Required

The Building Department performs plan reviews, issues permits, and conducts inspections for life-safety, fire, structural, and energy code compliance. A dedicated Roofing Permit Application form is provided for reroofing projects, and a Building Permit Fee Calculator plus a published fee schedule are available on the department's site.

Inspections must be scheduled at least one business day in advance and are performed between 10am and 4pm. Electrical and plumbing inspections are not completed by the Building Department; those are handled by the State of Colorado.

The City of Alamosa has adopted the 2018 International Building Code, 2018 International Residential Code, 2018 International Mechanical Code, 2018 International Energy Conservation Code, 2018 International Fire Code, 2018 International Property Maintenance Code, and 2018 International Existing Building Code.

Required — Not separately amended by the City of Alamosa. The City adopts the 2015 IRC by reference (§ 4-21) and its 26 numbered modifications do not delete or modify Section R905.2.8.5, so the base IRC drip-edge requirement stands as adopted code. About drip edge

Required — Alamosa's amended IRC Table R301.2(1) (Alamosa Municipal Code § 4-21(2)) lists "Ice barrier underlayment: Yes" as the city's completed determination. About ice & water barrier

Not required — No City of Alamosa amendment mandates Class 4 / UL 2218 impact-resistant roof coverings. Alamosa Municipal Code § 4-21's full 26-item numbered modification list to the 2015 IRC, plus the separate 6-item 2018 IBC modification list in the same section, were read in full and contain no such addition.

Alamosa's amended IRC Table R301.2(1) (Alamosa Municipal Code § 4-21(2), which adopts the 2015 IRC with modifications) lists "Ultimate wind speed design (mph/mps): 115/51" with "Topographic effects: No," "Special wind region: No," and "Wind-borne debris zone: No," alongside "Ground snow load (lb/ft2): 30" and "Seismic design category: C" as the city's completed table.

Not separately amended by the City of Alamosa. The City adopts the 2015 IRC by reference (Alamosa Municipal Code § 4-21, 26 numbered modifications reviewed in full) and the modification list does not touch Section R907 (Reroofing) or R908 (Roof Replacement), so the base 2015 IRC roof-recover/layer-limit provisions govern as adopted; the section text itself is behind the ICC paywall and not restated here. Base-code rule, read at 2018 IRC Section R908.3.1.1 (Roof recover not allowed) and quoted here rather than left behind the ICC paywall: a roof recover "shall not be permitted" where "the existing roof has two or more applications of any type of roof covering" (nor where the existing covering is water soaked or deteriorated, or is slate, clay, cement or asbestos-cement tile). One existing layer may therefore be recovered; a second existing layer forces tear-off to the deck. The record's adopted_code names the 2018 I-Codes while this field's own text names the 2015 IRC. That disagreement is recorded rather than resolved, and it does not reach this field: the 2015 and 2018 editions carry an identical Section R908.3.1.1, so the layer answer is the same under either reading.

7.9% combined (state 2.9% + Alamosa County 3% + City of Alamosa 2%). The City of Alamosa is a home rule city that contracts with the State of Colorado for sales tax collection and reporting — so sales tax is state-collected despite the home-rule charter. Use tax, however, is filed and paid directly to the City of Alamosa (self-administered) — this is the roofing-relevant mechanism, and the City's own page explicitly names "Retailer-contractor, when acting in the capacity of a seller of building supplies, construction materials" as a covered retailer type.
