State Adopted Building

Regulations for the Construction

of

Manufactured Buildings — An Analysis

1. Purpose

The purpose of this report is to examine and summarize the current

status of State adopted building regulations (i.e., codes and standards)

that have been promulgated in conjunction with statewide regulatory

programs pertaining to the construction of manufactured building. Specif ically

,

the report presents the results of a preliminary study based on information

supplied by State authorities. The study was conducted to identify and

examine various characteristics of regulatory programs in those States which

promulgate and administer regulations for this type of building construction

on a statewide basis. Those characteristics include the following:

the technical basis (e.g., nationally recognized model codes)

upon which the regulations adopted in each State are based;

the extent to which the established technical provisions

contained in nationally recognized model codes have been

amended by the States for the regulation of manufactured

building construction;

the differences in regulatory treatment of manufactured building

construction and conventional building construction;

the occupancy classifications covered by each State's manufactured

building regulatory program;

1
the type of compliance assurance activities (e.g., evaluation,

approval, production inspection and certification processes); and

legal definitions for "manufactured building" and related terms

(e.g., "factory-built housing," "Industrialized building," etc.)

that are applicable in each State that has statutes governing this

form of construction.

2. Background Information

Significant developments have occurred over the past decade (1966-1976)

in the cause-effect relationship of supply to demand of adequate shelter.

Building codes and standards, increasing labor, land and materials costs,

and changing life styles have all combined to affect the inventories and

types of structures built. The demand for more efficient and/or less

expensive construction than conventional on-site "stick-built" construction

has to a great extent given rise to an increase in the raanuf actured/industrialized

building process. This process extends from complete building "systems" down to

factory-produced building components. As a result, the use of manufactured

buildings has increased significantly over the past ten years. The Federal

Government in 1969 assisted this development through "Operation Breakthrough"

sponsored by the U.S. Department of Housing and Urban Development (HUD).

While the evaluation of the building systems developed as a result of

"Operation Breakthrough" may still be open to discussion. Federal "sanctioning"

of factory methods to solve conventional building construction problems

2
generated a response from the States for regulatory programs and technical

criteria to meet the needs of the proliferating industry. As might be

expected, State regulatory programs for the regulation of manufactured

building construction have not been uniform in their adoption of technical

criteria and their approach to enforcement. [1]*

3. Discussion of Findings

According to the information available, thirty States have

enabling legislation and regulatory programs in effect for the regulation

of manufactured building construction. For several other States, the

enabling legislation is awaiting enactment or the regulatory program itself

is in various stages of development. Specific information on various

characteristics of these programs is presented in a series of three summary

tables (Tables 1, 2, and 3) and is depicted graphically on an outline map

based on State population distribution in Figure 1.

Table 1 provides information on the legislation enacted in each State

and includes the status of certain features of the regulatory program adopted

in response to the statutes. This tabulation also includes information on

the One and Two Family Dwelling Code [21 and the extent of its adoption by

the States as a basis for regulating or accepting manufactured housing units.

^Figures in brackets indicate the literature references listed in Section 5.
The information presented in Table 2 includes the building occupancy

classifications (as promulgated by the Model Codes Standardization Council

(MCSC)) covered by each State's regulatory program. This table also includes

the type of process followed by the States in their respective compliance

assurance programs for the evaluation, approval, production inspection and

certification of manufactured buildings. For purposes of the table, the

term "independent agency" means an accredited inspection agency or "Third

Party" agency recognized by the State. The column heading "State Agency

Monitoring Inspections" is intended to include those State agency functions

in which unannounced random monitoring inspections are conducted to assure

that the independent agency is performing properly.

Table 3 pertains to the codes and standards which have been adopted by

the States as the technical basis of regulating manufactured building construction. Table 3 also indicates if the nationally recognized model codes

have been strictly adopted or have been modified with respect to technical

content by the States. This information is also depicted graphically in

Figure 1. Further information on the status of each State's adopted codes

and standard and the type of modifications that have been made, if any, is

provided in Section 4 and Appendix A of this report.

