What Are the Requirements for Installing Stairs in Single Family Homes in Denver
Should You lot Pop the Top on Your Home?
That is the question many Denverites are pondering as they residuum the demand for more space with the challenges of inbound the city's competitive housing market place. Hither, local contractor and pop-acme expert Justin Bride offers helpful insights and advice.
It'southward a common conundrum: Your Denver bungalow was cozy when you bought it, simply is downright cramped at present that your family has grown—and spent the by yr cooped up together inside. Practise you sell it and hope to score a new business firm of your dreams in Denver'south competitive market—assuming the proceeds can embrace the cost of sizing up in a urban center where the boilerplate single-family domicile toll is quickly approaching $675,000? Or do y'all piece of work with what you have past finding ways to stretch your square footage?
Justin Helpmate, principal of Ascent Contracting, Inc., has helped many clients navigate the latter path since founding his Denver-based residential and commercial contracting company in 2012, and has become a proponent of the practice along the manner. "Popping the peak gives homeowners the opportunity to accept a make-new house in a historic neighborhood or an area of boondocks that they already have grown to dear," he explains. "Near of the time, people desire to open up up their whole first floor, and having that pop top to accommodate bedrooms actually justifies creating the first-flooring layout you've always envisioned. It gives yous more of a blank slate and then you tin get what you desire—a really functional and energy-efficient dwelling house where there wasn't i before."
While many people associate popping the meridian with removing the entire roof to accommodate a full 2nd story, Helpmate notes that smaller projects can have a big affect, as well, from incorporating dormers to transform a partially used 2nd flooring into a spacious bedroom suite, to adding a back-of-house addition with a rooftop deck.
Imagining the possibilities is the like shooting fish in a barrel part. For help with the applied considerations, we asked Bride to share his insights and advice:
5280 Dwelling house: What are the benefits of vertically expanding a home?
Justin Bride: Any time y'all add together square footage to your dwelling, especially in today's market, you're calculation value to your belongings—whereas with an interior remodel, the value add together may be more than subjective. One of the reasons why [popping the top] is so prevalent in the city of Denver is that if there are site constraints—a smaller lot, or office of the site is already occupied by a detached garage, which you run across all over Denver proper—sometimes it makes more sense to go vertical to get the foursquare footage yous want.
Does it toll less to build vertically?
In terms of the cost-per-square-human foot price for new structure, it'due south like to go up versus out. However, this cost is ever closely related to the nature of the remodel—in particular, how much remodeling of the existing foursquare footage needs to be done to accommodate the new square footage. Sometimes, a unmarried-story, or even double-story, back-of-house improver can be less expensive than a popular top on a per-square-foot basis because the owners may not need to remodel their existing home, resulting in a lower overall project cost.
In Denver's hot housing market, tin can homeowners look to speedily recoup their investment in a pop summit?
It would be fantastic if they could recoup all of their structure costs by the time the project is washed. But it's safer to hope that within ii to five years, they will have recouped all of their construction costs and exist net positive—with the agreement that everything is marketplace dependent. We know that the property values of homes with pop tops we've done in 2016 and 2017 are already much higher than the owners' total investments.

Does popping the top have less time than expanding outward—or even starting from scratch?
Building a new business firm requires the longest timeline: When we practise a scrape-and-build, we project 12-14 months, and sometimes they go over that. Our pop tops tend to fall below a twelvemonth, but anymore—because there's so much need, not to mention the challenges of getting materials in the COVID world—below 10 months is a pretty aggressive schedule.
Edifice out [with a new addition] tin can have a like overall timeline. Our back-of-house additions might peak at 9 or 10 months and can exist six to eight months. Merely with a back-of-house improver, the homeowner has the ability to alive in the house for a certain portion of time. With a popular elevation, you really have to be out the entire time for everyone'due south safety.
What are the structural requirements for a popular top, and does the typical century-sometime Wash Park bungalow come across them?
