSBCS/ANSI A225.1
information.
3.1.5 Issuance of permits
Ensure that all necessary local permits have
been obtained and fees paid.
3.2 Soil conditions
3.2.1 Requirements
To help prevent sewing or sagging, site the
home on firms undisturbed soil or fill compacted
to at feast 90 percent of its maximum relative
density. Installation on loose, uncompacted fill
may invalidate the home's limited warranty.
3.2.2 Bearing capacity
Test the bearing . capacity of the soil in
accordance with 3.2.3 before. designing the
foundation. If the soil cannot be tested, but its
type can be identified, use the foundation
bearing pressures shown in table 3-1 as a
guide. If you cannot identify the soil, use a
bearing capacity of 1,000 pounds per square
foot. Under unusual conditions, or if the soil
appears to be composed of peat or
uncompacted fill, consult a local geologist,
engineer, or architect.
3.2.3 Soil -bearing testing methods and
equipment
Use a pocket penetrometer or other methods
acceptable to the local jurisdiction having
authority.
3.3 Removal of organic material
Removal of all decayable material, such as
grass, roots, twigs, and wood scraps, from
beneath the home is required in areas where
footings are to be placed, to minimize settling of
footings and insect damage. Remove shrubs
and overhanging branches from the immediate
vicinity of the home site to prevent windstorm
damage.

6
NCSBCSIANSI A225.1
3.4 Drainage
3.4.1 Purpose
Proper drainage prevents water build-up under
the home, which may cause shifting or settling
of the foundation, dampness in the home,
damage to siding and bottom board, buckling of
walls and floors, and problems with the
operation of doors and windows.
3.4.2 Elimination of depressions
Grade the home site to permit water to drain
from under the home (see figure 3-2).
3.4.3 Drainage structures
Depending on the local landscape, ditches and
culverts may be needed to drain surface runoff.
if so, consult a registered engineer.
3.4.4 Gutters and downspouts
When gutters and downspouts are installed,
direct
the run off away from the home.
3.5 Ground moisture control
3.5.1 Vapor retarder
If the space under the home is to be enclosed
with skirting or other material, a vapor retarder
that keeps ground moisture out of the home
shall be installed .
3.5.2 Acceptable types of ground cover
Use a minimum of six -mil polyethylene sheeting
or its equivalent.
3.5.3 Proper installation
Cover the entire area under the home with the
sheeting and overlap it at least 12 inches at all
joints. Where soil and frost conditions permit
placementof footings at grade level, place the
sheeting directly beneath the footings.
4 Foundations
NOTE — This section only covers foundations.
Installation procedures and methods for securing
the home to its foundations are discussed in 5.
•
4.1 Piers
4.1.1 importance
Proper pier installation is the most important part
of home installation. incorrect size, location, or
spacing of piers may cause serious structural
damage to the. home. It is important to install
piers around the perimeter as required. Failure
to do so may lead to sagging floors, walls, and
roofs (see 4.1.5.3).
4.1.2 Acceptable types
Piers may be concrete blocks, pressure -treated
wood having 0.60 retention in accordance with
American Wood Preservers Association (AWPA)
C22 Standard, or adjustable metal or concrete
piers (see figure 4-1). Manufactured piers shall
be listed or labeled for the required Toad
capacity.
4.1.3 Design requirements
4.1.3.1 Load-bearing capacity
The load that each pier must carry depends on
such factors as the dimensions of the home, the
roof live load, the spacing of the piers, and the
way the piers are used to support the home.
Center beam/marriage wall blocking is required
for multisection homes.
See tables 4-1 and 4-2 for pier capacities.
These tables shall be used when the
manufacturer's installation instructions are not
available. Manufactured piers must be rated at
least to these capacities, and locally constructed
piers must be designed to transmit these loads
safely (see 4.1.3.2).
4.1.3.2 Configuration
Figure 4-1 shows the recommended
arrangement of concrete block piers constructed
on site. Load-bearing (not decorative) concrete
blocks should have dimensions of at least 8
inches x 8 inches x 16 inches. They must be
stacked with their hollow cells atigned vertically.
When piers are constructed of blocks stacked
sloe oy side, each layer should be at right
angles to the previous one (see figure 4-1).
Cap hollow block piers as shown in figure 4-1 to
distribute the structural load evenly across them.
Caps may be of solid masonry of at least 4
inches nominal thickness or hardwood at least 2
inches nominal thickness, or of steel (see figure
4-1). All caps shall be of the same length and
width as the piers upon which they rest. Avoid
Using plywood, as it may lead to unwanted
settling.
Use 4 -inch x 6 -inch hardwood shims to level the
home and fill any gaps between the base of the
I-beam and the top of the pier cap. Always use
shims in pairs (see figure 4-1). Drive them in
tightly so that they do not occupy more than 1
inch of vertical space. Use hardwood plates no
thicker than 2 inches to fill in any remaining
vertical gaps.
Select manufactured pier heights so that th
adjustable risers do not extend more than 3
inches when finally positioned.
All piers must rest on footings (see 4.2) that
extend below the frost line (see 4.2.2 for
exceptions to placement) and are placed on
either undisturbed soil or compacted fill.
should be listed and labeled. •
4.1.4.2 Piers 36 inches to 80 incheshigh and
corner piers
Construct all piers between 36 inches and 80
inches high and all corner piers • over three
blocks high out of double, interlocked concrete
blocks (see figure 4-1): Mortar will not normally
be required. •
4.1.4.3 Piers over 80 inches high
Where permitted by local codes, lay blocks in
concrete mortar with steel reinforcing bars
inserted in the block cells and fill the cells with
concrete. Where such construction is not
permitted by local codes, piers over 80 inches
high shall be designed by a registered engineer.
4.1.4.4 Elevated homes
e When more than one-fourth of the area of a
home is installed so that the bottom of the
main-frame members are more than 3 feet
above ground level, the home stabilizing
devices shall be designed by a qualified
engineer and be approved prior to installation by
the. authority having jurisdiction.
4.1.5 Location and spacing
The location and spacing of piers depend upon
the dimensions and weight of the home, the
roof load zone, the type of construction (single -
or multisection), and such other factors as the
location of doors or other openings. In general,
locate piers no more than 2 feet from either end
and not more than 8 feet center -to -center under
the main rails.
4.1.3.3 Clearance under homes
A minimum clearance of 12 inches shall be
maintained beneath the lowest member of the
main frame (I-beam or channel beam) in the
area of utility connections. No more than 25
percent of the lowest member of the main frame
of the home shall be less than 12 inches above
grade.
4.1.4 Design procedures
4.1.4.1 Piers less than 36inches high
• Piers less than 36 inches high may be
• constructed of single, open, or closed -cell
concrete blocks, 8 inches x 8 inches x 16
inches. Install them so that the long sides are
at right angles to the supported I-beam (see
figure 4-1). Position open cells at right angles to
the footers. Horizontal offsets should not
exceed 1/2. inch top to bottom. Mortar will not
normally be required. Manufactured piers
4.1.5.1 Single -section homes
Figure 4-2 shows the recommended location
.and spacing of piers for a single -section home
when the manufacturer's installation instructions
are not available.
4.1.5.2 Multisection homes

