Denver city leaders are already taking steps to prepare for the expected passage of state legislation that would allow Colorado municipalities to require developers to build income-restricted housing.
Two members of the City Council, along with the cityâs Department of Community Planning and Development, have convened a task force to discuss the approach Denver should take if House Bill 1117 becomes law. So far, itâs passed the House and awaits Senate deliberation.
The bill would allow cities and towns in Colorado to require that newly constructed buildings include a certain percentage of units set aside for those making under the area median income, a designation commonly referred to as affordable housing.
The measure is a latent response to a 20-year-old Colorado Supreme Court decision known as the Telluride Decision, which ruled municipalities didnât have that power.
However, with a council that last year rejected a rezoning proposal on the grounds that a developerâs voluntary 10 percent affordable housing component was too low, the lack of a maximum cap built into the legislation has folks on the building side of the equation concerned.
âDevelopers only move forward on projects that make sense,â said Paul Books, president of Denver developer Palisade Partners and a member of the task force. âIf all of a sudden we have to take 10 percent of our units and deed restrict them at some level, and then nothing else changes, thatâs enough of an impact that many projects wonât move forward.â
Finding the right number
Books and others in his field take great pains to emphasize that thereâs a lot of nuance to the issue. But they do forecast consequences if the city doesnât take what theyâd consider a measured approach to future policies unlocked by HB 1117âs passage.
âThere are types of proposals that in our city just wonât be acceptable,â said Albus Brooks, a former city councilman who is now vice president of business development for Milender White.
Councilwoman Robin Kniech, one of the two council members on the task force, bucked the idea that the state needs to place a cap on the measure or else councils like Denverâs will go wild with power.
âThe idea that, if there are not guardrails, somehow local governments will require exorbitant percentages, is not proven out across the country,â Kniech said. âMore than a thousand of these ordinances are out there, and almost all of them cluster in the 10- to 20-percent range. Why? Because all governments think alike? No, itâs because thatâs where economics fall to be feasible to build and also be able to help contribute.â
The developers are taking a more cautious approach to the cityâs potential new powers.
âIf you look at the research, it says inclusionary housing has been shown to not freeze the supply of units and not increase the cost of market-rate housing,â Books said. âThatâs true, but most inclusionary housing has been done thoughtfully with offsets.â
Most council members, reached for comment by email, voiced support for the measure.
Councilman Paul Kashmann tossed out a number, suggesting a requirement as high as even 20 or 25 percent as a goal, to âmove the needle as far as we can without squelching construction.â Others simply expressed intentions to dive much deeper into the options.
âMost of our voluntary affordable housing agreements come in at 10 percent, and you won’t find much that is being built now above that without including some sort of public subsidy,â wrote Councilman Kevin Flynn. âIf the requirement is too high, it won’t be sustainable without public subsidy, and you’ll end up with less housing being built rather than more. Below-market rents on affordable units are offset by raising rents on the market-rate units.â
Offsets, incentives in the mix
Books and Kniech agree that in order to make this work, policymakers must strike a delicate balance. That means combining new requirements of developers with incentives and offsets of one kind or another. Height, density or parking requirements, as well as offsets to fees or other costs can slide the scale one way or another. It also means being crafty with the exact requirements themselves.
âWe test our numbers,â Kniech said. âIf we do 10 percent affordable units required for 50 percent AMI, thereâs a tradeoff. If we require 20 percent for 80 percent AMI, thereâs another tradeoff.â
How exactly the scales weigh each side is the question.
âIâm supportive of this,â said Brooks, the former city councilman. âI think the development community is supportive of more affordable housing. We want to do these things, but youâve got to make it palatable at the end of the day. It has to work financially, or the project doesnât work.â
Brooks agreed itâs much more complicated than just mandating a cap for municipalities, given all the variables. But there are numbers that, on their own, just wonât work, he said.
âThereâs no way 20 percent of every housing development in the city is going to be required for affordable housing without any offsets,â Brooks said. âI think youâre going to be looking at a number between 10 and 15 percent, and numbers weâve been hearing is for 60 percent to 80 percent AMI. But those are going to be real decision points.â
What it could mean for development
Another fear for developers is what happens to those in limbo, so to speak â the development projects that are âstuck in the middleâ between the old rules and the new. So-called âgrandfatherâ clauses, which would allow projects initiated before a rule goes into effect or a certain point thereafter to continue without having to change its scope, arenât currently required in the legislation.
Yet another concern is whom a drop in development profitability would really affect.
âIf you change inclusionary housing policy, itâs really not an impact to developers,â Books said. âItâs actually an impact to landowners. I donât think that is well understood. The reason is, for developers, if I havenât purchased the land yet, now this policy is enacted, what I do is modify my assumptions according to the new rules. If the project doesnât make sense, I wonât move forward, or Iâll wait for the market to adjust or adapt. Landowners would have to reduce their price or the market would need to adjust in other ways in order for projects to move forward.â
That has secondary impacts on local economies, Books said. If a landowner canât count on his or her land to be worth a certain amount, it changes his or her approach to spending and saving.
But more pertinently is the impact changes like this could have on the purpose of these rule changes, which is creating more housing, both affordable and otherwise.
âIt wonât necessarily freeze development,â Books said cautiously. âBut if itâs not thoughtfully done with the best practices, you increase the probability that there could be a disjointed market for a period.â
Kniech, while not unconcerned with the developersâ cautions, is a bit more bullish about the marketâs ability to adapt.
âWe have proven experience from peer cities,â she said. âMarkets do adjust. Thereâs a burst of permitting right before the law goes into effect, then the pipeline gets cleared and thereâs a drop in permitting. That doesnât show youâve killed development, it shows you cleared the pipeline. It grows again in a year or two and itâs back to comparable.â
Where it stands today
Kniech said the bigger shame, perhaps, is that Denver â and Colorado as a whole â is probably decades late on this.
âWe have missed 20 years of growth since the Telluride Decision,â Kniech said. âDuring that time, 64,000 new apartments came online, and without a tool to capture them and ensure a portion would be affordable. I think thatâs hard for communities and council members to see â that time weâve lost.â
In the meantime, Denver has worked with linkage fees, a system whereby all new development must pay the city a significant fee that is used to invest in affordable housing, and incentive programs like density and height allowances for projects including affordable units. Itâs made an impact, but it hasnât been enough, Kniech said.
âEven this tool is only one more piece of the solution,â Kniech said. âItâs a modest but steady supply. We get in fights â âinclusionary housing wonât create as many units as you think,â or âinclusionary isnât a tool for those leaving homelessness.â Well first thing is build a tool and evaluate it based on what itâs designed to do. Itâs not for creating a massive number of units, and itâs not for deeply low-income units. Itâs for a modest supply of moderate-income housing, and it does that well in places evaluating it on that basis.â