Many of the States with enabling legislation and administrative rules

and regulations for the construction of manufactured buildings have definitions

for "manufactured building" and related terms. Since there exists extensive

4
variations in the terminology, these definitions have been compiled, where

available, and are presented in Appendix B.

The name of the department or agency responsible for the administration

and enforcement of each State’s manufactured building regulatory program

along with the address and person that can be contacted for further information are given in Appendix C.

PURETO RICO - • Puerto Rico has not enacted legislation or prepared

regulations applicable to manufactured building

construction. However, this does not mean that they

do not permit them or allow unregulated erection of

manufactured buildings. They are permitted and plans

are reviewed on a case by case basis for conformity

with their Building Code as alternate construction

materials or construction methods. Their building

regulation is based on the Uniform Building Code.

The burden of the proof as to the suitability of

materials and methods used in the construction of

the building lies on the petitioner who must prove

with reports from recognized laboratories the

resistance and characteristics of materials and

methods used. Proof must also be presented that

the building resists lateral forces for hurricane

winds of 150 m/hr and the resistance to tremors for

a zone 2. Foundations, anchorage, and service

installations are reviewed for compliance in each

particular case.

INSTRUCTIONS FOR USING CHART 1

All buildings, except H, I, and J occupancies, shall be constructed so that

the calculated heat loss through wall and roof areas, when converted to BTU per

hour per cubic foot of volume shall not exceed the figure taken from the attached

graph.

HEAT LOSS CALCULATIONS

Heat loss through walls shall include the transmitted heat loss through all

wall areas above grade, including window and door openings.

Heat loss through roof shall include the transmitted heat loss through all

roof areas, including skylights and other openings.

Note : If the space between the roof and ceiling is used for supply or return

air,'*' the heat transmission coefficient used shall be the same as if there were

no ceiling.

Temperature difference shall be the inside temperature to be maintained

o 0 plus 10 F. (Outside design temperature = 10 F.)

BUILDING VOLUME

For purposes of reference to attached chart, building volume shall be the total

volume within the exterior wall surfaces from the lowest floor level to the highest

ceiling level, except that the maximum floor to ceiling height of the top floor or

only floor of one story building shall not be considered to exceed fifteen feet.

Note 1: The top floor ceiling and "Plenum" is considered part of the total roof

unless the plenum contains uninsulated ducts or piping, or is used as a

supply or return air plenum.

MEMORANDUM

TO: All Approved Testing Facilities, Approved Manufacturers, and Local

Governments

FROM: Dillard E. Bryant, Director, Codes Administration

SUBJECT: Revised Codes for Industrialized Buildings

As provided for in Sections 266EE 3(A) and 257J(b) of Article 41 of the

Annotated Code of Maryland (1955 Replacement Volume, 1970 Supplement), the Department of Economic and Community Development held a public hearing on the adoption

of the 1975 BOCA Basic Building, Plumbing, and Mechanical Codes and the 1975

National Electrical Code.

Based on this public hearing and the advice of the Advisory Commission on Industrialized Buildings and Mobile Homes, the Department has made the following

adoptions which are effective as of January 1, 1976.

1. The 1975 editions of the BOCA Basic Plumbing and Mechanical Codes have been

adopted without any modification.

2. The 1975 National Electrical Code was adopted with one modification. Section

336.3 has been modified to delete the limitations contained in the initial

sentence. The modification reads: "Type NM and Type NKC Cables shall be

permitted as follows:’’

3. The 1975 edition of the BCCA Basic Building Code has been adopted with certain

modifications, only a few of which apply to one and two family dwellings.

These are as follows:

a. Section 316.0. "Ihysically Handicapped and Aged" is deleted and the

Maryland Code for the Handicapped is substituted. Note this does not

apply to one and two family units unless they are part of a multifamily

project

b. Section 625.3. Identification of Hazardous Exits is deleted because it

conflicts with the Handicapped Code.

c. Section 857 . 5 . 6 . 1 . Add to item 3 the following "or whose least dimension

is 18 inches or more.

e. Section 924.4 Balconies. Add the following sentence: "Because of the

danger of deterioration due to weather and lack of adequate maintenance,

all structural members supporting balcony decks shall be of metal,

reinforced concrete or decay resistant wood such as cedar or cypress or treated wood as approved by the building official.