are not available.
4.1.5.3 Perimeter blocking
Place piers on both sides of side wall exterior
doors and any other side wall openings greater
than 4 feet (such as entry and sliding glass
doors); under porch posts, fireplaces, and wood
stoves; and under the locations where heavy
pieces of furniture, such as pianos, organs,
waterbeds, etc., are expected to be placed.
4.2 Footings
Footings shall be placed a minimum of 4 inches
below grade in undisturbed soil. Support every
pier with a properly designed footing (see
4.2.1.1).
4.2.1 Acceptable types of footings
4.2.1.1 Concrete
Footings may consist of precast or
poured -in-place concrete, pads, slabs, or
ribbons at least 3 1/2 -inches thick, with a 28 -day
compressive strength of at least 3,000 pounds
per square inch.
4.2.1.2 Pressure -treated permanent wood
Two layers of nominal 2 -inch thick
pressure -treated wood having 0.60 retention in
accordance with AWPA C22 Standard, with the
long dimensions of the second layer placed
perpendicular to that. of the first, may also be
used.
4.2.1.3 Other materials
•
• Other. materials approved for footings may be
used when approved by local authorities if they
provide equal load-bearing capacity and
resistance to decay. Examples include;
— 1/2 inch maximum crushed stone;
— 3/8 inch or 3/4 inch graduated gravel;
— coarse sand, with grains no smaller than
1/16 inch, placed so it provides a soil -bearing
capacity of at least 3,000 pounds per square
foot.
4.2.2 Placement in freezing climates
4.2.2.1 Conventional footings
In areas subject to ground frost heave, place
footings below the frost line. Consult local
authorities 10 determine the depth of the frost
Zine. In the absence of a local code, use the
frost penetration map provided in figure 4-4 as
a guide.
4.2.2.2 Floating stab systems
When properly designed by a registered
professional engineer, a 'floating slab system'
may be used above the frost line. The design
shall accommodate the anchorage
requirements identified in 5.
4.2.2.3 Insulated foundations
Footings may also be placed above the frost
line when the home is provided with a perimeter
foundation or skirting having insulation
properties sufficient to prevent freezing of the
soil under or adjacent to every load-bearing
component of the foundation and acceptable
for this purpose to the authority having
jurisdiction. Useful design guidelines may be
found inthe references found in Annex F.
Insulation systems should be compatible with
the requirement to cross -ventilate the entire
space under the home.
4.2.3 Proper sizing of footings
Proper sizing of footings depends upon the
• load -carrying capacity of both the piers and the
soil. See table 4-3 for recommended footing
sizes.
4.3 Permanent foundations
Check local building codes and regulations and
consult a registered engineer when the home is
to be sited on a permanent foundation (such as
a full basement, crawl space, or load-bearing
perimeter foundation). To obtain a permanent
foundation design that meets most local Codes,
write to the manufacturer of the home. Useful
ideas and design guidelines can also be found
in reference publications, such as those listed in
Annex F.
4.4 Special considerations
Also see 5.5.3.
4.4.1 Areas prone to flooding
Special elevations and anchoring techniques
are required when locating a home in an area
prone to flooding. Consult an engineer and the
local building official to make sure that home
design and construction conform to applicable
federal, state, and local codes and regulations.
The Federal Emergency Management Agency
(FEMA) publication listed in Annex F'contains
design and construction recommendations for
elevated foundations as well as for connections
and anchoring systems that will allow the
foundation system to resist flood forces.
4.4.2 Severe wind areas
Special foundation and anchoring techniques
are required when locating a home in a severe
wind area is unavoidable. Consult a registered
engineer. The HUD foundations design guide
listed in Annex. F contains recommendations for
designing foundations and anchoring systems.
Do not place the home in a more severe wind
zone than the one indicated on the data plate
posted in the home.
4.4.3 Special snow load conditions
Hcmes designed for and located in heavy
snowfall areas or that are subjected to other
extreme loading conditions may require special
piers or footings. Check with the local authority
having jurisdiction.
4.5 Important reference documents
See Annex F.

