For some time I've been saying that my largest single line item in my cost breakdowns was the one labeled "Government fees and costs", may here doubted that it costs so much to permit a home in the Golden State.Fire Marshal said:To discuss a case in point, a city (not named) in California now charges in excess of $100,000 in local fees for every new home. A new home in this city sells for $250,000-$350,000. The California Building Industry Association contends that there are a great many jurisdictions charging fees at the same rate, or higher.
Fire Marshal said:108.6.1 General. Subject to other provisions of law, a city, county, or city and county may make changes to the provisions adopted by the Department of Housing and Community Development. If any city, county, city and county does not amend, add or repeal by local ordinance or regulations the provisions published in this code or other regulations promulgated by the Department of Housing and Community Development, those provisions shall be applicable and shall become effective 180 days after publication by the California Building Standards Commission. Amendments, additions and deletions to this code adopted by a city, county, city and county pursuant to California Health and Safety Code Sections 17958.7 and 18941.5, together with all applicable portions of this code, shall also become effective 180 days after publication of the California Building Standards by the California Building Standards Commission. (2007 California Building Code [CBC] and 2007 California Fire Code [CFC)
But what about the custom builders like me, I've never built a home with less than a 5' setback, most homes have had 15' to 25' setbacks. In order to sell sprinklers they are recommending cramming people together with 2' setbacks! That's the trade-off, mandate sprinklers to save lives but cram people together like sardines in a can?Recommendations said:The California Building Code required a three-foot side yard setback for homes for many years. The 2007 California Building Code increased the setback requirement to five-feet, increasing the level of safety and property protection. The existing fire loss data in California is exclusively based upon the three-foot setback data.
It is reasonable to state that the installation of the automatic fire sprinkler systems in homes will achieve the same safety and property protection benefit as the five-foot setback when fires start within the sprinklered areas of homes. In instances where fires start on the exterior of structures, in the attics, or in wildland-urban interface (WUI) areas, the fire loss data will remain unchanged to the historical fire loss data in California. Builders are able to reduce lot widths by four feet (two feet from each side lot line) with this setback reduction. The reduction will allow builders to maximize the number of lots when dividing a tract into buildable lots. The market trend is for buyers to purchase larger houses on smaller lots. The reasons for this trend are beyond the scope of this report.

Reading the report, I get the sense that there was a lot of input from builders of tract homes, fire officials, and building code officials -- but very little input from homebuyers, custom home builders, or economists.conarb said:But what about the custom builders like me, I've never built a home with less than a 5' setback, most homes have had 15' to 25' setbacks.
Jasper:The said:The Fire Protection Research Foundation, principally sponsored by the National Fire Protection Association (NFPA), conducted a study to more accurately determine the cost of fire sprinkler installation in new construction nationwide. The average cost was $1.61 per sprinklered square foot, not including offsets or credits *pg. 5, derived from costs ranging from$.038 to $3.66. The average homeowner insurance reduction due to the presence of the automatic fire sprinkler system was 7% *pg. 29.
There is an economy of scale that needs to be applied to the installation of fire sprinkler systems. One-time costs for tracts include project estimation, drawing of plans, and the plan review process.
Also, materials can often be purchased at better negotiated rates when purchased in bulk. Many, if not most, homes today are built in tracts as opposed to the traditional single custom home model. Some savings can be achieved by standardizing plans. Standardization is the equivalent of creating "boiler plate" sprinkler system designs for homes to be constructed by one or more construction companies in more than one jurisdiction.
I can think of a few reasons:conarb said:They make a point of saying that the vast majority of home built today are tract homes, so why not exempt custom homes, homes built in WUI areas, and homes served by wells?
* It is too easy to abuse a "custom home" exemption. Tract home builders have a budget for legal fees, and I am sure they could come up with a boilerplate way to categorize every house they build as a "custom home", no matter how you defined "custom home".Jasper said:conarb said:They make a point of saying that the vast majority of home built today are tract homes, so why not exempt custom homes, homes built in WUI areas, and homes served by wells?
I dropped out of the NAHB in the early 70s, the tract builders held all the power because their dues were much higher (charged by the square foot permitted) and when they started talking building disposable homes for repeat business I got disgusted. There is no organized group of custom builders, the best contractors' association is the AGC but they don't build homes.Jasper said:* There do not seem to have been any custom home builders on the committee to give their input.
Sprinklers do no good when the fire is coming from the outside, I've often wondered why they don't require sprinklers on the outside, I'm sure the reason is that Tyco and the other manufacturers don't make external sprinklers. On the home project I'm working on now I've hired a fire consulting firm, I'm getting all kinds of recommendations, foam systems around the perimeter with special foams on the decks, but no internal sprinklers.Jasper said:* Do homes in "Wildland-Urban Interface areas" have an even greater need for sprinklers? Granted, current codes require that their exteriors be fire-hardened, but they also tend to be further from fire stations, and often burn down in bunches.