In Bulletin 7/ 6 , paragraph 4, issued April 11, 1973, the wind load requirement was specified for all industrialized buildings as requiring design to withstand

a 25 lb. per square foot horizontal wind load. For uniformity, this requirement

is still retained.

All industrialized buildings fabricated after January 1, 1976 must conform

to the above. Approved Test Facilities are requested to review the plans for

each manufacturer for which they are the Appproved Test Facility and send a letter

to this office confirming that the plans have been modified as may be necessary

and that future construction will be in compliance with the above 1975 code

editions.

MEMORANDUM

TO: All Approved Testing Facilities, Approved Manufacturers, and Local

Governments

FROM: Millard E. Bryant, Director, Codes Administration

SU3JECT: Revised Codes for Industrialized Buildings

Reference is made to our memo with the above subject dated December 18, 1975

which announced the adoption of the 1975 3CCA Basic Building Code.

Although no objection was raised at the time of the public hearing,

Section 612.3 contains a major increase in the minimum size of single doors. In

the 1972 code cycle, the minimum size for single doors was modified in Section

614.2 to provide not less than 23 ,; clear width, which has resulted in the normal

use of 30!: wide doors. The new requirement in Section 612.3 is a clear width

of not less than 32” and this would have an effect on corridor widths also. It appears that this new requirement came from consideration of increased convenience

for wheelchair users, but it is believed that the intent was to exempt one and

two family dwellings from this requirement. Numerous calls have been received

from manufacturers concerning this increase with request for delay in putting it

into effect.

There will be a meeting of our Advisory Commission on February 3, at which

time this requirement will be discussed and there is the possibility that the

code will be modified to retain the minimum clear width as 28". Pending further

advice, which should be issued no later than February 15, Approved Test Facilities

and manufacturers are authorized to continue using the clear width of not less

than 2g for single doors.

Where

V Volume in cubic feet per minute

P *> Difference in pressure in pounds per square inch

D = Inside diameter of pipe in inches

W = Weight of air in pipe in pounds per cubic foot

L = Length of pipe in feet

Note: This equation is derived from Fanning's equation using values

in units of measurement as indicated.

This formula is the basis for sizing at 15 inches HG. Vacuum, as provided in Table P-1U07 • 322c . It is a designer's prerogative to use a different design, pressure, and size according to the formula, if his

results are within the established limits. The manufacturers will

probably include this information in the engineering data for their

equipment, and may also include ratio conversion factors or charts for sizing at various pressures.

MANUFACTURED BUILDING CODE LETTER NO. 1

To: Building Manufacturers

From: Herbert W. Meyer

State Building Inspector

/y

Subject: INSTALLATION OF COMPOSITION ROOFING SHINGLES

The submission of plans for manufactured buildings to the Building

Code Division has indicated that compliance is not being made with

Section 3203(d) 2

" Composition Shingles Composition Shingles shall

not be installed on a roof having a slope of less than four (4) inches

to twelve (12) inches unless approved by the Building Official."

Because of the low slope roofs being used in manufactured buildings

alternate methods to those allowed in UBC Standard 32-3 must be used.

We are writing to inform you that composition shingles installed in

accordance with the recommendations of the "Asphalt Roofing Manufacturers Association" for "Low Slope Applications" will be acceptable

to the division. A copy of such recommendation is attached.

In addition the division will accept other methods if they have been

proven by use or test. Such use or test must show the roof covering

will provide weather protection for the building at the roof.

The division will accept approval of low slope roof applications if

examined and approved by an "Evaluation Agency" approved oy this

division.

A- 122
- Hip and ridge shingles applied with hex tab strips.

HOW SLOPE APPLICATION

Squar-e-tab strip shingles are recommended for use on decks having

a slope lower than 4" per foot but not less than 2" per foot when

special application methods are used to compensate for the slower

water run-off resulting from the lower roof slope. These application

methods involve:-- (a) double unde r lay m ent ; (b) a special cemented

eaves flashing strip; (c) use shingles provided with factory applied

adhesive and manufactured to conform to the Underwriters'

Laboratories' 1962 Standard for Class "C" Wind Resistant shingles,

or, if "free" tab square butt strips are used cement all the tabs.

