Housing Basic Housing Planning and Inspection Physical Processes of Planning Implementation
Introduction • Housing – The absolute core building block of community • If you cannot achieve sustainability in your housing base – effective community can never be realized • Work – Shelter - Dignity
The Dimensions of Housing • 1. AFFORDABILITY • Acquisition and Possession of Shelter is the single most expensive obligation for the vast majority – it is typically a person’s greatest source of wealth • Affordability is measured within each country and in numerous sub districts as the percent of individuals that can afford to acquire shelter for the first time • Affordability is the percent of income that can be applied to the carrying cost of housing • Shelter, therefore, must be tiered to an affordability index and translated into demand and supply – the current “sweet spot” is $85,000 to $92,000
Percent of Population at the Median Income Qualified to Purchase the Median Price Home
And, The Have Nots • In 2001, there are 178,638 know persons you are homeless • The actual number is much high since this is the count of persons using public and private shelters
Dimensions • 2. Supply - Type • Public v Private Housing • Single Family Housing (owner – rental) • Multi-Family Housing • Cooperative Housing • Public Housing • Co-Housing • Shelters (including motels) • Sweat-Equity Non Profits • Manufactured housing
Dimensions • Trickle down supply • Assumes that supply has a rapid turnover • Projecting Needs • Monitoring the Condition of Housing
Projecting Needs • Projecting population • Sectoring into demographics • Modal Split – sectoring demographics into the type of housing now supplied • Determining the number of units that will leave the housing base • Projecting the total housing need • Finally, determining the modal split of housing to be supplied
Some Basic History – Basic Housing Codes and Regulation Jacob Riis Disastrous fires and unsanitary conditions led to the adoption of housing construction codes during the Colonial Period. Codes centered in roof and chimney composition. Most homes required to be constructed from stone or brick. 1626
Neighborhood Sanitation • Basic sanitation practices are linked to the development of housing codes. • Outdoor toilet location • Food and draft animals in municipal locations. • Link to the rise of public health agencies in the 1870’s
First Tenement Housing Act • New York City – 1867 • First Comprehensive Housing Act • Attacks the problems of light, air, access and sanitation • Stairs must have banisters • Water closets required – 1 : 20 occupant ratio to water closet
Tenement Act of 1882 • Amends Act of 1867 • Requires running water to every floor in a tenement building • Trinity Church of Manhattan largest tenement owner – gross violations • City brought enforcement but courts refused to convict – no evidence that running water is essential to life and safety of residents
Benchmark Legislation The year 1892 marks the formation of a major movement for housing reform in the United States. Jacob Riis and a host of reformers To pass the Tenement Reform Act of 1901. This landmark legislation is the origin of all housing, sanitation, and live safety codes in the United States.
Tenement Reform Act – What It Contains Minimum Room Size More light and air Maximum Occupancy Fireproofing for structures No basement dwelling 8 :1 water closet Potable water supply
Federal Involvement • Congress authorizes funding (under T.R.) to conduct a major investigation of housing conditions in the U.S. • The report is another landmark • Discloses the scandal of American housing • First report to actually collect data linking poor housing conditions to health and safety.
Further Federal Actions • FDR commissions a second federal report in 1932 • Reports the shocking news that ½ of the nation is ill fed, ill clothed, and poorly housed • Fed. Gov. launches the Federal Housing Administration (FHA) and begins leading the way for housing reform and inspection
Federal Reform • Veterans Administration • Home Loan Bank Board • Federal National Mortgage Admin. • Public Housing Administration • Public Works Administration • Slum Clearance Act of 1937 and 1949
Housing Inspection Reform • With the federal entrance into the housing market, the process of development housing codes, inspection programs, and health rules became a requirement for all states that participated in the programs.
