Addition Scope · Polls
These polls ask homeowners planning a room addition, second story or ADU which route they lean toward, what problem the space solves, what budget and financing they expect, what foundation they have, where they will live during construction, and which hiring checks they skipped.
Go to the pollsEvery poll below is answered by visitors planning home additions. Results update the moment you vote, one vote per poll per browser, and your own choices stay highlighted so you can compare them with everyone else's. Nothing here is a sales survey; use it to see which trade-offs other homeowners are weighing before you request estimates.

By the numbers
Poll results above are from visitors to this site; these figures come from published research.
74%
Share of recent buyers planning to stay in their home at least two more years
TD Bank's August 2025 survey of 2,012 homeowners found 74% plan to stay put, 66% are renovating or planning to within two years, and 53% of those with a HELOC or home equity loan used it for renovations. Rate lock-in is pushing owners to add space instead of trading up.
TD Bank, Homeowners Are Staying Put and Tapping Equity Products survey (2025)18%
Secured home loans fund 18% of $50,000–$200,000 renovations
Houzz's 2025 study shows cash from savings funds 81% of large projects, secured loans such as HELOCs 18% (three times the 6% rate on small projects), cash from a home sale 19% and credit cards 26%. Addition budgets usually blend equity borrowing with savings. Houzz-user sample.
Houzz, 2025 U.S. Houzz & Home Study (2025)57.7%
Share of Midwest homes that sit over a basement (2024)
EIA's 2024 RECS microdata put 16.4 million Midwest occupied homes over a basement, 57.7% of the region's stock, against 51.6% in the Northeast, 14.2% in the West and 12.9% in the South. Nationally 29.5% of occupied homes have a basement. Installed stock, not projects.
EIA, 2024 RECS preliminary household microdata (May 2026) (2024)18%
Share of Americans living in multigenerational households (2021)
Pew Research found 59.7 million people, 18% of the U.S. population, lived in multigenerational homes in March 2021, up from 7% in 1971. Finances are the top reason, and about a third cite caregiving. 57% of adults in these homes call the experience positive.
Pew Research Center, Financial Issues Top the List of Reasons U.S. Adults Live in Multigenerational Homes (2022)National surveys tell you that 10% of renovating homeowners in Houzz's 2025 sample built an addition, that 74% of recent buyers plan to stay put, and that Pew counts 18% of Americans in multigenerational homes. They do not tell you what the person down the street planning the same rear suite is worried about, or what they cut when the bids came in high. The polls here ask those questions of the people who are planning additions right now.
The results are shares of respondents on this site and nothing more; they are not weighted, not representative, and never presented as a survey of U.S. homeowners. What they are good for is surfacing trade-offs. If most planners here worry about concealed conditions more than resale, that is a reason to read the proposal checklist on the room additions page twice. Answer a few, see the shares, and use them to sharpen the estimate request.
The first group is about the route: building out, building up, converting a garage or basement, or building a detached unit, and how sure the household is. The second is about the need: a suite, a room for a parent or adult child, an office, a bathroom, rental income. The third is about money: the all-in budget, how it will be funded, and what gets cut first if bids run high. The fourth is about the structure and the site: foundation type, whether an engineer has looked, which region the house is in.
The last group is about process: when construction should start, where the household will live during it, what worries people most, and which hiring checks they skipped or plan to skip. The order follows the site's planning sequence, so answering in order is a rough rehearsal of the decisions themselves. The quiz tests the facts behind those decisions; the polls record the choices.
As prompts, not benchmarks. If a large share of respondents say they would cut the bathroom first, remember that our analysis of EIA's 2024 survey found 38.6% of homes have one full bathroom and only 30.3% a half bath, then ask whether your plan depends on a bathroom and whether rough-in plumbing now would let you add it later. If most second-story planners have not yet had an engineer look, and you have, you are ahead; if you have not, that is the next call. If living-through answers cluster on moving out for framing, budget for it, because the second story page notes bids rarely include temporary housing.
Compare the shares with the sourced figures where they overlap. Houzz finds secured loans fund 18% of $50,000 to $200,000 projects; if the financing poll shows a much larger share here, that says something about who visits a planning site, not about the country. The gap between a self-selected poll and a national survey is the point of showing both, and the about page explains why the site keeps them separate.

