(1) who typ enforces codes (2) which code do local/state jurisdictions use for comm const. (3) who publishes these codes | (1) local authority having jurisdiction (2) (IBC) International Bldg Code (3) (ICC) International Code Council ^ ICC also made complementary code for resi const., existing bldgs, energy conservation, fire protection, green const., plumbing & mech systems, swimming pools & spas |
How can states adopt the code? | -States can adopt all/some chapters, all/some/none complementary codes, have old or current version, &/or modify sections/add requirements -Ex consider a state can enforce enviro protection rules even though it's own state bldg code may not regulate enviro impact |
IBC incorporates ANSI A117.1 which is what? | "Accessible & Usable Buildings & Facilities" -governs accessibility req. |
Why must a design consider bldg code during the planning phase? * Predesign phase req. architect to determine: | -In order to make a budget Ex: determining the const. type or seismic loading -which local, state, federal regulations apply -* see pg 8-3 for partial list of regulatory agencies & code provisions that can apply to a project |
Federal Regulator Agencies -include: -most notable: | -include military const., fed prisons, specific area of const. like glazing safety req. issued by (CPSC) Consumer Product Safety Commission -most notable is (ADA) Americans w/ Disabilities Act |
(ADA) Americans w/ Disabilities Act is based on: What is unique about ADA? | -based on (ANSI) American National Standard Institutes ^ ANSI Standard A117.1, Accessible & Usable Bldg & Facilities -ADA is not code or standard, it is a civil rights legislation |
State Regulations -In addition to IBC, states can enforce their own: | (1) energy codes (2) elevator const. req. (3) enviro reg. (4) fabric flammability standards (5) rules specific to state govt bldgs, institutions, oth facilities, hospitals, nursing homes, restaurants, schools, sim. |
State Regulations Cont' -How often does the ICC update the IBC? * -When does a state need to adopt the updated IBC? | -ICC updates the IBC every 3 years -after an update a state has NO TIME LIMIT to adopt it, state decides when to adopt updates or even use IBC at all -remember- a state can create their own code |
Local Regulations -local code usually includes: | -amendments to adopted bldg code to address specific needs of a geographical region or alleviate local problems -Ex higher snow load factor in roof for maintenance area |
Building Code History -Dates back to when? -Where were the first laws governing const. seen? | -dates back to 2000BC - Babylonian Code of Hammurabi -Greeks & Romans had various laws - The Laws of the Twelve Tables included setback req. for repair access & preventing the spread of fire |

Practice Question Which does ADA address? (1) width of exit stair (2) max # of bldg stories (3) max occupancy of a floor (4) # of barrier free pkg spaces | (4) correct -IBC addresses 1-3 |
Legal Basis of Codes -Why can code vary among states? | -the 10th Amendment of US Constitution gives states power to adopt & enforce bldg codes -this is why code varies among states, they can also delegate some powers to local govt like counties or cities -MOST OFTEN bldg codes are adopted & enforced by local govt (municipality/county/district) |
Legal Basis of Codes -Codes are enacted as laws; so before const. bldg code is enforced through the permit process: | -builders submit plans & spec's to (AHJ) Authority Having Jurisdiction for checking & approval before a permit is issued -during const. AHJ (unless govt project) conducts inspections to check bldg matches approved plans |
Legal Basis of Codes * What is the architect's legal responsibility? | - architect responsible for designing bldg in conformance w/ all applicable codes & regulations b/c by registration laws, their job to practice lawfully in order to protect the health, safety, & welfare of the public |
"model code" | -written by a group of experts knowledgeable in the field, no particular geographical area -affordable way for city, county, district to have complete code w/out difficulty/expense to write it's own (can adopt w/ modifications) |
The primary model code is: | -the IBC - currently jurisdictions in all states have adopted one or more of the family of international codes -this has brought helpful consistency to work across the country |
Life Safety Code VS NFPA5000 Bldg Const. & Safety Code 2002 | -from National Fire Protection Association -use by many states -NFPA wrote it's own code, but has not seen widespread use |
IBC testing refers to: | -refers to nationally recognized standards of mat. & testing -innovation/advancement is allowed if new/untested mat. can pass performance based testing req. |
* Why are bldg codes written? -How are model codes written? | -to protect the health, safety, & welfare of the public -based on idea of least acceptable risk = min level needed for bldg & occupant safety |

(1) non-city zoning includes: (2) zoning is based on occupancies like: (3) each zoning districts specifies: (4) can a zone only be used for it's own purpose? | (1) airport use, agricultural vs forestry vs recreational use, floodplains, historic area (2) resi, commercial, industrial occupancy ^ (Ex-resi can be single home to high density multi-home dwellings) (3) specifies permissible uses (4) it can be used for it's own purpose or a use listed in one more restrictive |
Site Specific Regulations "easements" | -right to use another's land for a specific purpose or prevent land owner from using it for specific purpose -common ex is "utility easement" where utility co. can run abv or blw ground lines, place equip, prevent permanent structures |
Site Specific Regulations (1) "access easement" (2) "support easement" (3) "joint use easement" (4) "scenic easement" (5) "conservation easement" | (1) land parcel not served by public road, this gives owner public right to cross an adj property (2) const. of common party walls btwn property (3) 2 or more prop. owners to share common features like a driveway (4) protect views/ develop. in scenic areas (5) limit land use in large areas (used by public agencies to ctrl land use w/out purchasing land) |
"ROW" Right-of-way | -legal right of one party or public to traverse land belonging to another (ex streets or sidewalks) -boundary is typ adj property owner -"access easement" creates a private or public right-of-way |
Deed Restrictions (1) what is the general understanding? (2) how long are deed restrictions typ est for? (3) "restrictive covenants" | (1) deeds to property can contain provisions that restrict the use of the property by the buyer (2) most est for specific time period of 10, 15, 20, 30 years (3) these are legal & enforceable, common type for developers of large land areas, can include setbacks, min house SF, mat. allowed on exterior, etc |
Deed Restrictions Cont' (4) "affirmative covenant" (5) "conditional covenant" | (4) req. a buyer to perform a specific duty in the future (Ex construct & maintain a fence) (5) permits the title to property to revert to original owner if restrictions prescribed in deed aren't followed |
