Substantial Improvements/ Damage Flashcards
What is the basic rule for substantial improvements?
If costs of improvements, or costs to repair damage exceeds 50% of the fair market value of the building, it must be brought up to current floodplain management standards.
Substantially improved dwellings that meet the basic rule must be treated the same as new construction , True of False.
True
Define substantial improvement.
Reconstruction, rehabilitation, addition or other improvement to a structure, the total cost of which exceeds 50% of fair market value before the start of construction.
Can a developer segment a project to avoid having to upgrade to current flood management standards.
No, in fact some communities require a 5-10 year look back and improvements are calculated cumulatively. When they total 50% the building must be brought into compliance as if it were new construction.
The substantial improvments rule covers both pre-FIRM and post-FIRM buildings. True or False.
True, post-FIRMS should already be compliant with regulations for new construction, but the BFE may have been elevated, or zone boundary changeed if FIRMS are updated.
what is the formula to determine if a project is a substantial improvement.
cost of improvement /market value of the building >=50%
What costs must be included in the formula?
all structural costs, materials, labor, overhead, profit, built in appliances and repairs made to damaged parts of the building being worked on at the same time.
what are the 2 exemptions from the substantial improvement requirement?
projects that are historical buildings and improvements to code violations
How is market value determined?
Based only on the structure, not the land, location or detached accessory structures. Price is what seller and buyer agree to. Based on condition before repairs and similar units of similar size.
what costs must not be included in the formula
plans and specs, survey, permits, post storm clean up, and all outside improvements.
When should you get more exact estimate of fair market value of structure.
Use available data to screen, if the ratio is close (40-60%) it is worth getting a more precise market value.
What is a minor rehabilitation?
improvements made to existing structure that does not increase the external dimensions and is less than 50% of fair market value does not need to be elevated, however if it is, or if flood proofed, insurance rates are lower.
What is the benefit from incorporating methods to reduce flood damage even if not required as a substantial improvement project.
Flood insurance rates will go down and property will be better protected. (i.e. use flood resistant materials, elevated electrical, heating and AC above BFE).
What is substantial rehabilitation
If the rehabilitation cost more than 50% of the value of the building, the project must be brought up to floodplain standards (elevated or basement filled)
If a residential addition is added laterally do the same substantial improvements requirements apply
Only the addition needs to be elevated if the original structure improvements are minimal (existing common wall is also maintained). If the common wall is demolished, both the original and addition must be elevated. However, if building is in the V zone, both must be elevated for any time of addition, due to “free of obstruction “ standard.
If commercial addition is added laterally, do the same substantial improvements requirements apply?
the addition may be either elevated or floodproofed, wall between the addition and original building must also be floodproofed.
What is the free of obstruction standard.
In a V zone, if an addition is placed on a building, both must be elevated no matter what. Otherwise, the lower existing structure would create a storm surge, causing damage to the addition.
What is the substantial improvement rule for a vertical residential addition?
If a full or partial second floor is added, the entire structure must be elevated. Otherwise, failure of the existing building would result in failure of the addtion as well.
What is the substantial improvement rule for a vertical nonresidential addition?
If a full or partial second floor is added the entire structure must be floodproofed or elevated.
What is the substantial improvement rule for a minor addition to a Post-FIRM building.
all additions to post-FIRM buildings are treated as new construction and must meet all requirements. If minor addition is not substantial improvement, must be elevated at least as high as when BFE went into effect. Minor additions to nonresidential can be floodproofed.
What is the substantial improvement rule for a minor addition if a map revision has taken place and the BFE has increased?
only additions that are substantial improvements have to be elevated to the NEW BFE, or floodproofed (non residential)
What is the definition of substantial damage?
Damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damaged condition would equal or exceed 50% of the market value of the structure before the damage occurred.
What are 2 key points that apply to substantial damage projects.?
Damage can be from any cause, natural or human induced hazard. Substantial damage rule applies to all buildings in a flood hazard areas regardless of whether it is covered by flood insurance.
What is the formula to determine if a project is substantially damaged?
cost to repair/market value of building => 50%