Because those two facts change the answer to almost every other question. A slab house cannot assume a second story; a Northeast house on a narrow lot cannot assume a rear addition; a Midwest house over an unfinished basement should price the conversion first, since NAR puts basement conversions at 71 percent recovery and our analysis of EIA's 2024 survey finds 57.7% of Midwest homes over a basement, against 29.5% nationally. Seeing how many respondents share your foundation and region tells you how many of the other results apply to a house like yours.
The foundation poll also does a quiet job: a large share answering that they do not know what foundation they have is a reminder that a look at the crawlspace hatch or the basement wall is the cheapest planning step there is. The locations page explains what each region changes; the foundation question on the second story page explains what each foundation type allows.
The worry poll separates the fears an estimator can address from the ones only the household can. Concealed conditions, structural surprises and permit delays are answered by a survey, an engineer, a concealed-conditions clause and a realistic schedule; the service pages explain each. Resale worry is answered by Zonda's and NAR's figures and by matching finish level to the street. Money worry is answered by financing, with the MBA finding 46% of home equity borrowers citing renovations as the reason. Worry about living through construction is answered by a relocation plan and a contract that states the dates the house is unusable.
The cut-first poll is the most practical. Architect fees alone run 5–20% of the budget, per HomeAdvisor, before finishes are even chosen. Cutting finish level keeps the space and lowers the cost; cutting square footage may push the project below what solves the problem; cutting the bathroom changes what the room is; cutting design fees by using a design-build firm changes who is responsible for the drawings. Switching to a conversion route is the biggest saver where the space exists. The comparison pages show what each cut trades away, and the calculator shows what it saves.
One answer per poll per visitor, no account, no personal information collected with the vote. Results are shown immediately as shares of everyone who has answered that poll on this site. Options are written to be neutral and mutually exclusive so that the shares mean something. The polls are not a survey instrument, the sample is whoever chose to answer, and no page anywhere on the site uses a poll result as evidence about homeowners in general. When national data on the same question exists, the page shows it beside the poll and labels each.

Results appear after you answer a poll, so that the shares reflect people who considered the question rather than passers-by. Answering takes a second and records nothing about you. If you have not decided, most polls include an undecided or not-sure option, which is a legitimate answer and often the most useful share to see, since it shows how many planners are at the same stage.
So the shares are readable. Three to six neutral, mutually exclusive options let you compare at a glance; a free-text field would produce a list no one could compare. If your answer does not fit, the closest option plus the site's explanation of the trade-off is usually enough, and the contact page welcomes suggestions for options that are missing.
No. Matching uses the project description you submit on the contact page and your location. Poll answers are anonymous and are not attached to any request. Their only purpose is to show planners what other planners are weighing, and to prompt the questions you take to the site visit.
They sit beside them, labeled differently. National figures from Houzz, NAR, Zonda, Pew, AARP, EIA and the cost guides carry a source, a year and a link. Poll results are shares of respondents on this site and say so. Where both exist for the same question, seeing both is instructive: a planning site's visitors differ from the country in predictable ways.
The hiring-check poll and the biggest-worry poll. The first shows which verifications other planners skipped, which is a checklist of what not to skip: older references, license and insurance, the engineer's registration, the permit history. The second shows which fears are common, and the service pages address each with a specific clause, drawing or check to ask for.
Yes, through the contact page. Useful suggestions are questions with a small set of neutral options that planners at different stages could answer: for example, which existing room the addition opens into, or whether the household plans to phase interior finishes. Questions that ask for ratings of contractors or products are not added, because the site does not publish ratings.
The region poll lets you see how many respondents are in each region, but results are not cross-tabulated by region, since the samples are small and a breakdown would imply more precision than exists. Use the regional notes on the locations page for what actually changes by region, and the region poll simply as context for the other shares.