Application of No. 15 asphalt saturated felt underlay

on a Low Slope Deck.

(a) Underlayment

‘Die deck is covered with two layers of No. 15 asphalt saturated felt,

applied as shown. The application begins with a 19" startc

course laid along the eaves followed by a 5 6" wide sheet laid evi. n with the eaves arid completely overlapping the starter course.

A- .125
Exhibit //13 , Minnesota

Thereafter, 36" sheets arc laid, each to overlap the preceding course

by 19", exposing 17" of the underlying sheet. The felt is secured to

the deck with only enough fasteners to hold it in place until the

shingles are applied.

(b) Eave Flashing

Under the conditions outlined in paragraph (d), page 39, that portion

of the felt underlay that extends from the eave up the roof far enough

to overlie a point 24" inside the inside wall line of the building is

treated as follows:

- Underlay plies cemented

together to form an eaves

flashing.

A continuous layer of plastic

asphalt cement is applied at the

rate of two gallons per 100

square feet to the surface of the

underlay starter course before

the first full course is applied,

and also to the 19" underlying

portion of each succeeding course

which lies within the eaves flashing area, before placing the next

course. It is important to apply

the cement uniformly with a comb trowel, so that at no point

will felt touch felt when the application is completed. The overlying sheet is pressed firmly into

the entire cemented area.

(c) Application of Shingles

Any shingle arrangement as described for normal slope application

may be used. The exposure is 5" and the number of nails required

per strip is four.

Nebraska's standards for manufactured housing units.

If the Initial Inspection reveals deviations from the previously

A-152
approved compliance assurance manual and plans* the Inspection

agency shall notify the manufacturer. In writing, of deviations,

specifying in detail the observed deviations. A copy of this

letter shall be sent to the Nebraska State Health Department.

Upon notification from the plant that the specified deviations

have been corrected, the inspection agency shall again make an

initial Inspection of the plant following the procedure

outlined above.

11. Monitoring In-Plant Inspections. Following notification to a

manufacturer under 1. above, the inspection agency shall undertake monitoring in-plant inspections on a frequency sufficient

to assure continuing compliance with the manufacturer's compliance

assurance program. The factors which the inspection agency shall

take into consideration in determining this frequency of monitoring

in-plant inspections are as follows:

A. Production Volume

B. Design Complexity of Units

C. The qualifications of the manufacturer's own in-house compliance

control organization.

D. The experience record of the manufacturer.

The monitoring in-plant inspection shall utilize the in-plant

inspection check list in part (c) above to assure that each

construction feature (structural, mechanical, plumbing, and

electrical) is fully evaluated.

RE: NEVADA FACTORY HOUSING REGULATIONS

Dear Mr. Duncan:

Enclosed is a copy of Nevada Revised Statute sections 461.030

Declaration of Legislative Intent and 461.170 listing the

adopted codes and standards applying to factory housino

and manufactured building or components. We are currently

using the 1973 editions in all categories excepting the

National Electrical Code. The 1975 Edition of the National

Electrical Code was adopted as a statewide standard by our

last legislative session. As these adoptions are statutory,

we are restricted to their use only and reciprocity with other

model codes can only be achieved if the reciprocity code

is more restrictive, an option granted to local authorities

by law.

In addition, our state regulation will not allow aluminum

wiring for branch circuits under 30 ampere rating. We, also,

require exterior wall systems be 20 minutes rated from fire

penetration. Panalized wall systems must be approved by the

State Fire Marshal's office prior to use in construction.

If you have further questions please contact our office.

Yours truly.

component parts may be mechanical cores, floor, ceiling, roof, wall or partition panels either individually or in any combination thereof, or may

include plumbing, electrical or mechanical systems or devices. The Board

has further interpreted that Factory-Built Housing does not include those

products which might be considered as closed construction such as precast

or pre-stressed concrete beams or columns or laminated wood beams, arches

or columns inasmuch as such products are usually designed under industry

or commercial standards and the quality controlled by professional engi- neers on a job by job basis, hence no need to impose an additional state

control