Many Denver houses, peculiarly those that were congenital between the early 1900s and about 1930 or so, were really well built. Whether they take brick or concrete foundations, they tin about ever adapt a popular pinnacle. In the best-case scenario, if all the weather condition are right and the firm was congenital later than the mid-1920s, which was when they started to use concrete foundation walls with continuous footers, there doesn't have to be anything done structurally to accommodate the popular top. But most of the time, it'south practiced to anticipate that light to moderate foundation support will exist needed, in the form of helical piers or concrete pads.
Is information technology necessary to rent an builder?
For a pop top, an architect is really necessary because we're adding square footage, there are rooflines and stairways to exist considered, and most importantly, we're stylistically blending erstwhile with new, which requires expertise. That's not to say that a homeowner needs to start by engaging an architect. It's only equally good to appoint a reputable contractor, who can and so recommend an architect and start the project collaboratively.
Who hires the structural engineer?
The builder facilitates working with the structural engineer because structural blueprint is typically part of the architectural pattern phase. The same is truthful with mechanical design, equally in HVAC design. That wasn't a necessity a few years ago, but in 2018, Denver began requiring a certain level of mechanical design with any project adding more than than 30 percentage to the existing square footage.

Speaking of rules, does zoning limit how much you lot tin can expand?
Admittedly. In addition to setback requirements, at that place are two large factors that come into play: Most of the Denver residential zoning classifications limit edifice coverage such that you tin only take about 32.5 percent of your lot covered with a covered space. So, if you take a x,000-square-foot lot, your business firm can only have a 3,250-square-foot footprint. If you have a ii-story house, that'due south vi,500 square feet. Most lots in Denver are more than similar 5,000 to 7,500 foursquare feet, and and so most houses with pop tops have them because their footprint was maxed out at around 2,000 square feet.
The other constraint is what's chosen the bulk plane envelope, which you can visualize past imagining a tent, with 45-caste roofs, over a house. In most Denver residential zoning classifications, the tent tin can have a peak tiptop of xxx feet, but at the property lines, the summit summit is about 17 feet. The newly expanded house has to fit within that tent.
In Denver, do you take to bring the entire business firm upwardly to code once you lot start calculation on?
You have to bring every area of the house, or even wall of the business firm, that yous touch up to lawmaking. But these codes aren't just there to give government code-writers something to do. Most are really well written and make a lot of sense. The free energy codes, for instance, are written so people don't accept $400-per-calendar month heating bills in the wintertime.
Are at that place other regulatory responsibilities to consider?
The homeowner typically doesn't need to exist concerned with [managing] things like plan submissions, building permits, and inspections, besides the time delivery that will exist required. These days in Denver, the timeline from submitting plans to having the permit in hand is usually about 3 months. Notwithstanding, if the firm happens to be a historic dwelling or is located in a historic neighborhood, the project also has to be approved by the urban center's Landmark Preservation Commission to ensure the add-on volition be built in accordance with the grapheme of the neighborhood. That can add a good clamper of time.
It's a big commitment. How can homeowners decide if it's correct for them?
We've had then many clients become into the process and realize it's not worthwhile considering their existing business firm merely isn't correct for them, or because other neighborhoods brand more sense, or because they merely don't want to go through the long, arduous journeying to complete the project. Simply for the clients who practice pull the trigger, the following are always the biggest reasons why:
Community. They accept a stiff bond with their neighborhood and neighbors, they honey their schools and parks and local shops, and experience this is where they want to see their family abound.
Honey for the procedure. Homeowners who really enjoy the remodels we get into are those who love going to showrooms and getting immersed in the world of options; people who really enjoy making those selections and being a part of it. For those who don't similar that procedure, the best thing to do is rent an interior designer. But it's of import to think that every terminal determination still has to be fabricated by the homeowner.
Creating a legacy. Clients who opt to pop the peak often like the idea that the changes they'll make will be enjoyed non only by their family, simply potentially past generations and families to come.
A sense of history. This is where I get to be a little bit of a romantic. I love construction and imagining the skilled craftsmen who put their claret, sweat, and tears into building these homes. At that place's a existent piece of history in each one of these Denver homes. I beloved the idea of contributing to it, and good candidates for a popular top practise besides.