suspend/support them above the ground (see
figure 5-1).
10
5.5 Anchoring instructions
After blocking and leveling, the installer should
secure the manufactured home against the
wind, unless the jurisdiction permits otherwise.
The type of installation is the determining factor
in deciding how this should be done, as is
described in the following sections.
5.5.1 Normal installations
Table 5-1 summarizes and defines the types of
normal installations. The pier -and -ground -
anchor system, as provided in this standard, is
most common. When using another type of
installation, consult a registered engineer.
NOTE - The anchoring or foundation system shall
be capable of meeting the loads required by the
MHCSS.
5.5.1.1 Number and location of anchors
Select the number and location of straps and
anchors from the chart and diagram in figure
5-2. Use either the single- or the double -strap
method. Use only approved ground anchors
capable of resisting at least the minimum loads
given in the chart for the method selected.
5.5.1.2 Installation of anchors
The following is one example: Install the
anchors at the locations selected from figure 5-2
when the home manufacturer's installation
instructions are not available. Follow the anchor
manufacturer's instructions. Use single -headed
anchors at all "frame -tie -only" locations when
using the single -strap method, and
double -headed anchors when employing the
double -strap method. Install single- or
double -headed anchors at all over -the -roof -tie
locations. When using a single strap, line up
the shaft of each anchor with its strap (see
figure 5-3). When connecting more than one
strap to a single anchor, line the shaft of the
anchor with the results achieved by calculating
the combined forces (see figures 5.4). The
ground anchors must be sized for the direction
of the load and the type of soil. (See figures 5.3
and 5.4 for additional information on the
installation of anchors and tiedowns.)

extension request is granted, you will be notified by mail.
In the event you do not call for an inspection and/or receive an extension prior to 10/06/2013, your permit will become null
and void and any further work on the project will require a new permit and associated fees.
Thank you for your cooperation in this matter.

read or am familiar with RCW 18.27.090.
3. I understand that prior to issuance of a permit for work which is to be done by any contractor, the
City of Tukwila must verify either that the contractor is registered by the State of Washington, or that
one of the exemptions stated under RCW 18.27.090 applies.
4. In order to provide verification to the City of Tukwila of my compliance with this requirement, I
hereby attest that after reading the exemptions from the registration requirement of RCW 18.27.090,
I consider the work authorized under this permit to be exempt under numbert , and will therefore
not be performed by a registered contractor.
5. I understand that the licensing provision of RCW 19.28.161 through 19.28.271 shall not apply to
persons making electrical installations on their own property or to regularly employed employees