Housing Inspection - Purposes • First – to provide safe, decent, and sanitary housing • Second, to create a mandatory system of regulations that force housing owners, to maintain their premises under minimum standards • Enforcement Overview - http://aalto.arch.ksu.edu/jwkplan/planimp/enforcement1.htm
Housing is More Than Just Condition – The CDU • CDU Index • Condition – physical useful life • Desirability – meets current needs • Utility – suitable for median standards • Web Site - http://aalto.arch.ksu.edu/jwkplan/planimp/CDU.htm
Housing Inspection Process • The Components of Shelter • The roof and upper supporting members • Sidewalls – including windows and doors • Accessories – including porches and add-ons • The basement supporting structure • Condition and maintenance of environment • The land use - # of units • Parking supply • http://aalto.arch.ksu.edu/jwkplan/planimp/residential_inspection_forms.htm
Construction Codes and Minimum Standards • Building and Structure • Minimum Standards • Detailed Materials • Life Safety – Fire • Life Safety – Health and Sanitation • Dwelling and Occupancy • Access and ADA
Minimum Housing Standards • Created to set a standard that is at the very minimum of human habitability • Delineates a dwelling unit from a sleeping room • Sets a standard for efficiency rental housing • Sets a minimum set of guidelines for housing adaptation • See: http://aalto.arch.ksu.edu/jwkplan/planimp/minimum%20housing.htm
Building & Structure Codes • UNIFORM BUILDING CODE SYSTEM – UBC • CLASS OF STRUCTURE • GROUP A • Assembly of 1,000 or more • Assembly, less than 1,000 with stage • Assembly 300 – 1,000 without stage • Less than 300 without stage • Stadiums

The Process • BUILDING PERMIT APPLICATION • APPLICATION FOR PLAN COMPLIANCE CHECK • PLAN CHECK • COMPLIANCE NOTICE • PERMIT ISSUED • INSPECTION ROUTINE • OCCUPANCY PERMIT
Plan Submission and Plan Check • Three complete sets of fully dimensioned plans which include: • Plot/Site plan • Foundation Plan with Steel Reinforcement Details • Floor Plan • Cross Sections • Roof Plan • Cross Sections • Structural Details • Two sets of Title 24 Energy documentation (Certificate of Compliance sheets CF-1R, MF-1R and MF-1R must be reproduced on actual plan sheet) • Two copies of engineered truss details (if roof design has a truss system) • Two copies of engineered structural calculations (if non-conventional framing) • Two copies of soils report (an additional two sets of plans are required for projects utilizing post tension foundation design) • Single line diagram for electrical services over 200 amps
Detailed Material & Inspections • EXAMPLES • Concrete bagging; strength; covering; slumping • Framing; schedule and joining • Roofing – materials ½ OD – 4 corner rafter nailing • Fire place – 14’ run with triple stack offset 16” from enclosure • Insulation – materials and schedule for walls and ceiling • Truss, wall, joints – material sizes, treatment, strength
SOUTH ORANGE, N.J. (AP) -- As the fire alarm blared throughout the dark dormitory, most students chalked it up as another false alarm, turned over and went back to sleep. ``I thought it was a joke,'' said Pete Tornatore, 18. Life Safety - Fire THE B.O.C.A THE N.F.P.A.C.
Nat. Fire Prevention & Safety Association THE BASICS - Adequate exits without over dependence - Construction integrity during fires - Adequate emergency lighting - Early warning - Backup and redundant systems - Enclosure of vertical openings
Fire Safety - Materials • Fire resistant materials • Non/combustible • Fire Proof • Class A, B, C explosion suppression areas • Measured in closed cup, flash point temperatures • Basic safety – mobile fire extinguishers • Fixed fire suppression – dry • Fixed fire suppression - sprinklers
Life Safety – The B.O.C.A • THE BASICS • Exits • Exit size, direction, composition and distance • Alarms • Type, placement – based on hazard classification -Minimum • Low • Ordinary and High
Americans With Disabilities Act • CONCEPTS • Reasonable Accommodation!!!!!! • Parking • Access to Buildings • Access within Buildings • Components, aids, dimensions http://aalto.arch.ksu.edu/jwkplan/planimp/ERRORS.PDF
Conclusions • The most complicated and inter-related aspect of physical planning on the town level deals with the provision of housing and construction compliance • Construction and implementation are only a first step. Regulatory compliance is critical for a sustainable housing base • Slum landlords ARE US
